Even if you are diligent with regular face washing, your skin can remain oily and deep acne cysts can continue to present on the skin. If this is a new problem for you, there may be a hormonal component that should be addressed (an increase in androgen hormone influence can increase the production of sebum, or oil, by the sebaceous glands of the skin.) I recommend visiting a dermatologist for a full evaluation. Your dermatologist will recommend the most appropriate treatment for your oily skin and will help to clear the deep acne cysts before they cause permanent scars.
