What are peptides?

Peptides are chains of amino acids, the building blocks of proteins. These molecules are essential for various biological functions in the human body. In cosmetics, peptides play a crucial role thanks to their ability to easily penetrate the skin and interact with skin cells. Their small size allows for more efficient absorption compared to other active ingredients, making them valuable for skin care.

The benefits of peptides for the skin

Peptides provide numerous benefits for the skin, making their inclusion in beauty treatments essential. They mainly help stimulate the production of collagen, a protein essential for maintaining skin firmness and elasticity. With age, collagen production decreases, leading to wrinkles and sagging skin. Peptides help counter these effects by promoting cell regeneration and strengthening the skin barrier.

Actions on the skin

1. Reduction of fine lines and wrinkles : Peptides stimulate the production of collagen and elastin, which helps smooth wrinkles and improve skin texture.
   
   
2. Increased hydration : Certain peptides strengthen the skin barrier, allowing the skin to better retain moisture, which improves hydration and gives a plumper, radiant appearance.
   
   
3. Repair and regeneration : By promoting cellular regeneration, peptides help repair damage caused by environmental aggressions, such as UV rays and pollution.
   
   
4. Even skin tone : Peptides can also help reduce hyperpigmentation and even out skin tone, giving skin a brighter, even appearance.

Peptides or hyaluronic acid?

Hyaluronic acid is another skincare star, primarily known for its exceptional hydrating properties. It acts like a sponge, attracting and retaining water in the skin, instantly improving hydration and firmness. So, should you choose between peptides and hyaluronic acid? The answer is no. These two ingredients work wonderfully together. While peptides stimulate collagen production and repair tissue, hyaluronic acid deeply hydrates and plumps the skin. Used together, they offer a beneficial synergy for younger, firmer and well-hydrated skin.

What peptides are used in cosmetics?

There are several types of peptides used in cosmetics, each having specific functions:

1. Signaling Peptides : They send signals to skin cells to stimulate collagen production. Peptides like Palmitoyl Pentapeptide-4, also known as Matrixyl, are popular in this category.
   
   
2. Peptide transporters : They transport essential trace minerals to the skin, such as copper, which is crucial for the production of collagen and elastin. An example is Copper Tripeptide-1.
   
   
3. Enzyme inhibitor peptides : They help slow the breakdown of collagen by inhibiting the activity of the enzymes responsible for this breakdown. Palmitoyl Tripeptide-5 is a good example.
   
   
4. Neurotransmitter peptides : They can help reduce expression lines by inhibiting the release of neurotransmitters that cause muscles to contract. Argireline is a well-known peptide in this category. To find out even more on the subject, we recommend this scientific article.
