Application Protocol for Research Use Standard application of a GHK-Cu topical serum in research settings follows a straightforward five-step protocol: Cleanse wash the target area with a gentle cleanser and pat dry Apply dispense a thin layer of serum onto the skin Absorb allow 23 minutes for full absorption before applying moisturizer or sunscreen Frequency apply once or twice daily for consistent research protocols Duration the published clinical studies used 12-week protocols to demonstrate measurable outcomes Researchers investigating combination approaches sometimes layer topical GHK-Cu with other cosmetic actives or research peptides

Wound Healing, Skin Repair, and Regeneration Research A multicenter, randomized, evaluator-blinded, placebo-controlled study in diabetic neuropathic ulcers reported greater median plantar-ulcer closure with topical glycyl-L-histidyl-L-lysine copper gel compared with vehicle, 98.5% versus 60.8%, and lower ulcer infection incidence, 7% versus 34% [3]
With age or factors such as poor diet, strenuous exercise, being overweight and certain health conditions, the amount of glutathione in our body decreases
[16] These remain areas of investigation in humans and should not be interpreted as established risks at this stage
