Post Opers Questions

Hello all.... Well I have a question.  When I was fat and overweight I had the most clear complexion face.  My surgery was 4 years ago and I have brown patches on my cheek bones, a SPOT between my eye browns, small patches on my eye brows, and 2 small patches above my top lip.

Have any of you experienced this?  My boyfriend said it was from tanning.  My OBGYN called it Malasma and I have since spoken with other surgical patients that have said they have the same thing since surgery? 

So, if you have it please let me know if this is a defienciency in something, and what you have done or are doing to clear it up.  I have bought something from Clinique to lighten it up and it is not working. 

Thanks,,
Elizabeth
