years ago i made the mistake of going on an acutane equivalent
then i did mistake inception and went out in sun for long periods of time in summer
i ended up burning off like 50 layers of skin (and i am not one to normally burn at all). took months to heal. it was crazy
years later it is still prone to getting red and sunburnt even from minimal sun exposure (wheras rest of body does not burn, ever)
what can i do to strengthen, heal, avoid nose cancer, etc?
