I got this product for Christmas and my sister paid the price from Black Friday sale which was a bargain!! I have been using this product for the last 3 weeks not everyday but just after the first 2 uses I saw a difference in my skin. It was more glowy and bright. i use air shot mode, MC , and booster modes. I have been researching this device and using select skin care products for your needs and this device will boost the absorption of these products so becareful of harmful products, research them as they are being penetrated into skin. I am very happy with my gift and also am using the Medicube collagen mask with it on top of my other skin care and it’s amazing!!! 100/10.
