Hello, I want to buy from China the raw material salycilic acid and do my own vitalize peel (chemical peel) .
What percentage should I get and how do I mix it and with what and the application instructions?

Chemical peels are not for amateurs and I for one would not do this to my face. May I suggest you use a loofa on your face instead to get rid of the dead skin? Chemical peels are risky even if done by a dermatologist as you have no idea just how your skin is going to react to that particular chemical.

I wouldn't recommend doing a salicylic acid peel. Concentration of salicylic acid greater than 2 percent will damage the skin and cause toxicity.

Try using an over-the-counter alpha hydroxy acid cream. This will help slough away the dead skin cells and improve your skin's clarity.

Salicylic acid PEEL of 20% will do the trick. It is made by Skin Laboratories. I bought in on AMazon, and it is great but use it regularly or the results can start to recede. Now Ihave been using it regularly with a hydroquinone cream of 3% (Othine) and it I really evening out my skin tone.
