Analysis of illness: Hello, pearl rash is a normal physiological variation, which is harmless to the body and generally does not need treatment. Pearl rash mainly occurs at the junction of the edge of glans penis and coronary sulcus and/or at the frenum. The main manifestation is 1-3mm papules, which are located on both sides of the frenulum and have great damage. The top of the papule is round and smooth, and some papules are hairy or filamentous. Most papules do not fuse with each other, and they are densely arranged in one or more rows, which are obvious on the back of the glans penis and can partially or completely surround the glans penis. The color is mostly pearly white, a few are reddish, and some may be slightly red and swollen. No tenderness, no ulceration, and generally no discomfort.

Suggestions: But sometimes pearl rash is the cause of premature ejaculation. You can go to the hospital to get rid of it with laser, or you can use pearl powder for treatment. Usually, you must keep your genitals clean and dry, and wear loose and breathable cotton underwear. Eat less spicy food.
