What the research shows
Topical GHK-Cu has dermatology RCTs supporting effects on collagen, skin barrier, and post-procedure recovery. Reasonable mechanistic data for fibroblast and keratinocyte effects.
What's still experimental
Injectable use in humans is largely unproven. Hair-loss and systemic anti-aging claims need larger trials.
Anecdotal / community reports
Cosmetic skin and hair-thickness reports are widespread; topical formulations are widely available OTC.
Anecdotal reports are NOT scientific evidence. They reflect personal experience and may not generalize.

Questions for your clinician
- Topical vs injectable — what's the evidence delta for my goal?
- Are there interactions with other dermatologic treatments?
