Hi, My name is Arushi and I'm 22. Recently, i have been getting some pimples on my chin, around the jawline and they actually take a lot of time, about a week to heal. Some even left a small black mark. I'm doing everything for avoiding them; not taking oily foods, taking proper sleep and diet, keeping my face clean and everything. Please tell me what to do? is there anything I must include in my diet or any lotion or antiseptic that can wor?
