The countdown to the holidays is officially on!
While many people think of tricks they can do at the last minute, there are actually some key steps you should start ahead of time.
Inside Edition teamed up with No7 and its beauty expert, Gretta Monahan, for the ultimate holiday beauty checklist.
"A great way to brighten up your look is with teeth whitening strips," Monahan said. "Use those once a day, three to five days before your event, and you will sparkle."
And don't make the mistake of waiting until the day before to get a haircut, she said.
"Give yourself a week out and that way you can get used to the new length," she said.
Finally, she recommends adding a serum to your routine a month in advance.
"I love No7's Protect & Perfect Intense Advanced Serum because it's clinically proven," she said. "In fact, 96 percent showed a reduction in wrinkles."
The serum has earned the rigorously tested Good Housekeeping Seal, "so you know you can trust it!" she added.
You can get the serum at Target for less than $30.
