There will be different degrees of reactions 24-72 hours after photorejuvenation, such as local redness, swelling, pain, and in severe cases, exudation of tissue fluid. If the wounds are inflamed or there is blood oozing out, you should not wipe or apply medication by yourself. No special treatment is needed for minor bleeding, but serious bleeding requires prompt medical attention. As the wound scabs, the area will become dry and itchy, but cream products should not be applied as they may prolong the healing time of the wound with emulsifiers. Candidates should use water-based products such as sprays, moisturizing water or other moisturizing products for sensitive skin whenever possible. Moisturize more often each day and apply at the first sign of dryness and itching, but scratching with the hands is prohibited. In addition, one week after the treatment, the most important thing is to cleanse and deep moisturize. Candidates can choose a deep-cleansing cream moisturizing mask that can moisten the dead skin and make it fall off naturally during the cleaning process, but never pull on the wound or squeeze the scab. During this period, use a paper tear-off moisturizing mask to greatly reduce the discomfort on the face. Also, the skin is sensitive during the photorejuvenation treatment period, so pay particular attention to sun protection and try not to go out during the hottest and sunniest hours.
