A variety of factors can contribute to combination skin, but more often than not, it just comes down to the luck of the draw in terms of what you inherited from your parents. However, the types of skincare products you’re using can absolutely make it worse or even cause the problem. Read on to learn what you might unknowingly be doing to contribute to making combination skin more of an issue. As you might already have suspected, using products that contain harsh or skin-aggravating ingredients will inevitably dry out some areas of your face while stimulating oil production in other parts (especially around the nose) that were already oily. If you’re using the wrong products, you might actually be causing your combination skin. If you use the right products, you may still have some amount of oily skin, but at least you won’t have dry, rough skin underneath excess oil. Once you start using the right products, your skin can improve almost immediately, with the dry areas softened and smoothed and the oily areas less oily and red—plus minimized pores.
