The short answer
Apply a GHK-Cu serum to clean skin, before heavier creams and oils. It works morning or night, and daily consistency is what brings the appearance benefits over time. Keep it separate from strong direct actives like pure vitamin C or exfoliating acids — and always finish your morning routine with SPF.
Step by step
Where GHK-Cu fits in your routine
Cleanse
Start with clean skin so nothing sits between the serum and your face. Pat until just damp.
Apply your GHK-Cu serum
A few drops, pressed gently over the face and neck. As a lightweight serum, it goes on before heavier products — thin to thick is the rule.
Moisturise
Lock it in with your usual moisturiser or facial oil once the serum has settled.
SPF (mornings)
If you’re using it in the day, always finish with sunscreen — it protects the results you’re working toward.
Repeat daily
Peptides reward consistency. Use it every day and give it several weeks — that’s where the appearance benefits come from.
Pairing
What to pair it with — and what to keep apart
Plays well with: hydrators like hyaluronic acid, niacinamide, and your everyday moisturisers. Copper peptides slot easily into most routines.
Keep separate: strong, direct actives — pure vitamin C and exfoliating acids (AHAs/BHAs) — are best used at a different time of day (or on alternate days) rather than layered directly with copper peptides. A simple split is peptides in the morning, your stronger active at night.
If you also use retinol, the easiest approach is retinol at night and GHK-Cu in the morning.

How to use GHK-Cu FAQ
When should I apply GHK-Cu — morning or night?
Either works. Apply it to clean skin before heavier creams. Many people use it in the morning and keep stronger actives like retinol for the evening.
Where does GHK-Cu go in my routine?
After cleansing, before moisturiser and oils — the “thin to thick” rule. As a lightweight serum, it sits close to the skin where it’s meant to work.
Can I use GHK-Cu with vitamin C?
It’s best to keep pure vitamin C and copper peptides at different times of day or on alternate days, rather than layering them directly. A common split is peptides in the morning, vitamin C or acids at night.
How often should I use GHK-Cu?
Daily. Peptides reward consistency — regular use over several weeks is what brings the appearance benefits, not the occasional application.
Do I still need SPF?
Yes. If you use it in the daytime, always finish with sunscreen — it protects the radiance and firmness you’re working toward.
