For the bad odor which is common during puberty, you must wash once a day with warm water and soap, I highly recommend you to use Dettol Original Bar soap. When washing, pay attention MOSTLY to the hairy parts of your body such as your armpits and groin since they cause most of the sweat producing glands that give you bacteria quickly. For those horrible acne, pimples and pores, washing gently twice a day. Rinse of all the soap or cleanser with clean water and pat the skin dry with a dry clean towel. Make sure that the towels or/and the face cloths get laundered regularly so that they don't become a source of bacteria that causes infections. By doing this, you can keep your skin clean and healthy for days if you do this everyday!
Hope that this procedure helps! c:
