I am 19 year old male , can i get plastic cosmetic surgery without knowing perents at the age of 21 ?

Ask your doc!: You've listed both india & blitzen, flanders as your place of residence. I am not familiar with legal statutes as far as treating "minors" in those or any other countries aside from the states, where you're an adult as of 18yo but can't drink until 21yo. You'll need to ask your surgeon.

Plastic surgery: I'm not exactly sure what you are asking but i think you want to know if you can have cosmetic surgery without knowing anything about your biological parents. If that is the question, the answer is yes.

Consent age - choice: To be considered a candidate for any cosmetic surgery, psychosocial stability and the ability to give informed consent are considered baseline requirements. If you are of legal age then not wanting your parents to be part of the decision making for surgery is your choice.

Plastic surgery: At 18 you may have surgery and no one needs to know! this is the legal age of consent. Good luck!

Yes: You are over the age of 18. You may sign for yourself. It is usually best to have support when going through surgery. Each case is different. See a board certified plastic surgeon.

Yes;4 right reasons: Yes, at 19, you are able to give consent without your parents. Make sure you are having surgery for the right reasons.
