I too think you're maintaining your "hygiene maybe in excess."
Too much showering dries the skin excessivly. Try once a day, or every two days. Lay off the body wash, try a gentle soap. Use warm, not hot, water to shower.
It's NORMAL to have acne during puberty.
All medicines have side effects and that includes whatever is in the body wash and the salicylic acid.
Give your body some time to recover from all the showering/acid. Take a break for a week or so and see what happens.
Hope it helps.
