I let the skin grow for several days until it peeled off on it's own. I still do not use any medication. It also seems that any chapstick but blistex is okay. My lips have not grown the hard skin in three days. They have peeled sparingly and in small pieces. I've been drinking lemon water for days. It's been over fifteen days of drinking lemon water. I'm still using the castor oil on my lips throughout the day and at night. I think I'm going to stick with the method.
I must also add that over the weekend, about 4 or 5 days ago, I was out in the sun for a while playing sports. I don't know if the sun affected my lips (other than a light tan) or not but for the days afterwards, they have been feeling better.
