From your description, you may be having truncate acne or pityrosporum folliculitis. Truncal acne is a variant of acne pimples which predominantly occurs on the trunk. P. folliculitis is a yeast infection of the hair follicles. For acne, you will benefit from a topical preparation containing 2.5 to 5 benzoyl peroxide. For the latter condition, 2 ketoconazole lotion will help. Hope this helps you. Take care.
