Is 16 Too Young to Start Getting Botox?

If you are doing every thing else to maintain your apperance including avoidance of sun exposure ( no tanning beds, no tobacco use) good skin care, etc, I can't logically or ethically recommend this for a 16 year old and I can't imagine how your wrinkles could be that bad at your age.

I don't feel Botox is an appropriate treatment for your current concerns and age.  Personally, I worry about encouraging cosmetic procedures in people whose bodies are still growing and changing, and don't recommend, or perform, most such procedures in young adults.  I would be VERY wary of the motivations of a physician that would be willing to treat you.

You may develop many more lines in the future that are more noticable. Some (a minority) of patients not that after many years of treatment the Botox doesn't last as long. Don't start using your possible limited time of Botox effectiveness by starting so  young. Even if you find a doctor who would be willing to do it, I suggest you wait a decade or so. Use sunscreen every day, try to get a good night's sleep, exercise and eat a healthy diet. Use moisturizer for the facial lines and don't look too closely at your skin.
