Skincare Routine Retinoid + GHK-CU

[neo28]

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?

why cant GHK be applied the same time as a mineral sunscreen

additionally why do topical ghk if you can just pin ghk and get the systemic benefits

i heard zinc in mineral sunscreens and the copper compete for absorption making the ghk useless

i don’t think it’s worth it to pin for skincare benefits when topical is shown to work
