Key ingredients

HA4 Hydration contains four molecular weights of hyaluronic acid to help hydrate the skin at different levels. This allows it to support both surface plumping and longer-lasting hydration.

The formula is 60 times more soluble than standard hyaluronic acid, helping it deliver effective hydration while keeping the skin feeling fresh, soft and comfortable.

Good to know

Dehydrated skin can affect how your skin looks, feels and responds to the rest of your routine.

When your skin is low in hydration, it can feel tight, look dull, show fine lines more easily and feel less comfortable day to day. HA4 Hydration is designed to give the skin that extra drink of water, helping it feel softer, smoother and more supported.

It’s a lovely option if your skin feels dry or tight, but it’s also useful as part of a long-term skin health routine. Hydrated skin tends to look fresher, feel calmer and cope better with active ingredients and professional treatments.
