Acne scar removal - what is the best treatment? (Photo)

I'm sorry that you have been so disappointed with your treatments to date. I am not surprised, however, that you have not had satisfaction with your prior treatments. For one thing, miicroneedling treatments are best reserved for a final "polishing step" once other more appropriate treatments have been done. It is not particularly effective as a first-line treatment. Besides, I have cautioning my regular followers for years to exercise a great deal of "buyer beware" caution when being hawked RF microneedling treatments even for the polishing step because RF simply adds to the expense and to the risks. Sorry.
Regarding subcision, at least from the photos provided, there appear to be a significant number of ice pick scars for which TCA CROSS, not subcision, would be the treatment of choice. A Field Subcision, on the other hand, of the cheeks might have been a far more successful initial approach.
You would be wise going forward to consult with a board certified cosmetic dermatologist acne scar specialist and best of luck.

Acne scar treatments require precision and attention to detail. There are several types of acne scars, including atrophic, hypertrophic, PIH hyperpigmented, and hypopigmented scars. Depending on the types of scars you have, our office can recommend a Hidef treatment protocol that can recontour existing scars and reduce complexion irregularities. The results are simply life-changing.

As a general rule, we recommend fillers, subcision, acne surgery, RF ablation, and laser ablation to help with atrophic scars. Hypertrophic and keloid acne scars require pulsed dye laser and IIT SC. PIH scars require chemical peels, Melarase creams (AM and PM) and laser.
If you have ice-pick scars, we recommend RF ablation and TCA Cross.
Best,
