Cracked nipples appear as visible splits or fissures in the skin on or around the nipple, often accompanied by redness, flaking, and sometimes bleeding. They can range from barely-there surface dryness to deep, open wounds that bleed or scab over. Whether you’re breastfeeding, exercising, or just noticed changes and want to understand what you’re seeing, here’s how to identify cracked nipples and tell them apart from other conditions.
How Cracked Nipples Look at Each Stage
Nipple damage doesn’t happen all at once. It progresses through recognizable stages, and what you see depends on how far along the damage has gone.
In the earliest stage, the skin on and around the nipple looks dry, tight, and flaky. You might notice peeling similar to a mild sunburn. The nipple may appear slightly pinker or redder than usual, and the texture feels rough rather than smooth. At this point, the skin is irritated but still intact.
The next stage is where actual cracking begins. You’ll see thin lines or splits in the skin surface, similar to the fissures you’d get on severely chapped lips. These cracks often form across the tip of the nipple or at the base where the nipple meets the areola. The surrounding skin typically looks red and inflamed. Small amounts of clear or slightly yellowish fluid may seep from the fissures as the body tries to heal, and the area feels sore or stings, especially when touched or exposed to air.
Severe damage looks distinctly different. The fissures are deeper, and you may see active bleeding or dark scabbing over the cracks. The skin around the nipple can appear swollen, raw, or even partially torn. In some cases, the nipple looks misshapen after feeding sessions due to compression injury. At this stage, the pain is significant enough that it may interfere with breastfeeding or even wearing clothing comfortably.
Why Nipples Crack
The most common cause during breastfeeding is a poor latch. When a baby doesn’t take enough of the breast into their mouth, the nipple gets compressed against the hard palate repeatedly, creating friction damage. Tongue tie in infants can contribute to this because the baby’s tongue can’t move freely enough to cushion the nipple properly. Breast pump settings that are too high or flanges that don’t fit correctly cause similar mechanical trauma.
Outside of breastfeeding, repetitive friction is the main culprit. Runners and other athletes frequently develop what’s sometimes called “runner’s nipple,” where fabric rubs against the chest over miles of movement. The nipples can end up feeling raw or even bleeding through a shirt. This happens more often in cold or wet conditions when the skin is already more vulnerable, and it affects all genders.
Dry skin conditions, eczema, and contact reactions to soaps, lotions, or laundry detergents can also cause the nipple skin to crack. These tend to look more like a widespread rash with flaking rather than the localized fissures from mechanical friction.
Cracked Nipples vs. Other Conditions
Not everything that causes nipple redness or pain is a crack. A few conditions look similar but have different causes and need different approaches.
Nipple thrush (a yeast infection) was traditionally diagnosed based on visual signs like redness, cracked skin, and swelling around the nipples, often paired with shooting pain or itching. However, recent research has challenged this diagnosis significantly. Current evidence suggests there’s little to no proof that yeast infections actually occur on the nipple. What was previously attributed to thrush is now thought to result from other factors like improper latch, positioning problems, or reactions to irritants and allergens. If you’ve been told you have nipple thrush based on appearance alone, it may be worth getting a second opinion focused on latch assessment.
Nipple blebs are small, raised white dots on the nipple surface caused by a blocked pore. Milk backs up behind the blockage, creating a visible white spot. Despite their appearance, research confirms no connection between these white spots and fungal infection. They look distinctly different from cracks because they’re raised and localized to a single pore rather than forming a line or split across the skin.
Signs of Infection to Watch For
Open cracks in the skin create an entry point for bacteria, which is why infected nipple wounds are a real concern. The signs are distinct from normal healing. Look for redness that spreads outward from the crack rather than staying localized, heat radiating from the wound, increasing swelling, or a rash that extends beyond the nipple area. Persistent irritation that worsens instead of gradually improving is another red flag.
If bacteria travel deeper into the breast tissue, it can lead to mastitis, a breast infection marked by fever of 101°F (38.3°C) or higher, chills, and a section of the breast that feels hot, hard, or painful. Untreated mastitis can progress to an abscess, which is a pocket of pus within the breast tissue that may need to be drained.
How Cracked Nipples Heal
Most cracked nipples take anywhere from a few days to a few weeks to fully heal, though the soreness often improves well before the skin looks completely normal again. The biggest factor in healing speed is whether the cause of the damage has been addressed. A latch correction or pump adjustment can make the difference between a crack that heals in days and one that reopens every feeding.
For treatment, keeping the wound moist rather than letting it dry out promotes faster skin repair. Hydrogel dressings and lanolin ointment are the two most common options. In a randomized trial of 106 breastfeeding mothers, hydrogel dressings outperformed lanolin on multiple measures. The hydrogel group had significantly greater pain reduction by day 10 and day 12, and those mothers stopped needing treatment sooner. Perhaps most notably, the lanolin group experienced eight breast infections during the study while the hydrogel group had none.
For runner’s nipple or friction-related cracking, cleaning the area gently with mild soap and warm water is the first step. Pat the skin dry and apply petroleum jelly or ointment to protect the wound, then cover with gauze or a bandage. Preventing recurrence matters as much as treating the current damage: moisture-wicking fabrics, nipple covers, or athletic tape over the nipples before exercise can stop friction before it starts.
Severity and Breastfeeding Decisions
Clinical guidelines break nipple injuries into three tiers, each with different recommendations. For general soreness without visible cracks, the standard advice is to continue breastfeeding normally, apply lanolin, and seek support from a midwife or health visitor to check positioning. For painful, visibly cracked nipples, the same applies but with the addition of a nipple shield to protect the damaged area during feeds and a consultation with a lactation specialist. For severely damaged nipples with deep wounds or significant tissue loss, guidelines recommend stopping breastfeeding on the affected side temporarily to allow healing, while continuing on the other breast and expressing milk to maintain supply.
The distinction between these stages matters because pushing through severe damage can make things worse. A crack that might have healed in a few days with a brief rest can turn into a wound that takes weeks if it’s reopened at every feed. Knowing what stage your nipples are at helps you decide what level of intervention makes sense.
