My dirty neck faded when I started metformin. I have the large skin tags frozen off ... the smaller ones hurt too much but if anyone knows how to get rid of them please help they are embarrassing on my thighs and eyelids. I have a patch of AN on my abdomen but silly me didn't know what it was until i read this thread LOL. It has faded significantly since starting Atkins 6 weeks ago but the texture remains. It's a small patch and the least of my worries since my belly is beyond bikinidom.
