Summarize:

If you have long hair, pull all of your hair away from your face and secure it with a hair tie. If you have bangs, you may need a headband to hold them back away from your face as well. After you've opened your pores, gently wash your face with your usual facial cleanser. You don't need to scrub hard, you just want to have a nice clean face to exfoliate. Wash off all the exfoliating paste with warm, not hot, water. Then splash your face with cold water to close your pores. Make sure you've removed all of the scrub, otherwise your face will be sticky or grainy from the leftover scrub. If you have oily, tough skin, you may be able to exfoliate daily without any problem. On the other hand, those with sensitive or dry skin should limit at-home exfoliating to 1-2 times per week. If your skin becomes red or irritated, cut back on how much you're exfoliating and consult your doctor.
Pull your hair back. Use the face wash you usually use. Rinse the scrub off of your face with lukewarm water. Time your treatments.
