Oily skin occurs when the skin over-produces oil on a regular basis, leading to breakthrough shine or congestion. This 3-step system includes a full size cleanser, toner and moisturizer to target and remove oil without over-stripping your skin, and delivers the hydration needed to balance excess shine.  
How to tell if you have oily skin:
skin looks oily/shiny shortly after cleansing
visible/large pores on the t-zone + cheeks
many clogged pores + breakouts
