I’ve been injecting GHK-CU, and wanting to improve my skin for my face. One thing I struggle with is Blackheads on my face. What could I use to treat the blackheads, also I’ve been seeing a trend of Tretinoin on tik tok, I’m curious about it but i don’t want to endure the purging phase. Is there way to bypass the purging phase or is it not even worth using tretinoin?
