Quick answer: The Vbeam is a pulsed dye laser that targets haemoglobin, the pigment in blood, so it works on redness that comes from blood vessels. That makes it a good fit for persistent facial redness, visible broken capillaries and red or raised scars. It reduces redness rather than curing rosacea, so most people need a course of treatments.
How does a pulse dye laser work?
A pulse dye laser (PDL) delivers a 595nm wavelength of yellow light in very short pulses. Haemoglobin absorbs that light, so the energy heats the targeted blood vessel rather than the skin around it. The vessel wall collapses, and the body gradually clears it away over the following weeks. A burst of cooling spray fires just before each pulse to protect the skin’s surface.
We use the Vbeam Perfecta at our Harley Street clinic. Treatments are carried out by GMC-registered doctors and specialist-trained laser practitioners, and the clinic is regulated by the Care Quality Commission (CQC).
Can Vbeam treat rosacea?
Rosacea is a long-term skin condition that mainly affects the face. The NHS says it can’t be cured, but treatment from a GP can help control the symptoms. Laser is one option for the persistent redness and visible blood vessels that rosacea can cause. It doesn’t replace medical care for the small red bumps some people get, which are usually managed with treatments from a GP or dermatologist.
If you have rosacea, we first examine your skin and map the pattern of redness and vessels. A small test pulse may be used to check how your skin responds. Triggers such as alcohol, spicy food, heat and sun can still cause flare-ups after treatment, so laser works best alongside a trigger-aware routine and daily sun protection. You can read more on our page about Vbeam for rosacea and facial redness, and our guide to rosacea versus other causes of facial redness.
Can Vbeam treat scars?
New scars are often red or pink because healing brings extra blood flow and new vessels to the area. Because Vbeam targets those vessels, it can fade the colour and, over a course of sessions, help soften and flatten some raised scars. We use it for surgical scars, acne red marks and early hypertrophic scars. See our pages on Vbeam for red and raised scars and Vbeam for acne red marks.
It has limits. Older white or silvery scars have few blood vessels left, so they respond far less. Indented acne scars need other approaches. Keloid scars can behave unpredictably, so we assess them with our keloid specialists and plan treatment around the whole picture, not laser alone. The NHS explains how keloid scars differ from other scars on its keloid scars page.
What can and can’t Vbeam help with?
| Concern | Is Vbeam suitable? | Notes |
|---|---|---|
| Persistent facial redness | Often | Works on the blood vessels behind the colour |
| Visible broken capillaries | Often | See also Vbeam for spider and thread veins |
| Rosacea bumps and pimples | Not on its own | Usually needs medical treatment from a GP or dermatologist |
| Red or pink surgical scar | Often | Best while the scar still has a blood supply |
| Raised (hypertrophic) scar | Sometimes | May be combined with other scar treatments |
| Acne red marks | Often | Treats the colour, not the texture |
| Old white or silvery scar | Rarely | Few vessels left for the laser to target |
| Keloid scar | Only within a specialist plan | Needs assessment first |
| Indented acne scars | No | Other treatments suit these better |
What happens during a Vbeam treatment?
- Consultation. The doctor or laser specialist examines your skin or scar and confirms Vbeam is suitable.
- Preparation. Your skin is cleansed, and numbing cream is optional.
- Test pulse. New patients may have a small test area treated first.
- Treatment. The laser is passed over the area, with a cooling spray before each pulse. Most sessions take 15 to 30 minutes.
- Aftercare. Cooling and written aftercare advice are given straight away.
How many sessions will I need, and when will I see results?
Sessions are usually repeated every 4 to 6 weeks. Many people start to see improvement from around 2 to 3 weeks for redness and 3 to 4 weeks for scars, with further change after each session. The number of sessions depends on the condition and how severe it is, so your doctor will set out a plan at your consultation. Because rosacea is a long-term condition, redness can return over time, and some people have occasional top-up sessions.
Downtime, side effects and aftercare
Downtime is usually 0 to 3 days, but bruise-like marks can last longer, so plan around social events.
| Effect | How common | Usual duration |
|---|---|---|
| Redness or warmth | Common | Several hours |
| Bruise-like marks (purpura) | Common | Typically fade within 3 to 10 days |
| Swelling, especially around the eyes or nose | Common | Usually settles within 24 to 72 hours |
| Temporary lightening or darkening of the skin | Uncommon | Usually resolves over weeks to months |
| Blistering, crusting or infection | Rare | Contact the clinic if you notice unusual pain, pus or worsening redness |
- Apply a broad-spectrum SPF 30 or higher every day for at least 4 weeks after treatment.
- Avoid direct sun and sunbeds for 2 to 4 weeks before and after treatment.
- Avoid hot showers, saunas, steam rooms and strenuous exercise for 24 to 48 hours.
- Pause retinoids and exfoliating acids for 5 to 7 days.
- Don’t pick or rub the area, and use a gentle, fragrance-free moisturiser.
When to see a GP first
See your GP if you have new or worsening facial redness, sore or gritty eyes or eyelids, or any scar or skin lesion that is changing. These need a medical diagnosis before cosmetic treatment. We’re also happy to arrange a GP consultation at the clinic.

Frequently asked questions
Does a pulse dye laser work for rosacea?
It can reduce the redness and visible blood vessels that come with rosacea, but it doesn’t cure the condition. Bumps and pimples usually need medical treatment as well. Your doctor will explain what to expect for your skin.
Can Vbeam treat red or raised scars?
Yes. Vbeam is used for red, pink and early raised scars, including surgical and acne scars. Older white scars respond far less, and keloids need specialist assessment first.
How many Vbeam sessions will I need?
It depends on the condition and how severe it is. Sessions are usually repeated every 4 to 6 weeks, and your doctor will set out a plan at your consultation.
Is there downtime after Vbeam?
Downtime is usually 0 to 3 days of redness. Bruise-like marks are common and typically fade within 3 to 10 days, and mild swelling usually settles within 24 to 72 hours.
Is Vbeam painful?
Most people feel brief stinging or warmth with each pulse. Numbing cream is optional, and a cooling spray protects the skin.
Can I have Vbeam if I’m tanned?
You should avoid direct sun and sunbeds for 2 to 4 weeks before treatment. Tell us about any recent sun exposure so we can advise on timing.
