Efficacy and Tolerability of a Procedure Enhancement System with TriHex Technologyas a Pre- and Post-Radiofrequency Microneedling Regimen.

Postoperative recovery is an important consideration for patients planning dermal rejuvenation procedures. A topical procedure enhancement system (PES) containing a tripeptide and hexapeptide (TriHex Technology; Alastin Skincare, Carlsbad, CA) hastens recovery from facial rejuvenation procedures, such as laser resurfacing. We assessed the efficacy and tolerability of the PES compared to a standard-of-care antioxidant regimen for improving recovery following three monthly facial radiofrequency (RF) microneedling treatments. Assessments included grading pre- and posttreatment digital images by two blinded physicians and a subject satisfaction questionnaire. Digital images revealed significantly less post-RF erythema following the introduction of the PES in a crossover study. Similarly, the side treated with the PES in a split-face study demonstrated significantly less post-RF erythema than the antioxidant regimen. Participants expressed preference for the PES. Expected adverse effects included immediate, posttreatment erythema, edema, and burning/stinging. Other adverse effects included acneiform eruptions in patients treated with the antioxidant regimen ( = 2) and the PES regimen ( = 1) and mild dermatitis in another PES-treated patient. A topical PES containing a tripeptide and hexapeptide appears to be a safer and effective regimen for reducing posttreatment erythema and accelerates recovery following RF microneedling.
