So how oily is your skin? Get a little closer to identifying by looking at the T-zone. Although wrinkles aren’t as prominent in oily skin, regular deep cleansing is needed to maintain proper pores. The time of day is starts really shining dictates how oily it is. If by mid-morning your T-zone looks slick, it’s very oily. If it remains dry through the afternoon, it’s less oily than you might have thought.
