WHAT ARE PEPTIDES?
Peptides are in every living microorganism. We have over 7,000 known peptides in the human body and they play a key role in every biological function. Simply put, a peptide is two or more amino acids in a chain. Twenty or more amino acids make up a protein, hence why Peptides are often referred to as ‘building blocks of protein’. You won’t often see protein or collagen in cosmeceuticals because the molecules are too large to be delivered to the target, hence why peptides are used.
WHAT DO THEY DO?
There are a range of different Peptides that each work on specific cell receptors to trigger a response, like a lock-and-key. In skincare they are categorized as being Carry, Signal, Enzyme Inhibiting or Neurotransmitter Inhibiting.
Peptides work to stimulate the synthesis of collagen and elastin. They speed wound healing and remove damaged cells. This results in improved skin texture and strength, as well as a reduction in redness. Cellular energy and glycosaminoglycans, (cells responsible for hydration) can also be increased, in turn aiding with barrier function and overall health of the skin. Neurotransmitter Peptides are often referred to “botox in a bottle” as they work on inhibiting muscle contractions. Although the impact of topical cosmeceuticals is not comparative to anti-wrinkle injections, clinical evidence has proven muscles are relaxed, softening fine lines and wrinkles.
HOW TO USE
In most cases, Peptides should be used twice daily and applied to the skin first before any other serums, due to their low viscosity and small molecular weight.
DON’T RELY ON PEPTIDES
Whilst Peptides provide remarkable benefits, they do not work in isolation. They must be used with other essential skin nutrients, such as Vitamin A and Vitamin C and will work the best when the skin barrier is healthy. No single Peptide is more advantageous than another, as they stimulate different cellular functions via distinctive pathways.
