 We had a young man come in, he had psoriasis or eczema, one of the two, all over his knees. You know, his mom's been helping him with creams and antibiotics. And we just use, we have this other device, it's called X-Cryo, just like you saw with the mask. It's like a little portable air conditioner. You can give yourself a mini facial. I did that. It's really cheap. That's really cool.
