Oh, good to know about the turkey neck! I've only been using GHK for a little over 2 weeks but already my facial skin is totally cleared up. I was getting breakouts daily for almost a year and could not find the culprit - nothing I changed in my skincare or makeup made a difference. But like magic, since I started the GHK, I've had zero breakouts for at a least a week now. I'm loving that, but I'm also hoping it's not the only benefit I'll get. I really want thicker skin, as odd as that sounds. I mean, when you reach certain age the term "crepey" starts to get thrown around. lol
And I'm happy to report that after the first week, there's been no ISR really. The first 4-5 days were big ol' red welts that itched a little, but also turned into bruises. Not a fan. But after that, I guess my body got used to the copper and stopped freaking out about it. I admit I do pin it right after my KPV in almost the same spot, and that likely helps. But, the end result is that it seems to be working and there's no spicy!! Win win!
