Kirsten was introduced to the world of Medical Aesthetics in 2019, following a car accident. She experienced debilitating chronic migraine headaches daily. After countless failed medication and other treatment attempts, her Neurologist recommended Botox. Within two weeks, her migraine headaches began to disappear. Receiving Botox injections every three months has completely changed and improved her life. She experienced pain relief and the bonus of smooth and younger looking skin. Kirsten is a true believer in both the therapeutic and cosmetic benefits of Botox.
