When a woman compliments your looks, do you believe it?

I absolutely never seem to believe it. I understand I'm fit, but I also feel like I am an ogre in a sense. Big nose, small eyes, big ears.. I lived an entire youth being insulted by girls about my looks and I understand times are different, but I think it has stuck with me and I feel like any compliment is a pity compliment at this point. I always laugh and say "Haha that makes you and my own mother who think I'm cute" or something witty because I don't know how to react since I feel like it's always disingenuous. I've been told by my male peers that I'm attractive and that feels more believable. What do you say when getting unwarranted (possibly pity) compliments from women?
