Since you have had the cyst on the face, to have minimal scarring of the area, we can follow minimally invasive procedure of surgical excision. The advantage of surgical excision is that the cyst is treated in one session. What happens is that the tissue immediately surrounding the sebaceous cyst is injected with a local anaesthetic. The cyst is incised and the contents squeezed out leaving the empty wall of the cyst. This can then be removed entirely through much smaller incision.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
