Re: Pure Collagen Cream Won't Penetrate the Skin!!

thx for info...

"Collagen Conundrum
By Jennifer Tung

Cosmetics companies are bending over backward to find a cream that regenerates collagen, the basis of smooth, plump skin. The challenge: In order to stimulate new collagen, a product's active ingredients must penetrate the junction between the top layers of skin and the dermis – and that's not easy. "The epidermis itself prevents things (including collagen) from getting into the dermis," says San Francisco dermatologist Richard Glogau. "I see creams that demonstrate activity in a test tube, but it's an enormous leap to say that they'll have the same effect on skin, because the ingredients will never arrive at the right place." Especially if the main ingredient is collagen. Collagen is a large molecule. You can't put something like that through the skin topically. Even soluble collagen, which has been broken down into smaller components, may still be too large to permeate the skin. There are ingredients that dermatologists are hopeful about: Topical vitamin A (Retin-A, Renova, Tazorac, and retinol) can stimulate collagen production substantially, Glogau says. Dermatologists also report that vitamin C, copper and synthetic growth factors can be successful in boosting collagen. Until more research is done, however, the experts disagree on exactly how helpful each of these ingredients is. Bottom line: Collagen in a cream"

that is talking about skin in general ....with our lips the crusting skin is the epidermis that peels off so when our lips are raw the dermis is exposed and the collagen can be absorbed to repair it. I've used a collagen booster in the Vit C cream i've used when the skin was raw i applied it and gradually over the weeks the skin never ever gets raw. I'll still try a pure collagen cream or serum and see how my lips react.
