Rosacea, telangiectasia, and diffuse redness — treatment options explained.
Persistent facial redness typically results from permanently dilated or expanded blood vessels in the dermis — dilating beyond their normal range and failing to return to baseline. This is the mechanism of rosacea and telangiectasia.
Vascular lasers target oxyhaemoglobin — the compound in blood that absorbs specific wavelengths. The laser heats and coagulates the expanded vessel without damaging surrounding tissue. The body then reabsorbs the treated vessel over 1–4 weeks.
Rosacea is a chronic condition with both vascular and inflammatory components. Telangiectasia are individual dilated capillaries visible as red lines. Both respond well to vascular laser, but rosacea may require additional prescription management for its inflammatory component.
3–6 sessions for significant improvement. Maintenance sessions every 6–12 months are needed for long-term control.
Mild redness for 24–48 hours. Most patients return to normal activities immediately.
Laser manages rosacea very effectively but does not address the underlying genetic predisposition. Long-term maintenance is needed.
