Have you been hoodwinked by the “Collagen” Brigade?
Collagen has been an ingredient in skin care products for as long as I can remember. There are numerous claims to its benefits in regard to assisting the delaying of ageing and in supposedly decreasing wrinkle formation.
Many companies marketing hype revolved around the fact that they can supposedly promote a decrease in wrinkles. Recently my sister was given a sales pitch by a cosmetic company in a shopping centre. They were selling some wonder cream with Collagen, Dead sea salts and Green Tea in it. It would seem there are many consumers who are still largely uneducated and do not understand how collagen works in a cosmetic formulation.
Collagen in moisturisers are primarily used for their moisturising and plumping qualities. Collagen primarily comes from cows (bovine), or birds (avian) or fish (marine). They are water soluble only. Which means they will never enter the skin anyway.
The skin has a lipid (fat) layer. The laws of physics state that water cannot penetrate oil.
Collagen has a molecular size around 5000-9000 Daltons (Measurement of Atomic Weight for molecules). For any substance to penetrate the lipid bilayer of the skin the molecular weight needs to be less than 2000 Daltons. Collagen is clearly nowhere near this. At best collagen will just sit on the surface of the skin. Some Collagen molecules have a size of 300,000 Daltons which is incredibly large. Unless some kind of penetration enhancer is used, there is little chance of collagen actually being absorbed by the skin.
What about collagen injections?
Injecting collagen below the epidermis does provide a temporary collagen fix to the skin so to speak. This type of collagen belongs to a group of injectables known as dermal fillers. Collagen injections however DO NOT stimulate the skin to produce more collagen. Collagen in a cream has no effect on the skin producing more collagen.
The best way of stimulating collagen is with ingredients such as Vitamin A, Vitamin C and Peptides. These have all been proven to stimulate collagen production in the skin cell. Ingredients such as Matrixyl have been shown to stimulate collagen up to 350% more than normally produced by the skin. These ingredients are your best choice.
