Totaling a whopping $1,244, her daily skincare regiment is full of pricey creams and oils that hold the secret to the 29-year-old's still Disney-like glow.

Among her list of must-haves, Hilary credits brands like La Mer and Laura Mercier, as well as her dermatologist Dr. Lancer, who also works with A-list beauties such as Kim Kardashian.

However, the "So Yesterday" singer has stayed pretty quiet when it comes to plastic surgery rumors. While it is pretty well known she got veneers after chipping her tooth while performing, critics believe she has gone under the knife for more subtle changes.

Hilary has been accused of undergoing a rhinoplasty, lip injections, and even breast implants. She did speak out when she was accused of getting lip injections in 2014, tweeting, "Same lips I've always had, know u need stories, in this case, it's just red lipstick and a fancy angle."

Instead, Hilary credits her glow to being young at heart.

"I’ve had to be mature my whole life since I’ve had a career since I was… what, 10 or 11? But my personality is very young and I have a lot of energy," she told Paste. "I think that sometimes I feel like the baby, and then other times, I’m like 'Whoa, I’m too old to be here,' or too old to be doing this."
