Myth #1: Acne is a normal developmental phenomenon in young people and does not require treatment. Most people believe that acne is a normal phenomenon during the developmental period of adolescents and that it will heal on its own after puberty and does not require treatment. However, there are various factors in modern life that cause acne to grow more often, especially on the face, which is recurring and growing. If left untreated, it will leave uneven scars. If you try to seek medical help at this time, you will miss the best time for treatment. Therefore, early treatment is necessary to avoid future problems. Myth 2: Acne is fine if you put some medicine on it, no need to take medicine. Most patients believe that acne is an epidermal disease, and that topical medication can be applied without the need for medication. It is true that sometimes topical medication can be effective, but it will continue to grow again after it subsides, treating the symptoms but not the root cause. This is especially true for hormonal medications, which can make skin quality worse after topical application. In order to completely treat acne, you still need to take internal medication together with external treatment, in order to treat both the symptoms and the root cause.
