Hyaluronic acid works for every skin type -- dry, oily, sensitive, combination -- because it adds water, not oil. A good HA serum applied to slightly damp skin under your moisturizer is one of the easiest upgrades in any skincare routine. These seven are the ones worth your money.
The 7 Best Hyaluronic Acid Serums on Amazon
1. The Ordinary Hyaluronic Acid 2% + B5
Best Overall~$8-10 · ASIN: B07P5CQLBY
The Ordinary HA 2% + B5 is the benchmark HA serum -- everything else on this list is measured against it. The formula uses three different molecular weights of hyaluronic acid: high molecular weight (surface hydration and smoothing), low molecular weight (deeper penetration), and a sodium HA crosspolymer (time-released hydration). Vitamin B5 adds barrier-supporting benefits. At under $10, it performs comparably to HA serums costing $80+. The gel-like texture absorbs without residue and layers well under any moisturizer. The only serum I'd recommend without any qualification.
Pros
- Multi-weight HA for all skin depths
- Vitamin B5 barrier support
- Under $10
- Works for all skin types
Cons
- Slightly sticky until moisturizer applied
- Pipette applicator can be messy
2. CeraVe Hyaluronic Acid Serum
Best Drugstore with Ceramides~$18-22 · ASIN: B07FCTD8CZ
CeraVe's HA serum does something The Ordinary's doesn't: it combines hyaluronic acid with the brand's signature ceramide and niacinamide complex. This means you're getting hydration plus barrier repair in one step. For anyone with dry, damaged, or compromised skin (or anyone on retinol), this extra layer of barrier support makes a real difference. The texture is lightweight and absorbs cleanly. Dermatologist-formulated, fragrance-free, non-comedogenic. The price is higher than The Ordinary but justified for the added actives.
Pros
- HA + ceramides + niacinamide
- Repairs barrier while hydrating
- Fragrance-free, derm-tested
- Good for retinol users
Cons
- Pricier than The Ordinary
- Some find niacinamide irritating
3. Neutrogena Hydro Boost Water Gel
Best for Oily Skin~$18-22 · ASIN: B00NR1YQHM
Hydro Boost is the best-known HA product in the drugstore and for good reason. The water gel formula is the lightest on this list -- it absorbs almost instantly and leaves zero residue or tacky feeling. For oily skin types who find most moisturizers too heavy, Hydro Boost is often the answer. It works as both a serum and a standalone moisturizer for those who want to keep their routine minimal. The oil-free formula is non-comedogenic and has never broken anyone out in my experience. A reliable everyday choice.
Pros
- Lightest texture on the list
- Works as serum or moisturizer
- Oil-free, non-comedogenic
- Absorbs instantly with no residue
Cons
- Less intensive than dedicated serums
- Single molecular weight HA
4. La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum
Best for Sensitive Skin~$38-45 · ASIN: B08L4Y37LF
La Roche-Posay is the dermatologist's brand for sensitive skin, and the Hyalu B5 lives up to that reputation. The formula combines pure HA with Vitamin B5 and madecassoside, a soothing ingredient from the centella asiatica plant that calms redness and irritation. For anyone with reactive, rosacea-prone, or easily irritated skin, this extra layer of calming actives is worth the premium price. The texture is a light gel that layers beautifully. It's the most expensive drugstore-accessible HA serum here, but if your skin is sensitive, it earns the cost.
Pros
- Calming madecassoside for sensitive skin
- HA + B5 combination
- Dermatologist-tested formulation
- Ideal for rosacea-prone skin
Cons
- Most expensive on the list
- Overkill if your skin isn't sensitive
5. L'Oreal Paris Revitalift 1.5% Hyaluronic Acid Serum
Best Mid-Range Pick~$25-30 · ASIN: B07WM64KXZ
L'Oreal's Revitalift HA serum uses a 1.5% concentration of pure hyaluronic acid -- higher than most mid-range serums -- and delivers noticeably more intense immediate hydration than lighter formulas. The slightly denser texture makes it better suited to dry or normal skin than oily. The formula is fragrance-free (unusual for L'Oreal) and clinically tested. It sits between The Ordinary (budget) and La Roche-Posay (premium) in both price and performance. A solid middle-ground option for anyone who wants a step up from drugstore basics without pharmaceutical pricing.
Pros
- 1.5% concentrated HA formula
- Fragrance-free for a L'Oreal product
- Strong immediate hydration effect
- Good mid-range value
Cons
- Slightly heavier texture -- not ideal for oily skin
- Pricier than The Ordinary
6. TruSkin Hyaluronic Acid Serum
Best with Added Vitamins~$18-22 · ASIN: B0765KCMZZ
TruSkin's HA serum takes a kitchen-sink approach: HA plus vitamin C, vitamin B5, vitamin E, green tea, and botanical extracts. The result is a serum that does more than just hydrate -- it brightens, protects against environmental damage, and supports overall skin health. The trade-off is that the vitamin C concentration is relatively low compared to dedicated vitamin C serums, so it won't dramatically address hyperpigmentation on its own. But as an all-in-one daily serum for healthy skin maintenance, it's one of the most comprehensive drugstore options available.
Pros
- HA + Vitamins C, B5, and E
- Brightening and antioxidant protection
- Good all-in-one daily serum
- Affordable for what it does
Cons
- Low vitamin C concentration
- Not a substitute for dedicated vitamin C serum
7. Vichy Mineral 89 Hyaluronic Acid Face Serum
Best Mineral Water Formula~$35-40 · ASIN: B07MNGTWM6
Vichy Mineral 89 is formulated with Vichy's volcanic mineralizing water and 89% pure ingredients. The HA formula is designed to strengthen the skin barrier over time, not just hydrate the surface. What distinguishes it from other premium HA serums is the visible improvement in skin firmness and resilience after several weeks of use -- most HA serums provide good immediate hydration but less long-term structural benefit. The texture is a light gel that absorbs well. For anyone who wants a HA serum with a genuine long-term skin improvement benefit, Vichy earns consideration.
Pros
- Vichy volcanic mineralizing water base
- Strengthens barrier over time
- 89% pure ingredients
- Long-term skin firmness benefit
Cons
- Premium price
- Best results take 4+ weeks

Frequently Asked Questions
What does hyaluronic acid serum actually do?
Hyaluronic acid is a humectant -- it draws water from the environment into your skin and helps retain it there. Applied under moisturizer on slightly damp skin, it creates a reservoir of hydration that plumps fine lines, smooths texture, and keeps skin comfortable throughout the day. It works for all skin types including oily and acne-prone skin because it adds water, not oil.
Should I apply hyaluronic acid to wet or dry skin?
Slightly damp skin -- not soaking wet, not fully dry. Hyaluronic acid works by drawing moisture from its surroundings, so you want to give it something to work with. Apply right after cleansing while your skin is still a little dewy, then follow immediately with your moisturizer to seal the hydration in.
Can I use hyaluronic acid with retinol?
Yes, and it's one of the best combinations in skincare. Apply retinol first, then layer a hyaluronic acid serum over it to counteract dryness and irritation. Or use retinol at night and hyaluronic acid in the morning. The hydration from HA helps your skin tolerate retinol better, especially when you're first starting.
Is The Ordinary Hyaluronic Acid serum worth it?
Yes -- it's one of the best value skincare products on the market. The formula contains multiple molecular weights of HA for hydration at different skin depths, plus Vitamin B5 for additional barrier support. At under $10, it performs comparably to serums costing 5x as much. It's the one I recommend to anyone building a basic routine.
Pair your HA serum with a face moisturizer to seal in hydration. For brightening, combine with a vitamin C serum in the morning. Back to all skincare guides.
