Acne and rosacea are two different skin conditions. Acne is caused by over-producing oil glands that cause inflammation. Rosacea is a long-term skin condition that causes flushing and redness in the center of the face, bumpy skin texture, and sensitive skin. Rosacea can differ from acne in the lack of comedones (whiteheads and blackheads), and how rosacea usually involves the mid-portion of the face whereas acne can involve the entire head/neck and chest/back areas.
