Most bruises heal completely within two weeks. Smaller bruises from minor bumps can fade in as little as a few days, while larger or deeper bruises may take three weeks or slightly longer. The timeline depends on factors like your age, the force of the injury, and whether you take certain medications.
The Typical Healing Timeline
A standard bruise goes through a predictable sequence driven by your body breaking down trapped blood beneath the skin. When small blood vessels rupture from an impact, red blood cells leak into the surrounding tissue. Your immune system then sends specialized cells to clean up the spilled blood, and that cleanup process is what you see as shifting colors over the days that follow.
In the first day or two, a bruise looks red or dark purple because of the fresh hemoglobin pooled under your skin. Over the next several days, your body starts breaking that hemoglobin down into different pigments. First it converts to a green-tinted compound, which is why bruises often look greenish around days five through seven. That green pigment then converts into a yellow one, giving the bruise its characteristic yellowish or brownish look in the second week. The iron left over from the process gets stored as a brownish pigment, which is sometimes the last color you notice before the bruise disappears entirely.
Not every bruise follows this sequence perfectly. A small bruise might skip noticeable stages and simply fade, while a deep one can look dark purple for a full week before the color starts shifting.
What Makes Some Bruises Last Longer
The harder the impact and the deeper the injury, the more blood leaks into the tissue, and the longer it takes your body to clear it out. A bruise on your shin from walking into a coffee table will generally resolve faster than one from a hard fall during sports, simply because there’s less trapped blood to process.
Location matters too. Areas with more loose, soft tissue, like the inner arm or thigh, tend to bruise more dramatically because blood can spread more easily through the tissue. Bruises on the face often heal faster than bruises on the legs, partly because of better blood flow to the head and partly because leg bruises are fighting gravity, which slows drainage.
Age and Skin Changes
Children and older adults bruise more easily than young, healthy adults. As you age, your skin loses structural support and the tissues underneath become looser, allowing blood to spread more freely after an impact. This means bruises in older adults tend to be larger and take longer to resolve. The blood vessels themselves also become more fragile with age, so less force is needed to cause a bruise in the first place.
Conditions like high blood pressure and clotting disorders also affect how extensively you bruise and how quickly the bruise clears. If you notice that bruises seem bigger or slower to heal than they used to be, aging skin is the most common explanation, but it’s worth mentioning to your doctor if the change is dramatic or sudden.
Medications That Slow Healing
Several common medications can make bruises larger, more frequent, or slower to fade. The most well-known culprits are blood thinners like warfarin and rivaroxaban, which interfere with your blood’s ability to clot. When clotting is delayed, more blood escapes into the tissue before the leak seals, creating a bigger bruise that takes longer to clear.
Over-the-counter pain relievers like ibuprofen also play a role. They block an enzyme involved in clotting and inflammation, which can extend bleeding time after an injury. If you take ibuprofen regularly and notice you bruise easily, that connection is well established. Aspirin works similarly.
Corticosteroids like prednisone affect bruise healing differently. They thin the skin over time and interfere with tissue repair, making bruises more likely and slower to resolve. Chemotherapy drugs, immunosuppressants, and certain medications used for autoimmune conditions can also delay healing by suppressing the immune cells responsible for cleaning up the trapped blood.
Bruises vs. Hematomas
A regular bruise is a flat discoloration under the skin. A hematoma is a deeper collection of blood that forms a firm, swollen lump. Hematomas hurt more, take longer to heal, and sometimes signal a more serious injury like a fracture or internal bleeding. If a bruise feels raised and solid rather than flat, or if the swelling keeps growing after the injury, that’s a sign you’re dealing with a hematoma rather than a simple bruise.
While a typical bruise resolves in one to three weeks, a significant hematoma can persist for a month or more. Large hematomas occasionally need to be drained by a doctor if they aren’t reabsorbing on their own.
How to Speed Up Healing
Icing a fresh bruise in the first 24 to 48 hours helps constrict the damaged blood vessels, limiting how much blood leaks into the tissue. Less leaked blood means a smaller bruise and a shorter healing time. Apply ice wrapped in a cloth for 15 to 20 minutes at a time, with breaks in between.
After the first couple of days, gentle warmth can help by increasing blood flow to the area, which speeds up your body’s ability to clear the trapped blood. Elevating the bruised area, when practical, also helps by encouraging drainage. Compression with a bandage can limit swelling on limbs, especially right after the injury.
None of these methods will make a bruise vanish overnight, but they can shave days off the healing process, particularly for larger bruises.
Signs a Bruise Needs Medical Attention
A bruise that hasn’t faded at all after two weeks is worth having evaluated. Other signs to watch for include a bruise that keeps growing in size, painful swelling that doesn’t improve, or a firm lump that persists at the injury site. Bruises around the eye that affect your vision need prompt attention.
Unexplained bruising, meaning bruises that appear without any injury you can remember, can sometimes point to a clotting disorder or other underlying condition. The same applies if you’re getting frequent large bruises, noticing bruises that keep recurring in the same spot, or experiencing unusual bleeding elsewhere like nosebleeds or blood in your urine. Any of these patterns are worth discussing with a healthcare provider, especially if they’re new for you.
