Understanding underarm laser hair reduction
Underarm hair is usually coarse and dark, which makes it one of the better responding areas. The skin here is also prone to friction-related darkening, which often improves once shaving and waxing reduce.
Deodorant, recent waxing and any active irritation are checked before treatment, because treating inflamed skin increases the risk of pigmentation.
Underarms are commonly combined with other areas in the same appointment, as the session itself is brief.
This may suit you if
- Frequent underarm shaving or waxing
- Ingrown hairs, folliculitis or razor irritation
- Darkening of the underarm from repeated hair removal
