However, among the common side effects of Botox... 1. Once you get Botox once, you have to keep getting it, and 2. Because the ingredients are toxic, you don't know how it might turn into a threat to the human body in the future... (It has to be 30 years since plastic surgery was introduced before it can be said to be safe, but Botox has been around for about 15 years. I heard) 3. They say that when the Botox ingredient runs out, the skin becomes saggy... If it's that bad, would Ock Joo-hyun get it regularly?? Ock Joo-hyun must have made a lot of money.. Plastic surgeons also say that it is safe with no side effects at all.. I wonder which statement is correct...;;
