The unique Natural Collagen formula is a water-­based solution of collagen and elastin combined with lactic acid and cranberry extract as a natural preservative. Lactic acid is the only acid which doesn’t endanger the spatial fiber structure of the collagen, and acts as an accelerator in exfoliation and brightens the epidermis. Containing no additional coloring or fragrances, our anti-­wrinkle creams, elixirs and other skin care products are completely natural.
