Most bruises heal completely within about two weeks. A minor bump might fade in a week or less, while a deeper or more severe bruise can linger for three to four weeks, especially on the lower legs. The timeline depends on how much blood leaked under the skin, where the bruise is located, and your overall health.
The Typical Healing Timeline
A bruise forms when small blood vessels near the skin’s surface break from an impact, allowing blood to pool in the surrounding tissue. Over the next two weeks, your body gradually breaks down that trapped blood and reabsorbs it. You can actually track this process by watching the color change.
In the first day or two, a bruise appears pinkish or red as fresh blood collects under the skin. Over the next few days it deepens to dark blue or purple. By around day five or six, it begins shifting to a greenish or violet tone. In the final stage, the bruise turns dark yellow, then pale yellow before disappearing entirely. These color shifts happen because your body is breaking down hemoglobin, the oxygen-carrying molecule in red blood cells, into different byproducts that each have a distinct color.
Not every bruise follows this schedule exactly. A small bruise on your forearm might skip the green phase entirely and fade within a week. A large, deep bruise on your thigh could take three weeks or more to work through every color stage.
Why Some Bruises Take Longer to Heal
Several factors influence how quickly a bruise fades:
- Location on the body. Bruises on the legs heal more slowly than bruises on the arms or face. Blood pools downward with gravity, and circulation in the lower extremities is slower, so your body takes longer to clear the trapped blood.
- Severity of the injury. A light bump that produces a quarter-sized bruise resolves faster than a hard impact that causes widespread bleeding under the skin. Larger bruises simply have more blood for your body to process.
- Age. As you get older, your skin thins and loses some of the fatty tissue that cushions blood vessels. This makes bruising easier and healing slower. Older adults commonly notice bruises lasting well past the two-week mark.
- Medications. Blood thinners and certain supplements reduce your blood’s ability to clot. When clotting is slower, more blood escapes from damaged capillaries before the leak seals, producing a bigger bruise that takes longer to fade.
Bruises vs. Hematomas
A standard bruise is a thin layer of blood spread out just beneath the skin. A hematoma is a more concentrated collection of blood that fills a space inside your body, often from a more forceful injury. Hematomas tend to feel firm or lumpy to the touch and can be noticeably swollen, while a regular bruise is flat.
Small hematomas near the surface often heal on their own, though they take longer than a typical bruise. Larger or deeper hematomas sometimes need medical attention, including drainage with a needle or even surgery to repair damaged blood vessels. If a bruise feels unusually hard, keeps growing, or hasn’t improved at all after two weeks, it may be a hematoma worth having evaluated.
How to Speed Up Healing
You can’t make a bruise vanish overnight, but you can shorten the process and limit its size in the first hours after an injury. The key is to reduce how much blood leaks out of the damaged vessels before they seal.
Apply ice as soon as possible. Wrap an ice pack in a towel and hold it on the area for 10 to 20 minutes at a time, repeating every hour or two during the first eight hours. Cold constricts blood vessels, slowing the flow of blood into the tissue and keeping the bruise smaller. After the first day, ice has less effect because the bleeding has already stopped.
Elevation also helps. Raising the bruised area above your heart lets gravity work in your favor, draining fluid away from the injury and reducing both swelling and the amount of blood that pools. If you’ve bruised your shin, for example, lying down with your leg propped on pillows for the first evening makes a real difference.
Compression with an elastic bandage can provide gentle pressure that limits swelling, and rest prevents further damage to the area. Together, these four steps (rest, ice, compression, elevation) are the standard home approach for fresh bruises and soft tissue injuries.
When a Bruise Is Worth Investigating
A single bruise from a known bump or fall is rarely a concern, even if it takes a couple of weeks to fade. But certain patterns deserve attention.
Bruises that appear without any trauma you can remember, especially if they’re larger than a centimeter or show up frequently, can signal a bleeding disorder or a medication side effect. A family history of excessive bleeding raises that risk further. If you’re taking blood thinners or supplements and notice you’re bruising more easily, bring it up with your doctor rather than stopping the medication on your own.
In children, bruising in unusual locations (the torso, back, or face rather than shins and knees) or bruises that form patterns matching objects are recognized red flags for non-accidental injury. Bruises in infants who aren’t yet crawling or walking are particularly concerning, since immobile babies rarely bruise themselves.
Any bruise that hasn’t shown improvement after two weeks, continues to grow, or is accompanied by severe pain and swelling warrants a medical visit. These can indicate a hematoma that isn’t resolving on its own or, less commonly, an underlying condition affecting your blood’s ability to clot.
