I got stretch marks right above my arm pits from lifting, I know they don't go away but does anyone know a good way to keep them from progressing besides cocoa butter? I've read that you get stretch marks from a lack of vitamin E and callogen in your skin, anyway besides lotion to get callogen?

reason being cocoa butter use over about a week, makes my skin irritated

also, i never got stretch marks until i was 21 years old, got big in high school, nothing, grew 5 inches in a year and added 35 lbs, nothing, anyone know why now?
