Detailed answer

First, wash your hands thoroughly to prevent any dirt or bacteria from entering the open pore. Clean the affected area gently with a mild cleanser. Afterward, apply a spot treatment containing benzoyl peroxide or salicylic acid to reduce inflammation and kill bacteria. Avoid touching or squeezing the area further to prevent infection and scarring. Maintain good skincare habits, including regular exfoliation and cleansing, to prevent future blackheads.
