How it works
The laser emits light at a wavelength absorbed by the pigment in the hair. The energy turns into heat and reaches the follicle, damaging it so that it no longer produces a new hair. Only hairs in the active growth phase respond, which is why several sessions are needed.
The result is a significant, long-lasting reduction in hair. Some finer hairs may grow back over time, and occasional maintenance sessions may be needed.
Who it suits
Laser hair removal works best on dark hair. Very light, blonde, red or white hair responds poorly. Skin and hair type are assessed before the first session, and the settings are adjusted to each person.
It is also useful medically, in hirsutism (excess hair growth in women, sometimes linked to hormonal imbalances that should be investigated), in folliculitis and ingrown hairs after shaving, and for hair in sensitive areas.
How many sessions you need
Usually 6–8 sessions or more, 4–8 weeks apart depending on the area (less often on the body, more often on the face). Between sessions you can shave, but do not wax or pluck.
Preparation and aftercare
- no sun exposure, sunbeds or self-tanner for 3–4 weeks before and after;
- shave the area the day before;
- after the session: mild redness that fades within hours; moisturiser and sun protection.
Contraindications
- pregnancy;
- recently tanned skin;
- photosensitising medication;
- active herpes or infection in the treatment area;
- some skin conditions, photosensitive epilepsy and other situations discussed at the consultation.
Risks
Temporary redness and swelling, irritation and, rarely, temporary pigment changes or small superficial burns.
Results vary from one patient to another.
