My back acne is not necessarily super severe, but it is not mild. A lot of it is scars, but I do have pimples too. I've been using baking soda on my back for a month and a half now, and i know my back isnt going to be cleared perfectly but i dont really notice a difference. For a while i would put lemon juice in it, but i stopped. Should i keep using it? Ive been trying to get rid of these scars for a while and they wont go away. What should i do?
