RESUMEN
BACKGROUND: Skin rejuvenation can be achieved with minimally invasive treatments using energy-based devices that feature reduced side effects and downtime. Post-treatment care is key to minimize any potential side effects and skin reactions such as erythema, dryness, or dyschromia. OBJECTIVE: The objective of this study was to evaluate the efficacy and patient satisfaction of a novel carboxytherapy gel mask compared with petroleum-based lanolin-containing ointment to accelerate wound healing facial post-nanofractional radiofrequency treatment. METHODS AND MATERIALS: Ten subjects were enrolled in this pilot, prospective, randomized, single-blind study and randomized into two arms. One arm received one nanofractional radiofrequency treatment with ointment right after and four consecutive days of ointment applications twice a day, while the second arm followed this regimen with a carboxytherapy gel mask application right after and four consecutive days after treatment. Investigator, safety, and patient assessments were conducted at 24 hours and one-week post treatment. Safety was monitored throughout. The primary endpoint was defined as the degree of investigator global assessment (IGA) in photodamage, pigmentation, and wrinkles using standardized photographs. Secondary endpoints included investigator-rated degree of erythema, edema, crusting, exudation, percentage healing, improvement of skin quality, and patient satisfaction. RESULTS: Nine patients completed the study. There was improvement of one degree in IGA for photodamage, pigmentation and wrinkles in all patients using the carboxytherapy gel mask at the one-week follow up. Blinded investigator ratings showed significant improvement of dryness, erythema, edema, crusting, and percentage healing at the 24-hour follow up, with all patients remaining the same a week post treatment. All patients in the carboxytherapy group were satisfied with the treatment and had no adverse effects. Three patients in the petroleum-based lanolin-containing group experienced mild edema and acne breakout that resolved two weeks after treatment. CONCLUSION: Carboxytherapy delivered via a gel mask after skin rejuvenation procedures is a safe and effective strategy to improve clinical outcomes and reduce post-treatment side effects.
