Ariana Grande "can't believe" some of the beauty trends she used to "enjoy".

The Thank U, Next' singer believes it is a "beautiful thing" that she's been able to change her style and experiment with her appearance over the years but these days she would never even consider some of the looks she adopted in the past.

She told Bustle: "My make-up look has changed with me over the course of my life, but I feel like we are supposed to grow and try new things as we evolve.

“Sometimes I look back and I really can’t believe the beauty trends I used to enjoy — but I know that it is the most beautiful thing to not stay the same and to be able to learn new things and grow.

"We are all constantly learning and growing, so I know I’m not alone. To me, beauty should be about whatever feels most authentic and beautiful to you."

Ariana dyed her hair blonde a year ago for her role in 'Wicked' and admitted the colour change also made her overhaul her signature make-up look.

She said: "Since I’ve been blonde, and actually in the months leading up to blonde, I started experimenting more with different contouring and highlighting techniques than when I had my dark hair and brows, and definitely more subtle, natural eye looks.

"I’ve also started getting into iridescent products."

The 30-year-old star has learned the importance of looking after her skin, particularly after spending so much time in heavy make-up while filming or on stage.

She said: "The most important thing I have learned from both touring and from being on so many long, consecutive days on set over the years is to protect your skin. When you’re wearing make-up over long periods of time, if you’re not using the right products for your skin, it can really take a toll.

"I used to have really frequent breakouts when I was younger, working every day on set and using the wrong products.

"Making sure you have effective skin care ingredients in both your skin care and make-up routines is key to keeping your skin bright and healthy."
