A topical regimen improves skin healing and aesthetic outcomes when combined with a radiofrequency microneedling procedure.

INTRODUCTION

Novel topical products formulated using tri- and hexapeptide technology (TriHex Technology ; Alastin Skincare , Inc) are used to clear the extracellular matrix, stimulate neocollagenesis and elastogenesis, decrease inflammation, and accelerate the epidermal healing process.

AIMS

This study assessed the efficacy of two topical tri- and hexapeptide-containing products pre- and post-treatment with radiofrequency (RF) microneedling of the photoaged neck with respect to healing and aesthetic outcomes.

SUBJECTS/METHODS: In this open-label, nonrandomized study, eligible subjects underwent one screening visit, one RF microneedling procedure and follow-up visits on post-treatment Days 3, 7, 30, and 90. Subjects were instructed to apply one product to the neck for 2 weeks prior to treatment and 7 days post-treatment. On post-treatment Day 7, subjects switched to the other product until the end of the study. At each visit, subject and investigator questionnaires were completed and standardized digital images were obtained.

RESULTS

Female subjects (N = 10) with a mean age of 51.3 years (range, 44-59 years) completed the study. All subjects achieved statistically significant improvements in Investigator Global Assessment scales at post-treatment Day 90 and reported improvement in all Skin Quality Assessments. Among Subjective Tolerability Assessments, all post-treatment reports of tingling and burning resolved by Day 3. 90% of stinging resolved by Day 3 with 100% resolving by Day 7. 40% of subjects had minimal itching on Day 3 which resolved by Day 7. Among the Investigator Post-treatment Tolerability Assessments, edema resolved in all subjects by Day 3 and erythema settled between Day 3 and Day 7.

CONCLUSION

Pre- and post-treatment use of topical products formulated with tri- and hexapeptide technology appears to hasten healing and complement aesthetic outcomes associated with RF microneedling of the neck.
