If such small granules have obvious bumps when touched by hand, accompanied by obvious itching and a red change in appearance, consider the possibility of simple perioral dermatitis, which is related to allergic irritation. It is recommended to choose to use oral cetirizine tablets, and then apply localized glyburide lotion or dehumidifying and antipruritic cream, which will soon make the small granules subside. If the small granules growing underneath have obvious hyperkeratosis with no obvious self-conscious symptoms, it is considered possible that it is idiosyncratic hyperkeratosis of the follicular opening, and you can choose to use topical compound lactic acid cream with adapalene gel for treatment, which has obvious improvement efficacy.
