discolouration on upper lip - any advice? reasons?

[ratbunny]

because it looks like I still have a 'tashe but I have waxed it off. basically parts of my upper lip are darker than the rest. one bit is very pale. It has been like this (or I have noticed it) for a few months.
I have scrubbed it, wo its def not dirt!
I dont wear make up, so concealer / foundation is not a solution.
does anyone have any ideas?

It's not dirt, it sounds like you have what I have, chloasma. Apparently caused by hormones, there was a similar thread recently here

my friend has this problem, stay out of the sun as much as poss, use make-up with a high spf - my friend does this and it helps although does not fully eiradiacte (sp?) the problem
