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.
The novel method of non-ablative FP is acknowledged as an effective technique by offering significant clinical
improvement while minimal risk of complications. A new time-dependent mathematical model was built up to
investigate the photo-thermal interactions during FP treatments. With this model, effects of treatment-affecting
parameters, such as diameter, density and energy of the micro laser beam as well as skin cooling, were numerically
investigated. Different photo-thermal behaviors with various treatment parameters were particularly discussed, based on
which, a novel concept of programmable treatment procedure (PTP) was proposed. With this technique, desired
therapeutic outcomes may be obtained from personalized treatments.
