Closed mouth acne on the chin can be taken care of on a daily basis. If the situation does not improve, you can also seek treatment from a skin specialist. You should wash your face correctly in your life, choose a cleanser that removes oil without irritation, and also avoid over-cleaning. Choose the right skin care products according to your actual situation. Keep enough sleep, avoid staying up late. Eat a light diet, avoid eating too much sweet and greasy food. Regulate your emotions, avoid too much mental stress, and avoid squeezing and scratching acne with your hands, so as not to cause the inflammatory reaction to spread and leave scars. In severe cases, an experienced medical professional should use a sterile acne needle to puncture the closed mouth of the acne follicle and gently squeeze it to expel stagnant keratin and sebum. Use medications that can help normalize the follicles, such as topical retinoids, to help eliminate acne. When acne appears on the face, it is important not to squeeze or blindly use medication on your own, lest you make the situation worse or get scars.
