Layer a peptide routine thinnest to thickest: cleanse, peptide serum, moisturiser, then SPF in the morning — and keep copper peptides away from pure vitamin C.
What order should you apply peptide skincare in?
Cleanse first, then work thinnest to thickest: peptide serum, moisturiser, and SPF last in the morning. Lip balm and body products go on at the end.
Peptides are water-soluble actives, so they belong on clean, slightly damp skin where nothing is blocking them. Anything richer — a moisturiser, a body butter — goes over the top to hold that hydration in.
- Morning: cleanse → peptide serum → moisturiser → SPF
- Night: cleanse → peptide serum → moisturiser → lip balm
- Body: apply body butter to slightly damp skin after showering
Can you use two peptide serums together?
Yes. Peptide serums layer comfortably with each other — apply the thinner one first and let it absorb for around 30 seconds before the next.
A common Glo Key routine runs PDRN (Pinky Promise) for hydration and recovery, then SNAP-8 (Snatched) on expression areas, finished with a GHK-Cu moisturiser.
What should you not layer with copper peptides?
Avoid pure L-ascorbic acid (vitamin C) in the same layer as copper peptides — the two destabilise each other. Use vitamin C in the morning and copper peptides at night, or alternate days.
High-strength direct acids are the other thing to space out. If your barrier already feels reactive, drop the acid entirely for a few weeks.
How long before a peptide routine shows results?
Hydration and texture usually read first, within 2–4 weeks. Firmness, tone and the look of expression lines take longer — plan on 8–12 weeks of consistent twice-daily use.
Take a photo in the same light on day one. Skin change is gradual enough that memory is an unreliable measure.
