I just wanted to pass along something that might help others. Castor oil has worked like magic on mine. I just put a thick coating of it on the
area at night. ...
I have done some research online since this time and I cannot find anyone else who has had success using castor oil.. Before the castor oil, I had gotten off biotin and birth control, so my results may have been a product of everything...
I just had to put it on my upper lip. I mostly sleep on my back, but when I turned over, I put my arm under my pillow and positioned my head in a way so that part of my face didn't touch the fabric.
I saw a difference after just one night.
