A randomized clinical trial evaluating GHK-Cu skin care products after CO2 laser skin resurfacing (a procedure causing deliberate controlled skin injury for anti-aging). Patients using GHK-Cu showed reduced post-treatment redness and improved wrinkle and skin appearance outcomes at 12 weeks compared to controls, supporting GHK-Cu's clinical utility in post-procedure wound healing.
