Can i have subcision done after having bellafill? (photo)

Based on this photo you will need much more than 1 CO2 laser treatment. You will need long term monthly laser treatments, micro needling RF, submission and fillers.  Fillers like Bellafill will take numerous treatments along with subcision.  If you did a co2 you should have done a non ablative laser like Fraxel or halo about 4-6 weeks later, every 6 weeks or so to really rebuild your skin.  Also, it appears you have some acne and need that treated as well with Isotretinoin, skin care, and facials.  You really need a full treatment plan, please see an expert.  
Acne scar treatment needs a combination approach for improvement.  For the best results, one should target the acne scar type.  As everyone has a unique pattern of acne scarring, the best solution is a tailored one.  Typically you need fillers like bellafill and sculptra for atrophic indented type scars with or without subcision.  Subcision for depressed tethered scars.  Vascular lasers like yellow laser, aerolase, excel V or IPL for redness or thick scars. And lasers such as fraxel, erbium, co2 or fractional radiofrequency like venus viva, skinfinity, intensif or fractora microneedling RF for textural issues and superficial scarring.  Deep ice pick scars and narrow box car scars are best treated with TCA CROSS and punch excision.  All lasers are combined with microneedling and PRP to get even better results and improve healing times.   The majority of patients will have a collection of different scar types, and hence a tailored treatment plan is needed by an expert physician.  It is never about the laser or product that gives the results, its about the expert behind the equipment that gets you the outcome.  Scars cannot be cured and will need life-long treatments to maintain and build on the results.  For those at high risk for hyperpigmentation (darker skin types or asian or hispanic or mixed ethnicities) we alreayd pre-treat the skin with cosmelan or enlighten lightening peels to prevent complications from energy-based or chemical-based treatments.  Best, Dr. Emer. 

I do this routinely and there is no reason to not perform subcision in this case. Sometimes I will inject Bellafill at the same time as subcision as well. Subcision is needed for tethered atrophic and rolling acne scars.

Thank you for your photo. It is possible to have multiple rounds of subcision with filler in order improve the appearance of your acne scars. I recommend waiting a minimum of 2 weeks between treatments to allow your skin to heal and for the inflammation to subside. Hope this helps!
