Red Light Therapy for Spider Veins: What It Can and Cannot Do
Red light therapy for spider veins does not close or remove the veins: dermatologists do that with a vascular laser, intense pulsed light (IPL) or sclerotherapy. Where red light fits is the skin around them, and small clinic studies found LED light eased facial redness gently and moderately. Below: the clinic treatments, the LED studies, flushing, timing, warning signs, prevention and device set-up.
Key takeaways
- LED red light does not close spider veins; dermatologists close visible vessels with a vascular laser that heats them until they collapse. Cleveland Clinic, 2025
- A Cochrane review of 35 trials with 3,632 people found no clear difference in improvement between laser and sclerotherapy for leg spider veins in the 5 studies that compared them. Nakano, Cochrane 2021
- In a small open study of 20 adults, combined 633 nm and 830 nm LED light moderately reduced camera-measured facial redness, and 7 of the 10 LED patients felt no pain. Naranjo García, 2023
- In a 2025 rosacea study of 90 patients, LED light helped redness and itching more than it helped visible blood vessels. Zhang and Song, 2025
- Sun damage is the most common cause of spider veins on the face, so daily sunscreen belongs in every plan. Cleveland Clinic, 2025
Can red light therapy for spider veins remove them?
No: LED red and near-infrared light does not close, shrink or remove a vein, whether it comes from a clinic lamp or a home mask or panel. Visible vessels are closed in a clinic, while red light is used for the redness, comfort and overall quality of the skin around them.
The clinic treatments work in a different way. Laser light is absorbed by the blood in the vessel, and the heat makes the vessel shrink and dissolve. ASDS Sclerotherapy uses an injected solution that "causes the walls of the vein to stick together". AAD, 2026
Home LED light is built for a different job. One of its most reproducible effects is "an overall reduction in inflammation", which is why it suits red, reactive or sun-damaged skin. Hamblin, 2017 Light also raises local blood flow for a short while, as our red light therapy for circulation article explains, but that brief rise is not vein closure.
What is the difference between spider veins and broken capillaries?
Both are telangiectasias: small, widened blood vessels just under the skin. "Broken capillaries" usually means fine red lines on the face, while "spider veins" often means red, blue or purple clusters on the legs.
Cleveland Clinic describes them as "damaged, visible blood vessels just beneath your skin's surface", made up of tiny capillaries, venules and arterioles rather than true veins. Cleveland Clinic, 2026 DermNet notes they are generally harmless. DermNet, 2025
- Face: sun damage is the most common cause; other causes and risk factors include rosacea, hormonal changes, pregnancy, liver disease, long-term steroid creams and smoking. Cleveland Clinic, 2025
- Legs: long periods of standing or sitting, family history, pregnancy, hormonal changes, older age and injury. AAD, 2026
On the legs, spider veins are usually cosmetic, but they can be an early sign of chronic venous insufficiency, where leg veins struggle to return blood to the heart. Cleveland Clinic, 2026
Which treatments close spider veins on the face and on the legs?
On the face, vascular lasers and IPL are the usual choice. On the legs, sclerotherapy is the most common treatment, with laser as an option and treatment inside the vein for larger varicose veins.
| Treatment | How it works | Used most for | What to expect |
|---|---|---|---|
| Vascular laser | Heat in the blood collapses the vessel | Facial broken capillaries | Three to four sessions every three to four months, then touch-ups |
| IPL | Filtered broad-band light that heats the vessels | Facial redness and vessels | Repeat sessions about a month apart |
| Sclerotherapy | An injected solution seals the vein | Leg spider veins | Usually 2 or 3 treatments; veins fade in 3 to 6 weeks |
| Endothermal ablation | Heat from a catheter placed inside the vein | Larger varicose veins | Done under local anaesthetic |
| Home LED red light | Low-level light on the skin surface | The skin around the vessels | Does not close vessels; aimed at redness and comfort |

The face and the legs respond differently. The ASDS calls laser or light therapy the "treatment of choice for facial spider veins" and says it is used only rarely on leg veins. ASDS Blue vessels, including most leg thread veins, are harder to treat with light and may suit sclerotherapy better. DermNet, 2024
For leg veins, the Cochrane review found laser and sclerotherapy gave similar improvement across 5 studies, with possibly less dark staining after laser. Nakano, Cochrane 2021
Can red light help the redness around broken capillaries on the cheeks and nose?
The closest evidence says it can ease background facial redness, moderately and gently, while the vessels themselves are left for a clinic.
In the first of two clinic studies, 20 adults with excess facial redness had either 633 nm red plus 830 nm near-infrared LED light or IPL, 10 per group, and a 3D skin camera measured haemoglobin. Naranjo García, 2023
- Redness: all 10 in the LED group improved moderately; 9 of 10 in the IPL group improved markedly.
- Comfort: 7 of 10 in the LED group felt no pain; everyone in the IPL group reported severe pain.
- Side effects: none were reported with LED.
The study was small and open-label, and it measured diffuse redness rather than individual veins.
In the second, a rosacea study of 90 patients found an effective rate of 73.3% with IPL, 66.7% with LED and 40.0% with medication alone; IPL and LED did not differ significantly. Zhang and Song, 2025 LED helped redness and itching more than visible vessels.
So the realistic plan for red light therapy for broken capillaries is light for the surrounding skin and a vascular treatment for the vessels. The AAD lists redness among the discolouration red light may help. AAD, 2024 Our red light therapy for redness and red light therapy for rosacea articles go deeper.
What settings did the LED redness studies use?
They used short sessions of red, amber or near-infrared light, about twice a week, over a few weeks. All of it was applied to the skin from outside the body.
| Study | Who | Light | Session | Schedule | Measured |
|---|---|---|---|---|---|
| Zhang and Song, 2025 | Rosacea, 30 per group, with medication | 590 nm at 25 mW/cm2, then 830 nm at 50 mW/cm2 | 10 + 10 minutes | Twice a week for 3 weeks | Effective rate 66.7% with LED |
| Naranjo García, 2023 | Facial redness, 10 LED and 10 IPL | 633 nm + 830 nm | Not in the abstract | Not in the abstract | Redness: moderate improvement |
| Gavish, 2020 | 20 healthy adults, randomised | 830 nm vs 633 nm, over the wrist | 5 minutes | One session | Short rise in small-vessel blood flow with 830 nm |
The Gavish study looked at small vessels for a short time, not at redness or veins. Gavish, 2020 To stay near the studied range at home, start with lower brightness, a shorter timer and, for the panel, more distance.
Can red light make flushing or broken capillaries worse?
In the studies above, LED caused no side effects in one and only mild reactions in the other. Warmth can still set off a flush in reactive skin, so start low and short.
Near-infrared is the part you feel as gentle warmth. A pink flush that fades within the hour is a normal response; redness that lasts hours means the session was too long or too bright. Heat is a common rosacea trigger, and the NHS advises avoiding heat, sunlight and humid conditions where possible. NHS, 2023
More light is not always better: the research shows "a pronounced biphasic dose response", so moderate doses tend to do more than very large ones. Hamblin, 2017
- Cool skin first: not straight after a hot shower, a workout or a hot drink.
- Flush log: note how long any pinkness lasts after each session.
- Stop: if redness lasts hours, or if burning or a rash appears.
How long after laser, IPL or sclerotherapy can you use red light?
Wait until the treated skin has fully healed and your practitioner agrees, because freshly treated skin counts as broken skin and our precautions rule out light on it. No source sets a fixed waiting time for home LED, so the practitioner's advice comes first.
After a facial vein laser, redness usually lasts 4 to 8 hours and mild swelling several days. ASDS After a pulsed dye laser, purple bruising lasts about a week. North Bristol NHS Trust
After laser treatment of leg veins, the AAD advises protecting treated areas from the sun for 3 to 4 weeks, and compression stockings are usually worn for 2 to 3 weeks after sclerotherapy. AAD, 2026 Once healed and cleared, begin with a short, low session.
Does red light help varicose veins or spider veins on the legs?
No: light on the skin does not close a vein that lets blood flow backwards, and varicose veins need a GP or vein specialist first. Leg spider veins are usually harmless, but some signs need a doctor before any home device.
Varicose veins come from faulty valves and are "not usually serious". NHS, 2024 Compression stockings are often the first approach. Mayo Clinic, 2024
- See a GP: pain, itching or swelling, worsening veins, or a leg sore not healed after 2 weeks.
- Urgent: a bleeding vein, or one swollen, warm, painful calf, which may be a clot; do not use light.
- Skin changes: a rash, sores, colour changes, burning or cramping legs. Cleveland Clinic, 2026
Self-care helps prevent new leg veins, though it does not remove existing ones: exercise, raised legs, a break every 30 minutes and year-round sun protection. AAD, 2026 For the panel on calves and thighs, see red light therapy for legs.
Do spider veins come back, and can sunscreen prevent new ones?
They can come back: treated vessels can reopen and new ones can form, so most plans include touch-ups. Daily sunscreen is the most useful habit for the face, because sun damage is the main cause there.
Facial laser is not a one-time treatment, with touch-ups every six months to one year. Cleveland Clinic, 2025 For rosacea, results for visible vessels tend to last 3 to 5 years, though "new ones can form". AAD
In a trial of 903 adults over about 4.5 years, daily sunscreen users showed 24% less skin ageing than discretionary users. Hughes, 2013 Our devices produce no UV and give no sun protection, so use light first on bare skin, then skincare, then sunscreen, as our red light therapy for sun damage article sets out.
Is red light suitable during pregnancy, with rosacea medicine or on darker skin?
Our precautions rule out use during pregnancy, and the panel manual also lists breastfeeding and preparing for pregnancy. Anyone taking a medicine, or with darker skin, should check before starting.
- Pregnancy: the NHS says varicose veins often improve after birth. NHS, 2024 See red light therapy while pregnant.
- Medicines: some rosacea tablets, such as doxycycline, make skin more sensitive to sunlight. Our precautions rule out use with photosensitising medication, so anyone taking a medicine should check with their pharmacist or doctor before using the device.
- Darker skin: it can be more sensitive to visible light, including red light, so talk with a dermatologist first. AAD, 2024 The panel is not for Fitzpatrick skin types V or VI.
- New vessels: liver or connective tissue disease can cause them, so show a new or bleeding cluster to a dermatologist. DermNet, 2025
How do you use a red light mask or panel for skin with broken capillaries?
Use the mask's red mode on the face, and the panel for the neck, upper chest and legs, starting low and short. Both sit alongside a dermatologist's vascular treatment and daily sunscreen, not in place of them.
The 4-Wavelength Red Light Therapy Mask is a cordless, full-face silicone shell with an eye opening and no diodes over the eyes, run by voice or the handheld controller.
- Mode: the red mode (665 nm red with 850 nm and 1064 nm near-infrared). The blue mode is for breakouts; leave it out here.
- Start: 50% brightness, 5-minute timer, two to three times a week, on clean, dry, unbroken skin.
- Build up: 10 minutes once any flush fades within the hour, then 70% and 90% brightness while skin stays calm.
- Limits: 10-minute sessions up to 4 times a week at high brightness, or 15-minute sessions up to 3 times a week, never more than 20 minutes a day.
- Eyes and tracking: eyes closed, never look into the light; photos at weeks 0, 4 and 8.
The 9-Spectrum Red Light Therapy Panel carries 480, 590, 630, 660, 670, 810, 830, 850 and 1060 nm, each dimmable from 1 to 100%, including the 590 nm and 830 nm pair from the rosacea study.
- Position: hang it on a door or wall with the included door hook, pulley, hanging cables and screws, or stand it upright on the floor (a floor stand is sold separately).
- Neck and upper chest: level with the upper chest, about 12 inches away, chin slightly raised, never aimed straight at the face.
- Legs: about 12 inches for both calves or thighs, 6 inches for one calf, on bare skin.
- Settings: each channel well below 100%, 480 nm at its lowest if skin marks easily, a few minutes at first (the timer sets from 1 minute), working towards 10 to 15 minutes per area.
- Warmth and eyes: the surface stays at or below 40°C; if skin feels hot, lower the near-infrared channels or step back. Goggles on, eyes closed, and at least 6 hours between 30-minute sessions.
