The perfect OPT (Optimal Pulse Technology) core technology, using the concept of three-dimensional technology: energy + pulse width + pulse waveform. The energy of each pulse acts on our skin without attenuation, and it is precise because this also forms a perfect pulse energy, eliminating the high energy peak of the E-light and IPL first pulse, and the sub-pulse energy decays one by one. A technical drawback, this makes OPT a particularly significant improvement in the efficacy of treatment, especially in the treatment of ecchymoses, hair loss, and skin rejuvenation.
