Don't squeeze acne with your hands, don't use greasy cosmetics, don't use topical ointment, don't use steroid hormone topical ointment such as Skin Hydroxide Pine, Skin Lotion, En Skin Cream, etc., which will cause steroid agonistic acne, and don't use bromine and iodine drugs, which will cause wart-like papules, and proliferative acne.
To eat less fat and sugary foods, less fried foods and onions, garlic, chili and other stimulating foods, eat more fruits and vegetables, to prevent constipation and indigestion, which will help reduce acne.
Additionally, you should work and rest on time and try not to stay up late; wash your face diligently and clean your skin thoroughly!
