INTRODUCTION: Carbon-assisted Q-switched Nd:Yag laser treatment consists in applying a topical carbon suspension all over the face followed by irradiation with a Q-switched 1064 Nd:YAG laser. The delivery of multiple microdroplets of dilute Onabotulinum Toxin-A into the dermis, has been investigated as a tool for facial rejuvenation. The aim of this study is to assess the effectiveness of the combined treatment with botulinum toxin and carbon peel laser (performed with a standardized technique) in patients with seborrhea, dilated pores and wrinkles, and to demonstrate its benefits in improving the overall skin aspect.

MATERIAL AND METHODS: Patients enrolled in this prospective pilot study were subjected to 3 sessions of the combined treatment carried out 3 months apart. To evaluate the improvement of skin texture, wrinkles, dilated pores and acne lesions, several scales have been used, namely Fitzpatrick Wrinkle Assessment Scale (FWAS), the Physician Global Aesthetic Improvement Scale (GAIS), a photographic scale for the pore assessment and the Investigator Global Assessment of Acne (IGA). Face Q was also administered to assess patients’ satisfaction. The scores obtained were compared using a paired T-test.

RESULTS: Twenty patients were recruited. Difference of pre and post-treatment scores of the FWAS, GAIS, IGA, Face Q and the photographic scale for the pore assessment were statistically significant (p < 0,05).

CONCLUSIONS: This combined protocol could be considered as an useful tool to treat skin flaws affecting texture, microroughness and seborrhea and to reduce enlarged pore size and its versatility allows customized treatment with minimum discomfort in patients.
