It’s pure, natural and the ingredient list is simple. If you sleep in it you won’t wake up with a face full of blemishes. In general, you should also check for skin sensitivity. I don’t suggest sleeping in the foundation or eye colors. Remember that the skin around the eyes is very delicate. However, in my opinion (this is just my preference), I prefer to go to bed with a clean face. I don’t want my minerals all over my pillow in the morning. I prefer to wash and moisturize my face before bed. Then in the morning, I mineralize my face. You can sleep in it but personally, I don’t want to. If you want to sleep in it that’s wonderful and I will be happy to provide you with all the minerals you need for daytime and night use.
