There is nothing like cleansing your face at the end of the day - nothing! Although it's also important to cleanse in the morning, too, to wash away the impurities your skin releases overnight as you rest.
Choose a cleanser which best suits your skin type, and don't be afraid of oil cleansers - they are truly amazing! Follow with a toner for the most thorough cleanse.
