So you want to know how to stop oily skin. Planning a skin care routine around your oily skin type is essential, the more you understand how your skin behaves and reacts, the easier it will become to take care of it. Firstly, if your skin is overproducing oil, you need to wash your face. Try washing in the morning and at night. You might be tempted to wash your face more frequently, but over-washing can actually cause your skin to produce even more oil. If you do decide to wash more frequently, observe how your skin reacts and take note of how much is too much. Next step is moisturizing with a lightweight moisturizer. If you find your skin is particularly susceptible producing oil, try moisturizing only at night instead of also including the morning. Make sure to fully remove your makeup at night before going to bed, as clogged pores can contribute to excess oil.
