Hi, I'm Tina. 28 yo. 2 years ago I moved from Bangladesh to US (Bay area). But after moving here I found my skin becoming darker and darker (3-4 shades darker than it was). Also some areas of my face is darker than others. I don't expose to sun at all. Is there any possibilities my body is producing more Melanie in US? What would your suggestions to have my skin tone back. An interesting fact is when I go back to Bangladesh for trip I get my skin tone back within a week or so. Thanks in advance for help!
