Those are stretch marks forming. Cocoa butter should help. I enjoy the feeling of new stretch marks forming. It's feedback to tell me that I am indeed getting fatter.
My wife has gained 30 Lbs. in the past year. She doesn't seem to get stretch marks very easily but a few months ago I noticed on her lower back and love handles that she has some very tiny bumps mostly to the touch but not very visible.....can these be related to weight gain?
