When people complain of oily skin, they are most often referring to the skin on their face.
Oily skin is also the largest contibuter towards acne.
This page will give a little information on the causes and treatments of oily skin and acne. The oil is produced by oil glands known as sebaceous glands. These glands are bigger and more active in the region of the nose than any other areas of the face. This is why the nose tends to be a trouble area for even those with normal skin. The pores in this area are also larger, in order to accomodate the large flow of oil produced.
