I heard that Ock Joo-hyun gets Botox regularly...

However, among the common side effects of Botox... 1. Once you get Botox, you have to keep getting it, and 2. Because the ingredients are toxic, you don't know how it could turn into a threat to the human body in the future... (It can only be said to be safe after 30 years since plastic surgery was introduced, but Botox has been around for about 15 years. I heard) 3. It is said that when the Botox ingredient runs out, the skin becomes saggy. If it is 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...;; I want to get rid of the wrinkles around my eyes..ㅜㅜ
