Not only are the products wonderful but the customer service is OUTSTANDING!! I purchased a skin care system for rosacea. After trial and error I discovered the support serum was burning my skin. It turns out I have an intolerance to tea tree oil which is in the serum. I emailed customer support to tell them I cant use the serum and I asked if there was a product I could use in its place. They got back to me right away and told me to dispose of the serum and they sent me a jar of AVT cream which I love!! My skin is looking so much better since starting the skin care system (minus support serum) It is also soft and smooth (I am in my early 60s). I will continue to be a customer on Zenmed!
