Ablative Lasers
Ablative Lasers
Ablative lasers target water as the main chromophore in the sebaceous gland, thereby halting sebum production. Four studies have evaluated the use of the 1,540-nm Erbium glass laser, a mid-infrared laser resulting in 73% acne reduction after a 2-year followup. No significant side effects were associated with the use of this laser.40
Another study evaluated a diode laser (1,450 nm) used in combination with cryogen spray cooling to target the sebaceous glands. The cooling effect of the cryogen protects the epidermis from thermal damage, allowing the heat to only affect the sebaceous
glands. A reduction of acne lesions after a single session has been reported, with side effects ranging from transient erythema to edema.41 Though several studies have reported that the 1,450-nm diode laser is effective for treating inflammatory lesions, it may be less than ideal in practice given the significant pain associated with its use.30
