Simon Cowell's appearance before and after surgery shows noticeable changes mainly due to non-surgical cosmetic procedures and lifestyle changes rather than extensive invasive surgery. Around 2018, he underwent a Silhouette Soft Lift, a non-surgical facelift using PLLA-based suture threads to tighten and smooth his skin. Prior to that, he had Botox injections and facial fillers, though he admitted to overusing Botox at one point and later had some fillers dissolved. His smoother, more youthful skin has also been attributed to laser therapy and skin care improvements. In addition to facial changes, Simon Cowell significantly transformed his smile through cosmetic dentistry. Between 2019 and 2020, he had extensive dental work with veneers that initially looked unnaturally white and uniform but were later adjusted to a more natural appearance after feedback. He also lost weight and changed his diet after a fall in 2017, which contributed to a slimmer, more toned look. Experts have noted possible minor procedures like a brow lift and blepharoplasty (eyelid surgery) to reduce hooding and open the eyes more. Overall, his transformation consists mostly of less invasive treatments combined with lifestyle and dental enhancements rather than major surgical interventions.
