A lot of little red pimple grew on the back what medicine to use

A lot of red pimples grow on the back, which may be eczema. If eczema, desonide cream or pevisone cream can be used for external application. At the same time, second-generation antihistamine drugs can be taken orally. Ebastine, loratadine, levocetirizine hydrochloride, etc. can be taken orally one pill a day. But if this kind of small pimple is not eczema, but this kind of acne or acne vulgaris, you need oral tanshinone capsules, local oral or topical fusidic acid cream, or topical adapalene gel or clindamycin gel. This can be done, while paying attention to local hygiene.
