Most bruises heal completely within about two weeks. Smaller, superficial bruises often fade faster, while deeper or more severe bruises can take a month or longer to fully disappear. The timeline depends on factors like the bruise’s size, its location on your body, and your overall health.
The Two-Week Healing Timeline
A typical bruise goes through a predictable color sequence as your body breaks down and reabsorbs the trapped blood beneath the skin. In the first minutes after impact, the bruise appears pinkish or deep red because the leaked blood still carries oxygen. Within hours, that oxygen is released into surrounding tissue and the bruise darkens to a deep purple or blue.
Over the next several days, your body starts breaking down the blood pigment through a chemical chain reaction. The purple fades to a blue-green as the pigment converts into a greenish compound, then shifts to yellow as it breaks down further, and finally turns a golden brown before being cleared away entirely. Most people notice the green-yellow transition around days five through seven, with the pale yellow stage lasting through the end of the second week.
This entire process typically wraps up in about 14 days for an average bruise on an otherwise healthy adult. Bruises on your legs often take longer than bruises on your arms or face, partly because gravity pulls more blood downward and partly because circulation in the lower limbs is slower.
When Bruises Take Longer Than Two Weeks
Not every bruise follows the standard timeline. A hematoma, which is a larger, raised collection of blood that’s often painful to touch, can take a month or more to resolve. These form from harder impacts that damage deeper or larger blood vessels, trapping a bigger pool of blood that your body needs more time to process. You can sometimes feel a firm lump beneath the skin with a hematoma, unlike the flat discoloration of a regular bruise.
Location matters too. Bruises near joints or on the lower legs tend to linger because those areas experience more movement and have less robust blood flow. Bruises on soft, fatty tissue like the thighs or buttocks can also spread out and look more dramatic, even though they’re not necessarily more serious.
Medications That Slow Healing
Several common medications can make bruises worse, larger, or slower to heal. Blood thinners are the most obvious culprits. They reduce your blood’s ability to clot, so more blood leaks out from the initial injury and the bruise takes longer to stabilize and reabsorb.
Long-term use of anti-inflammatory painkillers like ibuprofen and naproxen can also impair healing. Short-term use has limited impact, but regular, higher-dose use interferes with the inflammatory process your body relies on to clean up damaged tissue. Corticosteroids, whether taken as pills or applied to skin over long periods, are particularly notorious for slowing healing. They suppress nearly every phase of tissue repair and, over time, thin the skin itself, making you more prone to bruising in the first place.
If you take any of these medications and notice that bruises routinely last three or four weeks, the medication is likely a factor.
Nutritional Factors
Vitamin and mineral deficiencies can contribute to easier bruising and slower recovery, though this is relatively uncommon in people eating a varied diet. Vitamin C plays a direct role in building collagen, the structural protein that strengthens blood vessel walls. Severe vitamin C deficiency (scurvy) is rare today, but even mildly low levels can weaken capillaries enough to increase bruising. Zinc deficiency and low B vitamins can also contribute to skin that bruises more readily.
If you bruise frequently without obvious cause, it’s worth looking at your diet before assuming something more serious is going on. Citrus fruits, bell peppers, leafy greens, and lean meats cover most of the nutrients involved in bruise recovery.
How to Speed Up Healing
The first few hours after an injury are your best window to reduce a bruise’s eventual size and duration. Applying ice (wrapped in a cloth, not directly on skin) constricts the damaged blood vessels and limits how much blood leaks into the surrounding tissue. Ice is most effective within the first eight hours after injury. You can continue using rest, ice, compression, and elevation during the first 72 hours, but the early application matters most.
After the first couple of days, gentle warmth can help increase circulation to the area and speed up the breakdown of trapped blood. A warm washcloth or heating pad for 10 to 15 minutes a few times a day is enough. Keeping a bruised limb elevated when you’re sitting or lying down also helps your body drain the pooled blood more efficiently.
There’s no way to make a bruise vanish overnight. But combining early ice with later warmth and elevation can shave a few days off the typical two-week timeline.
Signs a Bruise Needs Attention
A bruise that hasn’t changed color or started fading after two weeks is worth getting checked. The same goes for bruises that keep growing days after the injury, bruises that feel increasingly painful rather than improving, or any bruise accompanied by significant swelling or a hard lump that doesn’t soften over time.
Unexplained bruising, meaning bruises that appear without any injury you can recall, is a separate concern. Occasional mystery bruises are normal, especially on the shins and forearms. But frequent unexplained bruising, particularly if combined with bleeding gums, nosebleeds, or tiny red dots on the skin, can signal a problem with your blood’s ability to clot and warrants evaluation.
