Xiaomi beauty accessories

I purchased the Xiaomi InFace because I wanted to thoroughly exfoliate while washing my face. When I use it, my skin feels squeaky clean with absolutely no dead skin cells left behind. However, it feels a bit irritating to the skin, so I only use it about twice a week. At around 20,000 won, I wondered if the price was a bit high for a beauty accessory, but it is a product I really don't regret buying.
