Whether exfoliation is useful for acne needs to be judged in relation to the cause of acne. Acne growth is affected by many factors and may be related to abnormal keratinization of cells around the hair follicle, in which case proper exfoliation is useful in treating acne. Acne can also be related to bacterial infection, increased androgen levels, increased sebum production and other factors, and exfoliation is generally not useful for acne caused by this condition. Those with abnormal keratinization of cells around the hair follicles can be properly exfoliated to aid in the treatment of acne, but they should not blindly apply cosmetics on their own or go to beauty institutes for exfoliation treatments to avoid causing skin allergies or unnecessary damage. Attention should be paid to the application of drug treatment under the guidance of a professional doctor. Vitamin A acid drugs can be used to promote keratolytic metabolism and treat acne. If the symptoms are more serious, you can also take oral vitamin A acid drugs to relieve acne. For acne caused by other causes, other medications or treatments should be applied to treat the cause. If you have a bacterial infection that causes acne, you can take topical or oral antibiotics as prescribed by your doctor, and pay attention to keeping your facial skin clean; if your androgen level increases, you can take oral anti-androgen medication as prescribed by your doctor, but you should not take such medication for a long time; if your sebum secretion increases, you can take oral medication to reduce the secretion of oil.
