Laser for Rosacea and Thread Veins in London 2026. Pulsed Dye or Intense Pulsed Light, and What a Doctor Chooses
Last updated September 2026. Written for The Wellness, Marylebone. Every clinical figure below carries its source.
Pulsed dye laser and intense pulsed light both reduce facial redness and visible vessels, and the trials find no clear winner between them. Chang pooled four studies covering 141 participants in 2021 and found no statistically significant difference between the two for achieving more than half clearance of facial erythema of rosacea, and Zhai and colleagues reached the same conclusion in 2024. So the choice is made on your skin type, your diagnosis and which vessels are actually visible, not on which machine a clinic bought. London pricing runs from about £115 a session for a small vascular area to £600 for both eye areas.
Take the free laser suitability check and a doctor will tell you within one working day which of the two is likely to suit you.
Why the platform argument is the wrong argument
Search for rosacea laser in London and you will find clinics arguing for their platform. Some will tell you pulsed dye is the gold standard for vascular work. Others will tell you intense pulsed light covers more ground per pass and treats background redness better. Both arguments have something in them, and the trials do not settle it.
Chang's 2021 systematic review and meta analysis in the Journal of Dermatological Treatment pooled four studies covering 141 participants and found no statistically significant difference between pulsed dye laser and intense pulsed light in achieving more than fifty percent clearance. Zhai and colleagues, in a 2024 meta analysis in the Journal of Cosmetic Dermatology, came to the same place. The pooled trial numbers in this field are small, which is worth knowing, but the direction is consistent and it is not the direction the marketing suggests.
What that means practically is liberating. If two reasonable options perform comparably, the interesting question moves from which machine to which problem, and that question a doctor can actually answer by looking at your face.
How both of them work
Both target oxyhaemoglobin, the pigment in red blood cells. Light at the right wavelength is absorbed preferentially by the blood inside a vessel, heats it, and damages the vessel wall so the body clears it. The surrounding skin is largely spared because it absorbs far less at that wavelength.
Pulsed dye laser at 585 or 595nm delivers a single wavelength tuned close to a haemoglobin absorption peak, which makes it precise and effective on discrete vessels. Intense pulsed light is not a laser at all, strictly speaking, but a filtered broadband light source, and that breadth is both its weakness and its strength. It is less precise per vessel and covers a wider field, which suits diffuse background redness. For larger, deeper thread veins, a longer wavelength such as Nd:YAG at 1064nm reaches further and is often the right tool.
What a doctor actually chooses on
Which vessels are visible. Discrete telangiectasia running across the cheek or beside the nose is a different target from a general flush across the mid-face. The first favours a precise, vessel-directed approach. The second favours a broader field. Many people have both, which means a plan rather than a single setting.
Your skin type. Intense pulsed light is absorbed by melanin as well as haemoglobin, which raises the risk of pigment change in darker skin and rules it out at some skin types. Pulsed dye is less affected but not exempt. This is the single biggest safety input and it is why skin type is recorded before anything else.
The actual diagnosis. Not all facial redness is rosacea. Seborrhoeic dermatitis, lupus, contact dermatitis, photodamage and flushing from other causes all look red. Treating a vascular laser at an inflammatory dermatosis wastes your money and can inflame it. Some patients need a topical or oral treatment for the inflammatory component before, or instead of, any light-based treatment. This is where a doctor earns the fee.
Whether you are on anything photosensitising. Some medicines make skin far more sensitive to light and change the plan or the timing.

What to expect, and the honest limit
Rosacea is a chronic relapsing condition. Vascular treatment reduces the vessels and the background redness you can see, and it does not change the underlying tendency. So maintenance is part of the plan rather than a sign that something went wrong, and a clinic that presents a course of three as the end of the matter is not describing the condition accurately.
A typical shape is a course of three sessions spaced four to six weeks apart, then a review, then maintenance at intervals that depend on how quickly your redness returns. Some people need one session a year. Some need two or three.
Flushing and blushing, the neurovascular part of rosacea, respond less well than fixed vessels and background redness do. Papules and pustules are the inflammatory part and are treated medically, not with light. Being clear about which of those three you mind most is the fastest way to a plan that satisfies you.
Downtime and risk
Pulsed dye laser at purpuric settings can leave bruising that lasts a week to ten days, and at non-purpuric settings usually leaves redness and mild swelling for a day or two. Intense pulsed light usually means redness and a warm, sunburnt feeling for a few hours to a day, sometimes small crusts on treated vessels. Around the eyes, protective shields are used and swelling is more noticeable.
Risks include pigment change, more likely in darker skin and with intense pulsed light, blistering, and rarely scarring. Sun exposure before treatment raises the risk of pigment change, so treatment is deferred if you are tanned.
What it costs in London
sk:n lists thread vein and vascular treatment at £115 for a fifteen-minute session, or £103.50 a session in a course of three. London Premier Laser lists intense pulsed light for rosacea and rejuvenation from about £126 to £154 a session. The Skin to Love Clinic starts Regenlite from £250 for a full area, with individual lesions averaging £75.

At The Wellness, redness and pigmentation programmes start from £950 for one area in a single session, £2,250 for the full face across a course of three with a doctor review, and £4,250 for face and neck across a full course treating vessels and pigment together where the examination shows both. The consultation is credited against whichever you go on to have.
Frequently asked questions
Is pulsed dye laser or IPL better for rosacea? Neither, on the current evidence. Chang pooled four studies covering 141 participants in 2021 and found no statistically significant difference between them for achieving more than half clearance of facial erythema, and Zhai and colleagues agreed in 2024. The choice is made on your skin type, your diagnosis and which vessels are visible.
Will laser get rid of my rosacea? No. Rosacea is a chronic relapsing condition and vascular laser reduces the vessels and background redness you can see rather than changing the underlying tendency. Maintenance is part of the plan. The inflammatory papules and pustules are treated medically rather than with light.
How many sessions will I need? A course of three spaced four to six weeks apart is the usual starting shape, then a review, then maintenance at intervals that depend on how quickly your redness returns. That varies a great deal between people.
Can I have vascular laser on darker skin? With care, and the platform choice changes. Intense pulsed light is absorbed by melanin as well as by blood, which raises the risk of pigment change in darker skin and rules it out at some skin types. A vessel-directed laser is often the safer choice. Skin type is recorded at the assessment and drives the decision.
Does it bruise? Pulsed dye laser at purpuric settings can leave bruising for a week to ten days. At non-purpuric settings, and with intense pulsed light, expect redness and warmth for a few hours to a day or two instead.
What if my redness is not rosacea? That is a real possibility and a good reason to be examined first. Seborrhoeic dermatitis, lupus, contact dermatitis and photodamage all present as facial redness, and a vascular laser aimed at an inflammatory dermatosis wastes money and can inflame it. If that is what a doctor finds, you are told, and the assessment fee is credited against the treatment you actually need.
