It is naturally rich in marine minerals and polysaccharides, which help skin hold on to moisture. This helps tired, dehydrated skin look smoother and fresher.

What is Laminaria digitata?

Laminaria digitata is a brown seaweed that grows along the cool coasts of the North Atlantic. It is one of the most widely used algae in skincare.

Is algae extract suitable for sensitive skin?

Most skin types tolerate algae extract well. If you know you react to seaweed or iodine, or your skin is very reactive, try a small area first and stop if irritation occurs.

Why use algae in a night cream?

A night cream gives ingredients hours to work while you sleep. Algae extract adds a comforting, replenishing touch, so skin looks smoother and fresher by morning.

It is light and water-loving, so it adds moisture without heaviness. Oily skin can still lack water and benefit from it.

Yes. Algae extract pairs well with oils and other moisturising ingredients. In Silky Marine Night Cream it is combined with argan oil, hibiscus and vitamin E.
