RASHES & ROSACEA
Rash is a generalized, non-medical term that refers to irritation of the skin. A wide variety of conditions from eczema to viral skin eruptions to poison ivy can develop rashes. It is important to have rashes correctly diagnosed by a dermatologist in order to determine appropriate treatment.
Rosacea is a common skin condition, usually occurring on the central face. It is typically characterized by facial flushing worsened by exercise, extreme temperatures, emotional stress, and hot or spicy food or beverages. There are four subtypes: erythemato telangiectatic (redness and broken blood vessels), papulo pustular (acne-like bumps), phymatous (thickening of the skin and excessive growth of oil glands), and ocular rosacea (redness and irritation of the eyes).
The cause of rosacea is unknown but blood vessel changes, underlying skin inflammation, skin mites (Demodex), and even iron metabolism may contribute to the condition. Genetics play a role—individuals of Northern European ancestry are more likely to develop the condition. Sunblock, topical prescription medications, oral doxycycline, laser treatment, and Intense Pulsed Light treatment all may help control rosacea. Avoidance of aggravating factors is also important to avoid flares
