Intense Pulsed Light (IPL) is a popular device-based treatment for managing the diffuse redness and flushing associated with rosacea. While it is not as effective as vascular laser it can be a good option for those with lighter skin types and is often less expensive than vascular laser. It has higher risks than vascular laser in pigmented skin types and I would favour vascular laser in this context.
Unlike a laser, which delivers a single wavelength of light, IPL devices use a high-powered flashlamp to deliver a spectrum of light containing multiple wavelengths simultaneously.
This light passes through the surface of the skin and is aborbed by haemoglobin insmall blood vessels causing heating which causes them to collapse and seal shut. Because IPL spreads its energy over a broader area and covers a wider spectrum, it is less effective at destroying larger blood vessels but can be very effective at treating diffuse redness in those with lighter skin types.
A secondary benefit of the broad-spectrum approach is that IPL simultaneously breaks down excess melanin. This means it can treat sun damage, age spots, and freckles providing a comprehensive "photorejuvenation" effect.
Usually a series of 3-6 sessions, spaced by 4-6 weeks apart is required. The procedure is quick, with the flashlamp feeling like a rubber band snapping against the skin. Post-treatment downtime is consists of mild redness and a feeling similar to a mild sunburn that fades within 24 to 48 hours. It is essential that patients strictly avoid sun exposure for at leat a month before and after treatment to reduce the risk of complications.
