According to the search results, there is no scientific evidence to suggest that laser hair removal causes cancer. Laser hair removal uses non-ionizing radiation in the form of a concentrated light source that produces a very fine laser beam, which is different from the ultraviolet (UV) wavelengths found in sunlight that are known to damage the DNA in cells and cause skin cancer. The lasers used for hair removal are specifically designed to target the pigment in hair follicles and do not produce harmful radiation that could cause cancer. However, some researchers have observed changes in atypical moles after laser hair removal, so they suggest caution in the use of cosmetic laser therapy for people with a personal or family history of skin cancer or atypical moles, until further research determines whether these changes may be malignant or not. In addition, laser hair removal can cause temporary side effects such as skin irritation and pigmentation changes, and rare side effects such as excessive hair growth in the area of treatment, changes to overall skin texture, and burns, especially if the treatment is performed by an inexperienced provider. Therefore, it is important to choose a board-certified dermatologist to perform laser treatments and to follow their instructions to reduce the risk of side effects. Overall, laser hair removal is considered a safe and effective method of hair removal by the FDA.
