GHK-Cu topical serum: my 3‑month skin firmness experience

Posted by vo2max_sleep in Longevity & Anti-Aging - 1 points, 0 comments.

I started using a 1 mg/mL GHK‑Cu topical serum two times a day last summer. The product says it can help collagen synthesis and reduce inflammation, so I was curious if it would help my skin after the heavy training days I do. After about a week the skin on my face felt a little tighter but I did notice faint irritation on the cheeks – just mild redness, no itching.

I kept at it for eleven weeks, and by week eight the fine lines around my eyes ruedas less noticeable. My friends told me my skin looked more radiant. I also tried a small 200 µg injectable dose once a week for the last month, but I didn't feel much difference compared to the topical.

The serum is cheap, easy to apply, and I haven’t had any serious side effects. I’m still unsure if the changes are due to the peptide or just normal skin hydration, but for me it feels worth it. I’d love to hear if anyone else has seen similar results.
