PEPTIDES
Peptides are one of the newer ingredient groups
to hit the anti-ageing skincare scene and many
studies have shown significant results. Acting as
chemical messengers, peptides communicate with
cells to perform a specific function. They are highly
respected for their ability to penetrate the skin and
activate their target.
Peptides “turn on” the fibroblasts, which are
essential for building and repairing the skin and a
basic requirement for anti-ageing success.
Peptides are small molecules of at least two or
more amino acids chemically linked together. When
certain amino acids are combined, they create
specific peptides (the different combinations are
virtually limitless and many experts believe we
haven’t even touched the surface).
Peptides have a variety of functions, primarily they
help to stimulate collagen, combat what is known as
Advanced Glycation End (AGE) product formation,
which is a metabolic process that damages collagen
in the body, and reduce pigmentation.
The science came from the discovery that when
collagen is damaged by sunlight, it is broken up
into peptides. Certain peptides formed were able
to act as a signal to skin cells to make new collagen,
meaning we could improve wrinkled skin by
fooling the skin into thinking it had been damaged
by applying this peptide. Peptides are cellcommunicating
and can potentially trigger specific
things in the skin, so that they might improve
wrinkles, or firmness, or age spots, for example.
