Below are the top 20 peptides used in skincare, created as a quick reference guide for understanding what these powerful ingredients do.
1. The Inflammatory “Off-Switch” (Acetyl Tetrapeptide-40)
This intelligent peptide acts as a messenger that tells skin cells to shut down the inflammatory cascade that leads to flushing, persistent redness, and irritation—making it ideal for reactive and rosacea-prone skin.
2. The Botox-Like Line Softener (Acetyl Hexapeptide-8 / Argireline®)
Often called “nature’s Botox,” this peptide helps relax repetitive muscle movement in the skin, visibly softening expression lines without freezing facial movement.
3. The Collagen Coach (Palmitoyl Tripeptide-1)
This peptide signals your skin to produce more collagen and glycosaminoglycans, helping rebuild firmness and smooth fine lines over time.
4. The Matrix Rebuilder (Palmitoyl Tetrapeptide-7)
A powerful partner to collagen-boosting peptides, this one reduces inflammation while reinforcing the skin’s support structure—key for aging and stressed skin.
5. The Barrier Repair Peptide (Acetyl Dipeptide-1 Cetyl Ester)
This calming peptide strengthens the skin barrier while reducing sensitivity, stinging, and reactivity—perfect for compromised or post-treatment skin.
6. The Deep Wrinkle Repair Signal (Palmitoyl Pentapeptide-4 / Matrixyl®)
One of the most studied peptides in skincare, it sends a clear signal to repair damaged collagen, helping smooth deep wrinkles and improve elasticity.
7. The Skin Density Booster (Tripeptide-10 Citrulline)
This peptide improves how collagen fibers organize themselves, enhancing firmness and skin density for a smoother, more resilient appearance.
8. The Cellular Renewal Activator (Oligopeptide-1 / EGF)
A biomimetic growth-factor peptide that encourages cell turnover and repair, supporting smoother texture and healthier, younger-looking skin.
9. The Healing Accelerator (Oligopeptide-2)
Known for its role in wound healing and regeneration, this peptide supports faster recovery and strengthens weakened skin.
10. The Elasticity Restorer (Palmitoyl Tripeptide-5)
This peptide stimulates collagen synthesis through TGF-β pathways, helping improve skin firmness and elasticity.
11. The Antioxidant Defender (Copper Tripeptide-1 / GHK-Cu)
A multitasking peptide that boosts collagen, supports healing, and neutralizes oxidative stress—excellent for aging, thinning, or damaged skin.
12. The Microcirculation Booster (Acetyl Tetrapeptide-2)
This peptide improves firmness by supporting lymphatic drainage and circulation, helping reduce puffiness and skin laxity.
13. The Pigmentation Regulator (Oligopeptide-68)
A brightening peptide that helps regulate melanin activity, making it useful for uneven tone and discoloration.
14. The Structural Support Signal (Palmitoyl Tripeptide-38 / Matrixyl® Synthe’6)
This advanced peptide targets six major components of the skin matrix, helping plump wrinkles from within.
15. The Stress-Defense Peptide (Palmitoyl Dipeptide-7)
Helps protect skin from daily stressors like pollution and UV-induced inflammation while supporting long-term resilience.
16. The Skin-Soothing Neuro-Peptide (Acetyl Hexapeptide-49)
Calms irritated nerve endings in the skin, reducing sensations of burning, itching, and discomfort.
17. The Firming Architect (Tetrapeptide-21)
Boosts collagen I production and strengthens the dermal matrix for visibly firmer, smoother skin.
18. The Hydration Optimizer (Palmitoyl Tripeptide-28)
Improves moisture retention and barrier function, helping skin stay plump and comfortable.
19. The Repair Messenger (Nonapeptide-1)
Supports skin recovery and tone correction by regulating pigmentation pathways.
20. The Longevity Peptide (Acetyl Tetrapeptide-11)
Encourages proper cell-to-cell communication and strengthens the extracellular matrix, improving overall skin integrity.
