Best way to flat small scars? 3mm scars (Photo)

Hi, I’m still struggling with the scars from a laser mole removal procedure already 10 years ago. While I know complete removal might not be possible, even just the flattening the scars would make a huge difference in my self-esteem. And the flattening/smoothing of the scars doesn’t seem something impossible to reach. However, its been really tough to find solutions for this. I’ve been researching options, such as punch excision, ultra fractional CO2 laser, surgical CO2 laser, microplasma radiofrequency, microcoring, dermabrasion, ablative non-fractional laser, cryotherapy, steroid injection and Ellman Surgitron. But not sure which could work best or if some other option. I’m hoping you could provide some guidance on which treatments might be worth considering. Thank you so much!
