A light copper peptide serum for face and neck
GHK-Cu Copper Peptide Neck & Face Serum is a 1 oz (30 mL) serum with 1,200 mcg of GHK-Cu, also known as Copper Tripeptide-1.
An aloe base with glycerin, niacinamide and light plant oils keeps it thin enough to sit under moisturizer and SPF.
It comes in an amber glass bottle with a dropper, so you can measure out a few drops at a time.

Full descriptionWhat is in the bottle · Reading the label · Who it suits · Limitations
A lightweight, leave-on copper peptide serum for the face and neck from the Neurogan Health GHK-Cu range. With daily use it may help skin feel softer and look smoother and more even.
What is in the bottle
- 1,200 mcg GHK-Cu per bottle
- 1 oz (30 mL)
- An aloe vera juice base with glycerin and niacinamide (vitamin B3)
- Kojic acid, papaya seed, jojoba and rice bran oils, and vitamin E
- Lemon peel oil and lemon essential oil
- A paraben-free preservative (phenoxyethanol with ethylhexylglycerin)
Reading the label
1,200 mcg is the amount per bottle, not per drop. Mcg means micrograms, so 1,200 mcg is 1.2 mg.
Not the Advanced serum. The Advanced GHK-Cu Face & Neck Serum is a separate formula with 1,200 mg of GHK-Cu, in a lockable pump bottle.
Who it suits
Adults who want to add a copper peptide to a simple face and neck routine, people who prefer a light serum under moisturizer and SPF, and anyone who wants an everyday GHK-Cu serum at the lower price of our two serums.
Limitations
This is a cosmetic product, not a drug, and it is not a treatment for any skin condition.
Changes in how skin looks are gradual. Most people judge a serum after 8 to 12 weeks of daily use, and results vary.
The formula contains lemon peel oil and lemon essential oil, so it is not fragrance-free and may not suit very reactive skin.
Published GHK-Cu research is small and mostly on creams. It is not clinical evidence for this finished serum.
Copper Tripeptide-1
What GHK-Cu is
What the active is, and why it comes in amber glass.
-
01
A peptide is a short chain of amino acids. GHK-Cu is three of them, glycine, histidine and lysine, holding a copper ion. The copper is what makes the pure peptide blue.
-
02
GHK-Cu occurs naturally in the body. It has been studied in skin care for decades, mostly in creams for the face.
-
03
This serum carries 1,200 mcg in a 1 oz bottle. Amber glass shields it from light, and the dropper measures out a few drops at a time.

Natural copper peptide color
The blue comes from GHK-Cu itself, not from an added dye.
Lemon oils on the label
It contains lemon peel oil and lemon essential oil, so it is not fragrance-free.
Paraben-free preservative
Phenoxyethanol with ethylhexylglycerin keeps the water-based serum stable after opening.
What to expect over 12 weeks
Skin changes slowly, so it helps to know what each stage usually brings. Words from customers who reviewed this serum mark the way.
-
Day 1
Take a starting photo
Photograph your face and neck in daylight, from the front and the side, before the first drops. Repeat the same photos every four weeks: gradual changes are easier to judge side by side than in a mirror.
“The consistency and feel of this product with great ingredients is amazing.” Joanne C.
-
Weeks 1 to 4
How it feels first
Apply it once a day, or every other day while your skin gets used to it. Some people first notice how their skin feels: softer and more hydrated. Changes in how it looks usually take longer.
“This serum helped my Skin feel smooth and soft.” Mendy L.
-
Weeks 5 to 8
Early visible changes, for some
With steady use, skin may start to look smoother and more even, and some people describe a healthy glow. Compare with your Day 1 photos rather than the mirror, and keep going if you see no change yet.
“My skin is brighter and smoother, very hydrating product.” Heidi W.
-
Weeks 9 to 12
Time to assess
This is when most people judge a copper peptide serum. Take new photos in the same light and compare them with Day 1. Fine lines may look softer and skin firmer, and results vary with age, sun exposure and routine. One bottle lasts about 60 days, so 12 weeks takes about two bottles.
“I’m finishing up my second vial and can truly tell a difference.” John B.
Quotes are from verified customer reviews of this serum and describe individual experiences, not a clinical study. Results vary. This is a cosmetic product.
A few drops, morning or evening
Start once a day. When your skin is used to it, you can apply it morning and evening.
01 · Clean skin
02 · A few dropsPat it into the face and neck
Put a few drops on your fingertips and pat them over your face and neck until they disappear. Let it dry before the next layer.
03 · FinishSPF by day, moisturizer at night
In the morning, follow with sunscreen. In the evening, follow with your moisturizer or our GHK-Cu face cream.
If it pills or shows blue
Too much serum can roll up under makeup or sunscreen and leave a faint blue film. Use fewer drops, pat rather than rub, and let it dry fully before the next layer.
Reactive skin
It contains lemon peel oil and lemon essential oil. Patch test on your inner arm for 24 hours, start every other day, keep it away from your eyes and stop if irritation lasts.
With retinol, acids or vitamin C
Use strong actives in the other routine, for example this serum in the morning and retinol at night. If you use 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.

Questions we hear most often
Give it 8 to 12 weeks of daily use. Skin may feel softer and more hydrated first; changes in texture, fine lines or firmness take longer to judge. Results vary.
Pure GHK-Cu is blue because of its copper. At 1,200 mcg per bottle it is spread through the whole serum, so the serum itself has only a light tint. If your serum looks cloudy or has separated, contact us with the lot number on the bottle.
About 60 days of daily use, depending on how many drops you use. Subscribe and Save takes 20% off every bottle.
The Advanced serum is a separate formula with 1,200 mg of GHK-Cu, in a lockable pump bottle, and it costs more. This one holds 1,200 mcg of GHK-Cu in an amber glass dropper bottle. Compare them.
No. No cosmetic serum removes wrinkles. Used daily alongside sunscreen, it may help fine lines look softer over time.
No. It contains lemon peel oil and lemon essential oil, and customers often mention its pleasant scent. There are no parabens.
Yes. It is made for the face and neck, and the same thin layer works on the upper chest. Patch test a new area first.
Microneedling breaks the skin barrier, so follow your professional's advice or the device instructions. Many people wait until the skin has settled before applying any serum.
