I've not tried this clinic before and have gotten my skin largely clear by going off gluten and watching dairy (specifically drinking milk) but I also discovered mandellic acid products at Makeup Artists choice and have been really pleased. They have a wash, toner, serum and peel specific to the MA line. I only use the serum and peel and really like them a lot. Good products and very affordable so for the people hesitant to pay the money for the clinic perhaps try the MA line from MUAC as a cheaper trial. They sell sample sizes, too.

Fwiw, I also have used and been impressed with other products outside their MA line. Their gly luronic serum is awesome, as are the lactic and glycolic peels.
