Hyaluronic acid is the most popular humectant in skincare. But it is bound up with a mistake that ruins half of all routines: used incorrectly, it dries the skin more than going without it. Let us work out how this happens and how to do it right.
Hyaluronic acid draws water into the skin, but does not hold it there itself. Without a cream on top in dry air, it pulls moisture from the deeper layers up to the surface — and the skin becomes drier. Apply it to damp skin and seal it in at once with a cream.
01What hyaluronic acid is
Hyaluronic acid is a humectant: a molecule that draws and holds water in the outer layer. It can bind water many times its own weight, and it lends the skin plumpness and radiance. It is present in the skin naturally, but there is less of it with age.
02The main catch: without an occlusive it dries
Here is what matters to understand. A humectant draws water from wherever it can — from the air, if it is humid, or from the deeper layers of the skin, if the air is dry. In a dry climate, hyaluronic acid without a cream on top pulls moisture from the depths to the surface, from where it evaporates. The result — skin drier than it was.
The solution is simple: after a humectant, always apply a cream or occlusive (squalane, ceramides) that "closes the door" and keeps the water from leaving. This turns hyaluronic acid from a risk into a working tool.
03Low and high molecular weight: the difference
Hyaluronic acid comes in different molecule "sizes":
- High molecular weight — stays on the surface, forms a hydrating film, gives instant smoothness.
- Low molecular weight — penetrates deeper, hydrating within the deeper parts of the outer layer.
- Multi-molecular (a combination) — the best option: it hydrates at different levels at once.
04How to use it correctly
- Apply to slightly damp skin — that way the humectant has something to draw on.
- Seal it in with a cream at once — this step is essential.
- In a dry climate, run a humidifier — the more humid the air around, the better.
- It suits any skin type, including oily and dehydrated.
- Do not expect a "filler" effect: HA hydrates and visually smooths, but it does not fill wrinkles permanently.
05Expensive does not mean better
What matters is not the price but the concentration and the formula. A premium serum costing a great deal may contain the same ~1% hyaluronic acid as a budget one — the difference is often in texture, packaging and marketing, not in effectiveness. In the ingredient list (INCI), ingredients appear in descending order of mass only down to 1%, so "high in the list" does not always mean "a lot".
06Common questions
Why has my skin become drier after hyaluronic acid?
Most likely you did not seal it in with a cream. Without a cream on top in dry air, HA pulls moisture from the deeper layers up to the surface, from where it evaporates. Always apply a cream after a humectant.
Apply to dry or damp skin?
To slightly damp skin — that way the humectant has something to draw on from the very top layer. Then a cream at once.
Is hyaluronic acid suitable for oily skin?
Yes. It is a light, non-comedogenic humectant. Oily skin can be dehydrated too, and HA helps without weighing it down.
Does hyaluronic acid remove wrinkles?
It hydrates and visually smooths fine lines by filling them with moisture, but this is a temporary cosmetic effect, not permanent smoothing.
