You can spend $300 on serums and your skin can still look tired.
Most of what bothers you at 40 isn’t aging. It’s inflammation.
When estrogen drops in your 30s and 40s, your skin’s alarm cells start firing more easily. You feel it before you see it. Less filter for redness. More itch. Skin that reacts to things it didn’t used to. A glow that just isn’t there anymore.
A serum can’t fix that. The signal your skin is missing is a peptide your body used to make.
GHK-Cu is a tiny copper-bound peptide. Your skin made plenty of it at 25. By 40, levels have dropped meaningfully. Prescribed clinically, it tells your skin to stop reacting and start repairing. The first wins are what patients stop feeling. The visible changes come a few weeks later.
There are two real ways to take it. A stable prescription cream for daily skin barrier support. A small shot under the skin when you want a whole-body effect. We often stack it with BPC-157 and TB-500. That’s our Glow Stack.
A serum is not a plan. A plan looks at your skin, your hormones, and your labs together.
How we do it at Protocol Health:
Physician-led. Every plan is written by a licensed clinician.
Family-owned. The people writing your plan are the same people on the phone when something feels off.
Personalized. Starts with your skin, your hormones, and your labs.
