Selection and preference for botulinum toxins in the management of photoaging and facial lines: patient and physician considerations

Abstract

Various noninvasive to minimally invasive techniques can be used for the improvement of cutaneous changes seen with photoaging. These include dermabrasion, chemical peels, ablative and nonablative lasers, and filler agents such as hyaluronic acid. However, the most common nonsurgical cosmetic procedure performed in the treatment of rhytides is injection with botulinum toxin. Its extensive safety history and relative ease of use by the practitioner has led to high satisfaction in millions of patients. Nonetheless, proper training of the fundamentals in injection technique, the choice of the appropriate candidate, and knowledge of potential adverse events are imperative to ensure a satisfactory and safe outcome.
