Generally, the scab will fall off naturally within 3-7 days, and some will take longer depending on the individual’s physical condition and the external environment. In any case, you cannot pick the scab with your hands, it will infect the epidermis and in serious cases, pigmentation may not fade away. You can use medical skin care products, such as Winona and Yaxal for post-operative repair. You cannot get wet for a period of time, and you can use the repair gel to promote the improvement of the skin.
