When it comes to modern skincare, few ingredients have generated as much excitement as peptides. These powerful molecules play a crucial role in skin health, offering a wide range of benefits, from collagen production to hydration and even reducing hyperpigmentation. But with so many different types of peptides available, it can be overwhelming to know which ones to look for in skincare products.
In this guide, we break down the different types of peptides, their benefits, and where you can find them.
What Are Peptides?
Peptides are short chains of amino acids that serve as building blocks for proteins like collagen, elastin, and keratin, all essential for maintaining youthful and healthy skin. As we age, our natural peptide production declines, leading to wrinkles, sagging, and dehydration. Incorporating peptides into your skincare routine can help stimulate collagen production, enhance skin repair, and improve elasticity.
Types of Peptides and Their Benefits
- Signal Peptides (Collagen-Boosting)
These peptides stimulate collagen production, reducing fine lines and wrinkles while improving skin firmness.
𧴠Best for: Fine lines, wrinkles, loss of firmness
π¬ Examples: Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Hexapeptide-9 - Elasticity-Enhancing Peptides
These peptides help improve skin structure and resilience, making it firmer and more elastic.
𧴠Best for: Strengthening sagging skin
π¬ Examples: Tripeptide-31, Tetrapeptide-30, Palmitoyl Tripeptide-5 - Barrier-Repair Peptides
These peptides strengthen the skinβs barrier, reducing redness and irritation.
𧴠Best for: Sensitive skin, reducing redness
π¬ Examples: Palmitoyl Tripeptide-8, Acetyl Tetrapeptide-2 - Brightening Peptides
Brightening peptides help reduce hyperpigmentation, dark spots, and uneven skin tone.
𧴠Best for: Dark spots, uneven skin tone
π¬ Examples: Oligopeptide-1, Nonapeptide-1, Tetrapeptide-30, Soy & Rice Peptides - Hydration-Boosting Peptides
These peptides enhance moisture retention, keeping the skin plump and hydrated.
𧴠Best for: Deep hydration, moisture retention
π¬ Examples: Acetyl Hexapeptide-37, Palmitoyl Tetrapeptide-76. Neurotransmitter Peptides (Muscle-Relaxing)
These peptides help relax expression lines, offering a Botox-like effect without injections.
𧴠Best for: Reducing expression lines
π¬ Examples: SNAP-8 Peptide, Dipeptide Diaminobutyroyl Benzylamide - Copper Peptides (Carrier Peptides)
These peptides promote skin healing and improve elasticity, making them ideal for anti-aging and repair.
𧴠Best for: Skin regeneration, wound healing, elasticity
π¬ Examples: Copper Tripeptide-1, Manganese Tripeptide-1 - Enzyme-Inhibitor Peptides
These peptides slow down collagen breakdown, preventing fine lines and wrinkles.
𧴠Best for: Preventing collagen breakdown
π¬ Examples: Triο¬uoroacetyl Tripeptide-2, Myristoyl Pentapeptide-17 - Wound-Healing Peptides
These peptides enhance skin recovery, reducing post-inflammatory hyperpigmentation and scarring.
𧴠Best for: Healing, reducing scars
π¬ Examples: Acetyl Tetrapeptide-40, Palmitoyl Tripeptide-5 - Antioxidant Peptides
Antioxidant peptides protect the skin from pollution and oxidative stress, preventing premature aging.
𧴠Best for: Protection against environmental damage
π¬ Examples: L-Carnosine, Glutathione (GSH), RVLL (Arg-Tyr-Leu-Leu)
How to Incorporate Peptides in Your Skincare Routine
β Morning Routine: Use antioxidant peptides (like Vitamin C + peptides) for pollution protection.
β Evening Routine: Apply collagen-boosting peptides (Matrixyl, Copper Peptides) to repair and hydrate.
β Pairing: Combine peptides with hydrating ingredients like hyaluronic acid for better absorption.
β Avoid Mixing: Do not use peptides with strong acids (like AHAs) as they can degrade peptide efficacy.
Final Thoughts
Peptides are a skincare powerhouse, offering solutions for multiple skin concerns, from hydration to anti-aging and barrier repair. By choosing the right peptides for your skin needs, you can achieve firmer, healthier, and more youthful-looking skin.
