If you haven’t been living under a rock for the past ten years then you’ve probably heard of laser hair removal – but how exactly does it work?
Laser is an acronym for light amplification by stimulated emission of radiation. During laser hair removal a beam of light is guided over the skin. The light energy is absorbed by areas of high pigment/ melanin e.g) hairs, where it transfers as heat energy. The heat energy heats the hair and in the process damages the follicle, the follicle is then unable to grow new hairs.
At Skin HQ we use the award-winning Cynosure apogee elite laser. The cynosure laser uses two laser systems – a 755nm alexandrite laser and a high powered 1064 nm Nd: YAG laser, this allows us to target different hair colours and skin types. Cynosure’s apogee elite laser targets hair follicles which are currently active or growing. It’s important to understand the three phases of hair growth:
- Anagen – At this stage, the bottom of the hair follicle is attached to the dermis and its blood supply through the dermal papilla
- Catagen – The hair follicle begins to die and enters the catagen phase
- Telegon – The remains of the hair bulb are inactive and the attached hair easily falls out
Laser hair removal actively targets the first phase of hair growth (anagen). By targeting this phase the hair is destroyed permanently and offers permanent hair reduction. Multiple sessions are needed as hair grows at different rates, therefore, it is imperative to repeat the process to catch the hair at anagen phase.
