So....13 types of peptides? Then what Are Peptides?

Peptides are short chains of amino acids, the building blocks of proteins such as collagen, elastin, and keratin. In skincare, peptides act as messengers, signaling skin cells to perform functions like repairing damage, producing more collagen, or strengthening the skin barrier. Because of this, peptides are often associated with anti-aging, firming, and hydrating effects.

Common Types of Peptides in Cosmetics

Peptides come in various forms, each with unique functions:

1. Signal Peptides

  • Function: Stimulate collagen and elastin production to reduce wrinkles and improve elasticity.
  • Example Ingredients: Palmitoyl Pentapeptide (Matrixyl), Palmitoyl Tripeptide-5, Palmitoyl Tetrapeptide-7, Tripeptide-1.
  • Example Products:
    1. The Ordinary “Matrixyl 10% + HA”
    2. Olay Regenerist Micro-Sculpting Cream
    3. Skin1004 Matrixyl 10 Boosting Shot Ampoule (Korean)
    4. COSRX “The 6 Peptide Skin Booster” (Korean)

2. Carrier Peptides

  • Function: Deliver essential minerals like copper to cells, promoting healing and regeneration.
  • Example Ingredients: Copper Tripeptide-1.
  • Example Products:
    • NIOD Copper Amino Isolate Serum
    • The Ordinary “Buffet” + Copper Peptides 1%
    • Abib Lifting Collagen Wrapping Mask (Korean)

3. Enzyme-Inhibitor Peptides

  • Function: Reduce the breakdown of collagen and elastin by inhibiting enzymes that degrade them.
  • Example Ingredients: Pentapeptides and hexapeptides targeting MMP enzymes.
  • Example Products:
    • Dr. Dennis Gross Peptide Firming Serum

4. Neurotransmitter-Inhibitor Peptides

  • Function: Relax facial muscles to reduce the appearance of fine lines and expression wrinkles.
  • Example Ingredients: Acetyl Hexapeptide-8, Dipeptide Diaminobutyroyl Benzylamide Diacetate.
  • Example Products:
    • The Inkey List Peptide Moisturizer
    • Allies of Skin Multi Peptides & GF Advanced Lifting Serum (available at Mecca)
    • Abib Lifting Collagen Wrapping Mask (Korean)

Where Do Peptides Come From?

Peptides in cosmetics can be derived from multiple sources:

  • Synthetic Peptides: Lab-created for stability and purity, widely used in modern skincare.
  • Plant-Derived Peptides: Extracted from soy, rice, or wheat proteins. Example: Rice peptides for brightening and hydration.
  • Animal-Derived Peptides: Less common today due to vegan preferences, sometimes sourced from collagen in fish or bovine sources.

Most cosmetic peptides today are synthetic or plant-derived, ensuring consistency, safety, and vegan-friendliness.

Benefits of Peptides in Skincare

Peptides offer a wide range of benefits for different skin concerns:

  1. Anti-Aging: Promote collagen production, reduce fine lines and wrinkles, and improve skin firmness.
  2. Hydration: Help maintain the skin barrier, locking in moisture and preventing dryness.
  3. Brightening: Some peptides stimulate skin repair and renewal, reducing hyperpigmentation.
  4. Healing & Repair: Speed up wound healing and reduce inflammation.
  5. Targeted Action: Depending on the peptide, they can focus on muscle relaxation, skin strengthening, or collagen protection.

Final Thoughts

Peptides are a versatile and powerful ingredient in modern skincare. Whether you’re targeting wrinkles, dullness, or dryness, incorporating peptides can help signal your skin to repair, hydrate, and rejuvenate. Products from Australian, Korean, and international brands give a wide range of options depending on your skin type and goals.

For maximum results, peptides work best in combination with other actives like hyaluronic acid, vitamin C, or niacinamide.

FAQ: Peptides in Skincare

1. What are peptides in skincare?

Peptides are short chains of amino acids that act as messengers for your skin cells. They can signal cells to produce collagen, elastin, or other proteins, helping with firmness, hydration, and overall skin health.

2. Are peptides suitable for all skin types?

Yes! Peptides are generally gentle and suitable for sensitive, dry, oily, combination, and even acne-prone skin. They do not clog pores and can support skin repair after acne treatments.

3. Can peptides help with acne-prone skin?

While peptides do not directly treat acne, they help repair damaged skin, reduce inflammation, and strengthen the skin barrier, making them excellent for post-acne recovery and reducing acne scars.

4. What is the difference between signal, carrier, and neurotransmitter-inhibitor peptides?

  • Signal peptides: Stimulate collagen and elastin production for anti-aging benefits.
  • Carrier peptides: Deliver essential minerals like copper to aid in healing and repair.
  • Neurotransmitter-inhibitor peptides: Relax facial muscles to reduce fine lines and expression wrinkles.

5. At what age should I start using peptides?

Peptides can be used from your mid-20s onward to maintain skin elasticity and prevent early signs of aging. In your 30s and 40s, they help reduce fine lines, improve firmness, and support skin repair.

6. How long does it take to see results from peptide skincare?

Visible improvements usually appear within 4–8 weeks of consistent use. Full benefits, like firmer skin and reduced fine lines, may take longer depending on age and skin condition.

7. Can I combine peptides with other active ingredients?

Yes! Peptides work well with most actives like hyaluronic acid, niacinamide, and vitamin C. Avoid layering them with strong acids (like high-concentration AHAs) in the same step, as it may reduce their effectiveness.

8. Are peptides vegan?

Most modern cosmetic peptides are synthetic or plant-derived, making them vegan-friendly. Some older formulations may use animal-derived peptides, but these are less common today.

9. Which peptides should I use for anti-aging versus brightening?

  • Anti-aging & firming: Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-5, Tripeptide-1
  • Expression lines: Acetyl Hexapeptide-8, Dipeptide Diaminobutyroyl Benzylamide Diacetate
  • Brightening: Nonapeptide-1

10. Can I use peptide masks like Abib Collagen Wrapping Mask with serums?

Yes! Masks can be used after serums or on their own to boost hydration, firmness, and peptide absorption. For best results, layer peptides consistently in your routine.

11. Do peptide cosmetics have therapeutic or medical claims?

No. Cosmetic peptide products are formulated to improve appearance, hydration, and skin texture, but they are not considered therapeutic drugs. They cannot make medical claims like curing diseases or treating severe skin conditions. Any peptide product marketed with therapeutic claims would need regulatory approval as a drug, not a cosmetic.
