I keep my loofah by a window to prevent mold. I have been dry brushing before my showers about every 2-3 days but you can dry brush everyday if you would like. When I first tried it I noticed my skin shining as if I had just polished my skin. And that was before the shower. Also my skin felt tingly which was very interesting. When dry, the loofah feels coarse but not that rough either and my skin felt very smooth afterwards. I either use shea butter to moisturize or coconut oil and so far my skin is feeling and looking great. Not only is this great for the immune system but also helps with cellulite as well as stimulates the body to naturally detox. You can also use this loofah wet which I love to use on my elbows and feet. So far I will be adding this to my skincare regimen especially with the added health benefits.
