When skin looks dull or uneven, this daily facial serum brings together a 5 PDRN blend and 200 Da hydrolyzed collagen. The PDRN blend draws from salmon, Centella asiatica, rice, Lactobacillus and sea grapes.

For moisture, eight forms of hyaluronic acid span low, medium and high molecular weights. They provide multi-layered hydration to replenish moisture and maintain a plumper, more hydrated look.

Niacinamide and Alpha-Arbutin focus on the look of uneven tone, dark spots and radiance. Panthenol and Allantoin bring another layer of care to soothe and calm sensitive skin. It is a thoughtfully rounded mix for skin that looks lacklustre, uneven or less firm.

The serum is lightweight and quick-absorbing, so its substantial ingredient story arrives with a light feel. It is intended for all skin types, including sensitive skin.
