Redness Is Not One Diagnosis. My Op-Ed on Why Rosacea Care Gets Oversimplified

Facial redness gets marketed and often treated as a single condition with a single solution: rosacea, treated with a laser. I think this collapses several distinct phenotypes into one label, and that collapse is where a lot of disappointing outcomes come from — not because the technology fails, but because it was aimed at the wrong target from the start.

The phenotypes hiding under one word

Persistent background erythema, visible dilated vessels, inflammatory papules and pustules, and thickened skin changes are recognized as distinct rosacea presentations that can occur separately or together, and each responds differently to treatment. A vascular laser targets visible vessels well and does very little for inflammatory bumps. Topical or oral anti-inflammatory therapy addresses papules and pustules and does very little for a persistently flushed background. Marketing a single device as "the rosacea treatment" flattens a condition that, in the dermatologic literature, is explicitly understood as heterogeneous.

Why the conflation persists commercially

A single confident answer sells a consultation more easily than a differential diagnosis does. "We treat rosacea with IPL" is a cleaner marketing line than "rosacea has several presentations and we need to determine which one you have before recommending anything," even though the second statement is the medically accurate one. I think this is a case where clarity of marketing and accuracy of medicine pull in opposite directions, and the industry has largely chosen marketing.

What I think a real consultation should look like

Before recommending any device, I want to know which phenotype is dominant, whether there are ocular symptoms that suggest a different management priority, whether the skin barrier is currently stable enough for procedural treatment, and what triggers the patient has already identified. That conversation takes longer than pointing at a laser. It also means some patients leave a first visit with a skincare and trigger-management plan and no procedure scheduled at all, which is not the outcome a device-focused business model is built to produce, but is, in my opinion, the correct one for a meaningful share of redness presentations.

If you are in Alpharetta or North Fulton and have been told your redness "is rosacea, we'll laser it," I would ask which phenotype they believe you have and why — not to be difficult, but because the answer tells you whether a real diagnostic process happened before the recommendation.
