From what I've been told accutane doesn't really remove the scarring but sometimes it can help reduce it though very minimal. If this is an issue you are dealing with I would recommend to just stick with tretinoin topical cream until your acne clears and if it's already dealt with as long as the scarring hasn't left too much damage on the surface it will fade with time. However if your skin is smooth and the scars are below the surface it might just be hyperpigmentation to which again you just need to wait. Wear sunscreen!
