Re; Bells Palsy and Keratosis pillars:
I was using castor oil on my face for Bells Palsy. I applied it on my face with cotton ball and covered my face with plastic on each side (left opening for nose so I could breath) then put a"moisture" heating pad that you warm in microwave over my face for 20 minutes every night. Can't be sure if it's helping my Bells Palsy but after literally years and years of going to doctors for kreatosis polaris and using suggested home remedies, the castor oil "completely" cured my Keratisis polaris within in a couple of weeks. I first noticed within a couple of days it was resolving. I've had the condition for at least 10 years.
