Do I Really Have Rosacea?

Facial redness is a common concern, but not all redness is rosacea. Understanding the key differences between rosacea and other conditions like acne, allergies, or general sensitivity is the first step towards getting the right diagnosis and treatment.

How can I tell if redness is rosacea vs acne, allergies or sensitive skin?

While there can be overlap, key features help distinguish them. Rosacea is defined by persistent central facial redness, flushing, and often visible blood vessels (telangiectasias). Acne typically involves comedones (blackheads/whiteheads), which are not present in rosacea, a key point when distinguishing it from rosacea in younger people. Sensitive skin reacts to products but may not have the persistent background redness or prominent blood vessels.

You can see examples of the different conditions that can look similar to rosacea at the following link - Differential Diagnosis of Rosacea. Please note that some of these conditions are very rare. [.

What are the early signs that mean I should see a dermatologist?

You should consider seeing a dermatologist if you experience frequent, uncontrollable blushing or flushing that lasts for an extended period, persistent redness on your cheeks, nose, chin or forehead, or the development of small red bumps or pustules that do not clear. Any eye symptoms like grittiness, burning, or redness (potential ocular rosacea) also warrant a professional evaluation.
