MELASMA. After I had her it stayed. Everything I read said it would go away. I went to a dermatologist who suggested that since I was still nursing, that was why it was still there. After I stopped nursing her it slowly faded and went away.
So since I knew I was prone to Melasma, I wore a hat anytime I went outside when I was pregnant with Max. I got the dark patches again anyways. Only worse. I nursed Max for 2 years. After I stopped, they never went away. I still have it. I've used a Mary Kay product that has lighten them, but I obviously need something stronger. In the last 4 years I very, very rarely leave the house without a hat on. The only hats we have had, have been baseball hats. Which still allow the sun on your face more than I would like. So the answer is this $2 hat from Target. We are going to become best friends this hat and I.
