Usually, the face is a little darker than the neck, the skin is oily in the T Zone and dark spots from acne on the cheeks. So I want to mix the cream that helps the skin to be white and bright. And can protect from sun and UV because you have to sit and work in front of the computer for a long time every day. I don't know how much SPF I have to use and because I haven't mixed my own cream yet. So I want the cream recipe.
whitening that protects the skin from UV rays and how to do it in detail and the necessary tools, thank you very much
