Could castor oil potentially help in getting rid of sebaceous cysts?

Particularly found in individuals suffering from cystic or nodular acne, sebaceous cysts present as a hard, rounded lump under the skin, which can measure up to 5 cm. As their name suggests, the formation of sebaceous cysts is closely linked to the hair and sebaceous follicles and results from a rupture of these structures, due to an accumulation of sebum or keratin. They are most commonly found on the scalp, ears, and upper arms, although they can be present on other parts of the body. Initially benign, cysts can become infected if they are handled or pierced. They then turn red and painful and can fill with pus. Although some non-infected cysts may resolve on their own, dermatological intervention may sometimes be necessary to remove them.

Despite its numerous benefits for the skin, the castor oil does not appear to have any effect on sebaceous cysts and there is no scientific evidence to support this claim.

The only way to remove a sebaceous cyst that does not disappear on its own is to consult a dermatological surgeon. If the cyst is neither infected nor in an inflammatory stage, it can be directly removed. The surgical procedure generally lasts between 15 and 20 minutes. It can be performed either in a dermatology office or in an operating room. This intervention requires local anesthesia and the patient can then resume their activities. It should be noted that the removal of a cyst almost always leaves a scar on the skin that fades over time. In the case of an infected cyst, antibiotics are prescribed. Once the infection is contained, the operation can be performed.

Note : Using castor oil, known for its anti-inflammatory properties, on an inflamed cyst is a misguided idea. Indeed, castor oil has a rather greasy texture and requires application through massage to properly penetrate the skin. However, it is strongly advised against touching a sebaceous cyst, especially when it is in an inflammatory phase, as this could cause an infection or worsen an existing one.

If you are unsure whether the lump under your skin is a benign sebaceous cyst, it is imperative to seek advice from a healthcare professional to rule out any risk of cancer.
