It promotes cell migration, angiogenesis (new blood vessel formation), and helps reduce inflammation
Regular sessions may be needed to sustain the results

Here is an honest summary of what you can and cannot expect: What You CAN Realistically Expect Measurably softer, smoother skin texture within 34 weeks Visible reduction in fine lines, especially around the eyes, by weeks 48 Significantly firmer, more lifted-feeling skin by weeks 812 Reduced redness and improved skin tone uniformity from early weeks Improved healing of acne scarring, post-procedure recovery, and damaged skin A progressive, compounding improvement that continues building over months Hair thickness improvements with consistent scalp application over 812 weeks What You Should NOT Expect Dramatic wrinkle erasure in 12 weeks (those claims involve misleading photography or film-forming agents) Botox-equivalent muscle relaxation (GHK-Cu doesn't inhibit neurotransmitters that's Argireline/SNAP-8's role) Permanent results without ongoing use like all biological interventions, maintenance is required Identical results to someone else skin type, age, damage severity, and application consistency all affect outcomes GHK-Cu's results are directly proportional to consistency

In light of evidence from animal models that brain GSH concentrations peak in the morning, 46 the single study visit was scheduled at 0700 hours for each participant in an attempt to control for circadian fluctuations
The dramatic follicle enlargement seen in rodent models doesn't automatically translate to equivalent effects in humans with years of miniaturization already established
