I'm so happy I bought this product. It has been 30 days since I started using this product and I had no irritation reactions to the product. I had a problem with pimples on the right side of my face for two months, after I started using this product along with the cleanser, toner, moisturizer and sunscreen, I saw results in two weeks. I would really recommend you purchase this product along with its matching products for the best results.
