Melasma anyone?

Apparently at some point during pregnancy my body responded with a “hell yes” to this question!   Wondering what Melasma is?  Does the term “pregnancy mask” spark any type of recognition?  I read a little about this while I was pregnant but never looked into it.  I guess I really should have.  Two years later, after giving birth to Alivia, I have been battling with what I thought were age or sun spots when all this time it was Melasma!
