Considering people spend as many as 300 days a year squinting into the sun in Phoenix, Botox under eyes continues to be a popular treatment for crow’s-feet. Of course, there are many questions to consider. How long does Botox last? According to the team at Senza Pelo Med Spa, up to four months. And if you’re wondering about the side effects of Botox, know they can include anything from headaches to a rash to difficulty swallowing. Even if you’re not interested in reducing fine lines and wrinkles, remember that you can also get Botox for sweating. After all, the average temperature in Phoenix is 85 degrees. And if you decide Botox is not right for you, you may still consider longer-lasting cosmetic-surgery procedures or more temporary rejuvenating facials.
