Frequently Asked Questions
Answers to the questions we get most. Ready to try it? Shop the GHK-Cu Copper Peptide Serum.
What is Good Measure?
An Australian copper peptide serum. Copper Tripeptide-1 (GHK-Cu) at 0.20% w/w (2.0 mg/mL), in a 30 mL airless pump.
What does it do?
Used nightly, skin looks firmer and fine lines look softer. It is a cosmetic, so we describe how skin looks and feels, not what happens underneath.
Who is it for?
People who want firmer-looking, smoother-looking skin, including anyone whose skin changed after a shift in body weight. It is a routine, not a rescue.
How do I use it?
Two pumps on clean, dry skin, morning or night. Keep it off the eye area. Moisturiser after. It absorbs in under a minute.
How long until I see anything?
Copper peptides are slow. Judge it over weeks of daily use, not days. Results vary and we do not promise a timeline we cannot keep.
What is the percentage, exactly?
0.20% w/w Copper Tripeptide-1 (2.0 mg/mL). It is on the label, and we publish a certificate for the product.
What else is in it?
Niacinamide, glycerin, panthenol, sodium hyaluronate, allantoin, Coenzyme Q10, tocopherol, and a light fragrance. Full list on the ingredients page.
Is it fragranced?
Yes, lightly. If you prefer fragrance-free skincare, that is worth knowing before you buy.
What should I not use it with?
Not in the same step as pure vitamin C (L-ascorbic acid), AHA or BHA exfoliants, or benzoyl peroxide. Use those at a different time of day.
Is it tested on animals?
No. The manufacturer's certificate of conformity states it is not tested on animals.
Do you sell injectable GHK-Cu?
No. We make a topical cosmetic only. We do not sell or advise on injectables.
Where do you ship?
Australia-wide, dispatched from Queensland, usually 3 to 7 business days with tracking.
