It usually takes 3 to 5 weeks for the skin to recover from having fractional laser. However, due to individual differences, such as treatment area, personal constitution, etc., some people may need longer recovery time. Fractional laser is based on the photothermal principle of generating laser light, and then the laser is divided into a number of beams using a special instrument, which has the effect of removing scars and spots as well as tightening the skin and eliminating wrinkles. Normally, it takes 3~5 weeks for the skin to recover after fractional laser treatment. However, the recovery time varies depending on the individual’s condition. If the treatment area is large, the recovery time will be extended. If the care after laser treatment is not standardized, allergy, infection and other symptoms, the recovery time will also be extended. Therefore, it is not possible to generalize the time needed to restore the skin after having fractional laser. For people who need to use fractional laser to repair their skin, it is recommended to consult a specialist at a regular hospital to understand the relevant matters.
