Thread veins, also called spider veins or broken capillaries, are fine red, purple or bluish lines just under the skin. On the face they usually appear on the sides of the nose, the cheeks and the chin, sometimes with a background of general redness. On the legs they often form branching webs on the thighs and around the knees and ankles. Anyone researching thread veins treatment in Singapore should know that facial vessels and leg vessels behave differently, and are usually treated differently too.
The medical name is telangiectasia: small vessels near the surface that have widened and stayed that way. On the face, the usual causes are cumulative sun damage, rosacea, genetics and ageing, with hormonal change, alcohol, long-term use of strong prescription creams on the face and skin injury contributing in some people. On the legs, long hours standing, pregnancy, family history and pressure in the deeper veins play a bigger part. Thread veins themselves are harmless, but many people find them hard to cover.
A few red spots need a doctor's eye rather than cosmetic treatment, such as a vessel that bleeds easily, a spider-shaped spot with a central red dot, or many new vessels appearing quickly. SkinRev does not treat thread veins. Facial vessels are assessed and treated by Dr Sin Yong at IN Eternity Clinic, who also advises when leg veins need a vein check or a different approach first.
“Not every red line responds to the same laser — fine facial vessels, thick blue vessels and leg veins each need a different plan, and an honest assessment says which you have.”

What goes where
The honest ladder:
non-invasive first, medical when it is needed
At SkinRev Lab · non-invasive
There is no non-invasive treatment at SkinRev Lab that changes this concern. We will say so at the first visit and pass your enquiry to IN Eternity Clinic.
At IN Eternity Clinic · Dr Sin Yong
Laser Toning — Low-energy 1064 nm Q-switched Nd:YAG pulses passed across the face, used by Dr Sin Yong at IN Eternity Clinic for fine vessels set within general redness and uneven tone. Larger, thicker or isolated vessels may need a different vascular approach, which he will explain at assessment. How it works
少女光 Laser — The 少女光 Laser uses the DEKA RedTouch Pro, a 675 nm fractional laser with contact cooling that heats microzones of the dermis. It is used for redness that sits alongside pores and texture, rather than as a dedicated treatment for single prominent vessels. How it works
Enquiries to SkinRev Lab about medical treatments are passed to IN Eternity Clinic, where Dr Sin Yong performs them.
There is no non-invasive SkinRev option for thread veins, so this concern starts with a doctor. Daily broad-spectrum sun protection and gentle skincare help limit new vessels in the meantime. See Dr Sin Yong if fine facial vessels or flushing bother you, if you are not sure whether redness is rosacea, or if vessels have appeared quickly. For leg veins, see a doctor first if you also have bulging varicose veins, aching, swelling, skin changes around the ankles or a history of clots, as the deeper veins may need checking before any surface treatment. Bring a list of any creams you use on your face and mention easy bruising or blood-thinning medicines, since both can affect how vessels respond and how the skin recovers.

What the research says
The evidence,
with sources
A systematic review of 152 randomised studies in rosacea, graded with the GRADE method, found low-to-moderate certainty evidence that laser and intense pulsed light reduce redness and, mainly, visible vessels. In a comparison on the nose, both a long-pulsed 1064 nm Nd:YAG laser and a pulsed dye laser improved rosacea-related vessels to a similar degree, but the Nd:YAG laser did better on thick, dilated vessels, while fine vessels within background redness responded better to the pulsed dye laser. Vessel type therefore guides the choice of device and settings.
For leg veins, a systematic review of 26 studies covering 1,991 patients found long-pulsed 1064 nm Nd:YAG laser a safe option for leg vessels up to 3 mm across, with clearance similar to injection treatment of the veins (sclerotherapy). Sclerotherapy was usually less painful and quicker to show change, and combining approaches gave better clearance in some studies. These findings come from long-pulsed settings, which differ from low-energy toning, so Dr Sin Yong tells you plainly when another approach or referral suits your vessels better. Individual results vary.

Common questions
Your questions,
answered
What does thread veins treatment in Singapore involve?
It starts with an assessment of the vessels: where they are, how thick they are, their colour and whether rosacea or sun damage sits behind them. Fine facial vessels within general redness may be treated with laser at IN Eternity Clinic by Dr Sin Yong. Thicker vessels, or veins on the legs, may need a different device, injection treatment or a vein check, and he will say so plainly.
How much does thread veins treatment in Singapore cost?
Pricing is given at consultation at IN Eternity Clinic, because it depends on the number and size of vessels, the area involved and the laser plan. SkinRev does not treat thread veins, so there is no SkinRev price for this concern. You can enquire at SkinRev in CityLink Mall and we will route your enquiry to IN Eternity Clinic.
Will my thread veins come back after treatment?
Vessels that have been treated successfully usually stay cleared, but the tendency that caused them often remains. With ongoing sun exposure, rosacea or a family history, new vessels can form over months or years. Daily sun protection, managing rosacea and avoiding very hot water on the face help slow this, and occasional maintenance sessions may be discussed at follow-up if new vessels appear.
Can laser treat thread veins on my legs?
Leg veins are different from facial vessels. They sit deeper, carry higher pressure and are often linked to the larger veins beneath them. Research supports long-pulsed 1064 nm laser and injection treatment for small leg veins, but bulging varicose veins, aching or swelling should be checked first. Dr Sin Yong will advise whether the lasers listed here are suitable or whether another approach is better.
Does laser for thread veins hurt?
Most people feel a quick snapping or warm sensation with each pulse, and cooling is used to keep it tolerable. Afterwards the area may look red or slightly swollen for a few hours to a couple of days, and occasionally there is mild bruising. Avoid hot showers, saunas and strenuous exercise for a short time after treatment, and protect the area from sun.
How can I prevent new thread veins on my face?
Wear a broad-spectrum sunscreen every day, including on cloudy days and in the car, and add a hat in strong sun. Treat rosacea if you have it, wash with lukewarm rather than hot water, avoid harsh scrubbing and pore strips, and keep alcohol moderate if it makes you flush. These steps do not remove existing vessels but help limit new ones.
