Rosacea is a chronic condition that causes facial redness, visible blood vessels, and — in many people — inflamed bumps and pustules that can resemble acne. It most commonly affects the central face: the cheeks, nose, chin, and forehead.
Rosacea isn't fully understood, but it's thought to involve a combination of abnormal blood vessel reactivity, immune system dysregulation, and an overgrowth of Demodex mites that live naturally on everyone's skin. It tends to follow a relapsing-remitting course, with periods of flare-up followed by periods of relative calm, and it generally presents as one or a combination of the following subtypes:
Rosacea isn't caused by poor hygiene, and it isn't contagious. While the underlying cause remains an area of active research, flare-ups are commonly triggered by:
Triggers vary considerably from person to person, and identifying your own personal triggers is often a key part of long-term management.
Certain groups are more susceptible to developing rosacea:
We recommend seeking a dermatologist assessment if:
Rosacea is a chronic condition, and unlike a skin infection, it doesn't resolve on its own or run its course. Left untreated, it tends to persist and can gradually worsen over time, with flare-ups becoming more frequent and, in some cases, background redness becoming more permanent. Phymatous changes, once established, generally don't reverse without treatment.
The encouraging news is that rosacea responds well to appropriate management. While there's currently no cure, a combination of trigger avoidance, skincare adjustments, and medical or laser treatment can control symptoms effectively for most people, often achieving long periods of clear or near-clear skin.
Laser and light-based treatments — most commonly pulsed dye laser (PDL) and KTP and Nd:YAG lasers also used in some cases — target the visible blood vessels and background redness of rosacea by heating and closing off the affected vessels. They're a good fit for some rosacea presentations, but not all.
Laser therapy is generally worth considering if:
Laser therapy isn't usually the first step. It's most effective — and safest — once active inflammation (papules and pustules) is reasonably well controlled with medical treatment, and it doesn't address the tendency to flush or the triggers behind it, so it's typically used alongside, not instead of, ongoing trigger management and skincare.
