I have had Sebaceous Hyperplasia for over 15 years. The doctor told me I had to have them removed in the office, but that insurance wouldn't pay for it because it was deemed a "cosmetic" procedure.
For the last three months (due to "cranky" skin), I use tea tree oil - very diluted with water - after I wash my face. I follow up with coconut oil for moisturizer. The unexpected side effect? My sebaceous hyperplasia is gone.
