Some more..

I think it might just depend on your skin type and ethnic background. I'm part asian, so all my hyperpigmentation turns from red to brown. I haven't seen the white happen before, but a lot of people's skins react in different ways. Your skin looks pretty good, considering. If they really bother you, products to even out skin tone and fade spots will help with that.

It's the sun that has caused these pigments though.. They should probably disappear once my tan goes, right? At least the brown ones?
