Café-au-lait spots, also known as milk café-au-lait spots, are usually removed by physical therapy, including laser treatment and liquid nitrogen freezing. The cause of multiple café-au-lait spots is unknown and may be related to genetic factors. Multiple café-au-lait spots are largely related to neurofibromatosis type I. They will appear locally as flat, even hyperpigmented spots, which may increase in size with age, and are mostly found on the face and trunk, and are generally treated with physical therapy. You can choose tuned Q laser, intense pulsed light and other treatments, using the high energy of the laser to destroy and vaporize the pigment particles, which can effectively reduce and remove the coffee spots. Cryotherapy can also be chosen, using liquid nitrogen freezing to destroy the diseased tissues to achieve the effect of lightening and eliminating coffee spots. For patients with multiple coffee spots, it is recommended to go to regular hospitals for consultation and examination, and under the guidance of doctors for treatment.
