Through research here on RealSelf I've confirmed that permanent change to the shape of the nostrils or nose (from picking or blowing) is highly unlikely - except if it is VERY excessive or frequent (etc.). So this I know. Still I've been squeezing the nose "back into shape" when I've noticed the nostrils being wider than usual. I'm left with the feeling that this shouldn't be necessary. However I can't convince myself about this. This is why i seek your advice. Thank you for your time, doc!
