Yes. I've had Botox. I should say I have Botox 'cause I just got it a month ago (for the 2nd time). I love it. I work for a cosmetic dermatologist, so Botox, Restylane, and all those things are what I talk about and assist with every day. We see a few men for Botox, and it's a great option. Men just have a harder time "admitting" that they want Botox, because cosmetic treatments are largely marketed towards women.
But Botox, Restylane, and such are not just for women! I'd say go for it. But find an experienced dermatologist to do it, so you get the right results you're after with minimal to no side effects. You can go to the Botox Cosmetic website and search for a doctor in your area who is a member of the Botox network.
