Most internal styes clear up on their own within one to two weeks with consistent at-home care. An internal stye is a bacterial infection of the oil glands on the inner surface of your eyelid, which makes it more painful and harder to see than an external stye that forms along the lash line. The good news: the same simple treatment works for nearly all of them.
What Makes an Internal Stye Different
Your eyelids contain dozens of tiny oil-producing glands that help keep your tear film stable. An external stye develops at the base of an eyelash, so it’s visible right away. An internal stye, by contrast, forms deeper inside the lid when one of these oil glands (called a meibomian gland) gets blocked and infected, usually by staphylococcal bacteria. You’ll feel a tender, swollen bump, but it sits on the inner surface of the eyelid rather than the outer edge.
Because it’s deeper, an internal stye tends to be more painful and can cause more overall lid swelling. You might notice redness, a feeling of pressure in the eyelid, watery eyes, or the sensation that something is in your eye. Flipping the lid gently in front of a mirror sometimes reveals a small, red, raised area on the inside surface.
Warm Compresses Are the First-Line Treatment
A warm, moist compress is the single most effective thing you can do. The heat softens the hardened oil plugging the gland, encourages blood flow to the area, and helps the stye drain naturally. Kaiser Permanente recommends applying a warm, moist compress for 5 to 10 minutes, 3 to 6 times a day. That frequency matters: doing it once or twice won’t generate enough cumulative heat to unblock the gland.
Use a clean washcloth soaked in comfortably warm water, not hot. Do not heat a wet cloth in a microwave, as the temperature can spike unevenly and burn the delicate eyelid skin. A better option for sustained heat is a microwavable eye mask designed for this purpose, since washcloths cool quickly and need to be rewarmed every couple of minutes. Hold the compress gently against the closed eyelid and let the warmth do the work.
After removing the compress, you can lightly massage the eyelid with a clean fingertip, pressing gently toward the lash line. This helps move softened oil out of the blocked gland. Wash your hands thoroughly before and after touching your eyelid.
What Not to Do
Resist the urge to squeeze or pop an internal stye. Because it sits inside the lid, squeezing can push the infection deeper into the tissue or spread bacteria across the eyelid. It can also damage the gland itself, making future blockages more likely. Let the warm compresses coax the stye open on its own.
Avoid wearing contact lenses while the stye is active. Lenses can irritate the swollen area and introduce more bacteria. Eye makeup should also be skipped until the bump has fully resolved, and any products you were using before the stye appeared (mascara, eyeliner) should be replaced, since they may harbor bacteria.
When Antibiotics Help
Since most styes resolve within a week to 10 days with warm compresses alone, antibiotics aren’t always necessary. But if the stye isn’t improving after several days of consistent compress use, or if the redness and swelling are spreading beyond the bump itself, a doctor may prescribe an antibiotic ointment or drops to apply to the lid. For more significant infections, especially ones causing noticeable swelling across the entire eyelid, an oral antibiotic course may be appropriate. These decisions depend on how the infection looks in person, so a visit to your doctor or an eye care provider is the next step if home treatment stalls.
When a Stye Becomes a Chalazion
Sometimes an internal stye stops being painful but leaves behind a firm, painless lump in the eyelid. This is a chalazion, which happens when the gland stays blocked even after the acute infection fades. The lump consists of trapped oil and inflammatory tissue rather than active infection, so antibiotics won’t help.
Small chalazia often shrink over several weeks with continued warm compresses. If one persists for more than one to two months, or if it’s large enough to press on your eye and blur your vision, a minor office procedure can remove it. The doctor numbs the eyelid with a local anesthetic, makes a small incision (usually from the inside of the lid so there’s no visible scar), drains the contents, and clears out the material. The whole process takes about 15 to 20 minutes, typically requires no stitches, and recovery is fast.
Signs That Need Prompt Attention
Rarely, an eyelid infection can spread to the surrounding tissue. Watch for these warning signs, which suggest the infection has moved beyond the original stye:
- Increasing redness and swelling that spreads across the entire eyelid or to the skin around the eye
- Fever alongside the eye swelling
- Pain when moving the eye, not just when touching the lid
- Changes in vision, including blurriness or double vision
- The eye pushing forward or appearing to bulge compared to the other side
These can indicate a deeper infection of the tissue around the eye socket, which requires prompt treatment. The combination of fever, eye pain with movement, and reduced vision is especially important to take seriously.
Preventing Internal Styes From Coming Back
If you’ve had one internal stye, you’re more likely to get another, because the underlying issue is often chronic sluggishness in those oil glands. A daily eyelid hygiene routine can make a real difference. The approach is straightforward: apply a warm compress for 5 to 10 minutes once or twice a day, then gently clean the lid margins with a dedicated eyelid scrub or diluted baby shampoo on a cotton pad. This keeps the gland openings clear and the oil flowing normally.
People with oily skin, rosacea, or dandruff-related skin conditions tend to get more gland blockages. Managing those conditions helps reduce stye recurrence. If you wear eye makeup daily, remove it completely every night with an oil-free remover, and replace mascara and liquid liner every three months to limit bacterial buildup.
