I bought skin ID hoping it would improve my moderate acne. I started using the 3 products as directed, and in the first week i noticed that the small bumps on my forehead were slightly going away, and i wouldn't get more than a pimple on either side of my cheeks. But on the 5th day were i applied the BP i had a raised, puffy, red, itchy rash. So i stopped taking skin id all together, and it took 2 weeks, but my rash went away.
Skin ID started to work for me but then turned into a rash. I wouldn;t recommend this product for people with sensitive skin. Skin ID uses 3 kinds of acid, one acid in each of the 3 products you get. The directions are to use all of the products within 30 mins, so you're putting 3 harsh chemicals on your skin, one right after each other. So for sensitive skin its going to irritate very badly.
I know your looking for a solution for your acne, but if you have sensitive skin, i would advice that you don't use Skin ID. It will do more harm to your skin than good.
I would recommend going to your doctor instead and getting a prescription, and not ordering something from the TV.
Skin ID products aren't really designed for your skin. All they do is give you a different percentage of SA or BQ, but you're still getting the basic harsh chemicals found in all over the counter acne products.
