Once I was introduced to a microderm-abrasion I was given samples of IS-Clinical of active serum, pro-heal and hydra-cool serum. These products did wonders for my skin. I have oily skin and prone to acne. The products kept my skin clear and glowing. I learned to appreciate my oily skin since that keeps me from wrinkling early(LOL). I wouldn't recommend to people who have dry skin or sensitive skin. I have been using the products for over 5 years. I'M LOVIN IT!!!!!
