I am very easy to get sunburnt … I tried many home remedies .. like application. Grams of flour, lemon juice .. .. but the tan is soo deep, is not working … I would like to get back to my skin …. please recommend me something … I saw the application of glycolic acid and the Internet syclylic acid works best tanning … So if I want to buy those stores will be how to use them from the chemical …. and tell me how to concentrate, I'll use .. thanks
