Abstract

Aberrations of sebaceous follicles usually cause great mental suffering and unconfidence to the patients. A new time-dependent mathematical model was built up to investigate the photo-thermal interactions during laser sebaceous gland treatment. With this model, effects of treatment-affecting parameters, such as diameter and depth of the sebaceous gland, laser energy density, pulse repetition, and especially cooling methods, were numerically investigated. The simulated results showed that skin cooling is essentially necessary for achieving ideal therapeutical outcomes in laser sebaceous gland treatment, and CSC is the most effective cooling method. A simple but valid method to improve the therapeutical outcomes of laser sebaceous gland treatment, named as adaptive temperature control (ATC), was proposed. The results and conclusions are useful for optimizing laser sebaceous gland treatments and for designing new treatment procedures.
