The invention provides a light spot scanning device, a scanning method thereof, and a medical cosmetology device, belonging to the technical field of medical cosmetology, comprising a laser and a collimating lens and a reflector arranged in sequence along the optical path transmission direction of the laser. The reflector is also connected with a driving member, the laser beam emitted by the laser forms a linear light spot through the collimating lens, and the reflector is driven to continuously rotate according to a preset path through the driving member. A plurality of linear light spots formed by the continuous rotation are sequentially overlapped on the light exiting side of the reflector to form a scanning linear light spot. Each time the reflector rotates, a group of linear light spots is formed. After continuous rotation, multiple groups of sequentially overlapping linear light spots are formed on the light exiting side of the reflector, called scanning linear light spots. The adjacent linear light spots have overlapping regions, and the energy density of the overlapping regions is higher than the energy density of the original light spot, which solves the problem of low energy density in the prior art. Moreover, the rotation of the reflector is used to superimpose the light spots without increasing the power of the laser, so that the light spot scanning device has a small structural size, low cost and high reliability.
