Rhinophyma is a part of rosacea (a common skin condition, especially among people of Celtic descent), that is significantly more common among men. It affects the nose, causing thickening of skin and dilated pores. The skin around the nose thickens due to an excess production of oil from the sebaceous glands (oil glands). Even though this is not a life-threatening condition, the appearance of it can personally affect those who have it.
