Real Transformations
Women over 40 reclaiming their skin during and after menopause.

"I'm not kidding when I say this serum changed everything. After menopause, my skin had collapsed. I've been using this for 4 months now and my husband literally asked if I got work done. The lines around my eyes are so much softer."
"I had acne scars for years and nothing helped. After a few weeks with this serum, the texture finally started to fade and my skin looks tighter and clearer. People even ask what I changed—I feel confident again."

Frequently Asked Questions
How long until I see results?
How long until I see results?
Most customers report visible improvement by Week 2-3. Dramatic transformation typically visible by Week 4-6. Everyone's skin is different, so results may vary by starting point. (Mechanism: SIRT1 activation timeline + gene reactivation speed)
Do I need a dermaroller or dermastamp for it to work?
Do I need a dermaroller or dermastamp for it to work?
No. GHK-Cu peptides work topically on their own. Some users prefer using a derma roller for enhanced absorption, but it’s completely optional.
Is it safe for sensitive skin?
Is it safe for sensitive skin?
Yes. GHK-Cu is bio-identical (your body recognizes it as self), so it doesn't trigger reactivity. It's specifically designed for
damaged/sensitive skin barriers. (Mechanism: Bio-identical formula + barrier repair benefits)
Can I use it with other products?
Can I use it with other products?
Absolutely. GHK-Cu works through SIRT1 activation (gene reactivation),
which works alongside other actives. Many customers use it with moisturizers,
serums, sunscreen. No known interactions.
(Note: May reduce need for other products over time as skin regenerates)
What if it doesn't work for me?
What if it doesn't work for me?
We offer a 30-day money-back guarantee. If you don't see results, full refund, no questions asked. That's how confident we are in our products. 85% of our customers saw a dramatic change.
Is this better than Retinol or other serums for anti-aging?
Is this better than Retinol or other serums for anti-aging?
It’s the opposite. Retinol exfoliates(strips) the skin; GHK-Cu signals the skin to rebuild. It triggers your body to thicken the dermis and restore structural density without the redness or peeling. It’s not just surfacing; it’s remodeling.
