The invention discloses a medical cosmetology instrument with an efficient atomization mechanism, which belongs to the technical field of cosmetology instruments, and comprises a box body, an atomization mechanism is arranged in the inner cavity of the box body, a 
protection mechanism is arranged on one side of the box body, a fitting mechanism is sleeved in the inner cavity of the 
protection mechanism, and the atomization mechanism comprises a liquid 
medicine box; the liquid 
medicine box is fixedly connected to one side of an inner cavity of the box body, a refrigerating 
machine is arranged at the bottom of the liquid 
medicine box and communicated with the liquid medicine box through a condenser 
pipe, and a water pump is arranged in an inner cavity of the liquid medicine box. According tothe device, a 
filter element adsorbing impurities can be replaced conveniently, 
cold air can be introduced into the condensation 
pipe of the bottom refrigerating 
machine box, the 
cold air can be mixed with liquid medicine to reduce the temperature of the liquid medicine, the adjusting effect on the temperature of the liquid medicine is improved, impurities are filtered, the safety of a 
skin absorption medicated bath is improved, and 
anaphylactic reaction caused by the impurities is avoided; meanwhile, the liquid medicine is rapidly atomized through the 
ultrasonic atomizer, the 
absorption effect is improved, and the use requirement is met.
