nail polish remover

i was trying to remove my nail polish but then my finger tips always got cracked. I dunno why.  I may have sensitive skin but i don't know what else i can use.  It's been my problem every time i use nail polish remover...sigh~ Any good brand can suggest me?

Thanks!

By the way, I'll make appointment to see dentist soon.  I am so scared already. Because i have to remove some of my tooth and it sounds scary.....umm! Well, i hope after 2 years, my teeth will be nice and white, hehe! wish me luck!
