Is Mixto Fractional CO2 Laser Effective for Acne Scars?

Fractional CO2 laser such as Mixto, Total Fx, Fraxel Repair delivers CO2 laser energy via pixelated fashion where effective resurfacing and collagen remodeling can take place with typically one week of downtime. However, moderate to severe acne scarring may benefit from punch excision of ice-pick scarring ahead of time and multiple treatments may be necessary 4-6 months apart for severe acne scarring or for ethnic skin where the energy and penetration of the laser cannot be too aggressive to minimize post-treatment pigmentation.

Mixto fractional laser resurfacing works beautifully to help reduce scarring caused by acne. This CO2 (carbon dioxide) laser helps to deliver a precise matrix of Microspots that penetrate to the dermis and stimulate the formation of new collagen. At the same time, immediate shrinkage of damaged tissue is achieved.
The Mixto improves pigmentation problems, reduces pore size appearance, wrinkles, acne scars, and other textural irregularities. The laser has an additive effect and many patients will notice greater improvement when they have multiple sessions.
Compared to traditional skin resurfacing, clients experience less downtime and are more comfortable during the procedure. It is unlikely that anyone procedure will completely smooth the skin from acne scars but my patients have noticed an improvement ranging from 30-60 %.

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.
