A friend of mine who sells Melaleuca recommended that I try Melaleuca Zap-It for my daughter. My daughter is 14 years old and has been having a problem with acne. I liked the idea of the Melaleuca being a "natural" product. I liked the idea of not putting chemicals on her face. Well the good news is that it worked pretty well at clearing up her acne. The bad news is that after about a month she started to have extremely dry skin. She told me that her skin actually hurt and that it burned when she was using the products. She does have sensitive skin so we did try to cut it back a little to see if maybe she was just using too much for her skin type but she continued to have the dry skin. We did stop it completely and then waited for her skin to go back to normal. After her skin was better she did want to try it again and used one quarter of the recommended amount and she had the same reaction. I am happy to say that when I returned it Melaleuca did give me a complete refund. I think that Melaleuca is a good company but this product just did not work for my daughter although it may work for other people with less sensitive skin. Effectiveness It did help with her acne. Ease of Application Very easy to put on. Convenience Easy to use bottle - ready at any time. Side Effects Really dried my daughter's skin out - had to quit using it. - I will say this though - Melaluca did give an immediate refund when I told them the problems we were having so even though the product did not work they are a very ethical company. Immediacy Cleared up acne ok but the drying out was awful.
