Collistar presents the new frontier in dermatological and cosmetic research for a wonderful bust. Collagen + Hyaluronic Acid: two precious active ingredients used in cosmetic medicine, available in their purest form and in optimal concentrations to ensure total effectiveness, localized effects, and exceptional safety. A few drops a day is all you need for fast, safe, and long-lasting results. Collagen, the skin's natural support system, helps: Make the tissues of the bust firmer and more compact; Fight loss of tone and elasticity in the skin; Prevent sagging and stretch marks. Hyaluronic acid, the ultimate super moisturizer, helps maintain firmness and smoothness in the skin of the bust area through three actions: Lifting effect on the skin surface (high molecular weight hyaluronic acid); Tightens the dermo-epidermal junction (medium molecular weight hyaluronic acid); Stimulates the metabolism of skin cells in depth (low molecular weight hyaluronic acid).
