I have a light seborrheic dermatitis on my forehead and cheeks. what is a good over the counter treatment to fight the scaling and to reduce the redness from it.

Seborrheic: For your face and cheeks as opposed to your scalp like most people deal with, I would suggest you start with some OTC 1% hydrocortisone cream just on the affected areas twice a day until the lesions clear up and then stop the cream so your skin doesn't get used to the cream and have other issues as a reaction to chronic hydrocortisone use and then just use as needed.
