looking to start an optimal skincare routine using topical retinoid (adapalene) and topical GHK-CU but I can’t figure out the best regimen,
I was thinking GHK in mornings and adapalene at night but I found out GHK can’t be applied at the same time as a mineral sunscreen (which I use every morning) because the zinc and copper compete for absorption
It also seems like based on my (limited) research that you shouldn’t mix topical copper peptides with topical retinoids (not sure what the reason is but I saw a few sources that said this)
Considering alternating each one every night but I feel like that’s suboptimal
Anyone have advice?
