It could be from blowing your nose or your nose running. Try using softer tissues, and try exfoliating your face including under your nose to get rid of dry skin- don't forget to moisturize too!
but i never have the need to blow my nose , and the only tume my nose runs is when im crying . its always there and i have no idea why ! its always been there ...
Alright, then just try the exfoliation thing. Exfoliating your skin rubs off all of the excess dry skin and might solve your problem.
It could be from extreme weather, you should try oils and lotions.
