Acne-like bumps on the vulva can be caused by folliculitis, pseudohygroma, condyloma acuminatum, and so on. 1. Folliculitis: secondary bacterial infection of the vulvar follicles can cause red bumps on the follicles, often accompanied by pain and other symptoms. 2. Pseudo condyloma: the cause is unknown and may be related to localized infection, irritation, improper cleaning and other factors, which can cause granular reddish pimples on the female pubic area. 3. Condyloma acuminatum: a sexually transmitted disease caused by human papillomavirus infection, which may lead to the appearance of cauliflower-like papillae in the genital area. There may be other reasons for acne-like bumps on the vulva, so you should go to the hospital in time and follow the doctor’s instructions for treatment.
