What Are Peptides in Skincare?
Peptides are small protein fragments made of amino acids that serve as building blocks for essential skin proteins like collagen, elastin, and keratin. In skincare, peptides signal the skin to boost repair, hydration, and regeneration processes.
Key Types of Peptides in Serums
1. Signal Peptides:
Stimulate collagen and elastin production.
Promote skin repair and smoothness.
2. Carrier Peptides:
Deliver essential minerals like copper to the skin, enhancing wound healing and regeneration.
3. Neurotransmitter-Inhibiting Peptides:
Reduce muscle movement, mimicking the effects of Botox for fine line reduction.
4. Enzyme-Inhibiting Peptides:
Prevent the breakdown of collagen, maintaining skin firmness.
Benefits of Peptide Serum
1. Anti-Aging:
Reduces fine lines and wrinkles by stimulating collagen and elastin synthesis.
2. Improved Skin Barrier:
Strengthens the skin’s natural defence against environmental damage.
3. Hydration:
Enhances moisture retention by boosting the skin barrier’s lipid content.
4. Skin Firmness and Elasticity:
Promotes tighter, plumper, and more resilient skin.
5. Brightening:
Minimizes pigmentation and evens out skin tone.
How to Use Peptide Serum
1. Cleanse:
Start with a gentle cleanser to remove impurities.
2. Apply Serum:
Use a small amount of peptide serum and gently massage it into the skin.
3. Layer with Other Products:
Peptide serums work well with moisturizers, hyaluronic acid, and sunscreen.
Avoid combining peptides with strong acids (e.g., AHAs, BHAs) as they may degrade the peptide's efficacy.
4. Frequency:
Use twice daily (morning and evening) for optimal results.
