Most internal styes clear up on their own within one to two weeks with consistent warm compress treatment. Unlike external styes that form along the lash line, an internal stye develops deeper inside the eyelid, in the oil-producing meibomian glands embedded in the eyelid’s firm tissue (called the tarsal plate). Because of this deeper location, internal styes can be more painful and slower to resolve, but the core treatment approach is straightforward.
What Causes an Internal Stye
An internal stye starts when one of the meibomian glands on the inner surface of your eyelid gets blocked. These glands produce the oily layer of your tear film, and when debris, thickened oil, or inflammation plugs the duct, bacteria colonize the trapped material. In 90% to 95% of cases, the culprit is Staphylococcus aureus, a common skin bacterium. The combination of blockage and bacterial growth triggers a small abscess: a localized pocket of infection that causes redness, swelling, and tenderness on the inner eyelid.
You’ll typically notice the bump developing over a few days. When you gently pull down (or flip) your eyelid, you may see a small raised area or yellowish spot on the inner surface. The swelling can make your whole eyelid feel puffy, and blinking may be uncomfortable.
Warm Compresses Are the Primary Treatment
Warm compresses are the single most effective home treatment. The heat softens the hardened oil blocking the gland, increases blood flow to the area, and encourages the stye to drain on its own. Use a clean washcloth soaked in warm water (comfortably hot, not scalding) or a microwavable eye mask designed for this purpose. Apply it to your closed eyelid for 10 to 15 minutes at a time, three to four times per day.
Reheating matters. A washcloth cools quickly, so re-soak it every few minutes to maintain consistent warmth. Microwavable bead masks hold heat longer and can make sessions easier to stick with. After each compress session, you can gently massage the eyelid with clean fingers, using light circular or downward strokes toward the lash line. This helps push trapped material toward the gland opening.
Most styes begin improving noticeably within a few days of consistent warm compress use and fully resolve within one to two weeks. The key word is consistent. Skipping sessions or cutting them short slows progress significantly.
Keep Your Eyelids Clean
Lid hygiene supports healing and helps prevent the stye from worsening or recurring. After warm compresses, gently clean the eyelid margin with a mild cleanser. Diluted baby shampoo on a cotton pad works well. Commercial lid scrub pads and foams are also available, many containing low-concentration hypochlorous acid, which is particularly effective against Staphylococcus aureus and helps remove bacterial buildup from the skin without irritation.
Tea tree oil-based lid wipes (typically at 5% concentration) are another option, especially if you deal with recurring eyelid issues. Tea tree oil has antibacterial, anti-inflammatory, and antiparasitic properties that can help manage underlying conditions like meibomian gland dysfunction, which makes internal styes more likely in the first place. Lower-concentration formulas (around 0.02%) are gentler on sensitive skin but may be less effective for stubborn problems.
What Not to Do
Do not squeeze, pop, or try to lance an internal stye yourself. Because these styes sit deep in the eyelid tissue, attempting to drain one at home risks pushing the infection deeper or spreading bacteria to surrounding tissue. Let it drain naturally or have a doctor handle it.
Avoid wearing contact lenses while you have an active internal stye. The lens can irritate the already inflamed tissue, trap bacteria against your eye, and slow healing. Switch to glasses until the infection has fully resolved. Similarly, skip eye makeup during the infection. Mascara, eyeliner, and eyeshadow can introduce more bacteria to the area and contaminate your products, setting you up for reinfection later. Once the stye is gone, replace any eye cosmetics you used in the days before the stye appeared.
When You Need Medical Treatment
If your internal stye hasn’t improved after about a week of consistent warm compresses, or if it’s getting larger or more painful, it’s time to see an eye doctor. At that point, the stye may need prescription antibiotic eye drops or ointment to fight the bacterial infection more aggressively. For styes that are especially large, persistent, or associated with significant surrounding skin infection, oral antibiotics may be prescribed.
A stye that doesn’t drain on its own after several weeks may need a minor in-office procedure called incision and drainage. Your doctor numbs the area with local anesthetic, then makes a small cut on the inner surface of the eyelid to release the trapped material. The procedure takes just a few minutes and typically provides immediate relief from pressure and pain. Recovery is quick, though mild soreness and swelling may last a day or two.
Internal Stye vs. Chalazion
During the first couple of days, an internal stye and a chalazion can look identical. Both involve a bump in the eyelid related to a blocked meibomian gland. The difference becomes clear over time. A stye stays painful, red, and tender because it’s an active infection. A chalazion, on the other hand, transitions into a firm, painless nodule in the center of the eyelid as the acute inflammation fades but the blocked material remains.
Chalazia typically absorb on their own within two to eight weeks. If your once-painful bump stops hurting but doesn’t go away, it has likely transitioned into a chalazion. Warm compresses still help. Persistent chalazia that don’t respond to treatment over several months may need to be biopsied to rule out other causes.
Warning Signs of a Spreading Infection
Internal styes rarely cause serious complications, but because they sit close to the eye socket, infection can occasionally spread to the surrounding tissue. Watch for these red flags: rapidly increasing swelling that extends beyond the eyelid to the cheek or brow, fever or chills, eye pain (not just eyelid tenderness), changes in vision, or difficulty moving the eye. These symptoms can indicate a deeper tissue infection that, without prompt treatment, may lead to vision impairment or more serious complications involving the brain and sinuses. If you notice any of these, seek urgent medical care.
Reducing Your Risk of Recurrence
Some people get internal styes repeatedly, often because of chronic meibomian gland dysfunction where the oil glands tend to produce thicker secretions that clog easily. Daily lid hygiene is the most effective prevention strategy. A quick eyelid cleaning each morning or evening, using a gentle lid scrub or diluted cleanser, keeps bacterial levels low and gland openings clear.
Periodic warm compresses (even when you don’t have a stye) help keep meibomian gland secretions flowing smoothly. A few minutes of warmth two to three times per week can make a noticeable difference if you’re prone to blockages. Wash your hands before touching your eyes, replace eye makeup every three to six months, and clean contact lenses properly to minimize the bacterial load near your eyelids.
