Most people need two to four IPL sessions to clear broken capillaries on the face, with treatments spaced three to four weeks apart. The exact number depends on how many vessels you’re treating, how deep they sit in the skin, and how your body responds to the first session. Some people see significant fading after just one or two treatments, while others need up to five.
What a Typical Treatment Course Looks Like
In a study of 82 patients with visible facial blood vessels, the average number of IPL sessions was 2.4, with most people completing between two and four treatments. Sessions were spaced four weeks apart. A retrospective case series found a similar range of one to five treatments at intervals of two to five weeks. Ohio State’s Wexner Medical Center recommends three to five sessions at two-to-six-week intervals for optimal results.
The spacing matters. Your skin needs time to heal between sessions, and the treated vessels need time to be reabsorbed by your body. Going back too soon increases the risk of irritation without improving your results. Most clinics default to about four weeks between appointments, which gives any redness or bruising time to fully resolve before the next round.
How IPL Closes Broken Capillaries
IPL devices emit a broad spectrum of light wavelengths. When that light hits your skin, it’s absorbed by the hemoglobin inside the broken capillary. The light energy converts to heat, which damages the vessel wall and causes it to collapse. Over the following days and weeks, your body’s immune system clears the damaged vessel. The surrounding tissue is left intact because the light preferentially targets the red pigment in blood rather than the rest of the skin.
Shorter wavelength filters (around 515 to 560 nanometers) work best for superficial capillaries close to the skin’s surface, while longer wavelengths can reach deeper vessels. Your provider adjusts these settings based on the size, depth, and location of your capillaries.
How Much Clearance to Expect
A meta-analysis found that about 78% of IPL patients achieved greater than 75% clearance of their visible vessels after a full treatment course. Nearly 89% achieved at least 50% clearance. Those are strong numbers, but they also mean complete elimination isn’t guaranteed for everyone. You may see dramatic improvement while still having a faint trace of a vessel or two that’s deeper or more stubborn than the rest.
One case series using wavelength filters between 515 and 590 nanometers reported over 75% clearance in 81% of treated patients. The takeaway: most people get a significant visible improvement, and many see their broken capillaries essentially disappear.
What Recovery Feels Like
IPL for broken capillaries has minimal downtime, but the treated area does look worse before it looks better. Expect your skin to appear slightly redder than usual for two to five days after each session. Some tenderness or mild swelling can linger for up to a week. In rare cases, light bruising appears over the treated vessels and takes one to two weeks to fade.
If you’re also treating brown spots in the same session (which is common, since IPL targets pigment too), those spots will darken for three to seven days before flaking off. None of this typically requires any time away from work or daily activities, though you’ll want to avoid direct sun exposure and wear sunscreen diligently between sessions.
IPL Compared to Pulsed Dye Laser
Pulsed dye laser (PDL) is the other common option for broken capillaries, and patients often wonder which is better. A split-face study that treated one side with IPL and the other with PDL found both were equally effective at reducing facial redness. PDL has a slight edge in some analyses for very high clearance rates, but IPL treats a broader area per pulse and can address both redness and pigmentation in the same session, which makes it a popular choice for people dealing with general facial redness alongside specific broken vessels.
Session counts are similar for both. The choice often comes down to what your provider has in their office and whether you have additional skin concerns beyond the capillaries themselves.
Skin Tone and Candidacy
IPL works best on lighter skin tones (Fitzpatrick types I through III). If you have medium to dark skin, the melanin in your epidermis competes with hemoglobin for the light energy, which increases the risk of burns, darkening, or lightening of the treated skin. Providers can adjust settings for darker skin by using longer wavelengths, lower energy levels, and longer pulse durations, but the margin for error is thinner. If you have a deeper complexion, ask specifically about your provider’s experience treating your skin type with IPL, or whether a different vascular laser would be safer.
How Long Results Last
Once a broken capillary is destroyed by IPL, that specific vessel is gone permanently. Your body absorbs it and it doesn’t regenerate. However, the underlying factors that caused your capillaries to break in the first place, such as sun damage, rosacea, aging, or genetics, don’t stop after treatment. New broken capillaries can develop over time, which is why some people return for a single maintenance session once or twice a year to keep their skin clear. Consistent sunscreen use and avoiding known triggers (excessive heat, alcohol, harsh skincare products) can help extend your results.
