Most skin cysts are harmless and don’t technically need treatment, but the only way to permanently get rid of one is to have the entire cyst, including its inner lining, surgically removed. Draining a cyst, applying warm compresses, or getting steroid injections can help manage symptoms, but without removing that lining (called the cyst wall or sac), the cyst will almost always refill and come back.
What a Skin Cyst Actually Is
The lump you’re feeling under your skin is most likely an epidermoid cyst, a small, enclosed pocket filled with a protein called keratin. These are the most common type of skin cyst, and they show up most often on the face, neck, and trunk, though they can appear virtually anywhere on the body. The term “sebaceous cyst” gets thrown around a lot, but it’s technically a misnomer. True sebaceous cysts involving oil glands are rare. What most people call a sebaceous cyst is actually an epidermoid cyst.
The key thing to understand about these cysts is their structure. They have an outer wall, or capsule, that produces and traps material inside. That wall is why cysts keep growing and why they come back after simple drainage. As long as the wall remains intact under your skin, it will continue producing material and the lump will return.
What You Can Do at Home
If your cyst is small, painless, and not bothering you, you can leave it alone. Many people live with small cysts for years without any problems. But if a cyst is inflamed, tender, or swollen, warm compresses are the most effective thing you can do at home. Soak a clean cloth in warm water, wring it out, and hold it against the cyst for 5 to 10 minutes. Repeat this 3 to 4 times a day. The warmth increases blood flow to the area, reduces inflammation, and can sometimes encourage the cyst to drain on its own.
What you should absolutely not do is squeeze, pop, or try to cut open a cyst yourself. Unlike a pimple, a cyst sits deeper under the skin. Squeezing it can push its contents deeper into surrounding tissue, causing intense inflammation, or introduce bacteria and trigger an infection. Home “surgery” with needles or blades carries the same risks, plus scarring.
How Doctors Remove Cysts
There are two main approaches a doctor will use, and the distinction between them matters a lot for whether your cyst comes back.
Drainage (incision and drainage): Your doctor makes a small cut, then squeezes or suctions out the cyst’s contents. This is quick and provides immediate relief, especially for infected or painful cysts. But it’s not a permanent fix. The cyst wall stays in place, so the cyst typically refills over weeks or months.
Surgical excision: Your doctor removes the entire cyst, including the wall, through a small incision under local anesthesia. This is an outpatient procedure that usually takes 20 to 30 minutes. The incision is closed with stitches, and because the entire structure is gone, recurrence rates are significantly lower. When a cyst does come back after excision, it’s usually because a small fragment of the wall was left behind.
For most people who want a cyst gone for good, surgical excision is the recommended route. Your doctor may opt for drainage first if the cyst is actively infected, then schedule a full excision once the infection clears.
Steroid Injections for Inflamed Cysts
If your cyst is red, swollen, and painful but not infected, your doctor may offer a steroid injection directly into the cyst. The steroid reduces inflammation quickly, often flattening the cyst within days. This approach is particularly common for large, inflamed cysts where immediate surgery isn’t ideal because operating on inflamed tissue increases the risk of complications and scarring.
Steroid injections are a symptom management tool, not a cure. The cyst wall remains, so the cyst can return. There are also some risks: if too much steroid is injected or it’s placed too superficially, it can cause skin thinning, depressed scars, or lightening of the skin (especially noticeable in people with darker skin tones). For this reason, these injections are typically performed by a dermatologist with experience in the technique.
Signs Your Cyst Needs Medical Attention
A cyst that’s been sitting quietly under your skin for months doesn’t need urgent care. But certain changes signal that it’s time to see a doctor sooner rather than later:
- Infection: The skin over the cyst becomes red, warm, swollen, and painful. You may notice thick or discolored drainage.
- Rupture: The cyst breaks open under the skin, causing sudden pain, swelling, redness, and sometimes a foul-smelling yellowish discharge.
- Rapid growth: A cyst that suddenly gets much bigger over a short period warrants evaluation.
- Ulceration: The skin over the cyst breaks down or develops an open sore.
- Solid areas: If the lump feels hard or solid rather than somewhat movable and fluid-filled, your doctor may want to examine it more closely.
Rapid growth, ulceration, and solid areas within a cyst are red flags that raise suspicion for something other than a benign cyst. In these cases, your doctor will likely send the removed tissue for analysis under a microscope to rule out anything more serious. This is routine and doesn’t mean you have cancer, but it’s an important reason not to ignore a cyst that’s changing.
What Recovery Looks Like After Excision
Cyst excision is a minor procedure, but you’ll still have a healing wound. You’ll leave with stitches and a small bandage. Most people return to normal activities within a day or two, though you’ll want to avoid strenuous exercise or anything that stretches the skin around the wound for about a week.
Keep the area clean and dry, and follow your doctor’s instructions on bandage changes. Stitches are typically removed within 7 to 14 days, depending on the location. Cysts on the face heal faster than those on the back or chest, where the skin is thicker and under more tension. You’ll be left with a small scar, the size of which depends on how large the cyst was. Over time, most scars fade considerably.
Why Cysts Come Back
If you’ve had a cyst drained and it returned, you’re not imagining things, and it’s not unusual. Drainage addresses the contents but leaves the factory intact. Even after surgical excision, recurrence is possible if any fragment of the cyst wall remains. A skilled surgeon will inspect the removed cyst to confirm the wall came out in one piece, which is why excision of an inflamed or previously infected cyst can be trickier: inflammation makes the wall more fragile and prone to tearing.
If you have a cyst that keeps coming back, the best approach is a complete excision when the cyst is calm, not inflamed, and not infected. This gives the surgeon the clearest view and the best chance of removing every trace of the wall in one piece.
