Precautions after photodynamic therapy for acne

1. Pay attention to the hygiene of personal cleaning products. Washing the face is a daily care procedure for everyone, and it plays an important role in keeping the skin clean. If the cleansing tools themselves are not clean enough, how can they be effective in cleansing the face? Not only will it fail to play the role of cleansing and skin care, it will also cause the affected area to be infected by bacteria and aggravate the symptoms of acne. Experts point out that facial cleansing tools should be disinfected regularly or replaced directly to provide a good space for the skin, which is conducive to the improvement of acne symptoms.

2. Pay attention to developing a regular schedule. The appearance of acne is also a warning from the body, reminding everyone that there may be some problems with the immune system, which gives acne an opportunity to take advantage. Experts remind everyone that adequate sleep is very important for good health, but many people often ignore this point. Staying up all night and reversing day and night are bad living habits that are the "accomplices" of acne. Therefore, everyone should arrange their work and rest schedules reasonably, combine work and rest, and ensure normal sleep, which is conducive to the prevention and treatment of acne.
