Peptides in cosmetics: guide to understanding and using them properly

Peptides: what they are and how they work on your skin

Technically speaking, a peptide is a short chain of amino acids. In other words, several peptides join together to make an amino acid and in turn, several amino acids join together to make a protein. These protein chains work like messengers that tell your skin how it should behave. They interact with your skin and help activate different skin cell regeneration and repair processes.

That is why peptides have become key ingredients in anti-ageing cosmetics formulae. Their main function is to activate the natural production of collagen, elastin and hyaluronic acid, the three components we need to achieve firm, elastic, hydrated skin.

Moreover, since they work from the inside of our skin, they enhance:

• The production of collagen and elastin.
• Softening of wrinkles and expression lines.
• Firmness and elasticity.

How to include peptides in your beauty routine

We can include peptides in our daily beauty routine without any problems. There are many formats on the market today in which we can find those small chains of molecules.

As they are compatible with other ingredients, we can apply them along with other skincare treatments, but always taking into account the needs of our skin.

It is best to look for skincare products that include peptides in their formula. For example, the serum or gel formats are particularly effective, since these products are readily absorbed by our skin and penetrate deeper.

Furthermore, we can apply them in the morning or at night as part of our daily routine.

Having said that, we must remember to always use solar protection as the last step, since UV rays can speed up the loss of collagen. Protection is essential to keep our skin firm and healthy.

Peptides and other ingredients: effective combinations

• Hyaluronic + Peptides: The glow that your skin needs. Hyaluronic acid retains water to confer that juicy effect, while the peptides confer firmness. This creates a feeling of comfort to our skin.
• Retinoids + Peptides: The perfect pair for nighttime skincare. Retinoids renew the texture of our skin while the peptides strengthen the cutaneous barrier. Use them together at night to wake up in the morning with renewed skin.
• Antioxidants + Peptides: Protection and repair. Combine Vitamin E or melatonin with peptides for healthy, glowing skin.
