Acne is a disease that is prone to recurrence and fluctuates in its own severity. There are many factors that affect acne, and it is often difficult to receive good results with a single treatment, so a comprehensive treatment is needed according to the condition. First of all, we should adjust our mindset and maintain a positive and optimistic state; eat less spicy and oily foods and sweets, which can stimulate oil production and aggravate acne; eat more vegetables and fruits, and keep the bowels open is also important. In addition, according to the skin type, choose the right facial cleanser and moisturizer, and develop good washing and care habits. Do not excessively remove oil without protection, resulting in overly dry skin and impaired skin barrier function, which will also aggravate acne to some extent. Insist on topical medication when symptoms are mild and add oral medication for control when symptoms are severe to shorten the natural course of acne and reduce the likelihood of its after-effects (acne marks and scars).
