I saw my dermatologist yesterday. He told me that if I wanted to increase it, I could do one day 10mg and the next day 20mg and then 10mg again..etc. He doesn't mind going slowly. The max dosage would be about 60mg for me. I have dry skin, dry lips and stiffness in my right wrist that makes it want to bend forward towards my wrist. Weird. That's basically it.
