It’s been more than two decades since Christina Aguilera shot to fame as a midriff-baring ’90s pop star, but she’s barely changed over the last 25 years.

Since kicked off her career with debut single Genie In A Bottle in 1993, she’s gone on to release eight albums, tour the world and become mum to two kids.

Despite such a long career in the public eye, Chrissy, 38, still looks incredible – now a top surgeon has revealed how the singer has maintained her ageless beauty.

A top surgeon for MYA Cosmetic Surgery told us Christina is likely to have undergone a variety of procedures to battle those dreaded wrinkles.

Botox

“I would suggest Christina has had anti-wrinkle injections, often referred to as Botox, to her forehead and around her eyes (crow’s feet).

“This non-surgical treatment will create a smooth forehead and limit any frown/expression lines.

“The treatment will normally last 3-6 months – as muscle action gradually returns, the lines and wrinkles begin to reappear and need to be treated again.

“This procedure can give the appearance of smoother skin if you are after a youthful appearance or it can be used as a preventative measure to slow the process of getting fine lines or wrinkles.”

“It is possible Christina has had jawline and chin contouring with non-surgical dermal fillers.

“This treatment creates a more defined and slimming look to the chin and jawline and can cost around £150 to £300 per session, depending on the amount of product used.

“Weight loss can also affect a similar change of the face shape, but fillers will help create specific definition in this area.”

Cheek fillers

“I would also suggest she has had the non-surgical treatment of dermal fillers to her cheeks.

“Fillers give volume to the cheek area and this is achieved by injecting dermal fillers along the contour of the cheekbone to create more definition.

“This treatment can typically cost in the region of £200-£500 per session depending on the amount of product used.”

“I believe that Christina has also undergone the non-surgical treatment of fillers to her lips as she appears to have slightly fuller lips compared to previous images.

“The average cost of lip fillers in the UK can range depending on the provider and the amount of filler used, however, you can expect to pay anything from £200 – £1000 per treatment.

“We believe Christina looks amazing so clearly whatever she’s doing is working. It’s important to keep the balance of non-surgical treatments though – you can retain your youth but not overfill with products.”
