What is the difference between rosacea and seborrheic dermatitis?
Short answer: Rosacea and seborrheic dermatitis are both chronic skin conditions, but they have different causes and affect different areas of the face.
Detailed answer
Rosacea is a chronic skin disorder that primarily affects the central part of the face, including the cheeks, nose, and forehead. It is characterized by persistent redness, flushing, visible blood vessels, and sometimes small red bumps or pimples. The exact cause of rosacea is unknown, but it is believed to be a combination of genetic and environmental factors.
On the other hand, seborrheic dermatitis is a common chronic inflammatory skin condition that primarily affects areas rich in sebaceous glands, such as the scalp, face, and upper chest. It is characterized by red, scaly patches, oily or greasy skin, and itchiness. Seborrheic dermatitis is believed to be caused by an overgrowth of yeast on the skin, along with genetic and environmental factors.
In summary, while both rosacea and seborrheic dermatitis are chronic skin conditions that can cause redness and inflammation, they differ in the areas of the face they affect and their specific causes.
