Rosacea is a widespread skin disorder that causes the affected individual to constantly appear red in the face. Though the condition is not a serious one, it can be traumatic for the afflicted because it involves the skin of the face and neck. Unfortunately, the root cause of rosacea is unknown and subsequently there is no actual cure. Treatments primarily focus on avoiding outbreaks and controlling symptoms. Epsom salts are an old-fashioned remedy that have been used for centuries to treat a variety of skin disorders, including some of the more common symptoms of rosacea, such as inflammation and redness.
