In a past interview with Women’s Health, Underwood opened up about her dental journey. She explained that she had braces as a teenager, but like many people, she stopped wearing her retainer, which led to her teeth shifting over time.

Later in life, she decided to correct the issue, telling the magazine, “I eventually went to an orthodontist because I had one tooth that was driving me crazy… It’s such a little thing, but it’s only gonna get worse, so let’s fix it now.”

She mentioned that the issue was resolved in three months, during which she continued making public appearances, including walking red carpets, without anyone knowing she was wearing braces.

Underwood’s latest Instagram post may have sparked a debate about her appearance, but it’s a reminder of the intense scrutiny that celebrities often face. It’s not the first time this year that internet users noticed a transformation in her appearance.

Underwood’s collage photo back in June stirred the online community as they showed her transformation. The picture showcased a striking difference in her appearance with and without makeup.

The collage comparison left fans in awe and sparked a lively debate about her natural beauty versus her glamorous, made-up look. In the photos, where Underwood was fully made up, her transformation was nothing short of breathtaking.

With expertly applied makeup, her cheekbones appeared beautifully contoured, giving her face a sculpted look. Her nose seemed slimmer, enhancing the overall symmetry of her features.

The makeup accentuated her lips, making them appear fuller and more luscious, while her cheeks were raised, adding to her youthful and vibrant appearance.

Carrie Underwood’s eyes stood out with an intriguing depth, framed by magnificent eyebrows that perfectly shaped her face. Her chin looked short and narrow, contributing to a delicate and refined look that dazzled her fans.

Without makeup, Underwood’s face revealed a softer, more natural side. Her skin exhibited a minimal natural glow and her cheeks appeared puffed, lacking the sharp contours seen with makeup.

Her lips looked thinner, and her chin appeared rounder and wider, contrasting with the narrow chin seen in her glamorous shots. Fine lines under her eyes added a touch of maturity, and her cheeks did not have the same lifted appearance.

The stark contrast between Underwood’s made-up and natural looks did not go unnoticed by her fans, who took to social media to express their thoughts. One user commented, “Not the same person,” reflecting the disbelief many felt.

Another added, “Not her totally different person,” emphasizing the transformation’s dramatic nature. Observing the differences in her facial features, a user noted, “Not same person facial features too different. Narrow vs wide chin. Easy to see.”

Some users focused on specific aspects, with one stating, “Nose is different.” One fan wrote, “Beautiful with or without it.” Another supportive fan added, “Still a pretty gal, clean face and all,” highlighting the enduring charm of her natural look.

Reflecting on her past, a user shared, “It’s definitely Carrie Underwood in both pictures. I remember her from American Idol when she was young, and that’s what she looks like,” providing a sense of continuity in her appearance over the years.

However, some fans speculated about potential cosmetic procedures, with one remarking, “She doesn’t look like herself. Musta had surgery.”

Underwood is aware that going makeup-free can be an occupational hazard for her. The country singer has also previously shared insights into her beauty routine and the role makeup plays in her life.

She revealed that she does her own hair and makeup while on tour, finding joy in getting glammed up even off the red carpet.

Having started wearing makeup at a young age, the “Cry Pretty” crooner felt that it gave her ample time to hone her skills. Still, she revealed that if she had a daughter, she would have encouraged her to wait a bit longer before diving into makeup.

But, for her, wearing makeup at a young age was a much-needed learning experience. Consequently, Underwood’s beauty routine during tours has become precious “me” time. It’s therapeutic for her to sit down with her makeup kit and do her makeup in silence amidst the busyness of tour life.

Even on days when she isn’t performing, the singer rarely goes without at least some mascara and blush. “I don’t think I ever have makeup-free days, to be honest. I wear makeup for me. I don’t want to walk by a mirror and feel like I haven’t given some sort of effort. I just feel better when I have a little on,” she confessed.

Furthermore, living in Nashville, Underwood faces the constant presence of photographers. Even quick trips to the grocery store can turn into impromptu photo sessions, making her prefer to wear some makeup as going makeup-free is not great for her professional reputation.

This approach Underwood takes helps her feel more prepared and confident, knowing that she can be photographed at any moment.
