Hyaluronic acid is the most popular hydrating ingredient in skincare — and quietly the most misunderstood. Used one way it makes skin plump and dewy; used another way, on a dry winter morning, it can leave skin tighter than before. The difference is one small habit almost nobody is told about.
What does hyaluronic acid actually do for skin?
Hyaluronic acid is a humectant — it binds water and holds it in the upper layers of skin, making the complexion look plumper, smoother, and more dewy. It doesn't nourish or repair on its own; its single job is to attract and retain water.
A humectant is a sponge, not a source. It can hold a remarkable amount of water relative to its weight — which is why a few drops make skin look instantly fuller. Multi-weight hyaluronic acid (small and large molecules) hydrates at more than one depth, and it's the heart of our La Crème for exactly that reason.
Do you apply hyaluronic acid to wet or dry skin?
Apply hyaluronic acid to slightly damp skin, then seal it immediately with a moisturizer. Damp skin gives the humectant water to grab; the moisturizer on top stops that water from evaporating away.
This is the whole technique, and the step people skip is the sealing. Humectant on damp skin, then a cream (or a few drops of oil like L'Élixir) to lock it — that's when hyaluronic acid delivers the plump, dewy result it's famous for.
Can hyaluronic acid dry out your skin?
Yes — in dry, low-humidity air, hyaluronic acid applied to dry skin with nothing sealed on top can pull moisture from deeper in your skin to the surface, where it evaporates, leaving skin tighter. The fix is simple: apply to damp skin and always seal it.
This is the single most useful thing to know about the ingredient, and it's why "my hyaluronic acid dries me out" is a real and common complaint in winter or on planes. The molecule isn't failing — it's doing its job with no water to grab, so it takes yours. Give it water; trap the water.
How often should you use hyaluronic acid?
You can use hyaluronic acid once or twice a day, every day — morning and/or night, after cleansing and before your moisturizer. It's gentle enough for daily use and layers well under everything else.
Because it's a hydrator rather than an active, there's no "building up tolerance" and little risk of irritation for most people. Consistency simply keeps skin looking hydrated.
Hyaluronic acid vs. glycerin — which is better?
They're both humectants and they work beautifully together, not against each other. Glycerin is smaller and pulls water effectively; hyaluronic acid holds more at the surface for that plump finish. Good moisturizers often use both.
You don't have to choose. What matters more than which humectant is on the label is whether you're sealing it in with a moisturizer over damp skin.
FAQ
Is hyaluronic acid good for oily or acne-prone skin? Yes — it's lightweight, oil-free hydration, so it suits oily and combination skin that still needs water without heaviness. Hydration and oiliness are different things.
Can you use hyaluronic acid with vitamin C, niacinamide, and retinol? Yes — it pairs safely with all of them and can actually buffer irritation from actives like retinol. Apply the thinner treatment first, then hyaluronic acid, then seal.
Does hyaluronic acid help with wrinkles? It temporarily softens the look of fine lines by plumping the skin with water; it's a smoothing, hydrating effect rather than a structural anti-aging one. For firmness over time, peptides and retinol do more.
Serum or moisturizer — which form is best? Either works; the rule is the same. If you use a hyaluronic serum, always follow with a moisturizer to seal it. A hyaluronic moisturizer like La Crème does both jobs in one step.
Why does my skin feel tight after hyaluronic acid? Almost always because it was applied to dry skin in dry air with nothing sealed on top. Apply to damp skin and lock it in with a cream, and the tightness disappears.

Hyaluronic acid does not add water to your skin. It holds water in place — and only if you give it water to hold, then seal it.
