Lauren Conrad suggests using shimmery lipgloss to make lips look fuller.
The former reality TV star has released a beauty book in which she reveals the secrets to her flawless appearance.
Among those are how to make thin lips look as plush as possible.
"If you want to make lips look fuller, avoid dark colours and use shimmery lipgloss on the middle of your lips," Conrad told Look magazine.
She also spoke about how to keep hair looking its best.
The star is known for her blonde locks, which she has jazzed up with pink streaks in the past, and always makes sure she has the right equipment to care for it.
"Don't tie your hair in too-tight ponytails as this can make it break. Use gentle elastics with no metal fastening," she said.
The 26-year-old's best advice is to think about what you eat if you want your skin and hair to look healthy.
"Looking good starts with eating right," she said."Include proteins and vitamins in your diet for healthy skin and hair growth. And lentils and lean steak will keep your iron levels up."
