I just received my device today and I'm starting a 3-month test. I've also downloaded the Medicube app, which is an excellent guide for exploring the different modes. The Air Shot should be used once or twice a week for pore care, while Booster Mode for radiance, Derma-S for elasticity, and Line Volume mode for firmness care can be used up to three times a day. I use the device on clean skin with Medicube gel, and I'll share my results in 3 months.
