Why is the skin tone around my mouth lighter?

The skin tone around my mouth is lighter than the rest of my face. This means that I have to use a lot of concealer. Any ideas why and what I can do to change it would be appreciated.|||mines a little darker|||I think everybodys is like that.|||It probably isn%26#039;t as noticeable to everyone else as it is to you. If it%26#039;s really noticeable, try some bronzer or some sort of tanning cream.
