Hyaluronic acid

A drink, not a seal

What it does

A humectant that holds water at the skin surface for temporary plumping and comfort.

Who it suits

Nearly everyone, especially dehydrated-feeling skin in a well-rounded moisturising routine.

How to start

Apply to slightly damp skin, then seal with moisturiser. One hydrating layer is usually enough.

What it pairs with

Pairs with every active in this guide.

What to avoid

Do not expect it to replace moisturiser. In very dry air, always follow with a cream.

What to expect

Hydration feels immediate but is temporary and needs consistent use.

Evidence, honestly

Strong hydration rationale and broad formulation use, with effects depending on molecular weight and the full formula.
