Nicola Peltz's appearance has evolved subtly over the years, prompting discussion among cosmetic experts who have analyzed her changing features. These observations follow the actress's recent appearance in a daring nude photograph and her role in the upcoming film "Prima," which required rigorous ballet training.

While Peltz, 31, has not publicly confirmed undergoing cosmetic procedures, experts have offered insights based on photographic evidence. Dr. Hassan Galadari, an aesthetic doctor and dermatologist, suggested that subtle changes might be attributable to treatments such as anti-wrinkle injections like Botox to maintain a smooth forehead and soften expression lines. He also noted that her brows appear slightly higher, a possible result of a brow lift, which can be achieved surgically or non-surgically.

Galadari further commented on Peltz's nose, suggesting it appears more refined, which could indicate a surgical or non-surgical rhinoplasty. He also highlighted the quality of her skin, describing it as consistently smooth, bright, and even-toned, potentially achieved through skin rejuvenation treatments like IPL, including Lumecca Peak, to address pigmentation, redness, and sun damage.

Plastic surgeon Dr. Paul Banwell added that changes in facial contour and skin quality can reflect a combination of factors, including natural aging, weight fluctuations, skincare, makeup, lighting, and potentially cosmetic treatments.

Earlier this year, Peltz's appearance on New Year's Eve sparked speculation regarding her teeth and lips. Dr. Mervyn Druian, of The London Centre for Cosmetic Dentistry, suggested that Peltz may have veneers, noting that they appeared whiter, larger, and more pronounced in recent photographs compared to earlier ones.

Dr. Rosh, an aesthetics doctor, speculated that Peltz's fuller-looking lips could be the result of a "lip flip" procedure or regular filler. He explained that the effect of lips remaining softly full even when smiling, without thinning or rolling inward, can be achieved through a combination of subtle lip filler for shape and hydration, and a small dose of botulinum toxin to relax muscles that cause the lip to fold under during expression. Dr. Rosh emphasized that this is an educational observation and not a claim about any individual's treatment.

The "lip flip" procedure is described as a minimally invasive technique to enhance lip contour and fullness without adding significant volume, offering a subtle enhancement.

During her training for "Prima," Peltz reportedly dropped to under 100 pounds after four months of intensive ballet work. The actress is the daughter of billionaire Nelson Peltz and first gained recognition for her role in "Bates Motel." Her public appearances date back to her teenage years, showing a notable evolution in her look since her early red carpet events. The Daily Mail has contacted Peltz's representatives for comment.
