as someone posted above, red deep purplish stretch marks will usually fade to the "white hard to see kind." i remember almost a year ago when i first started getting them really bad on my left bicep, im talking when i would be curling it would look like i had nasty road rash. of course i only had it on my left arm. now, they have faded to white and are tough to see but, lucky as i am, im starting to get the same thing on my right arm...it never fucking ends i swear to god.
