There are several possibilities for the itching of small red dots on the face as follows: the first possibility is hormone dependent dermatitis, which is mainly caused by the long-term external use of glucocorticoid ointment. In addition to the itching of small red dots, small pustules, desquamation and capillary dilation can also occur. The treatment requires oral levocetirizine hydrochloride capsules, one capsule per night, combined with compound glycopyrrolate capsules 3 times/day, 2 capsules/time, topical vitamin E ointment applied 2 times/day, and also the application of pimecrolimus ointment, applied 2 times/day for treatment. The second may consider solar dermatitis, mainly due to allergies caused by sun exposure, which can be treated with oral loratadine capsules, one capsule every night, and topical zinc oxide ointment with borate. The third possibility is cosmetic dermatitis, which is treated in the same way as solar dermatitis, with attention to avoiding cosmetics during the treatment period.
