Laser hair removal: body areas and protocols
Upper lip, underarms, bikini line, legs, back: each area has its own session length, pace and precautions. Guidelines for building your packages.
Why each area is different
Hair density, thickness, colour, skin sensitivity and regrowth rate vary from one area to another. These differences influence the settings, the duration and the number of sessions.
Indicative session lengths
According to the source: 5 to 10 minutes for the upper lip, 10 to 15 for the underarms, 20 to 30 for a classic bikini line, 30 to 45 for a full bikini, 30 to 40 for half legs, 45 to 60 for full legs or the full back. A full body takes several hours: it is better to spread the areas over several appointments.
Number of sessions and intervals
Most areas require 6 to 8 sessions spaced 4 to 6 weeks apart. The full bikini often requires more. Areas with slow regrowth (underarms, bikini line, back) can be spaced a little further apart.
Sensitive areas
The underarms and bikini line are more sensitive: SHR mode and good cooling improve comfort. On the full bikini, the proximity of the mucous membranes calls for great caution.
Fine or light hair
On fine, blonde or lightly pigmented hair (arms, nape of the neck, female back), effectiveness is lower and more sessions are needed. Red or white hair responds very poorly.
Face and dark skin
On the face, always carry out a test from skin type III upwards. On skin types IV to VI, reduce the energy, favour the appropriate wavelength and SHR mode, and space sessions further apart.
