Frequently Asked Questions

What is the difference between rosacea and acne?

They can look similar because both may produce bumps and pustules, but they are different conditions. Acne characteristically includes blackheads and whiteheads and often begins in adolescence, while rosacea centres on persistent facial redness and visible blood vessels and usually starts later in adult life.

Is rosacea the same as having a red face?

No. Ordinary blushing or a windburnt face is temporary. Rosacea is a recognised long-term condition in which the redness becomes persistent and is accompanied by other features such as visible vessels or bumps.

What is ocular rosacea?

It is the form in which the eyes and eyelids are affected as well as, or instead of, the skin, producing symptoms such as dryness, grittiness and irritation. It is diagnosed and managed by clinicians in the same way as the skin forms.
