Hyaluronic acid is one of those skincare ingredients that sounds simple until you stand in front of a shelf filled with different molecular weights, peptide blends, fermented extracts, and glossy claims about “intense” hydration. I wanted to find out which formulas actually made my dry, sensitive skin feel more comfortable, rather than simply leaving a slippery film for ten minutes.
I tested 10 hyaluronic acid serums across several weeks, using them in both a simple morning routine and a richer evening routine. I looked at immediate softness, lasting hydration, tackiness, pilling, fragrance, and how each serum behaved under moisturiser and sunscreen.
The strongest formulas were not necessarily the most expensive. The winners had a sensible balance of humectants, a finish I could live with, and enough supporting ingredients to reduce water loss. A few were lovely but underwhelming, while others became reliable staples for tight, dehydrated skin.
I applied each serum to slightly damp skin after cleansing, followed by a moisturiser. This matters because hyaluronic acid is a humectant: it attracts water, but it does not create a protective seal by itself. On very dry skin, applying it without a cream or facial oil afterward can sometimes leave the face feeling tighter as the product dries.
Each serum had at least one week of regular use, with longer testing for the formulas that showed promise. I used them on my cheeks, around my mouth, and across my forehead, where dehydration usually appears first. I also noted whether a product stung on days when my eczema-prone skin barrier was unsettled.
I did not judge a serum by the size of its hyaluronic acid percentage alone. A high percentage can produce a thick, sticky texture, while a lower amount combined with glycerin, panthenol, beta-glucan, or ceramides may feel more comfortable and hydrating over time.
The results became fairly clear after the first two weeks. Hada Labo Gokujyun Premium gave the most cushion and lasting comfort, while Vichy Minéral 89 was the easiest to use every day. The Ordinary was the best low-cost option, although it needed careful application to avoid tackiness.
La Roche-Posay Hyalu B5 and Medik8 Hydr8 B5 Intense delivered a more polished experience, but the price difference did not always translate into dramatically better hydration. SkinCeuticals had the most treatment-like finish and a useful blend of supporting ingredients, though it is difficult to justify for anyone shopping on a budget.
| Serum | Texture and finish | Hydration result | Best suited to |
|---|---|---|---|
| Hada Labo Gokujyun Premium | Rich, silky, slightly tacky | Excellent and long-lasting | Very dry skin |
| Vichy Minéral 89 | Lightweight gel | Very good and comfortable | Daily dehydrated skin |
| The Ordinary HA 2% + B5 | Thick gel | Good, with a light film | Budget routines |
| La Roche-Posay Hyalu B5 | Cushiony gel-serum | Very good | Dry, sensitive skin |
| Medik8 Hydr8 B5 Intense | Smooth, elegant gel | Excellent | Dehydration and fine lines |
| SkinCeuticals HA Intensifier Multi-Glycan | Dense serum | Excellent | Mature or very dry skin |
| Drunk Elephant B-Hydra | Light, fresh gel | Good | Normal to combination skin |
| The Inkey List Hyaluronic Acid | Thin, easy gel | Good | Beginners |
| NIOD Multi-Molecular Hyaluronic Complex | Watery and layered | Very good | Ingredient-focused routines |
| Revolution Skincare 2% Hyaluronic Acid | Slippery gel | Moderate to good | Simple affordable routines |
Hada Labo Gokujyun Premium was the most convincing option when my skin felt rough, tight, or visibly dehydrated. It has a plush, almost essence-like consistency and leaves the skin looking more rested immediately. The finish is dewy rather than matte, so I preferred it at night or under a richer moisturiser.
Its main strength was persistence. My skin still felt comfortable the following morning, which was not true of every lightweight serum in the test. It also worked well on flaky areas without stinging. The only drawback is the sticky finish if too much is applied, so one or two small drops are enough.
La Roche-Posay Hyalu B5 was a close second for sensitive skin. It felt more substantial than Vichy but less dense than Hada Labo, and it layered neatly beneath a barrier cream. I found it particularly useful during colder weather, when my cheeks needed hydration without a facial oil every night.
Vichy Minéral 89 was the easiest serum to reach for. It has a clean, lightweight gel texture that spreads quickly and leaves very little residue. It made my skin feel softer without making it shiny, which helped it sit comfortably beneath sunscreen and makeup.
This is the formula I would choose for someone who wants a straightforward hyaluronic acid product and dislikes a heavy or sticky finish. It did not provide the same deep comfort as Hada Labo, but it was more forgiving in a busy morning routine. I could also use it around the nose and mouth without the slight tackiness becoming noticeable.
The Inkey List Hyaluronic Acid performed in a similar category, with a thinner texture and a more accessible price. It gave my skin a fresh, hydrated feel, although I needed to seal it promptly with moisturiser. It is a sensible starting point for anyone new to humectant serums, especially if the rest of the routine is already rich.
The testing notes and product photography from this project are available through the press information page, where I keep selected editorial details in one place.
For reactive skin, a hyaluronic acid serum is only helpful if the complete formula is comfortable. The best options in this group were fragrance-free or very low-sensory, spread without rubbing, and did not contain a long list of potentially irritating extras. I found La Roche-Posay Hyalu B5 and Hada Labo the safest choices when my barrier was feeling fragile.
SkinCeuticals HA Intensifier Multi-Glycan gave excellent hydration and a noticeably smoother, more cushioned finish. It felt luxurious and performed well under a ceramide cream, but its high price makes it a targeted purchase rather than an automatic recommendation. I would reserve it for skin that is persistently dry or showing dehydration lines.
NIOD Multi-Molecular Hyaluronic Complex was interesting because it felt more watery and layered than a standard gel serum. It absorbed quickly and left my skin comfortable, though the experience was less immediately plush. It suited days when I wanted hydration without adding much weight to a routine.
Any serum can irritate compromised skin, even one marketed for sensitive complexions. During an eczema flare, I would keep the routine deliberately plain: gentle cleanser, bland moisturiser, and sunscreen in the morning. A new hydrating serum can wait until the skin feels calm again.
The Ordinary HA 2% + B5 was the clearest budget winner. It is thicker and stickier than Vichy, but it gave good hydration for the price and made dry patches look less obvious. The key is using a very small amount on damp skin, then pressing in moisturiser before the surface becomes tacky.
Revolution Skincare 2% Hyaluronic Acid was pleasant but less impressive. It offered a quick boost of softness and worked well under makeup, yet the hydration faded sooner. It would suit someone who wants a simple, inexpensive serum for occasional use rather than a major treatment step.
Drunk Elephant B-Hydra was lightweight, fresh, and easy to combine with other products. It did not deliver the richest hydration in the group, but it was a good fit for normal, combination, or mildly dehydrated skin. My dry cheeks needed an additional cream, while my forehead was happy with the lighter finish.
For a personal routine, the difference between an affordable and premium product often comes down to texture and supporting ingredients. Hyaluronic acid itself is not an expensive ingredient, so a higher price should bring a more elegant formula, better packaging, or a broader approach to barrier support.
The application method made almost as much difference as the product. A damp face gave every serum a smoother spread, while completely dry skin made the thicker formulas feel more concentrated and sticky. I applied two or three drops, waited briefly, and followed with a moisturiser while the serum still felt slightly hydrated.
These are the formulas and habits I would prioritise:
A facial oil can be added last if the skin still loses moisture overnight, but it is not a replacement for cream. Oils help reduce water loss; they do not supply the water-binding effect of a humectant. In winter, the most comfortable routine for me was serum, moisturiser, and a few drops of squalane on the driest areas.
For readers looking for tailored product testing, ingredient notes, or editorial enquiries, the best route is the contact page. I continue to favour routines that feel realistic, especially for skin that needs consistency more than constant product changes.
After testing all 10, my shortlist is simple: Hada Labo for deep comfort, Vichy for everyday use, La Roche-Posay for sensitive skin, and The Ordinary for an effective low-cost option. Start with one serum, apply it correctly, and give your moisturiser the final job of keeping that hydration where your skin needs it.
