Peptides are short chains of amino acids that occur naturally in our bodies. They play an important role in regulating cellular function and communication in our skin and are therefore crucial for maintaining healthy skin. In skincare, peptides are therefore used for their positive effects. For example, they can help stimulate collagen and elastin production, making skin firmer and more resilient. Peptides can also hydrate the skin and help reduce fine lines and wrinkles.
Peptides work by sending specific signals to the cells in our skin. Each peptide has a unique sequence of amino acids that determines which signal it sends to the cells. Depending on the specific signal sent, the cell can perform different functions, such as increasing collagen or elastin production, reducing inflammation or hydrating the skin. Peptides can also help reduce pigmentation and improve the skin's overall complexion. This is because peptides can also reduce the production of melanin, which can help reduce dark spots and discolouration on the skin.
There are many different types of peptides. Several types of peptides are very specific in their action and can be targeted for specific skin problems. For instance, some peptides are designed to protect the skin from oxidative stress and UV damage, while other peptides help hydrate and soothe the skin. One of the most well-known and used peptides in skincare is Argireline. This ingredient is designed to mimic the action of the muscle relaxant botox and is often used in anti-ageing creams. Argireline reduces the contraction of muscles in the face, reducing the formation of fine lines and wrinkles. Another example of a peptide used in skincare is Matrixyl. Matrixyl is a powerful peptide that helps stimulate the production of collagen and elastin in the skin. By increasing the production of these proteins, Matrixyl can help reduce fine lines, wrinkles and other signs of ageing.
One of the benefits of using peptides in skincare is that they are small enough to be absorbed by the skin and can act directly on skin cells. This is different from traditional ingredients, which only work on the outer layer of the skin and cannot penetrate the deeper layers. As you have read, peptides are effective in skincare because of their versatile action and their ability to help skin repair and renew. Cell renewal is therefore crucial for maintaining healthy, radiant skin. Promoting cell renewal allows dead skin cells to be removed, pores to remain open, skin to remain firm and complexion to remain clear and even. Peptides are not the only solution to skin problems, but they can be a good addition. There are also other ways to promote cell renewal, including regular exfoliation, protecting the skin from harmful UV rays and a healthy lifestyle.
In general, skincare products containing peptides can benefit skin with signs of ageing, fine lines and wrinkles. Dry skin can also benefit from using peptides, as this ingredient can help improve skin hydration. However, if you have sensitive skin, you should be careful when using products with peptides, as some forms of peptides can cause irritation. We therefore always recommend testing a small area of skin before using a new skincare product with peptides on the face
