Kelly Rowland's top beauty tip is to "moisturise, moisturise, moisturise".
The former Destiny's Child singer - who has sons Titan, nine, and three-year-old Noah with husband Tim Weatherspoon - always wants to have "healthy, glowy skin" and knows keeping it hydrated is the best way to achieve a flawless complexion.
She told 'Entertainment Tonight': "I'm 43 now, and I've been in the spotlight and wearing makeup for over 20-something years of my life. I always think about what my skin is going to look like over time and how I can preserve and maintain healthy, glowy skin.
"The best beauty advice I've received is to moisturise, moisturise, moisturise. That's actually from Serena [Williams] and she's right!
"If you think about anything that looks really beautiful and refined, I don’t care if it’s wood or a plant, everything needs moisture."
While the 'Dilemma' hitmaker has an "easy" morning skincare routine, she spends a lot of time on her face in the evening.
She said: "My morning skincare routine is easy. It always has vitamin C and sunscreen. … In the evenings, I really take the time to pour back into myself because I always feel like the day takes all of your energy.
"I literally do the red light mask every night. … I swear by red light therapy. It is amazing.
"I also do three different cleansers, two different serums, a moisturiser, and Shiseido's Benefiance Wrinkle Smoothing Eye Cream.
"It helps me look like I got some rest, even if I didn't because I was up all night with my three year old."
Kelly loves experimenting with different beauty looks and she's delighted 90s make-up trends are back in fashion.
She said: "I like that we're actually revisiting some of the '90s make-up trends.
"You can leave the brows, it's not my thing, but everything else, like the way Naomi Campbell’s eye make-up was done in the '90s was just so fly.
"The fact that’s here is a big one for me."
