Sebaceous Cysts

People sometimes ask if there is anything can be done apart from surgery for these common cyst. Dr Jonathon Wright has found this treatment a treatment with SSKI (Saturated solution of potassium iodide) and DMSO (dimethylsulfoxide) will often clear sebaceous cysts in weeks to months. DMSO helps the iodine to be absorbed deeply. Mix one ounce of each – this will initially get quite hot but then cool down in a few minutes. Rub the mixture in vigorously twice daily. With persistence the cyst will break down. This will work with sebaceous cysts but not lipomas (fatty lumps which can look similar). It also helps with Dupuytren’s contracture and keloids where these can be rubbed in. It is worth monitoring thyroid function whilst using SSKI if treatment last more than a month or two.

However SSKI is difficult to obtain in the UK. I would expect that higher concentrations of Lugol’s iodine (5% Lugols contains contains 10% potassium iodide) would work in a similar way.

I have found this combination of Lugol’ iodine and DMSO has helped with small sebaceous cysts.
