Question:
Is a religious man allowed to get Botox injections and other cosmetic procedures?
Answer:
Botox prevents wrinkles and stops perspiration so might not be a problem. Other cosmetic procedures might be a problem, It depends if the procedure is done to remove an existing blemish or just purely to enhance looks.I suggeste you discuss the issue with a reliable Rabbinic Authority.
