Laser hair removal is how to achieve the purpose of

Human skin is a relatively light structure, in a strong laser in front of the skin is simply a transparent cellophane, which laser can be very successfully through through the skin depth of the hair follicle (the site of hair growth), with a lot of melanin in the hair follicle, they are able to absorb a lot of first laser and eventually converted into heat energy, the hair follicle temperature to achieve the destruction of hair follicles function purposes.

in this process because of the relative skin does not absorb laser energy, or absorption of a small amount of laser energy, so the skin itself will not have any damage , and the other laser installed in the treatment of head cooling device to protect the skin, so hair removal treatment of the skin, while not injury occurs and, therefore, abnormal pigmentation or scarring does not occur and other reactions.

hair growth has three stages: growth phase, stationary phase and the catagen, and only when the hair follicle when the hair follicles in the growing season will have a large number of pigment granules exist in order to attract a large number of laser energy, so laser in the growth phase of hair removal with the role, retire Xingqi and resting hair pigment is relatively small, so laser The therapeutic effect relatively weak. For this part of the hair need to wait until they are slowly growing season only after the transition to laser removed, so laser hair removal Treatment can not be successful, often requires several consecutive laser exposure (two treatment intervals ranging from 3-6 weeks) will be able to achieve the desired results.
