Most bruises heal completely within about two weeks. A minor bump might fade in 10 days, while a deeper or more forceful injury can linger for three to four weeks. The timeline depends on where the bruise is, how hard the impact was, your age, and whether you’re taking certain medications.
The Typical Healing Timeline
A bruise forms when small blood vessels under the skin break from an impact, leaking blood into the surrounding tissue. Your body immediately starts cleaning up that trapped blood, and the visible color changes on your skin are a real-time window into that process.
In the first day or two, the bruise looks red or dark pink as fresh blood pools beneath the skin. Over the next few days, that blood loses oxygen and the bruise shifts to a blue or dark purple. Around days five through seven, the body begins breaking down the hemoglobin in the trapped blood cells, producing pigments that turn the bruise green. In the final stage, those pigments convert further into a yellow or brown tone before fading entirely. On darker skin tones, these color shifts may be harder to see on the surface, but the same biological process is happening underneath.
Not every bruise follows this sequence neatly. A light bruise from bumping a table might skip straight from reddish-purple to yellowish-brown in under a week. A deep bruise from a hard fall could cycle through every color over three or more weeks.
Why Location Matters
Bruises on your legs tend to heal more slowly than bruises on your face or upper body. Gravity pulls blood downward, which means leaked blood in the lower extremities spreads more and takes longer for your body to reabsorb. Blood flow also plays a role: the face has a rich blood supply that delivers cleanup cells quickly, while the shins and calves have comparatively less circulation.
Bruises over bony areas like the shin or knee can also feel more painful and look more dramatic because there’s less cushioning tissue to absorb the initial impact, so more small vessels break at once.
Why Bruises Last Longer as You Age
If you’ve noticed bruises sticking around longer than they used to, or appearing from bumps that wouldn’t have left a mark years ago, aging skin is the most common explanation. Several things change as you get older that make bruising easier and slower to resolve.
The skin loses collagen and elastin over time, partly driven by the stress hormone cortisol, which breaks down these structural proteins. Thinner skin means less padding around blood vessels, so even minor contact can cause a bruise. At the same time, the walls of small blood vessels become more fragile. Once a bruise forms, the inflammatory phase of healing takes longer in older skin, and cells don’t replicate as efficiently to repair the damage. A bruise that would vanish in 10 days on a 25-year-old might take three full weeks on a 65-year-old.
Medications That Slow Healing
Blood-thinning medications are the biggest factor outside of age. Anticoagulants like warfarin slow your body’s ability to form clots, while antiplatelet drugs like aspirin and clopidogrel prevent blood cells from clumping together. Both types mean more blood escapes from damaged vessels before the leak seals, creating larger bruises that take longer to clear.
Over-the-counter pain relievers like ibuprofen and naproxen also have a mild blood-thinning effect. Taking one of these after an injury can make the resulting bruise bigger and slower to fade. If you bruise easily and take any of these medications regularly, that connection is worth noting, but don’t stop prescribed blood thinners without talking to your prescriber.
Certain supplements, including fish oil, vitamin E, and ginkgo biloba, can have similar effects on clotting and bruise duration.
How to Help a Bruise Heal Faster
The most effective thing you can do is apply ice early. Wrap an ice pack in a thin towel and hold it on the bruised area for 20 minutes at a time, repeating several times over the first day or two. Cold constricts the broken blood vessels and limits how much blood leaks into the tissue, which means a smaller, faster-healing bruise.
Elevating the bruised area above your heart, when practical, also helps by reducing blood flow to the injury site. For a bruised leg, propping it up on pillows while you’re on the couch is enough. After the first 48 hours, gentle warmth from a warm compress can help increase circulation to the area and speed up the body’s reabsorption of the trapped blood.
Bruises vs. Hematomas
A standard bruise is blood that has spread thinly through the tissue under the skin. A hematoma is a pool of blood that collects in one spot, often forming a firm, swollen lump you can feel. Hematomas result from more forceful injuries and involve larger or deeper blood vessels.
Small hematomas resolve on their own, though they take longer than flat bruises. If a hematoma keeps expanding over several days, feels increasingly painful, or limits movement in a nearby joint, that warrants a medical visit. Large hematomas sometimes need to be drained.
When Bruising Signals Something Else
Bruises from a known bump or fall are rarely a concern, even if they look dramatic. The bruises worth paying attention to are the ones you can’t explain.
Frequent bruising without clear injuries can signal a problem with platelets, the blood cells responsible for clotting. Platelet disorders often show up first as tiny red or purple dots on lighter skin (or brown dots on darker skin) called petechiae, which look like a fine rash rather than a typical bruise. These may progress to larger purple patches or full bruises if the underlying condition worsens. Bleeding from the gums or nose without obvious cause is another related warning sign.
Bruises that appear in unusual locations, like the torso or back, where you haven’t had any impact, deserve more attention than bruises on shins and forearms where everyday bumps are common. The same is true for bruises that seem far too large for the injury that caused them, or bruises that haven’t shown any color change after two weeks. In these cases, a simple blood test can check your platelet count and clotting function to rule out an underlying bleeding disorder.
