Harnessing the benefits of marine algae and peptides, Collistar’s Pure Actives Two-Phase Sculpting Concentrate Intensive Treatment helps to firm the appearance of skin. The powerful formula contains two phases. In the oil phase, four types of algae seek to hydrate and smooth the skin. In the water phase, peptides work to improve the look of skin elasticity. Lightweight and quick-absorbing, the treatment promotes a sculpted look.
