Effectiveness of a nutraceutical during non-ablative 1927 nm fractional laser on patients with facial hyperpigmentation and photoaging

: Background: Fractional lasers have been proven to treat hyperpigmentation and photoaging. Little research has been done on the effects of supplements on healing post-laser resurfacing. A nutraceutical could offer the benefit of faster healing of the skin and fewer side effects. Objective: Evaluate the effectiveness of a nutraceutical associated with fractional 1927 nm laser in healing time and effectiveness on hyperpigmentation and photoaging. Methods & Materials: A prospective, randomized, evaluator-blinded, pilot study included Fitzpatrick skin types I-III patients with hyperpigmentation and photoaging randomly assigned to two groups. Group 1 was laser treatment and Group 2 was laser treatment and nutraceutical. Results were compared with objective biometric TEWL (transepidermal water loss), mexameter, corneometer, and cutometer parameters. A blinded physician-evaluator and the subjects completed questionnaires to evaluate skin improvements. Results: Twenty women were included. Eight in Group 1 and 10 in Group 2 completed the study. Group 2 presented a faster recovery of the skin barrier function post procedure. Three months after the procedure, Group 2 presented with significantly improved skin glossiness, hydration, and melanin rebound levels. Group 2 presented more overall aesthetic improvement determined by the patient and the blinded physician-evaluator. Conclusion: The nutraceutical improved the results of the laser treatment.
