Why Did My Rosacea Suddenly Get Worse?

Rosacea is a condition known for its fluctuations, but a rapid and significant worsening of symptoms can be alarming.

What triggers rapid deterioration?

A sudden flare may be linked to a trigger. One of the most common causes is the introduction of a new skincare product that has irritated the skin barrier. Common culprits are retinols, retinoids or skin acids. Other causes include intense UV exposure (like a sunny holiday), a period of high stress, a change in weather (hot or cold extremes) or dietary triggers, such as a high intake of alcohol or spicy foods.

Could something else be driving the flare?

Yes. If your usual management strategies aren't working, consider other possibilities. A sudden worsening could also be due to the use of a topical or systemic steroid, which can cause steroid-induced rosacea. There could also be overlap with another condition like perioral dermatitis or seborrhoeic dermatitis. If your symptoms change dramatically or become unresponsive to treatment, a review with a dermatologist is very helpful.
