The REALISTIC expectation is that not much improvement will be seen with ONE treatment. eMatrix is designed to have little downtime, with energy delivered in controlled Fractional doses. This treatment can improve skin tone, as well as acne scars and stimulate collagen production. Downtime can be predictable, and is based upon the density covered, and the power used. We always advice 3-5 treatments. For most Specialist we undertake the first treatment at a conservative setting, and increase the power and overlaps from there. Your end result will be best 2-3 months after your last RF treatment, and not the first. Hope this helpsDr Davin Lim Laser and skin, and aesthetic dermatologistBRISBANE, Australia
