Cosmetic surgery is a type of medical procedure that changes how a person looks. It usually involves changing or fixing parts of the body. For example, someone might choose to have surgery on their nose to make it thinner, or surgery on their eyes to make them bigger. Cosmetic surgery can also include things like Botox and laser treatments. It's important to remember that having cosmetic surgery isn't without risks and it's important to talk to your doctor before making a decision.
