Skin care: all about the benefits of peptides


The source of beauty for our skin, nails, and hair, peptides – chains made up of amino acids – call themselves our creams and serums. Focus on the key ingredient in our skincare routine.

The role of peptides

Peptides consist of two or more amino acids that are linked together to form chains. Once established, these chains fuse together to make proteins – such as collagen – that are essential for the health of the body and skin. “Peptides are a class of ingredients that ‘talk to cells,’ giving them the tools they need to function healthily and do their jobs effectively,” says Tiffany Masterson, founder of beauty brand Drunk Elephant. “Not only do they provide unique benefits to the skin, but nearly all of them help increase skin’s hydration levels. They have antioxidant and anti-inflammatory effects as a bonus.” Some peptides go even further by encouraging the natural production of collagen, the foundation of firm, plump, and radiant skin.

Why are peptides important

Playing their part, peptides take care of the health of our skin…but things get a lot more complicated around the age of 30. “We produce fewer peptides as we age. In addition, external aggressions increase the presence of enzymes that break down collagen, which leads to reduced skin elasticity and the appearance of fine lines and wrinkles, as well as uneven skin tone and texture, and uneven skin For skin, it’s a vicious cycle: fewer peptides, fewer new collagen, even when external aggressions—such as pollution, UV rays, or stress—attack existing ones. The solution? – Creams, serums, and masks – designed with peptides.”[Ces derniers] They are smaller and therefore can penetrate the skin more easily [contrairement au] Collagen, which is pretty big,” the dermatologist adds.

How to choose the right peptides

There are a large number of peptides with different benefits. Here, we keep four, which are especially important for our skin. Enzyme-inhibiting peptides block the enzymes responsible for breaking down normal collagen, while neurotransmitter peptides like Botox act by blocking the release of toxins that contribute to muscle contraction to smooth wrinkles. However, there is still no cream that can penetrate the skin as deeply as an injection. For their part, carrier peptides – particularly copper peptides – encourage collagen production, just as signal peptides, which also stimulate elastin production (on the label of our care products, one can look specifically for signals.” pentapeptide,” palmitoyl pentapeptide -4″, “tripeptide-1” or “hexapeptide”). All that remains is to take advantage of the benefits of peptides, the sources of beauty for our skin!

Benefits of peptides on hair

Peptides work also on our breasts! “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 epidermis, in order to temporarily repair and strengthen the hair fiber. “It adds volume and can be beneficial for those with fine hair,” she adds. It doesn’t take much to convince us!
