Throwback Pics Show Christina Aguilera's Lips Before She Pumped Them With Filler

Musician Christina Aguilera rose to fame in the late '90s, and ever since, she has been one of the most well-known pop stars on the globe. The "Genie In a Bottle" singer's impact on the evolution of Y2K beauty and fashion trends is undeniable, and over the years, the star managed to remain relevant, thanks to her social media presence as well as projects like "The Voice."

Nevertheless, the complete transformation of pop singer Christina Aguilera showcases that the star wasn't immune to beauty trends. In fact, before and after pics of Christina Aguilera's face won't quiet those Ozempic rumors, but there's more. Photos of the musician from the late '90s and 2000s reveal just how much her lips have plumped up over the years. Speaking to Allure in 2023, Aguilera admitted that she was no stranger to injectables. "I think we all can rely on a little help. Why not?" she said, adding, "I think it's great to share and to be honest and open about what you're doing — in your comfort zone, of course. I've always been a pretty open book about embracing my body, my looks, and things like that." However, Aguilera has yet to address using lip fillers directly, but throwback pics of the star clearly show how much thinner her lips used to be, and no amount of overlining could make them as plump as they are today.

When Christina Aguilera had her breakthrough in the late 1990s thanks to hits like "Genie In a Bottle" and "What a Girl Wants," it was instantly clear that a long career awaited her. At the time, Aguilera's makeup was all about frosty and colorful late '90s and early aughts trends, and for her lips, that meant rocking a metallic lip gloss. Apart from her natural lips, pics from 1999 also showcase Aguilera's natural teeth, prior to her reportedly opting for veneers.

While Christina Aguilera has opened up about the use of injectables like Xeomin — a neurotoxin similar to Botox — she never revealed whether she used it to treat her very subtle gummy smile. Those familiar with neurotoxin know that it is often injected around one's upper lip to prevent it from wrinkling inward when smiling. In fact, this has resulted in quite a few celebrity smile transformations that were hard to miss, and Aguilera can easily be added to that list.

Throughout early 2001, Christina Aguilera's sound and style became more experimental, as the singer was transitioning away from her pop princess image into a musician whose confidence was unrelenting. Beauty-wise, she was experimenting a lot with her makeup, but mostly focusing on her eyes. Her lips still looked natural, even though Aguilera was subtly outlining them and always going for a glossy finish. And yes, this was the era of cultural appropriation by celebrities, and Aguilera's braided hairstyle certainly wouldn't go by unnoticed today.

During her "Dirrty" era, Christina Aguilera's lips were mostly covered in nude lipstick. At the time, the pop star was all about dramatic eye makeup, and she rarely combined both. Looking back at photos of the star in the early 2000s, it's clear that Aguilera never really had thin lips; instead, they were proportionate to the rest of her features. At the time, the "Beautiful" singer also rocked a chin labret piercing, drawing attention to her lips even more.

As the mid-2000s approached, Christina Aguilera began wearing red lipstick more frequently, often pairing it with a shiny gloss. With still no filler or neurotoxin in sight, the singer's pout had plenty of natural movement, and photos from 2003 showcase a subtle asymmetry in her lips while talking, a common occurrence, as most people's faces are rarely perfectly symmetrical. Nowadays, the singer's facial features — lips included — seem a lot more even, which is another telltale sign that she has used injectables.

It's no secret that lighter lipstick shades tend to make one's lips appear bigger, while darker and bolder colors often make them look thinner. Knowing this, Aguilera always paired her "Back to Basics" era bold red lips with a gloss on top. That way, some of the light would reflect, making her lips appear juicier and plumper. It is unclear when exactly the star's face began changing, but in the mid-2000s, her features still seemed very natural.

Two decades ago, Christina Aguilera 's makeup game was the epitome of 2000s trends. The star was frequently rocking blue-gray eyeshadow, which perfectly enhanced her blue eyes. Aguilera would pair the bold eye makeup with baby pink lips, a trend that was incredibly popular in the second half of the 2000s, thanks to stars like Nicki Minaj. In hindsight, the lip color was perhaps a tad too cool for her features, but it undeniably drew attention to her still natural-looking lips.

In 2006, Christina Aguilera's makeup became even more stunning, with the star's base being flawless and perfectly contoured. The singer's eyes were rarely seen without false lashes, and her lips were often painted in darker shades of red. The use of concealer to outline her lips was noticeable, always creating a sharp contrast. Nevertheless, her lips still looked the same, indicating that the star hadn't changed them yet.

Regardless of whether the singer injected fillers or did a lip flip, in 2007, Christina Aguilera's smile was noticeably different from what it looks like in the 2020s. And while there was still a subtle asymmetry in the volume of her upper lip, by 2007, the musician's makeup artists ensured to create a more balanced cupid's bow with makeup. The fact that Aguilera was still in her red lips phase certainly helped.

In the late 2000s, Christina Aguilera continued experimenting with her look, and for her makeup, that usually meant trying out new styles. Slowly, her days of the classic red lip were coming to an end, as the star was now gravitating towards graphic eye makeup. For her lips, Aguilera stuck to nude shades with a glossy finish, creating a soft look. In the mid-2020s, the star's lips look drastically different.
