Did They or Didn’t They? 30 Celebrity Botox Transformations

"I don't like Botox," Paltrow told Cosmopolitan UK. "I think on some faces it works, but it's when you can really see it that it starts to look fake. I think people look at tiny patches of their face and try to fix everything — they've lost the plot!" Now steaming her vagina? That's a different story.

"I don't believe in Botox, especially when [people] do it so young," Hayek tells People. "They destroy themselves. They keep telling young girls, 'Do it young, so you never get wrinkles.' No, your face is going to fall. You'll have to keep getting more and more and more each time. So if you're going to do it, I recommend doing it as late as you can." No word on whether or not she's dabbled yet.

Diaz tried Botox but didn't like it. She says of botox, it "changed my face in such a weird way that I was like, 'No, I don't want to be like that.' I'd rather see my face aging than a face that doesn't belong to me at all."

Cam has "no judgment on how people feel good" and totally gets why people undergo procedures. "They're to help people feel a little bit better about themselves," Diaz wrote in The Longevity Book. "If they do feel better about themselves, then those procedures have worked. I have no problem with that. And [in] a lot of instances, it does make you look like you've taken a nap ... or that you might be a little younger than you looked maybe the day before."

Similar to Diaz, for Vergara it's whatever floats your boat. "If it makes you happier and more confident, then why not? But I also think you have to do your research, so you know what to expect — that you'll look fresher but not necessarily younger. I don't want to age, but hey, what can you do? It's a natural process. I'm trying to do it gracefully."

Julia, on the other hand, is a little judgier. "I want my kids to know when I'm pissed, when I'm happy and when I'm confounded," she told Elle. "Your face tells a story and it shouldn't be a story about your drive to the doctor's office."

Real Housewives of Beverly Hills star Lisa Vanderpump has admitted she occasionally gets injectables such as Botox and fillers and is happy to give credit where credit is due.

"Everybody f*cking does it," Wright tells the Telegraph. "I suppose I can't say 'everybody' because I don't know for sure, but come on. It's just the tiniest sprinkle of Botox twice a year. I think most women do 10 units, but that freezes the face and you can't move it. This is just one unit, and it's just sprinkled here and there to take the edge off ... Perhaps it's not wise to put that in a magazine? But I ain't hiding anything."

For Cox, it was a snowball effect. "I was trying so hard to keep up, and I actually made things worse," Cox confessed to NewBeauty. "What would end up happening is that you go to a doctor who would say, 'You look great, but what would help is a little injection here or filler there.' So you walk out and you don't look so bad and you think, no one noticed — it's good. Then somebody tells you about another doctor: 'This person's amazing. They do this person who looks so natural.' You meet them and they say, 'You should just do this.'"

"The next thing you know, you're layered and layered and layered. You have no idea because it's gradual until you go, 'Oh sh*t, this doesn't look right.' And it's worse in pictures than in real life.'"

It's been a long road and a learning curve but the actress has had all her fillers dissolved and is now "as natural as I can be."

"I think what I have been witness to, is seeing women trying to stay ageless with what they are doing to themselves," Aniston told Yahoo! Beauty. "I am grateful to learn from their mistakes, because I am not injecting s**t into my face." She's talking about bestie Courteney, right? Don't pretend we're not all thinking it.

"I don't believe it makes people look better," Moore said to Allure when asked about cosmetic procedures, like Botox. "I think it just makes them look like they had something done to their face, and I don't think we find that instinctually appealing."

Winslet has always denied the Botox rumours, no matter how rampant they got. "Just a couple of hours ago, my publicist sent an email saying that some journalist from the Daily Mail has a picture of me from an event last night and is saying that I appear to have lost all the baby weight and how did I do that? And do I want to comment on the fact that experts are saying that I've had Botox?," Kate recounts to WSJ. magazine. "I just get irritated by that sh*t. First of all, the latter is 100 percent not true, and secondly, it's f*cking 18 months later. Of course I'm going to get back at some point." You tell 'em, Kate.

"I'm one of those people who thinks less is better," the Real Housewives of Beverly Hills star told People. "There are so many people who have so much done to their face. They never look better! I'm not one of those women who is like, 'Every wrinkle has made me who I am,' but I'm also not the person who doesn't want to age. My mom died young, so for me, every birthday is a reason to celebrate."

"Facelifts and Botox are very different. One is more extreme," she tells New York Mag's The Cut. "I don't want to knock that stuff — to each their own. But I also feel like there's a look. When you start doing that, you start looking the same as everyone else. Because unfortunately, you're conforming to something and your face doesn't move. Everybody's faces blend into each other and the more surgery you do — with the big lips, skinny nose and tight brow — why would you want to look like everybody else [in Hollywood]?" But it seems like she's kinda knocking it, right?

If, like Amanda, you don't want to go so extreme to stay youthful, here are 10 skincare mistakes that are aging you that you need to avoid.

"We've been so conditioned now to never see a real human face, one that moves, with its original teeth," Fey told Town & Country. "Sometimes we forget that there is a choice. I choose not to do this. It's like wearing multiple pairs of Spanx: Good for you, not for me. Not mandatory."

The reality star has admitted she's "made some mistakes" as far as fillers and Botox goes, but she owns it, saying, "There's no shame in my game." Keeping it real, as usual.

Kim K. admitted in a 2010 episode of Keeping Up With the Kardashians that she had tried Botox. "I had some bruising around my eyes after the procedure, which is totally natural, but because I hadn’t looked into the side effects, I freaked out. Botox just wasn’t necessary for me at [that] age." That was then; now, on the other hand?

"I've tried a lot of things, but aside from sports and good nutrition, most things don't make a difference," Kidman says. "I have also tried Botox. I didn't like how my face looked afterwards. Now I don't use it anymore — I can move my forehead again!"

Real Housewives of New York star Bethenny Frankel admitted she's had Botox — but not for the reasons you might think. "I had my jaw injected with Botox because I have TMJ, and if you look at pictures of me from probably like seven years ago, it's gradually gotten smaller to the point that I had to stop, and now it actually hurts again," she said on Watch What Happens Live.

This reality star is keeping it real. "My goal is to never get Botox or any other filler or injectable, for that matter," she writes in her book Balancing in Heels: My Journey to Health, Happiness, and Making It All Work. "I don't hate on people who get Botox; I would just prefer to do everything a more natural way. We don't know the long-term effects of that stuff, and it doesn't seem right to me. We are supposed to age — that's part of life!"

While it's her lips that get most of the attention, Real Housewives of Beverly Hills star Lisa Rinna has admitted to also getting Botox injections. It's all about balance.

The morning show host let other's opinion dictate her decision to try Botox. Big mistake.

"I'm going to tell you a story I've never told anyone," Ripa told guest co-host Megyn Kelly during a taping of Live!. "I got bad Botox about ... what was it, a year ago? And it was bad. It did something to my good side, so then I had two bad sides. I'm not kidding!"

She continued: "I'm starting to look myself again, but there was about a six-month period where people were like: 'What's wrong with Kelly? She doesn't smile anymore.' And I was like: 'I am smiling!'" Funny now, not so much then.

"I was the first person to ever admit that I did Botox, and my mom was upset," Evangelista told Harper's Bazaar. "I said, 'Mom, everybody does it,' and she was like, 'Yeah, but they don't say it.' So if I was the first one to tell the truth about using it then, why would I lie about it now?"

That was then, but check out the plastic surgery trends that are all the rage today.

Shields has tried it, didn't love it, but admitted another procedure intrigued her. "I want laser treatment because I'm not a fan of my wrinkles," she revealed in Ladies' Home Journal. "But I have to find someone with a light touch. I'm scared I'll end up looking like the Joker."

The "plastic lover" (her words, not ours) admitted to People that she needs to lay off of some procedures. "I feel there have been times where I completely over-do it,” she told the mag. "I've had every part of my face injected. The things I've decided to stop doing is the filler in the cheekbones, the Botox above the eyebrow and the lips because I just feel like I'm a walking cat-duck. It looks like a cat and a duck had a baby and that's me." Now the Vanderpump Rules star only get injected at her jawline, chin and forehead.

As far as the rest of the world goes, have at it. "If you like injections and you like plastic surgery I feel like, if you feel comfortable and you feel beautiful, than do you, boo."

Khloe doesn't even know what particular procedure messed with her face but she didn't like it.

"I don't know if it's Botox or filler, [but] I did one of them and my whole face went numb and I could not make [an expression]," Kardashian said during an episode of Kocktails With Khloe. " I had to dissolve everything ... I looked crazy and I still think the effects are like, in there."

She added: "And my face was so f*cked, I had to go and get this whole thing, like, dissolved. It was a bummer because now I'm afraid to do it again."

Dewan constantly sparks Botox and plastic surgery rumours but she revealed that while she hasn't had any fillers, she does get a bit of work done for her melasma — a skin problem that causes brown patches — from the same dude Lisa Vanderpump goes to.

The actress has "done it all," telling the Mirror she's had plastic surgery, liposuction and Botox but confessed that "none of it works."

"I've bleached my teeth, dyed my hair, peeled and lasered my face, and tried a slew of age-defying creams," the actress wrote on Lenny. "More than once, I've asked the director of photography on a show to soften my laugh lines. Nothing about this suggests I'm aging gracefully. Yet for me, it would be crossing the Rubicon to add Botox and fillers into the mix."

The former Real Housewives of Beverly Hills star revealed that while she has her original nose and cheekbones, she has had fillers and gets Botox. "But it's definitely not surgery."

"L.A. scares the crap out of me," Watson told Harper's Bazaar U.K. "I feel if I have to work out four hours a day, and count the calories of everything I put in my mouth, and have Botox at 22, and obsess about how I look the whole time, I will go mad, I will absolutely lose it."
