My inner thighs, vaginal area and armpit got darker when I got pregnant with my babies, also because I have diabetes type
2 when i turned 30, but my blood
sugar are controlled. I am slightly over weight however the dark inner thighs is not the cause of the darkening, it was caused by hormone changes. Being clean is not the issue either, I take a shower everyday. So, I'll tell you all my secret on how I got rid of them.
