Myth #2: Collagen in creams can replenish collagen content in your skin
Truth: The molecule of collagen is too big to penetrate the skin and replenish the lack of collagen inside reticular layer of the dermis. Once applied it just lies on top. You cannot increase collagen content in the skin by applying “Collagen Creams” or taking “Collagen” in a pill form. Collagen can only be produced and replenished by the skin cells. It is completely internal process.
Using the word “COLLAGEN” on labels it is a great marketing idea. Because that is something that everybody knows and can associate with. So when you see Collagen containing cream you automatically think more firmness. But that’s is not the case. When added to creams collagen works as water-binding agent. It hydrates and prevents water loss from the surface of the skin. Also because of the way is spreads across the skin it can fill in fine lines and wrinkles, making skin to look smoother.
Bottom line is that when you see cream with collagen you can buy it. Read the label to find out the source of collagen used. Try to look for creams with Marine Collagen. But remember collagen creams will be a great hydrator and protector for your skin but it will not increase collagen content within the skin and make it firmer.
There are 4 main sources of collagen used in cosmetics and supplements:
- bovine (cows)
- chicken collagen
- porcine (pigs)
- fish (marine) collagen
Bovine, porcine and chicken collagen are cheaper and more common than fish (marine) collagen. Marine collagen has antioxidant properties that have been used in skin-care products to prevent or even repair the damage caused by environmental factors, such as UV rays and low humidity, as well as damage associated with the aging process.
P.S. If the label on the products reads ’’Stimulates or Increases Collagen and Elastin Production” that is a completely different story. It means that the product does not actually contain collagen or elastin among the ingredients, but has other components that stimulate and help the skin to produce collagen and elastin fibers.
