    Did Accutane twice. Worked both times, came back both times. I was so over starting from scratch. Three months on the GHK-Cu capsules and the thing that gets me isn't that I'm clear — it's that my skin doesn't lose it the week before my period anymore. Not perfect. But I'm not crying at the mirror at 7am either.

    Everyone's got something to clear your acne. Nobody's got anything for what it leaves behind. My breakouts calmed down last year but my forehead still looked like a map. Started the copper peptide capsules in March — around week 10 a coworker asked what I was doing differently. That's when I knew.

    My skin reacts to everything. Every active I've tried made it worse before better and I just don't have it in me anymore. Curvana's the first thing I've added that didn't punish me for it. Two capsules with breakfast, done. Three products in my routine now instead of nine.

    My cheeks were the worst of it — deep painful ones that never really went away, plus all the marks left over from the last round. Less redness by week 3 on the GHK-Cu. By week 6 my cheeks were calmer than they've been since high school, and the dark spots kept fading after that. Only thing I'd change is I tore through the first bottle and had to reorder. Rookie mistake.

HORMONAL ACNE

Your skin is not dirty. It ran out of signal.

Hormonal breakouts do not start on the surface. They start in the dermis, under the layer any cream can reach - which is why washing harder has never fixed the ones along your jaw.

GHK-Cu is the message your body sends to calm that layer and rebuild it. Taken as a capsule, it travels there through the bloodstream instead of sitting on top of the skin.

Nothing hormonal, nothing that makes you purge first. We put the message back.

  • Copper bisglycinate - the GHK-Cu carrier
  • Zinc and vitamin C for skin that keeps breaking out
  • Collagen peptides to rebuild what breakouts leave behind

How it works

  1. Work beneath the surface

    Zinc, DIM and myo-inositol work from the inside, reaching the layer topical creams were never able to influence.

  2. Support clearer-looking skin

    Zinc supports normal skin balance while DIM and myo-inositol support the hormonal balance behind skin that keeps breaking out.

  3. Feed skin renewal

    GHK-Cu is the copper peptide your fibroblasts use to rebuild collagen, carried to the dermis through the bloodstream.

  4. Soften the look of post-acne marks

    As the dermis rebuilds itself, post-acne marks may appear lighter, texture looks softer and the overall tone can seem more even.

How it works

THE SCIENCE

Why it works

GHK-Cu was isolated from human plasma in 1973. Fifty years of research explain what it does, and why your body makes less of it every year.

    GHK levels in human plasma fall from around 200 ng/ml at age 20 to around 80 ng/ml at age 60 - a decline of roughly 60%.

Questions, answered

When will I see a difference?

Most customers notice a change in texture between weeks 4 and 8. Skin renewal is slow by nature - consistency matters more than dose.

Can I take it with my skincare routine?

Yes. GHK-Cu taken orally works alongside topical products, it does not replace them.

How do I take it?

Two capsules a day with a glass of water, ideally in the morning.

Who should not take it?

Not suitable if you are pregnant, breastfeeding, under 18, or have a copper metabolism disorder such as Wilson's disease. Speak to your doctor if unsure.

How does the 60-day guarantee work?

Take it daily for 60 days. If you see no change, email us and we refund you in full.
