Can I expect same or better results with Excel V compared to VBeam laser for old PIE acne scars?

Hello FF.  For the type of red scars you have, the Vbeam would be more appropriate.  The wavelength of light for diffuse redness like you have is more appropriate for the Vbeam.  If you are looking to revise the texture of the skin, then a fractional laser would be more appropriate and neither laser you mentioned would help.  

Vbeam laser is the gold standard for deeply red or pinkish hyperemia on the skin from skin trauma or surgery. We use this laser quite often to improve redness in combination with Plato’s Scar Serum twice daily. Options for red scars include scar modulation, intralesional injections to reduce inflammation, vbeam laser, and IPL treatment. Many sessions are required which is why you should schedule with a trained clinician familiar with scar treatment and Vbeam pulsed dye laser.

Acne scars need a combination approach for long-term improvement. For redness or thick acne scars, we use a combination of vascular lasers like Yellow laser, Aerolase, excel V, and/or IPL. All lasers are combined with microneedling/PRP to improve the results and accelerate your healing time. Most people have various types of scars, so we create a tailored treatment plan for each patient. We also use:- Injectable fillers like Bellafill and Sculptra (with or without subcision) for atrophic, indented scars. - Subcision for depressed, tethered scars. - Lasers such as Fraxel, Erbium, CO2 or fractional radiofrequency (Venus Viva, Skinfinity, Intensif microneedling RF) for textural issues and superficial scarring. - TCA CROSS and punch excision for deep ice pick scars and narrow box car scars.Keep in mind that a personalized combination treatment by an expert physician will give you the improvement you're looking for. I recommend getting a formal evaluation with an experienced cosmetic dermatologist and acne scarring expert. Best, Dr. Emer.
