GHK-Cu serum and mask help
Answers for the Helloskin GHK-Cu Serum, GHK-Cu overnight mask and copper peptide bundle routine.
Copper peptide
What is GHK-Cu?
GHK-Cu is the copper peptide family used across the Helloskin GHK-Cu Serum, overnight mask and bundle routine.
What is GHK-Cu?
GHK-Cu, also written as GHKCu, is Copper Tripeptide-1: a copper-bound peptide used in cosmetic skincare for routines focused on firmer-looking, smoother-looking and more resilient-looking skin. Helloskin uses it in the GHK-Cu Serum and GHK-Cu mask system.
Is GHK-Cu the same as GHKCu?
Yes. GHK-Cu and GHKCu are two common ways people write the same copper peptide. Helloskin uses GHK-Cu on product pages because it is the clearer cosmetic ingredient spelling, but customers may search for either version.
How does topical GHK-Cu fit into a skincare routine?
Topical GHK-Cu is used as a serum step after cleansing and before moisturiser. Keep the rest of the routine simple at first so you can see how the formula feels on your skin before adding more active steps.
Products
GHK-Cu serum, mask and bundle
The serum is the daily step. The mask is the 1-4 times weekly overnight step. The bundle is for customers who want both without guessing.
When should I use the GHK-Cu Serum?
Use GHK-Cu Serum after cleansing and before moisturiser. It can sit in a morning or evening routine, but if you are layering multiple active products, keep your routine simple and introduce one new step at a time.
How often should I use the GHK-Cu overnight mask?
Use the GHK-Cu overnight mask 1-4 times per week, depending on your skin and routine. Think of it as the richer overnight support step rather than something you need to use every night.
Do I need the GHK-Cu serum and mask bundle?
You do not need both, but they are designed for different parts of the routine. The serum is the daily copper peptide step. The mask is the weekly overnight comfort step. The bundle is best if you want the full GHK-Cu system.
Compare
GHK-Cu vs PDRN
Both sit in the peptide skincare family, but they support different routine goals.
What is the difference between GHK-Cu and PDRN?
GHK-Cu is the copper peptide route for firmer-looking, smoother-looking skin. PDRN is the salmon DNA route for a hydrated, rested-looking complexion. If your routine is firmness-led, start with GHK-Cu Serum. If your routine is glow, comfort and bounce-led, start with PDRN Serum.
Can I use GHK-Cu and PDRN together?
Many routines can include both, but do not make the routine chaotic. A simple approach is to use one as the main serum step and the other on alternate nights or as part of a mask routine. Introduce products gradually.
