HINT: What are we doing? Applying makeup the OLD way? We used to apply the makeup, and then pack on the powder to keep it matte and keep it on. What can happen is that your skin starts to sweat from the feel of it. Anything that you ‘feel’ on the skin, your skin will try to ‘sweat’ off, or get rid of. Normal thing for it to do, but not if you want it to stay on. That’s why you see an increase in mineral-oil free and lanolin-oil free products. They’re usually the culprit in the ‘feel’ of the product. You can actually feel the oil sitting on your face, thus, your face is shiny in a few hours.
