Frequently asked questions

Have a question? Here are the answers our customers ask most,

Six ingredients: water, pentylene glycol, phenylpropanol, sodium hyaluronate, copper tripeptide-1 (GHK-Cu, 0.10%) and sodium hydroxide. GHK-Cu helps skin look firmer, smoother and more even, with a softer look to fine lines, while 1.50% Hyaluronic Acid delivers immediate hydration. No fragrance, no silicones, vegan and cruelty-free.
Yes. It's fragrance-free with only 6 ingredients, so it fits easily into a simple routine. GHK-Cu helps skin look firmer and smoother, with a softer look to fine lines, on any skin.
It pairs well with Hyaluronic Acid moisturizers, Niacinamide (in a separate step), gentle toners and SPF. Keep strong AHAs, BHAs and high-dose vitamin C for a different step or time of day.
They're different. Retinol can leave skin dry or sensitive at first; copper peptides are gentle enough for daily use, morning or night, and help skin look firmer and smoother. Many people use both, in separate routines: copper peptides in the morning, retinol at night.
Skin feels hydrated and smooth immediately, thanks to 1.50% Hyaluronic Acid. With daily use, expect a more refined-looking surface in 3–4 weeks and visibly firmer, more elastic-looking skin in 6–8 weeks. Individual results vary.
It's fragrance-free and minimal, but if you know you're sensitive to copper, patch test first. Don't apply to broken skin, and check with your healthcare provider if you're pregnant or breastfeeding.
Apply 2–3 drops to clean, dry face and neck. Gently press and pat in until absorbed, then follow with moisturizer. In the morning, finish with SPF.
Either, or both. It's lightweight and absorbs fast with no residue, so it layers easily under moisturizer and SPF in the morning or on its own at night.
Yes. Use Copper Peptides Serum in the morning and retinol at night, or alternate nights if your skin is sensitive. Our guide, Copper Peptides + Retinol: Is It Safe to Use Both?, walks through the full routine.
The blue-green color comes from GHK-Cu, the copper peptide itself. It's a visible sign the copper peptide is in the formula.
