The first study to investigate the chemical structure of an advanced class of anti-wrinkle cream has shown that it could be used to promote wound healing and regenerative medicine.
Chemists at the University of Reading researched the nanostructure of a cosmetic ingredient used in high performance skincare creams – a peptide amphiphile (PA).
Many skincare products use peptides to treat wrinkles. Skin is made up mostly of collagen; it is the foundation that gives your skin its support and thickness. Young people have lots of collagen and taut, smooth skin. In contrast, older people have much less collagen and thin, wrinkled skin.
Collagen is protein and is made up of long chains of amino acids strung together, like chains of linked building blocks. When it is broken down, short segments form, called peptides, and these act as a signal to tell your skin it is damaged and needs to make new collagen. The new research has revealed how the chemical structure of the PA allows this to happen.
