I have a indent in the side of my left nose bridge it really bothers me cause it looks like a dark mark. (photo)

Thanks for your question and photo. Based on the one photo at that angle, it looks like there is narrowing/pinching on one side more than the other. More photos from the standard angles are needed and in person visit is even better to give you a solid opinion. However, I think non surgical rhinoplasty with filler may be a really good option for you if this your only concern. See a rhinoplasty doctor for an opinion. Good luck
