Collagen Regenerating Lotion. Collagen and elastin are responsible for giving flexibility and firmness to the skin, but over time, from 25, its synthesis is considerably reduced, so it is very good topical application for stimulating collagen production. The collagen is able to penetrate to the second layer of skin, favoring the reduction and prevention of wrinkles. Thanks to its ability to cause cells to retain water, it is an excellent moisturizer for the epidermis, favoring cleaning and helping to fight free radicals and environmental pollution.
