Laser hair removal aims to destroy hair follicles by thermocoagulation using light energy. It allows progressive permanent hair removal from any area of the body and face. The principle is simple, the laser will focus on the melanin in the hair and heat to such a high temperature that the entire hair will disintegrate. This includes the destruction of the bulb, the hair shaft and all its components. Thus, the darker and thicker the hair, the lighter the skin; the better the result of the laser will be.
On average 5 to 10 sessions are necessary to permanently eliminate body hair, and 7 to 10 sessions for facial hair. All areas of the body can be treated with laser. The number of sessions to permanently eliminate hair can also vary from one person to another, depending on hormonal factors for example. It is essential to shave the area the day before your hair removal session EXCEPT on all areas of the face where the hair must remain as is.
PS: Do not confuse laser hair removal and pulsed light, which are two completely different techniques and whose results are not comparable.
The benefits of laser hair removal include:
- Precision: Lasers can selectively target dark, coarse hair while leaving the surrounding skin intact.
- Speed: Each laser pulse takes a fraction of a second and can treat multiple hairs at the same time. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, can take up to an hour.
- Predictability: Most patients experience permanent hair loss after an average of three to seven sessions.
