<s>[INST] i got alot of stretch marks , mostly on my legs though i know im not over weight but what could i do to make them less noticeable and keep them that way and what might be causing them? [/INST] Hi!, Welcome to Chat Doctor from, Stretch marks are difficult to treat .if they are extensive then rule out any hormonal problem...there are 3 diff types of stretch marks -white, black and red. So if it is black then try retinoid cream locally ... If it is white then you can go for lasers too... Othere wise there is a new technique which lot of doctors are trying is DERMAROLLER, which can even be tried. For prevention, you can use olive oil or it e oil locally. Take care, Chat Doctor.  </s>
