A REAL PROGRESS IN HAIR REMOVAL.

A LASER HAIR REMOVAL ASSOCIATED WITH A SKIN COOLER.

The lasers are beams of concentrated light which are absorbed by tissues according to their wavelength.

For that we use a laser alexandrite which has a wavelength of 750nm what enables him to be absorbed selectively by the color black or brown, i.e. the pigment (the melanin) which is strongly concentrated in the hair, but also to a lesser extent by the pigment contained in the skin.

Thus the best effectiveness will be obtained on a dark hair with a clear or not very matt skin. It is impossible to apply this type of laser to very dark or recently bronzed skins, under penalty of burns and depigmentation.

Thus all the difficulty in order to improve the performance of a hair removal, is in the fact that the skin contains also pigment in more or less amount and when the power of the laser is increased, in order to obtain a better effectiveness, burns can appear or a very unpleasant burning feeling.

This is the principal reason of a certain number of failures of this technique, because in order to avoid burn and pains, the doctor operator reduces the power of the laser, thus decreasing the effectiveness of the treatment.

Applications of a cooled gel is often proposed, but they are often insufficient to maintain a temperature sufficiently low of the skin.

The solution at this problem is thus brought by our laser which is coupled with a cooler which projects air at -60°. This make possible to decrease the temperature of the surface of skin, where the pigment is, while letting act it more in the depth of the skin, where the hair follicle is.
We can then apply higher energy at the skin, without risk of burn or depigmentation, and pain.

The conclusion of our experience, is that the association of an air cooler with a laser for hair removal, allows the use of stronger energy, which improves the effectiveness of hair removal as well as comfort during the meeting.
