so are you wanting to do a long term low dose or?
Yep same thing happened to me, dry lips and skin peeling off rapidly on them.
As you deeper into your tane journey yourll notice that the nivea chapstick wont do much, so pick up one called blistex intensive lip balm (think its something like that). works so well. When my lips have cracked and are bleeding, its been the only thing to heal it completely up. i'd also advise against using sudocrem now. Just stick with gentle wash and moisturiser and the accutane. ps have you given the cleansing with moisturiser a go yet?
Why going to sleep at 8pm? because of the aching?
Keep going, doing great.
