Peptides are small chains of amino acids that play a pivotal role in maintaining skin health. As a dermatologist, I often see patients curious about how peptides can improve their skincare routine, particularly for anti-aging. This article will help you understand peptides, their types, benefits, and how to choose products featuring them.

What Are Peptides?

Peptides are short chains of amino acids linked by peptide bonds, acting as signaling molecules that influence various skin functions, such as collagen production and skin repair.

Types of Peptides in Skincare

Peptides are categorized into four types, each offering unique benefits:

1. Signal Peptides

Function: Stimulate collagen, elastin, and other matrix protein production, making skin firmer and younger-looking.

Examples:

• Glycyl-Histidyl-Lysine (GHK-Cu): Enhances collagen synthesis and has antioxidant properties.
• Palmitoyl Pentapeptide-4 (Matrixyl): Improves skin elasticity and reduces wrinkles.
• Tripeptide-10 Citrulline: Offers firming effects by binding to collagen fibrils.
• Syn-Coll: Promotes collagen formation and reduces fine lines.

2. Enzyme-Inhibitor Peptides

Function: Prevent the breakdown of collagen, maintaining skin elasticity.

Examples:

• Soybean Protein: Acts as an anti-aging agent while moisturizing and soothing the skin.
• Rice Peptides: Reduces enzyme activity that breaks down collagen and promotes hydration.
• Silk Protein: Offers antioxidant properties and binds effectively with minerals like copper.

3. Neurotransmitter-Inhibitor Peptides

Function: Reduce muscle contractions to minimize expression lines, similar to Botox.

Examples:

• Acetyl Hexapeptide-3 (Argireline): Reduces wrinkle depth by relaxing facial muscles.
• Pentapeptide-18 (Leuphasyl): Relaxes muscles to decrease expression lines.
• Syn-Ake: Mimics snake venom effects to reduce wrinkles.

4. Carrier Peptides

Function: Deliver essential minerals and enhance penetration of other active ingredients.

Examples:

• Copper Tripeptide-1: Transports copper ions to promote healing and reduce inflammation.

How Do Peptides Work on the Skin?

Peptides benefit the skin through multiple mechanisms:

• Boosting Collagen Production: Peptides act as messengers, signaling fibroblasts (collagen-producing cells) to increase collagen production. This process strengthens the dermis, leading to firmer, smoother, and more youthful-looking skin.
• Calming Inflammation: Certain peptides have anti-inflammatory properties that help soothe irritated skin, reducing redness and promoting a calmer, healthier complexion.
• Strengthening the Skin Barrier: Peptides enhance the skin’s barrier function, which helps lock in moisture and shields the skin from environmental aggressors like pollution and UV radiation.
