"I have been suffering from moderate acne for many years. I bought Gel serum along with Liquid Spray. The products did not irritate my skin at all. I applied the products before going to sleep. In the morning, I notice that the acne became dry and the inflammation is reduced. After using for a few days, my blemishes were greatly reduced. It also helped me get rid of new blemishes effectively in a couple of days. This is totally incredible. "
