What are peptides and what are they for?
Peptides are short chains of amino acids, which are the building blocks of proteins. In the human body, proteins play a crucial role in the structure and function of tissues. Peptides can act as cellular messengers, sending signals that promote the production of collagen, elastin and other essential skin proteins.
Peptides for the face are mainly used to improve skin firmness, elasticity and texture. By stimulating the production of collagen and elastin, peptides help reduce the appearance of wrinkles and fine lines, improving the overall appearance of the skin. In addition, some peptides have anti-inflammatory and antioxidant properties, which can help soothe irritated skin and protect against environmental damage.
Peptides in cosmetics
The inclusion of peptides in cosmetic products has revolutionized skincare. These ingredients are used in a variety of formulas, from serums and creams to cleansers and masks, thanks to their ability to deliver visible and long-lasting results.
What peptides are used in skincare?
There are several types of peptides used in skincare products, each with their own specific functions. Some of the most common ones include:
- Signaling peptides. These peptides send signals to skin cells to produce more collagen and elastin.
- Carrier peptides. They help supply essential elements such as copper and magnesium to skin cells, which can improve cellular healing and repair.
- Enzyme-inhibiting peptides. They prevent collagen breakdown by inhibiting collagen-destroying enzymes.
- Neurotransmitter peptides. They relax facial muscles and reduce the appearance of fine lines and wrinkles, working similarly to botox.
Benefits of peptides in cosmetic formulas
The benefits of peptides for the skin are many and backed by scientific studies. Including peptides in cosmetic formulas can bring visible results in a short amount of time.
Anti-aging peptides
Anti-aging peptides are particularly valued for their ability to combat the signs of aging. What exactly are these peptides for?
- Stimulating collagen production. They increase skin firmness and elasticity, reducing the appearance of wrinkles and expression lines.
- Improving the skin barrier. They help strengthen the skin's natural barrier, protecting it against harmful external factors and reducing moisture loss.
- Increasing hydration. Peptides can attract and retain moisture, which improves skin hydration and softness.
- Promoting cell renewal. They help remove dead skin cells and regenerate new ones, which can give the skin a more youthful, radiant appearance.
