I have been using the microdelivery peel for about 10 years and LOVE it! I am almost 55 years old and have no sun spots or discoloration on my face, despite being a sun worshipper in my younger days. I only use it once a week, but love the way it makes my face soft and supple.
I have tried this set as a sample before and loved the results, which made my face very face afterwards, but found it to be a bit too expensive. Finally bought it with discount and would say it's a worthwhile purchase.
