Laser Pigmentation Removal: When Does the Scab Fall Off?

　　Laser pigmentation removal works by using the instantaneous explosive energy generated by the laser to break up the melanin particles within the pigmented areas of the skin, promoting their metabolism and elimination, or directly ablating the epidermis of the pigmented area in a selective manner, thereby removing the pigmentation. The general reference price for laser pigmentation removal is 2000–6000 yuan per session, and visible improvement is usually observed within 1–2 weeks. The time required for scabs to fall off after laser pigmentation removal varies from person to person, but generally takes 7–14 days. Specifically, the scabbing period after laser pigmentation removal typically lasts 7–14 days. If the skin's metabolic rate is faster, scabs usually fall off within about 7 days; however, if the skin's metabolism is slower, it may take approximately 14 days. Detailed explanations are as follows:

　　For skin with a fast metabolic rate, the basal layer cells divide and proliferate more rapidly, enabling quicker generation of new keratinocytes to replace damaged epidermal cells. This allows scabs to separate from the skin and shed more quickly, usually within about 7 days.

　　Conversely, for skin with a slower metabolic rate, the basal layer cells divide more slowly, resulting in insufficient generation of new cells to promptly replace the damaged cells. This prolongs the separation process of the scab from the skin, delaying the shedding time, which usually takes about 14 days.

　　After laser pigmentation removal, it is recommended to keep the skin clean and prevent infection, creating a favorable environment for skin metabolism.
