1. Rosacea could be caused by one or more factors.
Rosacea could be caused by genetic, environmental, vascular and inflammatory factors. Skin damage due to chronic exposure to ultraviolet radiation has a part.
2. Rosacea has a distinct presentation
Rosacea produces red spots and sometimes pus filled bulging patches known as pustules. Unlike acne, rosacea pustules are curved, dome shaped rather than cone shaped and pointed. Rosacea patients do not have blackheads, whiteheads or nodules.
Three most common types of rosacea are:
Erythematotelangiectatic rosacea, characterized by red patches
Rosacea dermatitis, characterized by scaling
Phymatous rosacea characterized by swelling
General characteristics of rosacea include:
Frequent blushing or flushing
A red face due to persistent redness and/or prominent blood vessels
Red papules and pustules on the nose, forehead, cheeks and chin
Dry and flaky facial skin
Aggravation by sun exposure and hot and spicy food or drink
Sensitive skin: burning and stinging, especially in reaction to make-up, sunscreens and other facial creams
Red, sore or gritty eyelid margins including papules and styes
Sore or tired eyes
Enlarged unshapely nose with prominent pores and fibrous thickening
Firm swelling of other facial areas including the eyelids
Persistent redness and swelling or solid swelling of the upper face
Persistent yellow-brown raised spots and nodules
3. Rosacea symptoms typically involves your skin's immune response
The skin's innate immune response plays a part in the symptoms. High concentrations of antimicrobial peptides such as cathelicidins have been observed in rosacea.
4. Rosacea treatment begins with prevention
Rosacea patients are advised to avoid substances that cause facial flushing including spicy foods, oil-based facial creams (used water-based creams instead), topical steroids that aggravate symptoms, sun exposure and more.
Treatment focuses on managing symptoms, and may include a combination of oral and topical medications. These are aimed at reducing inflammation and redness caused by the enlarged the blood vessels.
A consultation with our dermatologist will help decide optimal course of action for treatment and ongoing management.
