Oily and combination complexion types are prone to a variety of imperfections due to excessive levels of sebum, the natural oil that keeps the skin pliable and supple. With too much oil on the complexion, the skin often becomes shiny. Sebum deposits can also attract bacteria, causing blemishes and breakouts. In addition, when sebum mixes with dirt and dead skin cells, it forms clogs and plugs that stretch the pores and make them visible to the naked eye. The NUXE Aroma-Perfection collection was designed with oily and combination skin types in mind to offer solutions to all of these common problems.
