Hi, Freak and Sea is one of the Bethkepsi grits in skin care. What it is, is argon gas in an electrode, and when the electrode touches your skin, it generates ozone, it's oxygen. And bacteria can't live in oxygen. So what it's doing is it's actually pushing oxygen below the layers of your skin, whereby essentially killing the bacteria. The further away from your skin, the devices, the deeper it goes. So I always recommend using it with goss. And you're going to want no more than a quarter inch thick. You can spark it, so it's kind of like tapping it to get it a little bit deeper. And then you can just kind of like go in a circular motion. What cystic acne does, as well as testulars, is it leaves behind what we call post-inflammatory hyperpigmentation, which is basically pigments that's left behind from an acne lesion or some kind of prominent of the skin. And if you can calm that inflammation, you can likely avoid having the post-inflammatory hyperpigmentation occur. They're super safe and really effective for home use. And I always encourage my clients to buy one and use them at home in between treatments. You can use it every day. It's safe. The main thing is you don't want to crank it up too high. It should never hurt. So you want to feel like maybe a three, four tingle in treating it at home in combination with serums and peels. So you're getting exfoliation. I use it all the time in my practice and clients are amazed at how quick the results are. And I always tell them you can have this at home. And they're shocked. When I explain to them how easy they are to use, how safe they are to use, and how inexpensive they are.
