What are the principles of laser hair removal
The laser of laser hair removal does not really hit the hair follicle, but the hair on the surface of the skin, causing the temperature of that hair to rise, and the heat energy will be transmitted to the whole hair. If the hair itself is in the “growth period”, the heat can be transmitted to the hair follicle smoothly, resulting in the apoptosis of hair follicle and successful hair removal.
Laser hair removal is not perfect, because it is most suitable for people with light skin color and deep hair. The treatment scope is locked in “dark pigment”. If your skin color is deep, the laser will destroy the skin pigment and cause white spots or black spots, which often takes several months to recover gradually. Doctors with rich experience in laser operation should be selected before laser hair removal; Careful maintenance and strict sunscreen should be carried out after operation.
