Rosacea and dermatitis are inflammatory skin diseases. Some of the symptoms are similar, and facial dermatitis can look a lot like rosacea, but there are some differences. Only facial inflammation is involved in rosacea, and dermatitis can affect skin anywhere on the body. Rosacea can affect the blood vessels near the skin's surface, causing tiny red lines to appear, but dermatitis does not. Although rosacea and dermatitis can occur together, they are not related and require different treatments.
The most common symptoms of rosacea include flushed, pink skin; visible burning or stinging veins; red and enlarged nose; and small facial bumps that resemble acne pimples. An advanced case of rosacea can affect the eyes, causing burning, grittiness, dryness, and sensitivity to light. The cause of this skin condition is unknown, but heredity and the environment are thought to be factors. Outbreaks can occur due to stress, extreme temperatures, spicy foods, alcohol, sunlight, and some medications.
There are various types of dermatitis, and this skin disorder is also believed to be caused by genetic and environmental factors. One common type is contact dermatitis, which occurs when the skin comes into contact with a chemical to which the person is allergic. Poison ivy, poison oak, and poison sumac are the most common causes, but some other plants, metals, soaps, chlorine, and other substances can also cause contact dermatitis. Symptoms include a skin rash with raised bumps or blisters, and can also cause itching, pain, swelling, and tenderness.
Another type of dermatitis is seborrheic dermatitis, which is an inflammation of the sebaceous glands. This skin disease can appear on the eyebrows, on the forehead, inside the ear, on the scalp, and around the nose. When this disease occurs on a baby's scalp, it is called cradle cap.
The most common symptoms of seborrheic dermatitis are greasy or yellow patches of skin, scaly dandruff on the scalp, and scaly patches that sometimes have a burning or itchy sensation. The exact cause of this condition has not been determined, but experts believe that heredity and environment play a role. Breakouts can be caused by hormonal fluctuations, stress, and extreme temperatures.
A dermatologist will be able to diagnose and treat rosacea and dermatitis. Although there are no cures for rosacea and dermatitis, the symptoms can be controlled with medication. A person with these skin conditions can help prevent events by avoiding known triggers.
