Anyone using topical GHK-CU for stretch marks?

Hello everyone, I wanted to talk skincare and the title question. For anyone applying GHK-Cu on the skin, what problem were you targeting and what changed for you? I began reading about it and came across claims that it does little before 40 and mostly helps with redness, which puts me off a bit.

What I'm after is something for stretch marks, plus moisture for my hands. Over the past year they've gotten weirdly dry no matter how much hand cream I use, and I drink more than two liters of water a day. I also have those little keratosis pilaris bumps on my legs. My old routine was very simple and worked well, but I dropped it during a move and never picked it back up. I do like glutathione IV sessions but needles at home are not for me, too squeamish. Would GHK-Cu make sense for any of this, and how did you apply it and when did the first change show up?

Copper peptide and vitamin C in the same routine can irritate, so I keep GHK-Cu for night and vitamin C for the morning. Patch test it on your inner arm first, and don't start it the same week as a retinoid.

Making a lotion out of it instead of the usual serum is worth exploring, I remember someone writing a really good guide on that which I need to revisit. Ive tried microneedling but I dont know much, so Ill wait for others. Skincare always begins with sunscreen for me, so which one do you use? My favourite is a K-Beauty one, a watery light SPF 50, just heavenly. K-Beauty shopping is tempting, but for standard topicals like toner, serum, emollients and lotions the savings arent much bigger than shops like Amazon or Sephora. Injecting fillers myself is out of the question. Im vain, and the face is anatomically complicated with very little room for error, so between vanity and common sense I stay far away.

I use a GHK-Cu cream for dry patches and redness, not the injectable. It took me six to eight weeks to see anything, and the effect was mild: a more even tone and less flaking. I wouldn't expect it to do much for older stretch marks.

For stretch marks the thing with the best reputation is still a retinoid on fairly new red or purple ones, plus patience. Old white ones rarely change with any cream. If you try GHK-Cu on them anyway, use it at night after cleansing and give it a full three months before judging.

A year of dry hands even with lots of water usually isn't about hydration. I'd look at soap and hand washing, and put a thick ointment on right after each wash. Same for the bumps on your legs: keratosis pilaris tends to respond to a lotion with lactic acid or urea, no peptides needed.

Thanks for sharing your results with ghk-cu. I've noticed some loose skin around my neck and face lately and have been thinking about giving it a try to firm things up a bit.
