When I switched to Castor oil (hexane-free, organic), a few months ago, I could tell a big difference in that it took care of the dryness as well as the h/f issue!!
I use 1 drop under my upper eyelid & it coats the whole eyeball as it slides down. After a minute, I wipe the access that leaks out. I do this just before bed, and again in the morning - before & after my shower. To remove the heaviness of the oil off my face, I apply a small amount of coconut oil to moisturize. It does take 2-3 min to absorb.
