The Hype of Peptides in Cosmetics: What Are They and How Do They Work?

Since last year, peptides have gained popularity in the natural cosmetics industry and have positioned themselves as a favorite ingredient for both consumers and formulators. But what exactly are peptides, and why are they generating so much hype ?

What are peptides?

Peptides are short protein fragments that act as building blocks for proteins such as collagen, elastin, and keratin. These proteins are essential for maintaining skin health and vitality and play a crucial role in cosmetics for cell repair and renewal.

They can penetrate the top layer of the skin and send signals to our cells to act more efficiently, promoting deep rejuvenation from within.

How do peptides work?

When you apply a product containing peptides to your skin, you're essentially sending signals to your body to enhance certain biological processes. Some peptides promote collagen production, while others can help relax facial muscles, reducing the appearance of fine lines and wrinkles.

In terms of clean beauty , peptides stand out for offering visible results without resorting to aggressive chemicals like retinol.

Types of peptides used in cosmetics

• Signal peptides: Stimulate the production of collagen and elastin, improving skin firmness and elasticity.
• Neurotransmitter peptides: Known as “natural Botox,” they help relax facial muscles.
• Enzymatic peptides: They accelerate biological processes such as the elimination of dead cells.

What to look for in a peptide product?

If you're interested in exploring the benefits of peptide cosmetics, look for products that not only have a high concentration but are also formulated to ensure effective absorption. Prefer vehicles such as hydrogels, which allow the peptides to reach deeper layers of the skin.

Also, consider the source: There are both synthetic and natural options. Make sure the formula is designed for your skin type and goals.
