I want to thank you for your products are the best!  I've been 
using them for more than two years now; since he had a lot of
acne and sun spots; I started with the salicylic and the TCA 15%,
and I went up a few months ago to the 30% TCA and I was happy with
the results my spots faded almost completely and it is the first time
I see my skin so soft, even and radiant also use in mandelic cleanser and toner
every day.Thank you!
