SKN TO SKN Multi-Tasking Face Serum works to create a balanced complexion. Formulated with an azelaic acid derivative, this serum helps to regulate oil production and reduce blemishes. Enhanced with Astaxanthin, it brightens skin, protects against environmental stress, and boosts collagen production. Two types of peptides support skin elasticity and visibly smooth fine lines, while hyaluronic acid hydrates and plumps for a nourished feel.
