PeptidesBenefits, how to use & safety
Messengers that tell skin to rebuild.
What is Peptides?
Peptides are short chains of amino acids that act as signals in skin. Different peptides do different jobs: some prompt collagen production, some relax expression lines in appearance, and copper peptides support repair. Results are subtle but they are very well tolerated.
How it works
Signal peptides such as palmitoyl pentapeptide-4 (Matrixyl) mimic fragments of collagen, nudging skin cells to produce more. Neurotransmitter-style peptides like acetyl hexapeptide-8 may soften the look of expression lines, though effects are modest.
Key benefits
- Supports skin firmness and elasticity
- Softens the look of fine lines
- Strengthens the barrier when combined with ceramides
- Gentle enough for daily use
- Fine lines
- Firmness
- Dehydration
Best suited for: All skin types, including sensitive skin, and a good retinol alternative for those who cannot tolerate it.
How to use it
Apply a peptide serum or moisturiser morning and evening after cleansing. Layer under moisturiser. Consistency over 8–12 weeks matters more than strength.
Pairs well & what to avoid
- Hyaluronic acid
- Niacinamide
- Ceramides
- Very low pH acids in the same step, which may degrade some peptides
- Copper peptides together with high-strength vitamin C in one layer
Safety & side effects
Peptides are among the best-tolerated actives. Rarely, a specific peptide or preservative may irritate. Patch test new products.
Frequently asked
Do peptides replace retinol?
No. Retinol has stronger evidence, but peptides are a gentler option and can be used alongside it.
Do peptides work like Botox?
No. Some can slightly soften expression lines, but they cannot match injectables.
Which peptide is best?
There is no single best. Look for well-studied ones like palmitoyl tripeptide-1, palmitoyl tetrapeptide-7 or copper peptides.
