This is how I do my TCA peel:
I use Retin-A (0.025 creme) every day (start with every other day until you're used to the Retin-A. I apply copper serum first and then apply the retin-A) for 4-6 weeks, then stop 1 week prior to the peel (do not use AHA/BHAs either).
I do a 12.5% (start with 8%) TCA peel, 1 layer.
2 hours post-peel, apply Copper Serum (just a few drops) by [link removed]
do not use any AHA/BHA/retin-a products until skin is completely healed (1-2 weeks), then repeat.
My skin looks gorgeous now!~ I get my TCA peel from original skin care. I get the 25% and dilute it to 8% or 12.5%. I get my copper serum from [link removed]. I get my retin-a from canada ([link removed]) with a prescription from my doc.
