What are peptides and what role do they play in skin care?

Peptides are amino acids that combine into short chains and act as biological messengers in the skin, stimulating the production of collagen, elastin, and hyaluronic acid.

What are peptides and how do they work?

Peptides are protein fragments made up of 2-50 amino acids. In cosmetics, they are used to send biochemical signals to the skin. When collagen levels drop (due to aging or UV exposure), collagen fragments degrade – synthetic peptides "mimic" these fragments and stimulate fibroblasts to produce new collagen.

Main types of peptides in cosmetics

• Signal peptides (Matrixyl, Syn-Coll) - stimulate collagen and elastin synthesis;
• Neurotransmitter peptides (Argireline, Leuphasyl) - inhibit muscle contraction, for a Botox-like effect;
• Carrier peptides (GHK-Cu) - transport minerals into cells, for a restorative effect;
• Enzyme-inhibitor peptides - inhibit enzymes that degrade collagen.

Proven benefits for the skin

• Reduction in the depth of expression lines;
• Increased firmness and elasticity;
• Deep hydration by stimulating hyaluronic acid;
• Even skin tone and reduction of pigment spots;
• Restorative effect after aesthetic procedures.

How to combine peptides with other ingredients?

• They combine well with: hyaluronic acid, niacinamide, antioxidants;
• Avoid direct combination with AHAs/BHAs in the same application - the acidic pH can inactivate some peptides;
• Retinol and peptides can be used on different evenings for optimal results.

Peptides have a range of benefits for the skin, as well as for the skeletal and muscular systems. A discussion with your doctor prior to administration could prevent any risks.
