The former 'Love Island' star - who has teamed up with lingerie brand Boux Avenue for the company's new Your Shape, Your Style campaign to celebrate diversity and self confidence - has hit out at "airbrushed images in magazines" and revealed her own body positivity.
Alongside snaps from an official photoshoot, she said: "I've always spoken openly about body image, and how in my teens all I saw were airbrushed images in magazines - and that I thought it was how I was supposed to be.
"I remember it consuming me so much I obsessed day after day with calorie counting and trying to look like a size 0 model - whilst also losing myself in the process.
"I'm so glad to be working with Boux Avenue - a brand that represents women of all shapes and sizes."
The reality star - who rose to fame on the second series of 'Love Island' - previously opened up about battling an eating disorder.
Malin confessed she used to make herself sick after eating in order to remain slim and only stopped when she confided in her mum about her illness.
Sharing a photo, from her days as a flight attendant, on Instagram, she penned: "I wasn't born here, on this earth to starve. My mum didn't carry me for 9 months to watch her daughter fight an eating disorder for 8 years. The pain in her eyes when I told her I had been spewing my food wasn't worth being skinny.
"But it was. At that very moment, I didn't care who I hurt. I didn't care about hurting my body. I just wanted to be thin."
The brunette beauty explained how she spent the majority of her teenage years alone in her room obsessing over her weight, and is now determined to help others feeling the same as her to reach out for help.
She added: "Please understand this is why I am so passionate about body image, and why I flood your TL with it.
"I know there are so many of you suffering and I want to help ease that ... I have tagged some places to help. Try and reach out if you can. That's the first step to freedom."
