<human>:  What is a good facial cleansing routine for people with oily skin?
<bot>: A good facial cleansing routine for people with oily skin is to first cleanse the skin twice a day with a gentle cleanser. After cleansing, use an astringent or toner to help dissolve any excess oil. Finally, use an oil-free moisturizer to give the skin balance and hydration. Be sure not to over-cleanse or scrub too harshly as this can strip the skin of its natural oils and leave it feeling dry and tight.
