Showcasing an ultra-concentrated formula, Collistar’s Attivi Puri Vitamin C and Alpha-Arbutin Brightening Anti-Oxidant seeks to encourage luminous-looking skin. Featuring pure ethyl ascorbic acid, a stable Vitamin C derivative, alongside alpha-arbutin, the drops help to unify the skin tone and brighten the look of lacklustre complexions. Rich in antioxidants, the lightweight serum defends against free radicals and urban pollutants, providing a protective veil over the skin. Water-based and oil-free, the aqueous texture promotes a cooling effect upon application, making it ideal for all skin types, including sensitive.
