"I recommend Mastara to all my patients because it signals to actually thicken the dermis on the skin rather than strip it. It’s exactly what’s worked for my patients to restore structural density without the irritation of harsh acids."
How Does It Work
How Does It Work
After menopause, your skin might feel thinner, drier, and more prone to wrinkles, sagging, and irritation. That, combined with dryness caused by hormonal changes, can cause sagging -- especially around the neck, jawline, and cheeks -- and fine lines and wrinkles. The lines and wrinkles you get with menopause are often crow's feet and lines above the upper lip. Lower estrogen levels can lead to lower levels of collagen, a protein that helps keep your skin plump and firm. Less collagen can cause your skin to feel thin and droopy. GHK-Cu doesn't just sit on the surface; it activates SIRT1, the "Cellular Reset Gene." This biological trigger forces your skin to behave younger, rebuilding lost collagen from the inside out to create a firmer, more structured, and more refined surface. Watch your skin reclaim its density. Fade deep lines, firm sagging areas, and bring back the plump, lifted look you had years ago. It’s not just skincare; it’s a return to the most confident, beautiful version of yourself.

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.
