With no doubt, you already know why collagen is needed for the skin. Collagen helps the skin retain moisture, makes it elastic, and smoothes wrinkles. When applied to the skin the extract of collagen helps delay the aging process, effectively renew and rejuvenate the skin. Tight beautiful facial contour — this is another effect of the action of collagen extract. Quality skin hydration, provided by collagen extract, is necessary for the regeneration of the skin and prolonging it youthfulness. Moreover, when the skin sufficiently retains moisture, it much better produces collagen and elastin by itself, which helps to inhibit the formation of new wrinkles and fine lines. Thus, the collagen extract really helps to slow down the skin aging process and prolong its youth.
