I’ve purchased and compared competitor masks like Omnilux, Current Body, Numier and Silk’n to the Kala mask for an honest review, and I’m absolutely blown away by the superior quality of Kala. Unlike the others, Kala uses proper medical-grade silicone, which feels incredibly durable and comfortable. The LEDs are clinical-grade with higher irradiance (power), providing noticeably better results. On top of that, the battery life is significantly longer, making it much more convenient to use. Overall, Kala is a far superior product—worth every penny! Checkout the comparison photo
