Rosacea is a chronic inflammatory skin disease that causes persistent redness and possible lesions over areas of the face, including the nose, forehead, and cheeks. There are several misconceptions about rosacea and it can often be mistaken for acne, eczema, or an allergy. This skin disease generally occurs in patients between the ages of 25 and 50 years old. However, it is much more common in women and those with fair complexions. Although, women are more likely to have rosacea, the disease is generally thought to be more severe in men. Certain lifestyle triggers tend to bring on rosacea flare-ups; however, the exact cause of the disease is unknown. Dermatologists usually prescribe a regimen of more than one product to successfully treat rosacea.
