The most effective thing you can put on sore nipples depends on what’s causing the soreness, but for the most common scenario, friction and damage from breastfeeding, purified lanolin is a strong first choice. In a study published by Karger Publishers, lanolin healed nipple trauma faster than expressed breast milk, with meaningful reductions in pain by day three. Beyond lanolin, several other topicals and home remedies can help, and knowing which to reach for starts with understanding what’s actually going on with your skin.
Lanolin: The Go-To for Cracked Nipples
Medical-grade lanolin (often sold as “HPA lanolin”) is a thick, waxy substance derived from sheep’s wool. It works by creating a moisture barrier over damaged skin, preventing the cracks from drying out further while still allowing air exchange. You apply a pea-sized amount after each feeding, and there’s no need to wash it off before the next one, which makes it practical for round-the-clock nursing schedules.
Compared to simply applying expressed breast milk and letting it air dry, lanolin performs better. Research found an absolute risk reduction of 0.43 for nipple trauma healing and 0.61 for pain reduction on day three when comparing lanolin to breast milk alone. That said, expressed breast milk isn’t useless. Rubbing a few drops onto your nipples after a feed and letting them air dry is a free, always-available option that does offer some protection, especially for mild soreness that hasn’t progressed to visible cracks.
Natural Oils and Other Topicals
A large meta-analysis in Frontiers in Global Women’s Health reviewed 11 studies on topical preparations for nipple pain and found that a wide range of natural products have been tested: coconut oil, olive oil, aloe vera gel, cocoa butter, beeswax, and even mountain honey. Most of these work on the same basic principle as lanolin, keeping damaged skin moist so it can repair itself rather than splitting further.
Coconut oil is a popular choice because it’s affordable, widely available, and has mild antimicrobial properties. Olive oil is similarly accessible. If you already have one of these in your kitchen, applying a thin layer after feeding is a reasonable approach for mild soreness. The key with any of these is consistency: apply after every feed, not just once a day.
One important caution with any product you put on your nipples: check the ingredient list carefully. The FDA has warned that certain nipple creams contain chlorphenesin and phenoxyethanol, two preservatives that can cause respiratory distress, vomiting, or diarrhea in infants. These two ingredients can also interact with each other, compounding the risk of breathing problems. Stick with products that have short, recognizable ingredient lists, and avoid anything that requires you to wash it off before nursing unless you’re confident you’ll remember every time.
Saline Soaks for Raw or Broken Skin
If your nipples are raw, cracked, or have open wounds, a warm saline soak can clean the area gently and promote healing. The recipe is simple: dissolve half a teaspoon of table salt or sea salt in 8 ounces of very warm water. You can also use Epsom salt at a higher concentration, about 2 tablespoons per 8 ounces of warm water. Soak the affected nipple for a few minutes, once a day, then pat dry gently and follow up with lanolin or another moisturizing barrier.
Saline soaks aren’t a standalone treatment, but they’re a useful addition when soreness has progressed to visible damage. The warm water increases blood flow to the area, and the salt creates an environment that discourages bacterial growth on broken skin.
Silver Nursing Cups and Hydrogel Pads
Silver nursing cups are small, dome-shaped caps that sit over your nipples inside your bra between feedings. They provide physical protection so fabric doesn’t rub against damaged skin, and the silver is thought to discourage bacterial growth on the surface. They’re reusable, easy to clean, and don’t involve applying any substance that your baby might ingest. The main drawback is cost, typically $30 to $60 for a pair.
Hydrogel pads are another barrier option. These are soft, gel-based discs that cool on contact and keep the wound environment moist. They can feel soothing, especially in the early days when every brush of fabric against your nipples is painful. However, there are risks worth knowing about. FDA reports have documented cases where hydrogel pads caused rashes, either from glycerin allergies (glycerin is a core ingredient in most hydrogel pads) or from pathogens that colonized the exposed gel surface and were then introduced to broken skin. If you use hydrogel pads, change them regularly, store them in a clean container, and stop immediately if you notice any rash or increased redness.
Figuring Out What’s Causing the Soreness
Topicals treat the symptom, but if the underlying cause isn’t addressed, the soreness will keep coming back. The most common cause of nipple pain in breastfeeding is a shallow latch, where the baby isn’t taking enough breast tissue into their mouth and instead compresses just the nipple. A lactation consultant can assess this in a single visit and often fix it with small positioning adjustments.
Not all nipple pain is friction damage, though, and putting lanolin on a problem that isn’t a wound won’t help. Two conditions are commonly mistaken for ordinary soreness:
- Nipple thrush is a fungal infection that causes burning, stinging pain that continues between feedings. The skin may look shiny, flaky, or unusually pink. It often develops after antibiotic use and requires antifungal treatment, not just a topical cream.
- Nipple vasospasm is a circulation issue where blood vessels in the nipple constrict, cutting off blood flow. You’ll notice the nipple turning white, then possibly blue or purple, before flushing back to its normal color. The pain is intense, burning, and throbbing, and it’s worse in cold air. Women with a family history of Raynaud’s phenomenon or who tend to have cold hands and feet are more prone to this. Keeping your chest warm after feeding and avoiding cold air exposure on bare nipples are first-line strategies.
If your nipples blanch white after feeds, that points toward vasospasm. If the pain is a deep burning that persists even when you’re not nursing and the skin looks unusually shiny, suspect thrush. If the pain is worst during the feed itself and your nipples look flattened or misshapen when they come out of your baby’s mouth, that’s almost certainly a latch issue.
Signs the Problem Has Gone Beyond Soreness
Sore nipples can sometimes be an entry point for infection, especially when the skin is cracked. Mastitis, a breast infection, develops when bacteria enter through damaged nipple tissue. Symptoms come on suddenly and can include breast tenderness or warmth, swelling, a hard lump, pain or burning that’s constant or occurs during feeding, and skin redness that often appears in a wedge-shaped pattern. On darker skin tones, the redness may be harder to spot, so pay attention to warmth and swelling instead. A fever of 101°F (38.3°C) or higher alongside any of these symptoms is a clear signal that what you’re dealing with has moved beyond simple nipple soreness and needs medical attention.
