Kendall & Kylie Jenner’s Beauty Evolution, From Tweens To Cultural Phenomenons

At the beginning of it all, Kendall and Kylie were mere tweens — and glammed up accordingly.

While Kendall kept her middle part going, Kylie experimented with some full bangs and (heavy!) black eyeliner.

Kylie softens her look with a very 2010 side bang, while Kendall keeps things consistent with minimal makeup.

By 2012, the ladies are leaning more into glam, with Kendall wearing her now-signature sleek low bun and Kylie with some extensions.

Bronzed up, both of the Jenner girls try out some honey highlights and bouncy waves.

Kendall goes back to her dark, solid-colored hair, while Kylie enters her short, dyed ends phase, starting with some honey blonde.

The girls lean into their personal styles, with Kendall retreating back to her sleek middle part, and Kylie introducing her vibrant green-blue look.

Kendall continues with clean and simple, and Kylie's "over-drawn" lips onset a long-lasting pop culture conversation.

Only a couple years into her high-fashion career, Kendall is taking the job seriously with mature glam and a wispy bun. Kylie has discovered wigs — and officially capitalized on her lips, launching the Kylie Cosmetics Lip Kits in 2015.

For this appearance, both Jenners interpret sleek, black hairstyles in their own way.

In her peak Snapchat days, Kylie wore a long, honey blonde wig and mauve lipstick, while Kendall kept it natural with her hair pulled back.

Both with top buns, Kendall and Kylie kept their skin glowy and the focus on their brows.

Kendall played up her signature red lip and up-do, while Kylie wore a high ponytail and bold contour. This year on an episode of "KUWTK," she finally opened up about her much-discussed lip fillers.

Some of the most memorable Met Gala looks of 2019, the sisters went full, glowy glam — Kylie with a long lavender wig, and Kendall with her signature bun played up with some artful baby hairs.

13 years later, Kendall has kept consistent with her sleek middle part bun, glossy lips, and glowing skin. Today, though, she keeps her brows thick and fluffy, brushed up for a natural look.

With a successful beauty empire under her belt, Kylie is constantly experimenting with different wig colors and lengths — though she wears her natural hair out for sharp up-dos like this from time to time.
