Control oil by using a foaming or gel cleanser in the morning and at night. Follow with an alcohol-based toner or astringent.
Avoid using bar soaps and washing the face area more than twice daily as both will dry out the skin, which can cause irritation and may lead to acne.
If the skin is acne-prone, choose on exfoliator with salicylic or glycolic acid which helps open up clogged pores. In many cases of oily skin its recommended to use a mask with salicylic acid once a month.
Try an oil-free SPF 15 or 30 sunscreen instead of a moisturizer.
