How many shades lighter will it make u?

Never worked for me and gave me a bad rash.

Hard to talk about shades but so far about 3. There is a new gel out now though so I don't know how light that one will get you.

Of all the natural lighteners I have tried it is my favorite. I prefer the gel to the cream though they say the strength is the same but I have tried both and I think the gel works better.
