Source of beauty for our skin, our nails, our hair, peptides – chains made up of amino acids – invite themselves into our creams and our serums. Focus on a star ingredient in our skincare routine.
The role of peptides
Peptides are made up of two or more amino acids that link together to form chains. Once created, these chains come together to make proteins – like collagen – necessary for healthy body and skin. “Peptides are a class of ingredients that ‘talk to cells’, giving them the tools they need to act healthily and do their jobs effectively,” says Tiffany Masterson, founder of beauty brand Drunk Elephant. . “Not only do they provide unique benefits for the skin, but almost all of them help to increase hydration levels in the epidermis. They have antioxidant and anti-inflammatory effects as a bonus.” Certain peptides go even further by encouraging the natural production of collagen, the basis of firm, plumped and radiant skin.
Why are peptides important
By playing their part, peptides take care of the health of our skin… but things get more complicated around the age of 30. “We produce less peptides as we age. In addition, external aggressions increase the presence of enzymes that degrade collagen, resulting in decreased skin elasticity and the appearance of fine lines and wrinkles, as well as uneven skin tone and texture. uneven skin,” says Dr. Jenny Liu, dermatologist. For the epidermis, it’s a vicious circle: fewer peptides, less new collagen, even as external aggressions – such as pollution, UV rays or stress – attack the existing one. The solution? Treatments – creams, serums, masks – designed using peptides. “[Ces derniers] are smaller and can therefore penetrate the skin more easily [contrairement au] collagen, which is too big,” adds the dermatologist.
How to choose the right peptides
There are a large number of peptides with various benefits. Here, we retain four, particularly important for our epidermis. Enzyme Inhibitor Peptides block the enzymes responsible for the breakdown of natural collagen, while Neurotransmitter Peptides act like Botox by preventing the release of toxins that contribute to muscle contraction to smooth wrinkles. That said, there is not yet a cream that can penetrate as deeply into the skin as an injection. For their part, the carrier peptides – in particular the copper peptides – encourage the production of collagen, just like the signal peptides, which also stimulate the production of elastin (on the label of our care products, one can in particular look for the mentions “pentapeptide”, “palmitoyl pentapeptide-4”, “tripeptide-1” or “hexapeptide”). All that remains is to take advantage of the benefits of peptides, sources of beauty for our skin!
The benefits of peptides on our hair
Peptides also act on our tits! “Protein loss is one of the main causes of dry, brittle hair,” says Dr. Jenny Liu. To remedy this, the expert advises betting on peptides, which penetrate the cuticle, in order to temporarily repair and strengthen the hair fiber. “They add volume and can be useful for those with fine hair,” she adds. It doesn’t take much to convince us!
