I'm curious about home care products for back acne (acne).

It's fall, the season when cool breezes bring us to long-sleeved clothes. It's a season we hide under outerwear, but the friction of clothes on our backs makes our acne worse and more irritating, weighing heavily on our hearts.
Unlike facial acne, back acne is difficult to manage.
I am concerned that inflammatory skin problems on my back, if not properly managed, could turn into pigmentation or scars.

In the dry and cool autumn season, I'm curious about home care methods that can manage both acne and skin troubles.
Could you recommend an ointment or body product (ingredient) that is available at Maypure and is effective in treating acne?
Fall is a season where a balance between moisturizing and exfoliating is crucial. What's a specific shower and moisturizing routine that can help manage pigmentation (scars) without aggravating acne?
Could you please recommend some effective 'treatment' home care products?
