How long should a rubber band be on your keloid?

Keloid: If you're trying to flatten and smooth a keloid scar, a rubber band is ineffective. Applying topical silicone gel sheeting is the best treatment short of having the keloid surgically removed, injected with steroid and undergoing a short course of superficial radiation therapy.

Don't recommend: Keloid treatment is typically done with multiple modalities including compression, injection therapy, surgical resection, laser treatment and radiation.

Rubber band?: Why is it on there at all? Keloids can be injected with steroids or removed formally a a Dermatologist if need be.
