However, Hadid herself has denied any plastic surgery.
Speaking to InStyle in 2018, the model insisted, "People think I got all this surgery or did this or that. And you know what? We can do a scan of my face, darling. I’m scared of putting fillers into my lips. I wouldn’t want to mess up my face."
Hadid's claim that she has never gotten work done--not even fillers--definitely left some fans confused. Hence, people finding before and after photos to compare her strikingly different looks throughout the years.
What do the experts have to say?
Dr. Michael Keyes, the owner of the account @celebrityplastics and a plastic surgery fellow, told Vox that he suspected Bella had some degree of work done.
He explained, "A lot of the younger celebrities haven’t had too much work. It’s through non-invasive techniques, such as brow lifts with Botox and fillers." Still, that's not nothing like Bella claims.
With that in mind, it angered many fans that Bella would not be more forthright about the work she has done to achieve her model good looks.
Some fans even accuse her of perpetuating an unrealistic beauty standard. One Twitter user explained, "Bella Hadid denying she’s had work done is what’s wrong with society. Giving young girls unrealistic expectations to look up to, then pretending it’s all 'natural.' There’s nothing wrong with having work done, but own up to it."
