Once the skin is prepped, the dermatologist injects a local anesthetic—typically lidocaine—directly around and beneath the cyst. This numbing agent works quickly, ensuring that you feel no pain during the drainage, though you may still feel some mild pressure or tugging. ## Making the Incision Once the area is completely numb, the dermatologist selects the most appropriate surgical approach based on the size and location of the cyst. There are two primary methods used to access the cyst: * **Conventional Incision:** The dermatologist uses a scalpel to make a single linear cut across the center of the cyst. This method is often used for larger cysts to allow for easy access to the contents and the sac. * **Minimal Excision (Punch Biopsy):** The dermatologist uses a small, circular tool to punch a tiny hole in the center of the cyst. This technique leaves a much smaller scar and is preferred for highly visible areas like the face or neck.
## Draining the Keratin and Sebum After making the incision, the dermatologist applies gentle, controlled pressure to the sides of the cyst. This causes the trapped contents—primarily keratin (a protein that makes up skin, hair, and nails) and sebum (skin oil)—to express through the opening. Because the contents of a sebaceous cyst are often thick, cheesy, and white or yellowish, this step is frequently referred to as the "satisfying" part of the drainage. The dermatologist carefully wipes away the material and cleanses the area as the cyst empties. ## Extracting the Cyst Capsule
Draining the fluid and keratin is only a temporary fix. The most crucial part of a professional cyst removal is the extraction of the cyst wall, also known as the capsule. The capsule is the sac that holds the keratin; if any part of this lining is left behind, the cyst will eventually fill back up with fluid. Using surgical forceps and scissors, the dermatologist carefully dissects the capsule away from the surrounding tissue. They gently pull the entire sac out through the incision. Seeing the intact sac successfully removed is the ultimate goal of the procedure, as it signifies that the cyst is highly unlikely to return. ## Wound Closure and Recovery Once the cyst capsule is fully removed, the dermatologist cleanses the empty cavity with sterile saline to wash away any remaining debris. Depending on the size of the incision, the wound is managed in one of two ways:
* **Sutures:** For larger incisions, the dermatologist will close the skin with stitches to promote optimal healing and minimize scarring. * **Natural Healing:** Small punch incisions are often left open to heal from the inside out, which reduces the risk of trapped bacteria. The dermatologist then applies a sterile dressing or bandage and provides detailed aftercare instructions, which typically include keeping the area clean and dry for the first 24 to 48 hours. ## Why Professional Extraction Matters It can be tempting to try to squeeze or pop a cyst at home, but doing so carries significant risks. Attempting a DIY drainage often ruptures the cyst wall beneath the skin rather than expressing it outward. This forces the keratin and bacteria into the surrounding tissue, leading to severe inflammation, painful infections, and a much higher likelihood of scarring.
Furthermore, without professional surgical tools, it is virtually impossible to remove the cyst capsule at home, meaning the bump will almost certainly regrow.
