Full descriptionWhat is in the bottle · Reading the label · Who it suits · Limitations
A high-strength GHK-Cu serum for daily skin care, from the Neurogan Health copper peptide range. With consistent use it is designed to support smoother-looking texture, visible firmness, hydration and a more even-looking complexion.
What is in the bottle
- 1,200 mg GHK-Cu per bottle
- 4% concentration in 1 oz (30 mL)
- Niacinamide (vitamin B3) and kojic acid
- Aloe vera juice, glycerin and distilled water
- Jojoba, papaya seed and rice bran oils, and vitamin E
- Lemon peel oil and lemon essential oil
Reading the label
1,200 mg is the amount per bottle, which in 30 mL is 40 mg per mL, the 4% printed on the label.
Copper Tripeptide-1 is the ingredient-list name for GHK-Cu: glycyl-L-histidyl-L-lysine bound to copper.
Batch result. The current lot (DK25-CPD01-4) measured 1,255 mg of GHK-Cu per bottle against a 1,200 mg specification. The product strength stays 1,200 mg.
Advanced is its own formula. Our GHK-Cu Neck & Face Serum in the amber dropper bottle is a different product.
Who it suits
Adults who want to support smoother-looking texture and visible firmness, who prefer a light serum to a rich cream, and who want one product for the face, neck and décolletage.
Limitations
This is a cosmetic product, not an overnight wrinkle treatment, and not a treatment for any skin condition.
GHK-Cu works best as part of a steady routine with gentle cleansing, moisturizer and daily sunscreen. Changes are gradual, and results vary.
It contains lemon peel oil and lemon essential oil, so it is not fragrance-free.
Published GHK-Cu research is small and mostly on creams. It is not clinical evidence for this finished serum.

Niacinamide and aloe around the peptide
The copper peptide is the active. Everything else carries it, holds water at the skin surface or keeps the serum light.
COPPER PEPTIDE ACTIVE
GHK-Cu
Copper Tripeptide-1
The active, at 1,200 mg in each bottle. GHK-Cu is used in cosmetics for smoother, firmer-looking skin, and it turns the serum blue.

Natural copper peptide color
The blue comes from GHK-Cu itself, not from an added dye.
Lemon oils on the label
Lemon peel oil and lemon essential oil give the serum its scent, so it is not fragrance-free.
Paraben-free preservative
Phenoxyethanol with ethylhexylglycerin protects the water-based serum once the pump is in use.
What to expect from week 1 to week 12
Skin renews itself gradually, so judge a peptide serum over weeks, not days. Here is what each stage usually brings, with words from customers who reviewed it.
-
Day 1
Start with a photo
Before the first application, photograph your face, neck and upper chest in daylight. Compare monthly rather than daily, in the same light.
“It absorbed so quickly and the smell is amazing.” Carla W.
-
Weeks 1 to 3
Comfort and hydration first
As your skin gets used to the serum, the first changes people describe are in how it feels: more hydrated, softer and more comfortable.
“Noticed a nice healthy glow after one week of using nightly.” Nathalie L.
-
Weeks 4 to 8
Texture, for many
With daily use, many people begin to notice smoother-looking texture. This is a good point to compare photos taken in the same light.
“Around week 8 I started noticing a real change in my skin.” Hilda S.
-
Weeks 9 to 12
Fine lines and firmness
Longer use may support softer-looking fine lines and visible firmness. Results depend on age, sun exposure, routine and skin condition.
“After consistent use, I noticed a visible improvement in my skin’s overall texture.” Megan A.

Press and pat, once a day to start
Morning or evening both work. Start once a day and choose the routine you will keep.
01 · Clean skin
02 · A thin layerPress and pat it in
Pump a small amount onto your fingertips, then press and pat it over the face, neck and décolletage. It takes 1 to 2 minutes to absorb; wait until it has before the next step.
03 · FinishMoisturizer, then SPF by day
Follow with your moisturizer or our GHK-Cu face cream, and finish with broad-spectrum sunscreen in the morning.
If it pills under SPF
Pilling usually means too much serum or too little drying time. Use a thinner layer, press rather than rub, and give it the full 1 to 2 minutes to absorb before moisturizer and sunscreen. Some customers keep it for the evening.
Sensitive skin
It contains lemon peel oil and lemon essential oil. Patch test for 24 hours first, start every other day if your skin is reactive, and keep it away from your eyes.
With retinol, acids or vitamin C
Strong actives are easier in a separate routine, for example the serum in the morning and retinol at night. With prescription skin care, ask your clinician first.
Complete your routine
Pairs well with a gentle cleanser, a moisturizer or hyaluronic acid on top, and a broad-spectrum SPF 30+ every morning.
What lab testing shows, and what research can tell us
A certificate of analysis documents what was tested in one batch of this serum. Published research on GHK-Cu is a different kind of evidence: it studies the ingredient, mostly in creams, not this finished serum. See the Neurogan evidence map.
Two kinds of evidence
Lab reportTests a specific batch, ingredient or finished product.
Published researchStudies GHK-Cu generally, not this exact finished serum.
PilotLimited evidence
GHK-Cu in skincare research
Small human reports on leave-on GHK-Cu creams describe fewer visible lines and wrinkles and less laxity. The Neurogan evidence map rates this research as pilot-stage with limited evidence. These studies tested creams, not this serum.

What customers are saying
Reviews marked Verified Buyer are from confirmed purchases. They describe personal experiences with this serum and are not clinical evidence.
Individual results vary. These are customer experiences, not a clinical study.
Questions we hear most often
Hydration and softness may show first. Changes in texture, fine lines or visible firmness can take 8 to 12 weeks to judge. Results vary.
It is a separate formula in a frosted bottle with a lockable pump, and its label states 1,200 mg of GHK-Cu at 4%. The GHK-Cu Neck & Face Serum comes in amber glass with a dropper and costs less. Compare them.
Some people apply it morning and evening, but twice a day is not automatically better. Start once a day and add a second application only if your skin stays comfortable.
Yes. Let it absorb, then apply moisturizer and sunscreen before makeup.
No. No topical cosmetic permanently removes wrinkles. It may help fine lines look softer by supporting hydration and overall skin quality.
The blue comes from the copper in GHK-Cu, and the shade can vary a little between batches. If yours looks very different from your last bottle, contact us with the lot number.
No. It contains lemon peel oil and lemon essential oil, and many reviewers mention the scent.
There is no known withdrawal effect. Any cosmetic changes from steady use may fade gradually after you stop.
We offer a 30-day money-back guarantee. If you are not happy for any reason, contact us and we will give you a full refund.
