Furthermore, it contains Multi-Fit Complex which comprises three types of plant-based moisturizing extracts*3 along with the moisturizing constituent glycerin. It features a somewhat thick texture and blends in readily with the skin, thoroughly moisturizing while imparting a firm, springy tautness.
