Ingredient guide
Hyaluronic acid serum
Hyaluronic acid binds water in the skin and is the fastest way to a plumper surface. But it only works when you apply it correctly — on damp skin, sealed with a moisturiser.

Why HA sometimes dries the skin
Hyaluronic acid pulls water from wherever it can find it. In a dry indoor climate — Nordic winters especially — it can draw moisture out of the deeper skin instead of the air.
The fix is simple: apply to skin that is still damp, and always seal with a cream. That way HA holds water instead of hunting for it.
Molecular weight matters
High molecular weight HA sits on the surface and smooths instantly. Low molecular weight penetrates further and supports hydration for longer.
A serum using several weights gives both the immediate plumping and the lasting hydration.
Hyaluronic acid and fine lines
Dehydration lines — the fine crepey texture that appears in the afternoon — soften quickly with HA because they are a water problem, not a collagen problem.
Structural lines need peptides or retinoids. HA makes them look softer, but it does not rebuild the skin underneath.
A routine that works
Cleanse, leave the skin damp, apply serum, then moisturiser within a minute. Sunscreen in the morning.
You do not need a separate HA serum if your peptide serum already contains it — layering more will not hydrate more.
Hydration and repair in one step
Hyaluronic acid, niacinamide and 2% GHK-Cu copper peptide in a single serum.

Can hyaluronic acid be used every day?
+
Yes, morning and night. It is non-irritating and suits all skin types, including oily and acne-prone skin.
Should HA go before or after moisturiser?
+
Before. Serum on damp skin, then cream on top to lock the water in.
Does hyaluronic acid suit oily skin?
+
Yes. Oily skin is often dehydrated, and HA adds water without adding oil.
