Old scars can be tricky to treat. We lose collagen as we age, no amount of collagen inducing therapies can replace for example 1ml of fillers. But it's a great place to slowly start from (retinoids, alpha hydroxy acids (AHA) and later or maybe TCA).
Find a good dermatologist, if they suggest laser, which can be useful, leave that to the end. We want to fill the holes first.

Where are you located? How much downtime you can affort and your budget plays a role aswell.
Im sure others will give you good information, this is just my opinion, not an expert on your skin.

Have a goodd day

Find a plastic surgeons office with a staff thatspecializes in scar revision and skin rejuvenation.

Standard microneedling alone is not going to be the bestif you're seeking stunning visual changes in old acne scars.

I'm not a fan of the lasers so I usually prefer RF microneedling and/or medium depth chemical peels. I'm ahuge fan of rf so that's my position on any problem areas.Its used on elderly patients for wrinkle reduction so I wouldn't count it out based onage

thank you for the responses! Ilive in Berlin, Germany, but from the US. It is cheaper here to treat it, and I will go back for my third treatment of Resurfix laser with PRP on Friday. I so far see no improvement, but my dermatologist thinks I'll need 4-5 treatments. I'm not wanting to throw my money away, and hoping it'll at least increase collagen, and reduce pore size if it can't get rid of the scars. I can't afford a long down time, and the good thing about this treatment is that I'm red for a few hours, then pretty much back to normal the next day. My dermatologist says that this is more effective than microneedling, but it seems everyone has a different take on this..
