Introduction: The skin is a marker of chronological age and appearance, being important for self-esteem and quality of life. Fractional ablative radiofrequency is one of the treatments aimed at delaying the effects of aging.
Objective: To describe the operating principles, methodology, and results of rejuvenation of the lower eyelids when treated with fractional ablative radiofrequency, and the resulting thermal damage observed on histology.
Methods: Twenty female patients with aging skin on the lower eyelids were selected for treatment with this method. In one of the patients, who concurrently underwent upper blepharoplasty, ablative fractional radiofrequency was carried out on the skin fragment to be removed from the upper eyelid for anatomical-pathological examination and measurement of thermal damage. The evaluation of clinical results was performed using photographic comparison and analysis of satisfaction questionnaires answered by patients.
Results: Photographic comparison showed significant skin retraction effects on the skin of the lower eyelids, while the analysis of questionnaires revealed a significant degree of patient satisfaction. Ten percent of patients experienced reversible local hyperpigmentation as a complication. Ablative and non-ablative damage was observed up to the superficial reticular dermis, with negligible thermal effects on the sides.
Conclusion: Fractional ablative radiofrequency was proven safe, effective, and cost-effective in skin rejuvenation, nevertheless further studies should be conducted with the aim of determining the optimal parameters, as well as the ideal number of sessions needed to achieve the best result with the lowest percentage of side effects.
