Expensive anti-wrinkle creams based on collagen are a waste of money. Researchers have proven that collagens are too large to be absorbed through the skin.
Skin barrier resists collagen proteins.
According to Richard Guy, Professor at the University of Bath, cosmetics manufacturers create the idea that the anti-wrinkle substance penetrates the outer layers of skin, but this is not true. The natural skin barrier also resists these substances. While manufacturers would have us believe that approximately 60% of the cream is absorbed through the skin, reality is otherwise. Nearly all of the product remains on the surface.
Collagen is a protein that gives the skin strength and elasticity.
Collagen is regarded as the best ingredient to smooth wrinkles from within. Because the amount of natural collagen decreases as we grow older, collagen is included in creams and ointments. The researchers from the “Sense about Science” organization, however, have determined that the molecules based upon collagen are so large that it is impossible for them to be absorbed through the skin. Collagen proteins thus remain on the surface of the skin, waiting to be washed or wiped away.
