What are peptides and what do they do?

Peptides are organic molecules that consist of a chain of amino acids. Amino acids are the building blocks of proteins, and when they are linked together they form peptides or proteins. Basically, they are smaller versions of proteins as they consist of a shorter amino acid sequence.

The amino acids in a peptide are linked together by peptide bonds. A peptide bond is formed by the reaction between the carboxyl group (COOH) of one amino acid and the amino group (NH2) of another amino acid. This connection creates a peptide chain that can consist of many amino acids.

Peptides fulfill various functions in living organisms. For example, they serve as signaling molecules that transmit information from one cell to another and can regulate important processes in the body. A well-known example of a peptide is the hormone insulin, which regulates blood sugar levels.

They are also used in medical research and pharmaceuticals. Due to their specific structure and function, peptides can interact specifically with certain proteins or cells, making them potentially useful tools for the diagnosis, treatment and prevention of diseases.

Peptides play an important role in skin care as they can have various positive effects on the skin. Here are some of the most common functions of peptides in relation to the skin:

  1. Collagen production: Peptides can stimulate the production of collagen in the skin. Collagen is an important structural protein responsible for the skin’s firmness, elasticity and youthfulness. By stimulating collagen production, peptides can help improve the appearance of fine lines, wrinkles and sagging skin.
  2. Skin tightening and firming: Certain peptides can tighten and firm the skin by improving skin elasticity and reducing the appearance of sagging skin. They can also help to define facial contours and strengthen skin tissue.
  3. Moisture retention: They can help to improve moisture retention in the skin. They can bind moisture and provide the skin with adequate hydration. This can help to keep the skin supple, smooth and with a radiant complexion.
  4. Skin repair: Some peptides have reparative properties and can help restore damaged skin. They can support the healing of wounds, scars and other skin injuries.
  5. Antioxidant effect: Certain peptides have antioxidant properties and can help protect the skin from harmful free radicals. By protecting against oxidative stress, peptides can help to slow down skin ageing and reduce signs of skin damage.

They are commonly used in skincare products such as creams, serums and masks to provide these benefits and improve the overall health and appearance of the skin. However, it is important to note that the effectiveness of peptides depends on their specific composition, concentration and application.
