The newest lasers emit a beam of energy which is absorbed by the roots of growing hairs, injuring these follicles. This is far more efficient and less painful than electrolysis, where each individual hair has to be treated with an electric needle. This treatment is effective on the bikini area, underarms, upper lip, chin, chest, back and legs. Several treatment sessions are needed to achieve long lasting results.

Advantages
Much faster, simpler, more effective and less painful than electrolysis.

Disadvantages
White hairs are without pigment and do not respond very well. Dark, African-American type skin can be very tricky to treat as pigment in the skin can absorb the laser energy beam.
