Diode Lasers in Cosmetic Dermatology

Hair Removal Treatments

In the field of cosmetic dermatology, diode lasers have emerged as formidable instruments for hair removal, renowned for their high efficacy. These sophisticated devices emit a wavelength of light that is selectively absorbed by the melanin in the hair follicles. The absorbed light energy is then transmuted into heat, effectively impairing the follicles and thus impeding future hair proliferation. This method, referred to as selective photothermolysis, is meticulously designed to target the hair follicles with precision, concurrently minimizing any collateral thermal damage to the surrounding epidermal tissue.

Hair undergoes various growth stages – anagen (active growth), catagen (transitional), and telogen (resting) – each exhibiting distinct responses to laser treatment. Diode lasers demonstrate a particular proficiency in treating hairs during the anagen phase, the period wherein the hair is in active growth and most vulnerable to the thermal effects of the laser. As a result, a series of treatment sessions, typically spaced several weeks apart, are requisite to effectively target as many hairs in their anagen phase as feasible.
