Coming from experience, I can tell you having oily skin does not mean you can't use a beauty oil.
You might think, won't putting oil on oil just make my grease face look oil slick? Well I'm not going to lie to you, the first week your skin will go through an adjustment process. Since you will be adding oil to your skin, it will begin to balance out oil production. First it might seem like your skin is really oily, but after continued use the oil production will balance out and you skin will produce less oil because you are putting good oil in it.
