Venus Viva vs Fraxel? I have lot of acne scars, enlarged pores, small scars on face. Consultation didn't do any face scanning

You will need much more than a few treatments of viva or fraxel to treat severe scars.  I do fraxel on myself every 3 months just to maintain improvement in my skin.  You will need a formal consultation with an acne scarring specialist.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 personally have Venus Viva and a fractionated RF device (Fractora) in my office. I sincerely believe that Fractora is superior to Fraxel and if done by an expert at high energy, can improve your acne scarring in 1-2 treatments. I've done thousands of these treatments in my office and absolutely without question would not think you would be happy with Viva as the treatment depth is just not enough to get deeper acne scarring. "This answer has been solicited without seeing this patient and cannot be held as true medical advice, but only opinion.
