Totally works! Reduced fine lines around my eyes & smile lines, healed my acne weeks! faster,leaving none of the red spots I used to get for weeks.Is reducing old scars I have from cystic acne & no new breakouts! Blackheads from TEENS almst all gone! The copper does stain the acne a lil as it heals, will have dry spot over blemish which may turn brownish as it heals underneath,once dry skin falls off, the blemish is almst totally healed & barely discolored.Can lift sum blemishes,heal fast tho I did a few peels before getting to the CP's. Used Retin-A for abt 6 wks, then 18% TCA, didn't seem do much, dried acne some, peeled a little (less than Retin A), didn't work better than 10% BP(tho I suspect I got a low quality product). 25% TCA on my back & chest took care of cystic acne tho, now I wash body with PanOxyl bar & spot treat if needed w/10% BP. 4 wks ltr did Jessner's Cross w/15% TCA(same session one after the other no rinsing til the end), 1 layer of each left on min. time.Helped a little more, peeled & cleared more spots. Never had gross "stay in the house" skin. Started using CP Serum & LacSal serum from Skin Biology, got samples of Tri-Reduction, loved it! Bought the Tri-Reduction, got samples of Emu Oil,loved that more! Few weeks after 1st one did Jessner's cross again, 3 layers,then 15% TCA(same session) 3 layers, left max time til I frosted some. Rinsed and used Emu oil to heal. Skin was raw and peeled some,still not as bad as Retin A. 10 of 10!I'm 30 w/17 yo skin!
