The reality star recently revealed that she underwent ten procedures in one day, admitting that she is "obsessed" with plastic surgery.
Speaking to People, Bosworth said: "I hope that girls don't read the article, look at the decisions that Heidi made, and think that's normal.
"She was quoted as saying that [practically] every celebrity in Hollywood has these procedures done, every day... and that's just not true. I would never want young girls to read that and think it's the standard that they need to be measured by."
However, the 23-year-old added that she "is not against" cosmetic surgery, saying: "If some wrinkles come across my face, sure, I'll get a little Botox, it's not a big deal.
"I think you should do what you want to do to take care of yourself. I just hope that the girls who look up to us and watch us don't look at what Heidi did as the only way to be successful and beautiful."
Co-stars Jayde Nicole and Audrina Patridge have also spoken out about Montag's surgery, while Emmy Rossum reportedly claimed that it was "upsetting" to see stars "advocating plastic surgery".
