Skin is made up mostly of collagen; as we grow older we lose the collagen.
One strategy to improve wrinkles and to make you look younger is to replace lost collagen. When collagen breaks down, it forms specific peptides. These peptides act as a signal to tell your skin it is damaged and new collagen needs to be made.
Applying peptides directly to your skin is a way to trick your skin into thinking that it has lost collagen recently and needs to make more.
Because peptides are small, they can penetrate the skin’s protective barriers to get to the deeper layers. When copper is attached to a peptide, the peptide can deliver copper to the living layers of the skin. There is research showing that copper is an effective agent in skin healing which is why it has been used for years to treat chronic wounds.
So peptides can have benefits but there are many things that have to go right for this to happen. Some of them are:-
- Because they are breakdown products of proteins, they have to be stabilized or they might continue to break down further in a topical cream, becoming useless.
- They have to be in a cream that allows them to penetrate the skin. If the peptide is a thick cream that only sits on the surface, then it will never penetrate and will eventually be washed off, without any benefit.
So in conclusion peptides work when applied using a cream which meets the criteria given above.
