Anti-aging peptides: the four classes and what they do
Not all peptides are the same. The four classes, their targets and the combinations that actually make sense.
The word peptide only tells you it is a short amino acid chain. What it does in skin depends entirely on its class.
The four classes
| Class | Example | What it does |
|---|---|---|
| Carrier peptides | GHK-Cu | Delivers copper, activates collagen synthesis |
| Signal peptides | Matrixyl | Mimics collagen breakdown signals, triggers new build |
| Neurotransmitter peptides | SNAP-8, Argireline | Dampens muscle signal, softens expression lines |
| Enzyme inhibitors | Soy peptides | Slow the enzymes that degrade collagen |
Which class for which goal
- Loss of density and elasticity: carrier peptides such as GHK-Cu.
- Expression lines on forehead and eyes: neurotransmitter peptides.
- General prevention from your mid-twenties: signal peptides.
Combine deliberately instead of stacking
The most efficient combination covers two levels at once: collagen build plus muscle signal. That is exactly how the LIORA GHK-Cu Korean Gold Serum is formulated.
See the formulaFrequently asked questions
- Which peptide works best against wrinkles?
- For loss of density, carrier peptides such as GHK-Cu act deepest; for expression lines, neurotransmitter peptides such as SNAP-8.
- Can several peptides be used together?
- Yes. Peptides from different classes act on different targets and do not interfere with each other.
- At what age do anti-aging peptides make sense?
- From your mid-twenties as prevention, from your mid-thirties as active rebuilding, when endogenous collagen synthesis measurably declines.
