Hello, I have been using your products for a good 10 months now with very few issues. I use skin signals, gentle cleanser, TT tightener,emu oil and the lactic powder 10. I have started using Tretinoin 0.05%, I use this daily at night and the cp in the morning. I have had no reaction. My question is, seeing as Tretinoin (retin A) is an active exfoliator do I still need to use my lactic 10 powder? Thanks

Yes, use both. But you can use them on alternate days.

Hydroxy acids and retin A work differently. The hydroxys dissolve older skin and the retin A helps remodel skin - probably by irritating the skin but no one really knows how retin A works.
