Rosacea is a skin condition characterized by redness, blotchy patches, flushed skin and inflammation. With rosacea, your skin is often sore, reactive to environmental factors, and is sensitive. It primarily affects the cheeks, nose, forehead, and chin but can also extend to the chest area. Rosacea begins with slight redness or blushing and can often progress into persistent redness and inflamed skin. Rosacea flareups are often due to a combination of genetic and environmental factors, such as a comprised immune system, having fair or light skin, a family history of rosacea or excess exposure to sunlight.
