1. If you have oily skin, you should use an oil-free product

-FALSE! Oil needs oily products to break down the oil(tongue twister). Usually people with oily skin will use products that dry out their face, but instead of drying out the oil, it actually dehydrates the skin, which causes the face to produce more oil to make up for lack of water. So if you’re using a foaming cleanser, stop now. Foaming cleansers contain sodium lauryl sulfate which is what strips the water. I recommend switching to a cream cleanser, and I know if you have oily skin it might sound scary, but I promise within a week you’ll notice a change and you’re skin will be less oily.
