Rosacea is a very common skin condition. It is known to cause redness in the skin and it causes blood vessels to appear more visibly across the face. It sometimes manifests as red bumps or pustules.
The symptoms and signs of rosacea may appear on the skin for weeks to months, and can diminish as well within a similar timeframe. Rosacea is often mistaken for either acne, some other skin condition or an allergic reaction.
