I'm 6wks pp (as of yesterday) and my linea negra is still as dark as ever. I don't believe it's faded at all. I also noticed that I have this weird discoloration right under my belly button, it's almost like my skin looks dirty or something. No clue what that is, but I really wish it would go away.
How long did it take for you ladies? And did you have any skin discoloration on your tummy (besides the linea negra)?
Mine didnt go away til i was like 3 or 4 months PP. Or longer. I dont remember exactly.*
I had my daughter in September of 2009, and I still have mine. It's faded, but it's there.
It took a good year for mine to fully fade.
Exfoliate a lot. It took mine a long time to go away with my first too. I never got one with my son...weirdness.
