Beauty standards are in a constant state of flux, often pushing fashionistas towards almost fantastical transformations. One day, thick, bold brows are in, and the next, thin, meticulously plucked arches make a comeback. Yet, some features are harder to alter. Some of them already know the answer, as they saw those very lips staring back at them in the mirror before seeking out the help of plastic surgeons.

Angelina Jolie, the gold standard of sensuous lips, stands out even more because all that beauty is completely natural.

Scarlett Johansson, another embodiment of perfect lips, is also blessed with hers naturally.

Kylie Jenner, on the other hand, has been open about her lip enhancements. As a teenager, she was self-conscious about her thin lips, and as soon as she had the chance, she “fixed” what she considered a flaw.

And this is how Kim Kardashian might look:

Model Kendall Jenner denies getting lip fillers, though fans remain convinced that cosmetic enhancements were involved, eagerly comparing her “before and after” photos.

Adriana Lima, one of Victoria’s Secret Angels, boasts an angelic face, with lips that are enchantingly full.

Christina Aguilera, even with thin lips, remains striking, but she, too, joined the ranks of stars chasing that fuller look.

Emily Ratajkowski waves off speculation about lip augmentation, insisting that her plump lips are completely natural.
