Most cysts under the skin are benign, slow-growing lumps that won’t go away on their own. The only way to permanently get rid of one is surgical removal of the entire cyst, including its outer wall. But depending on the size, location, and whether it’s causing problems, you have several options ranging from home care to a quick in-office procedure.
What That Lump Actually Is
The vast majority of cysts that form just beneath the skin are epidermoid cysts, sometimes still called sebaceous cysts. They develop when skin cells that normally shed from the surface instead move deeper and multiply, forming a small sac that fills with a thick, yellowish material called keratin. You’ll typically feel a firm, round bump that moves slightly when you press on it. They’re most common on the face, neck, scalp, and trunk, and they can range from pea-sized to several centimeters across.
Pilar cysts are a related type that form specifically around hair follicles, most often on the scalp. They feel similar to epidermoid cysts but tend to have a smoother surface. Both types are harmless on their own, but they can become inflamed or infected, which is usually what drives people to search for a solution.
What You Can Do at Home
If a cyst is small, painless, and not bothering you, the simplest option is to leave it alone. Many people live with small cysts for years without any issues.
If a cyst becomes tender, swollen, or inflamed, warm compresses are the most effective home treatment. Apply a warm, wet washcloth to the lump for 20 to 30 minutes, 3 to 4 times a day. You can also place a hot water bottle or heating pad over a damp towel. Keep the temperature comfortable, no hotter than bath water. This can help reduce inflammation and may encourage a cyst to drain on its own. It won’t eliminate the cyst permanently, but it can relieve discomfort while you decide on next steps.
Beyond warm compresses, keep the area clean with gentle soap and water. There are no creams, supplements, or topical treatments that dissolve cysts. Products marketed as “cyst drawing salves” lack clinical evidence for this use.
Why You Should Never Pop a Cyst
Squeezing, poking with a needle, or cutting into a cyst yourself is one of the worst things you can do. Unlike a pimple, a cyst sits deeper in the skin and is enclosed in a sac. Attempting to pop it pushes the contents into surrounding tissue, which can trigger a boil-like infection that spreads quickly and requires urgent treatment. Even if you manage to get some material out, you’ll leave the sac behind, and the cyst will refill.
Self-extraction also creates a high risk of scarring, often worse than the scar from a proper surgical removal. There is no known way to prevent epidermoid cysts from forming in the first place, but you can prevent infection and scarring by resisting the urge to squeeze or puncture them.
Medical Drainage: A Temporary Fix
If a cyst is infected or painfully swollen, a doctor may perform a simple drainage procedure. This is done in the office under local anesthetic, so you won’t feel pain. The provider makes a small cut in the skin, drains the fluid or material, then covers the site with gauze and a bandage. The whole process takes minutes.
Drainage provides fast relief, especially for infected cysts, but it’s not a permanent solution. Because the sac lining stays in place, the cyst will almost always refill over time. Think of drainage as a way to manage an acute problem, not a cure.
Surgical Removal: The Permanent Solution
The only way to get rid of a cyst for good is to surgically remove the entire structure, including the sac wall. This is also an in-office procedure performed under local anesthetic. The provider makes an incision based on the size of the cyst, removes the whole thing in one piece, then closes the skin with stitches and a bandage.
Because the sac is completely removed, there’s nothing left to refill. This makes full excision the standard recommendation for cysts that keep coming back, are cosmetically bothersome, or sit in areas where they get irritated by clothing or movement. The incision does leave a small scar, but it’s typically a thin line that fades significantly over several months.
What Recovery Looks Like
After drainage, recovery is straightforward. You’ll keep the area clean and covered for a few days, and any swelling or redness from infection should improve quickly, especially if antibiotics are prescribed alongside the procedure.
After surgical excision, you’ll have stitches that need to be kept clean and dry. Suture removal typically happens within one to two weeks, depending on the location and size of the incision. Most people return to normal activities within a day or two, though you’ll want to avoid strenuous activity that could stress the wound for about a week. Some mild soreness and swelling around the site is normal and resolves within days.
The area may feel firm or slightly raised for several weeks as the deeper tissue heals. Full tissue remodeling, where the scar softens and flattens, takes several months. Scars on the face tend to heal more neatly than those on the chest or back, where skin tension can widen a scar over time.
When a Cyst Needs Attention
A cyst that’s been sitting unchanged for months or years doesn’t require treatment unless it bothers you. But certain changes signal that it’s time to see a provider:
- Pain or tenderness that develops suddenly, especially with redness spreading outward from the bump
- Rapid growth over days or weeks
- Drainage of foul-smelling material, pus, or blood
- Skin discoloration or warmth over the cyst
These are signs of infection or rupture. A cyst that breaks open beneath the skin can cause a boil-like infection in the surrounding tissue, which may need antibiotics or urgent drainage. Infected cysts are also harder to remove cleanly, so doctors often prefer to treat the infection first and schedule excision after the inflammation settles, usually a few weeks later.
If you’re unsure whether a lump is a cyst or something else, a provider can usually tell by examining it. In rare cases where the diagnosis isn’t clear, an ultrasound or biopsy can confirm what’s going on beneath the surface.
