Let me start by saying, I've been fortunate for 32 years that I've never experienced this so don't know if it's hormone related after having my baby 7 weeks ago or if its the sun, but over the last two weeks the skin on my upper lip has gone dark and makes me look like I have a mustache!!! I'm using lightening creams galore but can anyone advise if they've had this before what they use to get rid of it or best concealers to use to hide it for the foreseeable?! Desperate here!
