I'm seriously impressed with this product! After trying similar devices from other brands, the Silk'n EMS Mask really stands out thanks to its wide range of features. I especially appreciate the different LED light settings that let you focus on specific skin concerns, plus the added bonus of EMS. I've had some hormonal breakouts recently, and the blue LED light has definitely helped speed up healing and minimize scarring. The EMS function is a game changer too! My skin feels noticeably firmer since I started using it.
