The "walls" of your scars are pretty distinct, so I'm betting that's why you're not seeing the results you'd like to see from needling and laser. More sessions usually do produce more results, but I suspect you might be right that another course of action might be best.

However, I'd say the very first thing to consider in your case is making sure you don't make it worse. The main scar I can notice is the one between your eyes and you want to make sure you don't make that one any worse. I would worry that excision (which I think is what you mean by scar revision surgery?) could make it look worse if it doesn't go well. But, please keep in mind that I am not the expert in that. I'm just using my common sense.

Regarding fat grafting, I can see why you are thinking about that. But again, it makes me nervous. If you do something like that, just proceed with the utmost caution. Remember that this is your skin, your face, and your life. Be your own advocate and move forward only once you are feeling so absolutely confident that you are in really good hands.

If you do get anything more done, please share results with us.

And lastly, remember that we see our own imperfections more than other people do. You always have the option of just accepting your imperfections, which we all have.
