My skin used to drink up moisturizer and still feel tight two hours later.
I’d slather on cream after cream, wondering why nothing lasted. Then a skincare-obsessed friend asked me one question that changed everything: “Are you using hyaluronic acid?”
I wasn’t. I didn’t know what it was.
Three weeks after adding a hyaluronic acid serum to my routine, my skin went from perpetually dehydrated to plump and glowing. The difference was so obvious that my coworker asked if I’d gotten a facial.
Nope. Just finally figured out what my skin was missing.
If your moisturizer isn’t cutting it, if your skin looks dull no matter what you do, or if fine lines seem deeper than they should be, you probably need hyaluronic acid. It’s not magic, but it’s pretty close.
I tested 10 of the most popular hyaluronic acid serums on Amazon – from $8 budget options to $30 premium formulas. Here’s what actually works.
💡 For glowing, plump skin, pair your hyaluronic acid with a gentle retinol serum to balance hydration and renewal.
Quick Picks: Too Long; Didn’t Read
Best Overall: The Ordinary Hyaluronic Acid 2% + B5 ($9.90)
Affordable, effective, and works for everyone. 27,000+ five-star reviews don’t lie.
Best Premium: La Roche-Posay Hyalu B5 ($29.99)
Worth the splurge if you want visible plumping results fast. Amazon’s choice for a reason.
Best for Mature Skin: Coera Hyaluronic Acid Serum ($8.29)
Specifically formulated for women over 50. Incredible value.
Best with Vitamin C: L’Oréal Revitalift 1.5% Pure HA ($22.17)
Hydration + anti-aging in one. Clinical results prove it works.
Best Korean Beauty: Torriden DIVE IN ($24)
48-hour lasting hydration with 5D multi-molecular HA. K-beauty at its finest.
Now let’s dive into the details.
What is Hyaluronic Acid (And Why Your Skin Needs It)
Quick science lesson:
Hyaluronic acid (HA) is a molecule that holds up to 1,000 times its weight in water. Your body naturally produces it, but production drops as you age – especially after 30.
Think of it like a sponge. When your skin has enough hyaluronic acid, it’s a wet, plump sponge. When you’re low on HA? Dry, shriveled sponge.
What it does:
- Pulls moisture from the air into your skin
- Holds that moisture in place
- Plumps up fine lines temporarily
- Makes other products work better
- Creates that “glass skin” glow
What it doesn’t do:
- Replace moisturizer (you still need cream on top)
- Works alone (needs moisture to grab)
- Erase wrinkles permanently
- Work instantly (takes 2-4 weeks for full results)
I learned this the hard way when I first tried HA serum on dry skin in a dry room. It actually made my skin feel tighter! You need to apply it to damp skin so it has moisture to lock in.
More on that later.
For deeper repair, pair hydration with exosome serums that signal cellular rejuvenation.
The 10 Best Hyaluronic Acid Serums (Tested & Reviewed)
1. The Ordinary Hyaluronic Acid 2% + B5 – The Budget Champion
Price: $9.90
Rating: 4.7 stars (26,756 reviews)
Key Ingredient: 2% pure hyaluronic acid + vitamin B5 + ceramides
Best For: Everyone, especially beginners
My Rating: 10/10
This is the one that converted me to hyaluronic acid.
What makes it special:
For under $10, you get pharmaceutical-grade hyaluronic acid at an effective concentration. The Ordinary doesn’t waste money on fancy packaging or marketing – they put it all into the formula.
The texture is like thick water. Sounds weird, but it’s perfect. Not sticky, not slimy, just perfect hydrating. It sinks in within 30 seconds, leaving your skin feeling plump and ready for moisturizer.
The added vitamin B5 (panthenol) helps with healing and calming, and the ceramides support your skin barrier. It’s not just hydration – it’s actually improving your skin’s ability to hold moisture long-term.
What I love:
The price-to-performance ratio is unbeatable. I’ve used $60 serums that don’t work as well. The dropper makes application easy and hygienic. One bottle lasts about 3 months with daily use.
What’s not perfect:
The bottle is small (1 oz), so it looks like you’re not getting much. But a little goes far – you only need 3-4 drops for your whole face. Also, no fragrance, which some people miss (but fragrance in skincare is usually unnecessary irritation).
Who it’s for:
Literally everyone. If you’re new to hyaluronic acid, start here. If you’re on a budget, this is your winner. If you have sensitive skin, this won’t irritate.
Real results:
After 2 weeks of twice-daily use, my forehead lines were noticeably softer. After a month, my skin texture was smoother, and my makeup sat better. After 3 months, my skin just started glowing. That’s the only word for it.
Bottom line: This is the serum I repurchase over and over. It’s in my bathroom right now. For $10, you cannot do better.
🌙 This serum works even better when layered under a vitamin C serum in the morning for that extra radiance boost.
2. ANUA Niacinamide 10% + TXA 4% Serum – The Multi-Tasker
Price: $21.90
Rating: 4.4 stars (8,794 reviews)
Key Ingredients: Niacinamide 10%, tranexamic acid 4%, hyaluronic acid
Best For: Acne-prone, sensitive skin, dark spots
My Rating: 9/10
This is technically more than a hyaluronic acid serum – it’s a full treatment serum that happens to include HA.
What makes it special:
Korean skincare brands know their stuff, and ANUA is no exception. This tackles multiple concerns at once: hydration (HA), brightening (niacinamide), dark spots (tranexamic acid), and soothing (ceramides).
Over 30,000 people bought this in the past month. That kind of popularity means it’s doing something right.
What I love:
If you have acne scarring or sun damage, the tranexamic acid visibly fades dark spots over 4-6 weeks. At the same time, the niacinamide helps with oil control and pore appearance. Additionally, the hyaluronic acid keeps everything hydrated without feeling heavy.
It’s like getting three products in one bottle.
What’s not perfect:
At $21.90, it’s more expensive than pure HA serums. The bottle is smaller (30ml vs 1 oz is standard). If you only want hydration and don’t need the other activities, you’re paying for features you won’t use.
Who it’s for:
People dealing with acne scars, hyperpigmentation, or uneven tone also need hydration. Combination or oily skin types who want a glass skin glow without greasiness.
Real results:
Users report visible fading of dark spots after 3-4 weeks. The “glass skin” effect is real – skin looks luminous and even-toned. Some people see improvement in texture and pore appearance.
Bottom line: If you want more than just hydration, this is worth the extra $12. It’s a treatment serum that happens to hydrate beautifully.

3. CeraVe Vitamin C Serum with Hyaluronic Acid – The Brightening Powerhouse
Price: $21.44
Rating: 4.4 stars (42,382 reviews)
Key Ingredients: 10% pure vitamin C, hyaluronic acid, ceramides, vitamin B5
Best For: Dull skin, anti-aging, sun damage
My Rating: 9/10
Over 20,000 people bought this in the past month. CeraVe gets it right consistently.
What makes it special:
This combines the hydration of hyaluronic acid with the brightening power of 10% pure vitamin C. That’s a potent concentration – many vitamin C serums only have 5-8%.
The ceramides (CeraVe’s signature ingredient) help repair and strengthen your skin barrier while the actives do their work.
What I love:
Fragrance-free, which matters for morning use under sunscreen. The vitamin C brightens gradually but noticeably – after 4 weeks, my skin tone was more even and my old sun spots were fading.
The pump bottle is genius. No air exposure means the vitamin C stays stable longer (vitamin C degrades in air and light).
What’s not perfect:
Vitamin C can be irritating for very sensitive skin. For this reason, start slowly – every other day for the first week. More importantly, you MUST wear sunscreen with this, as vitamin C increases sun sensitivity slightly.
Who it’s for:
Anyone with dull, tired-looking skin. People with sun damage or age spots. Anyone wanting anti-aging benefits with their hydration.
Real results:
Dermatologists recommend this because it actually works. The combination of vitamin C, HA, and ceramides tackles multiple aging concerns at once. Users report brighter, more even skin tone after 2-4 weeks.
Bottom line: If dull skin is your main concern, this delivers both hydration and radiance. Well worth $21.

4. La Roche-Posay Hyalu B5 – The Premium Gold Standard
Price: $29.99
Rating: 4.6 stars (31,922 reviews)
Key Ingredients: Two types of pure HA, vitamin B5, madecassoside
Best For: All skin types, especially dry and sensitive
My Rating: 9.5/10
This is Amazon’s Choice for hyaluronic acid serum for a reason. Over 20,000 bought, and it’s the one dermatologists recommend most.
What makes it special:
La Roche-Posay uses two molecular weights of hyaluronic acid: one that penetrates deep, one that hydrates the surface. Together, this creates multi-level hydration that lasts all day.
The madecassoside (from Centella asiatica) is incredibly soothing and helps with redness and irritation. Vitamin B5 aids in healing.
What I love:
The plumping effect is visible within 15 minutes. Not kidding – you can see fine lines soften almost immediately. By week 2, the effect lasts longer. By week 4, it’s sustained even without application.
Oil-free, fragrance-free, allergy-tested, non-comedogenic. They really designed this for sensitive skin.
What’s not perfect:
It’s $30. That’s 3x the price of The Ordinary. The bottle is also small (1 oz), so you’re definitely paying premium prices.
Is it better than The Ordinary? Marginally. Is it 3x better? That’s debatable.
Who it’s for:
People who want luxury skincare that actually performs. Those with very sensitive or reactive skin who need the gentlest option will find this ideal. Additionally, it appeals to anyone willing to invest in a premium product.
Real results:
Clinical studies show significant improvement in hydration, plumpness, and fine line appearance after 4 weeks—users with sensitive skin report no irritation, which is rare for active serums.
Bottom line: This is the “if money’s no object” choice. It works beautifully, but so does The Ordinary for $10.
5. SeoulCeuticals Korean Vitamin C HA Serum – The Dupe
Price: $19.98
Rating: 4.3 stars (26,074 reviews)
Key Ingredients: 20% vitamin C, hyaluronic acid, ferulic acid, vitamin E
Best For: Combination, dry, normal, oily skin
My Rating: 8/10
The marketing says it all: “same potent ingredients as more expensive CE Ferulic serums.” They’re talking about the $166 SkinCeuticals serum that dermatologists love.
What makes it special:
High-powered antioxidant serum with serious anti-aging ingredients. The 20% vitamin C is stronger than most (10-15% is standard). Ferulic acid stabilizes the vitamin C and adds its own antioxidant benefits.
It’s 98% naturally derived, 72% organic, cruelty-free, vegan, and free of sulfates and parabens. Clean beauty fans love this.
What I love:
For $20, you get a formula that rivals luxury brands. What’s more, the citrus stem cells and centella are nice bonuses for healing and calming. Plus, the texture is lightweight and absorbs fast.
What’s not perfect:
At 20% vitamin C, this can be not very pleasant for sensitive skin. Definitely do a patch test. Some users report a slight citrus scent (natural, not added fragrance). The bottle is dark glass, which is good for vitamin C stability, but makes it hard to see how much is left.
Who it’s for:
Best for people who want luxury ingredients at drugstore prices and anyone needing serious anti-aging + hydration in one product. In particular, those with normal to oily skin who can handle strong actives.
Real results:
Users report brighter skin, faded dark spots, and improved firmness after 4-6 weeks. The high vitamin C concentration means faster results than lower percentages.
Bottom line: If you want the benefits of expensive vitamin C serums without the price tag, this is it.
- THIS KOREAN SKIN CARE VITAMIN C serum contains the same potent, active ingredients as more expensive CE Ferulic Serums
- EXTREMELY EFFECTIVE – WE PROMISE you’ll begin to see results with this K beauty product within 3 weeks when used daily
- POTENT ANTI AGING, ANTI WRINKLE serum is proven to help reduce the appearance of wrinkles, fine lines & crows feet
6. COSRX Pure Vitamin C 23% Serum – The Strongest Formula
Price: $20.99
Rating: 4.1 stars (8,363 reviews)
Key Ingredients: 23% pure vitamin C, vitamin E, hyaluronic acid
Best For: Experienced users with resilient skin
My Rating: 7.5/10
A massive response of Korean beauty to aggressive anti-aging. More impressively, the 23% vitamin C concentration is among the highest you can buy.
What makes it special:
COSRX calls this the “7-day youth booster,” and while that’s optimistic marketing, users do report seeing brightness improvements within a week. The high concentration means faster visible results.
It’s lightweight and hydrating despite being a potent active serum.
What I love:
If your skin can handle it, this delivers results quickly. The texture is more oil-like than water-like, which some people prefer. It layers well under moisturizer.
What’s not perfect:
23% vitamin C is STRONG. It may cause irritation, tingling, or even peeling if you’re not careful. Not for sensitive skin, period. Not for beginners.
The 4.1-star rating (lowest on this list) reflects that some people had bad reactions. However, I can’t say it’s serum’s fault – it’s just too strong for many skin types.
Who it’s for:
People with resilient skin who’ve used vitamin C before and want maximum strength. Those who need aggressive brightening for stubborn dark spots or sun damage.
Real results:
When used correctly (start 2x per week, build up slowly), users see dramatic brightening and smoothing within 2-3 weeks. But improper use leads to irritation.
Bottom line: Only buy this if you know your skin can handle strong actives. Otherwise, stick with 10-15% vitamin C formulas.

7. Torriden DIVE IN Hyaluronic Acid Serum – The K-Beauty Star
Price: $24
Rating: 4.6 stars (2,816 reviews)
Key Ingredients: 5D multi-molecular HA, panthenol, allantoin
Best For: All skin types, especially dry and sensitive
My Rating: 9/10
Korean beauty brands understand hydration on a different level, and Torriden’s DIVE IN serum is proof.
What makes it special:
“5D multi-molecular hyaluronic acid” means they use five different molecular weights of HA. Why does this matter? Different sizes penetrate different depths of skin, thereby creating layers of hydration from deep to surface.
The result? 48 hours of lasting hydration from one application.
What I love:
The texture is gel-like but not sticky. Upon application, it feels cooling and soothing. Furthermore, the panthenol and allantoin add extra calming benefits – perfect if your skin gets red or irritated easily.
It’s hypoallergenic and works for literally all skin types. Even super oily skin benefits because hydration actually helps balance oil production.
What’s not perfect:
The bottle is small (50ml / 1.69 oz) for $24. You go through it faster than you’d like. Also, K-beauty products can be harder to restock if your local stores don’t carry them.
Who it’s for:
Ideal for K-beauty fans who want the real deal and people with dehydrated skin who need serious, lasting hydration. Specially anyone wanting that coveted “glass skin” glow.
Real results:
The 48-hour claim is real – users report waking up on day 2 with skin still feeling plump and hydrated. Over the long term, skin texture improves and looks smoother and more refined.
Bottom line: If you’re serious about hydration and love Korean skincare, this is worth the investment.

8. L’Oréal Revitalift 1.5% Pure HA Serum – The Clinically Proven Option
Price: $22.17
Rating: 4.5 stars (48,869 reviews)
Key Ingredients: 1.5% pure hyaluronic acid
Best For: All skin types, allergy-prone skin
My Rating: 8.5/10
With almost 49,000 reviews, this is one of the most-bought HA serums on Amazon. Impressively, L’Oréal’s clinical study shows wrinkles reduced by up to 47% after 6 weeks.
What makes it special:
L’Oréal doesn’t mess around with claims – they back everything with clinical studies. In this case, this serum was tested on real people with real results measured by dermatologists.
It’s dye-free, paraben-free, allergy-tested, and fragrance-free. Safe for even the most sensitive skin.
What I love:
The concentration (1.5%) is perfect – strong enough to work, gentle enough for daily use. As a result, you see immediate plumping and long-term wrinkle reduction with consistent use.
The pump bottle is hygienic and makes dosing easy. The texture is lightweight and absorbs in seconds.
What’s not perfect:
Some users wish the concentration were higher (2-3% for maximum effect). At 1.5%, it’s conservative – which is good for sensitive skin but might feel weak for experienced users.
Who it’s for:
Best for people who want proven results backed by science and those with allergies or sensitivities who need a guaranteed safe option. Equally suited to anyone wanting a reliable, no-drama serum.
Real results:
The 47% wrinkle reduction claim is from a 6-week study on moderate wrinkles. In practice, most users report visible plumping and smoothing after 2-3 weeks of consistent use.
Bottom line: Solid, reliable, clinically proven. Not the most exciting, but it works.

9. Coera Hyaluronic Acid Serum – The Mature Skin Specialist
Price: $8.29
Rating: 4.4 stars (1,930 reviews)
Key Ingredients: Hyaluronic acid (pharmaceutical grade)
Best For: Mature skin, women over 50
My Rating: 8/10
The product is specifically formulated for mature skin, which is rare. Most serums claim “all skin types” – this one targets aging skin specifically.
What makes it special:
At $8.29 for a full 8-oz bottle, this is an incredible value. In fact, that’s 8 times the amount you get in typical 1-oz serums, for the same price or less.
It’s gluten-free, non-GMO, paraben-free, and SLS-free. The formula is simple and effective – no unnecessary additives.
What I love:
The giant bottle means you can use it liberally on face, neck, chest, and hands without worrying about running out. Better yet, at this price, you can afford to be generous.
It works on skin, hair, and nails – versatility is a bonus. I use it on my cuticles and they’ve never looked better.
What’s not perfect:
The simple formula means no added vitamins or extras like other serums offer. It’s pure hydration, nothing more. The large bottle isn’t travel-friendly.
Also, with only 1,930 reviews, it’s less proven than serums with 20,000+ reviews.
Who it’s for:
Best for women over 50 who want affordable, effective hydration and budget-conscious shoppers who want maximum value. Specially anyone wanting a large bottle for body use, too.
Real results:
Users report softer, more supple skin within days. After continued use, fine lines look less pronounced after 2 weeks. Additionally, the large size means you can use it consistently without rationing.
Bottom line: Best value per ounce on this entire list. Perfect for mature skin on a budget.

Price: $9.85
Rating: 4.4 stars (27,317 reviews)
Key Ingredients: Multi-weight hyaluronic acid
Best For: All skin types
My Rating: 8/10
With over 27,000 reviews, this is clearly doing something right. It’s affordable, effective, and works for everyone.
What makes it special:
Asterwood uses the “hydration sandwich” approach – multiple molecular weights of HA that layer hydration from deep to surface. This way, it prevents moisture loss by filling gaps between skin cells.
It’s fragrance-free, absorbs quickly, and provides long-lasting hydration.
What I love:
The price-to-quality ratio is excellent. For under $10, you get results comparable to $30 serums. The texture is perfect – not too thick, not too watery.
It works for literally all skin types: combination, dry, normal, oily, and sensitive. That’s rare.
What’s not perfect:
No added vitamins or special ingredients – it’s pure HA and that’s it. If you want vitamin C or niacinamide too, look elsewhere. The 1-oz bottle is small and goes quickly with daily use.
Who it’s for:
Budget shoppers who want proven results. People with unpredictable skin who need a safe bet. Anyone wanting pure HA without extras.
Real results:
Users report immediate plumping and softness. Over 2-4 weeks, consistent use leads to improved texture, reduced fine lines, and a healthier glow.
Bottom line: Solid budget option that competes well with pricier brands. Can’t go wrong at $10.

How to Use Hyaluronic Acid Serum (The Right Way)
This is crucial – HA can actually dehydrate your skin if used incorrectly!
Step-by-Step Application
Morning Routine:
- Cleanse face with a gentle cleanser
- Pat face until it’s 80% dry (slightly damp)
- Apply 3-4 drops of HA serum to damp skin
- Press into skin, don’t rub
- Wait 1 minute for absorption
- Apply moisturizer to seal it in
- Apply SPF (always!)
Evening Routine:
- Cleanse and remove makeup
- Pat face until it’s 80% dry (slightly damp)
- Apply 3-4 drops of HA serum
- Wait 1 minute
- Apply any other treatments (retinol, etc.)
- Apply night cream to seal
Critical Rules
✅ DO:
- Apply to damp skin (this is THE most important rule)
- Use 3-4 drops for the whole face (more isn’t better)
- Layer moisturizer on top (HA needs to be sealed in)
- Use morning and night for best results
- Store in a cool, dry place away from sunlight
❌ DON’T:
- Apply to bone-dry skin (can actually pull moisture OUT)
- Use alone without a moisturizer on top
- Use in very dry climates without extra moisturizer
- Expect instant permanent results (takes 2-4 weeks)
- Use expired product (check date!)
Like retinol and vitamin C, exosome serums can complement classic actives — learn the science behind using retinol and vitamin C together here.
The Damp Skin Rule (Why It Matters)
I mentioned this earlier, but it’s so important I’m repeating it:
Hyaluronic acid doesn’t create moisture – it grabs moisture from its environment.
If you apply it to dry skin in a dry room, it will pull moisture from the deeper layers of your skin, leaving you MORE dehydrated.
But if you apply it to damp skin (or in a humid environment), it grabs that surface water and pulls it deep into your skin, then holds it there.
The difference between HA working amazingly and HA making things worse.
🧴 Apply your serum on slightly damp skin, then seal it in with a lightweight moisturizing cream to lock in the hydration.
Common Mistakes (And How to Fix Them)
Mistake #1: Using HA Alone
The problem: HA draws in moisture but doesn’t prevent evaporation
The fix: Always apply moisturizer on top to seal everything in
Mistake #2: Applying to Completely Dry Skin
The problem: HA pulls moisture from wherever it can – including deeper skin layers
The fix: Apply to skin that’s still slightly damp from cleansing
Mistake #3: Using Too Much
The problem: Wasting product and potential stickiness
The fix: 3-4 drops are enough for your entire face. More doesn’t help.
Mistake #4: Expecting Instant Results
The problem: Disappointment and quitting too soon
The fix: Give it 2-4 weeks of consistent use to see full benefits
Mistake #5: Using in Super Dry Climates Without Extra Moisture
The problem: In very dry environments (like planes or desert climates), HA can backfire
The fix: Use extra moisturizer and consider a humidifier in your room
Mistake #6: Not Wearing SPF
The problem: Many HA serums contain vitamin C or other photosensitive ingredients
The fix: Always wear SPF 30+ during the day, no exceptions
🚫 Avoid mixing too many actives at once — for stronger results, alternate with your retinol serum routine at night.
Frequently Asked Questions
Q: Can I use hyaluronic acid if I have oily skin?
Yes! Oily skin can be dehydrated. HA adds water (hydration), not oil, so it helps balance oily skin.
Q: How long does one bottle last?
With twice-daily use (3-4 drops per application), a 1-oz bottle lasts 2-3 months.
Q: Can I use HA with retinol?
Absolutely. Apply HA first (on damp skin), wait 1-2 minutes, then apply retinol, then moisturizer.
Q: Is expensive HA better than cheap HA?
Not necessarily. The Ordinary’s $10 serum performs as well as many $50+ serums. Ingredient quality matters more than price.
Q: Can I use HA morning and night?
Yes, and you should for the best results. HA is gentle enough for twice-daily use.
Q: Will HA clog my pores?
No. Pure HA is non-comedogenic (won’t clog pores). Check other ingredients if you’re acne-prone.
Q: How long until I see results?
Immediate: temporary plumping within minutes
Short-term: improved hydration within days
Long-term: reduced fine lines and better texture after 2-4 weeks
Q: Can I use HA while pregnant?
Yes! HA is considered safe during pregnancy and breastfeeding. Always check with your doctor.
Q: Does HA work in dry climates?
Yes, but you need to apply it to damp skin and seal with a heavy moisturizer. Consider using a humidifier, too.
❓ Wondering if you can use this with anti-aging products? Yes — it layers perfectly with your night cream or vitamin C serum
Final Thoughts: Which Should You Buy?
Best Overall Winner: The Ordinary Hyaluronic Acid 2% + B5 ($9.90)
If you only buy one serum from this list, make it this one. It’s affordable, effective, and works for literally everyone. I’ve repurchased it four times.
Best Premium Choice: La Roche-Posay Hyalu B5 ($29.99)
If you want luxury skincare that actually delivers, this is worth the splurge. The dual-weight HA formula is superior, and the madecassoside is incredibly soothing.
Best Value: Coera Hyaluronic Acid Serum ($8.29)
8 oz for $8.29 is an insane value. Perfect for mature skin and anyone who wants to use HA on the body, too.
Best for Anti-Aging: CeraVe Vitamin C + HA Serum ($21.44)
Hydration + brightening + ceramides = comprehensive anti-aging for $21. Hard to beat.
Best K-Beauty: Torriden DIVE IN ($24)
If you want that coveted glass skin glow, Korean beauty brands do it best. The 5D HA formula is next-level.
💖 For best results, combine this serum with a retinol and night cream duo — your skin will stay hydrated and youthful all week.
My Personal Recommendation
Start with The Ordinary ($9.90).
Use it consistently for 4 weeks. If you love the results but want something fancier, upgrade to La Roche-Posay or Torriden.
If you want more than just hydration, go for CeraVe or ANUA (both have vitamin C/ niacinamide bonuses).
If you’re over 50 or on a tight budget, Coera is an unbeatable value.
But honestly? The Ordinary is all you need.
I’ve tried serums up to $150, and I keep coming back to The Ordinary. Sometimes the affordable option really is the best.
Ready to finally get that plump, hydrated, glowing skin you’ve been wanting?
Pick your serum, remember to apply it to damp skin, seal it with moisturizer, and be consistent for at least 3 weeks.
Your skin will thank you.
