Dua Lipa's top skincare tips, from exfoliating with a toothbrush to microneedling

• Dua Lipa began using toothbrushes in her makeup routine in a pinch.
• She still uses the brushes to exfoliate her lips and keeps extras on hand.

Dua Lipa uses a toothbrush for more than just her pearly whites. Her dedication to dental hygiene paid off when she repurposed a spare brush in her beauty routine.

The pop star told Allure she regularly uses her toothbrush to exfoliate her lips, and she also keeps a couple extras on hand to double as eye makeup brushes.

"At home [in London], I discovered it after running out of makeup supplies and trying to make do with what I have. Now, I still use it," Lipa told Allure.

She clarified that she doesn't use the same toothbrush for all of her beauty needs, but she "occasionally" employs a separate one to fill in her signature thick brows with dark eyeshadow.

"And if I want a really thick, textured look with mascara, I put one on my lashes, as well," she added.

Here are the other skincare and beauty techniques Lipa relies on to keep her skin glowing.

She makes time for facial treatments, including microneedling

Lipa told Allure that when she's home In London, she likes to visit a facial spa called Pfeffer Sal every few months.

On a few occasions, Lipa has even tried microneedling, a skin treatment involving several tiny, sterilized needles that are meant to trigger collagen production. The treatment is supposed to heal dark spots and make the skin look younger, after some slightly painful side effects.

"My skin felt sunburnt for two days but, by the third, I had really good 'baby skin,'" the singer told Allure. "It lasted for a few days, but then went back to normal."

Lipa tries to go makeup-free when she's not on stage

The singer has a glam look when she's performing, but in her downtime, she likes to let her face breathe.

"I try not to not wear makeup as much as I can. I need to give my skin a break," she told Allure. "I guess it was always important for me to take my makeup off before bed, but now, it's like to a whole 'nother level."

When she opts to wear makeup in her personal life, Lipa keeps it basic. She told Elle UK her 15-minute routine consists of foundation or concealer, mascara, eyeshadow, and bronzer - "and then I'm out the door," she said.

In another interview with Stylist, Lipa said she uses a cleansing oil to remove her makeup at night before washing again with a cream cleanser and following with a probiotic serum and face cream. Moisturizing has become especially important since her career took off, she said.

"Traveling is the worst for skin, and it shows instantly," she told the outlet, adding that flying makes her skin especially dry. "Once you're working non-stop, you can instantly see it."
