Yes
Why not? It’s like giving braces or earrings—a reward for being good or doing well in their studies, so why stop at just braces and earrings? Minimally invasive aesthetic procedures such as contouring using botulinum toxin injections can help to reduce square jaws, while fillers can help with nose or chin augmentation. If such procedures can boost a teenager’s self-confidence and self-esteem, I say go for it.
For more invasive procedures, I am open to nose jobs to correct crooked or hooked noses, which can potentially cause insecurities among teenagers. However, I will draw the line at boob jobs as they are purely for beautification purposes. Liposuction to fight obesity? I think that would be excessive, and would prefer these young people to address such concerns with exercise and a good diet.
My advice to parents of children undergoing aesthetic fixes is help them find a reliable practitioner, be there to support them and prevent them from going overboard.
