Is there any certain treatment for sebaceous hyperplasia where it won't return?

These always come back although with lasers and desiccation its is less likely and microneedling helps too.  Best, Dr. Emer.

There are many different and effective ways to apply energy to this lesion and remove it effectively.  You will likely continue to have new one created that will need treatment with age.  Find an experienced physician in your area and discuss what treatment options they offer. 

Using a focused laser beam sebaceous hyperplasia can be permanently eliminated.  New lesion may occur over time in different spots, but those sebaceous lesions that are precisely eliminated will never return. 

Though I have access to co2, erbium, and 2 dozen lasers, simple desiccation with a pin point needle at a 1.2 watt setting can treat these lesions. The thing with seb hyperplasia is that they may recur (even in the same area), or new ones may form- this lesion is benign and a 'barnacle on the ship of life'- comes with older (wiser), age. Never the less, a super easy lesion to treat with minimal cost- tech involved. Dr Davin Lim, Brisbane. Australia.
