Bio oil is good vitamin E works well too but if their old stretch marks its hard to get rid of them completely
Coconut oil or vitamin e oil help. I have a very big noticeable scar on my upper left arm and stretch marks on hips, both the coconut oil and vitamin e helped minimize the appearance of the scar and stretch marks.
Palmers cocobutter formula or naturessence cream work great. They help minimized the ones i have on my hips and i used palmers when i was pregnant..i have 4 kids and i have 3 strechmarks on my abdomen to show for it...i am still using both of them. Palmers during the cold weather and natureessence during the hot weather.
