The hormone levels in your body are disturbed during pregnancy, which may indeed cause acne on your face. However, acne is not permanent and will gradually subside after the birth or when the body’s hormone levels gradually return to normal standards. For individuals who still have acne or pimples after the birth, it is recommended to use topical medications to improve the symptoms, such as topical adapalene gel or clindamycin gel to treat them. You should eat less sweets, spicy and stimulating food, avoid consuming too much greasy food, and ensure you get enough sleep, otherwise it will also cause acne to recur.
