Getting a regular manicure can be the most luxurious and relaxing experience. But whether due to the cost or a lack of time, heading to a nail salon for a regular nail appointment is not always in the cards.

For Sports Illustrated Swimsuit model Christen Harper, that is certainly the case. But, according to the 30-year-old, that shouldn’t stop you from regularly sporting a clean, finished nail look. Harper took to TikTok on Aug. 23 to share the secret behind her pristine natural nails, which she learned during her early days as a model.

For ease, the model usually has her nails painted with a simple clear sheen. But she doesn’t have naturally white tips, and so—to achieve a more natural French tip-inspired look—Harper uses a whitening pencil on the underside of her nails to enhance the brightness of her tips.

The simple Maitys Nail Whitening Pencil ($4.99) can be found on Amazon for your everyday at-home natural manicure needs. Simply apply the white tone to the underside of your nails—like Harper does—or to the tops for an even brighter look.
