Nobody wants wrinkles. With all of the options available today, there is no need to wait until your 30's. If you can see lines running across your forehead at rest (meaning you are not raising your eyebrows and still see lines), then you will benefit from Botox no matter what your age. I see plenty of women under 30 who are regularly receiving Botox injections in my office. Starting Botox injections this early will prevent deep wrinkles from forming, which if not treated until later, will take several injections spaced months apart to correct. You really want to prevent deep wrinkles from forming before it becomes etched in the skin memory.
