A busted blood vessel usually shows up as a bright red patch on the white of your eye, a flat purple-blue mark on your skin, or thin red lines across your cheeks or nose. The exact appearance depends on where the vessel broke, how deep it sits, and how much blood leaked out. Most are completely harmless and heal on their own, but knowing what’s normal helps you spot the rare cases that need attention.
In the Eye: Subconjunctival Hemorrhage
This is the most dramatic-looking version, and probably what brought you here. A broken blood vessel in the eye creates a vivid, bright red patch on the white part (the sclera). It can cover a small wedge or flood nearly the entire visible white surface with a deep crimson stain. Despite looking alarming, a straightforward subconjunctival hemorrhage causes no pain, no light sensitivity, and no change in your vision. If your eyesight is normal and nothing hurts, the appearance is almost always worse than the reality.
The red patch has sharp, well-defined edges where blood has pooled beneath the thin, clear membrane covering the white of your eye. It doesn’t affect the colored part of your eye or the pupil. You might notice it in the mirror one morning without any idea how it happened, since common triggers include sneezing, coughing, rubbing your eyes, or even sleeping in an awkward position.
Over the course of one to three weeks, the patch gradually shifts from bright red to a yellowish-brown as your body reabsorbs the trapped blood, similar to a bruise fading on your skin. No treatment speeds this up. Artificial tears can help if the spot feels mildly irritating, but the hemorrhage resolves entirely on its own.
When an Eye Hemorrhage Needs Attention
A simple broken vessel in the eye should not cause vision changes, pain, swelling, discharge, or sensitivity to light. If any of those symptoms are present, something more serious may be going on. Blood pooling inside the front chamber of the eye (rather than on the surface) can look like a visible crimson fluid level across the lower part of the iris, and it often comes with discomfort and light sensitivity. A hemorrhage that looks raised or balloon-like, rather than flat against the white of the eye, can indicate a deeper injury. Either of these warrants prompt medical evaluation.
On the Skin: Bruises and Hematomas
A standard bruise forms when small blood vessels beneath the skin break and leak blood into the surrounding tissue. At first it looks pinkish-red. Within hours to a day, it deepens to dark blue or purple as the trapped blood loses oxygen. Over the following days, the color shifts through a predictable sequence: violet, then green, then dark yellow, then pale yellow before fading completely. Most bruises finish this cycle in about two weeks.
The size and shape of a bruise depends on the force that caused it and the looseness of the tissue underneath. Bruises on the forearms, shins, and thighs tend to spread wider because there’s more room for blood to disperse. A bruise on the forehead, where skin is tighter against bone, often stays more contained but can swell noticeably.
A hematoma is a step up from a regular bruise. It forms when a larger volume of blood collects outside the vessel and pools into a defined pocket. You can usually feel the difference: a hematoma creates a raised, firm lump under the skin that’s tender to the touch, while a flat bruise stays level with the surrounding skin. Hematomas take longer to resolve and can feel warm or throb for several days.
Tiny Red Dots: Petechiae
Petechiae are pinpoint-sized red or reddish-purple dots, each typically smaller than 2 millimeters, caused by the tiniest blood vessels (capillaries) bursting just under the skin’s surface. They often cluster together rather than appearing as a single spot. A common, harmless cause is physical strain: forceful vomiting, intense coughing, heavy weightlifting, or even prolonged crying can produce a scattering of petechiae across the face, neck, and upper chest. In these cases, the dots appear immediately after the episode and fade within a few days.
There’s a simple way to tell petechiae apart from a regular rash. Press a clear glass or your fingertip firmly against the spot. A rash caused by dilated (but intact) blood vessels will temporarily turn white, or “blanch,” because you’re pushing the blood away through the vessels. Petechiae won’t blanch, because the blood has already leaked out of the vessel and is trapped in the tissue with nowhere to go. If you have widespread, unexplained petechiae that you can’t link to straining or minor trauma, that’s worth getting checked, as it can sometimes signal a clotting issue or infection.
Broken Capillaries on the Face
Broken capillaries on the face look like thin, visible red, blue, or purple lines just beneath the skin’s surface. They’re most common on the nose, mid-cheeks, and chin. Unlike a bruise, they don’t fade through a color cycle and disappear. These are permanently dilated tiny vessels, and they tend to stick around unless treated.
They come in a few distinct patterns. Linear ones look like simple thin lines. Arborizing telangiectasias branch out like tiny tree limbs. Spider-type vessels radiate outward from a single central point, forming a small cartwheel shape. Vessels fed by arteries tend to be finer, bright red, and flat against the skin. Those connected to veins run wider and bluer, and they sometimes protrude slightly above the surface. Over time, capillary-fed marks that started out fine and red can dilate further and shift toward purple or blue as blood pressure in the area increases.
Sun exposure, alcohol, rosacea, pregnancy, and aging all contribute to their development. They pose no health risk, but many people seek treatment for cosmetic reasons. Laser therapy and light-based treatments are the most common options and typically clear them in one to three sessions.
How To Tell What You’re Looking At
Location and size are your best clues. A bright red, flat, painless patch on the white of your eye is almost certainly a subconjunctival hemorrhage. A discolored area on your skin that’s sore and shifts from purple to green to yellow over days is a bruise. A cluster of pinpoint red dots on your face or chest after straining is petechiae. Thin, permanent red or blue lines on your nose and cheeks are broken facial capillaries.
A few features signal that a busted blood vessel is more than routine. On the skin, a bruise that keeps growing, feels very firm or warm, or appears without any injury you can recall, especially if you also notice easy bleeding elsewhere, is worth investigating. In the eye, pain, vision changes, light sensitivity, or a raised, balloon-like appearance over the hemorrhage all point to something beyond a simple broken vessel. Widespread petechiae with no clear trigger, particularly if accompanied by fever or fatigue, should be evaluated promptly.
