I think if it really bothers you then you should think about going for a consultation in your area and see what the specialist think about what can be achieved. I personally think that extra caution should be taken when using lasers on skins with colour, so think carefully before going down the laser route, if this applies to you and make sure you see at least a couple of specialists before making your decision.
And remeber there are other options to laser for stretch marks although I think it will be difficult to completely fade them but hopefully you should be able to improve on them. Do some research on line on what else you can do and maybe someone on this board who may be in a similar position may be able to recommend something that has worked for them.
