Bachelor star Keira Maguire has detailed all the wild procedures she has undergone to maintain her age-defying visage. 

The reality-star-turned-influencer looks more than a decade younger than her 38 years, and appears to have aged backwards since her first foray into reality TV back in 2016. 

Speaking to Daily Mail Australia on Wednesday at a brunch to celebrate the launch of Naked Sundays new BeautyScreen Peptide Foundation Tint, Keira detailed the litany of cosmetic procedure she's had to shave years off her face.

From fractional lasers, Botox to minor filler treatments and salmon sperm injections, Keira has been into laser and injectables since she was in her 20s. 

'From a young age I had really bad acne scarring, so I'd get a lot of fractional lasers. Unintentionally, I fell into going to the clinic and getting a lot of facials,' she said.

'Actually, though, some of them took away from the natural collagen. So then I would find myself trying to get other facials to fix the other treatments that I've had. 

'I've had a lot of different hardcore lasers, like resurfacing lasers.'

During fractional laser treatments, a device with a laser beam divided into thousands of microscopic treatment zones is used on the face to help sun-damage and ageing skin. 

However, Keira said those treatments were just the beginning, as she was introduced to her first filler treatment when she was 25, and then later Botox at 30. 

'I got fillers in my lips when I was quite young because one of my ex boyfriend's mum got it for my birthday. She was like let's go get lip filler for my 25th birthday,' she said with a laugh.

'But I never got Botox until I was 30. The first time I got Botox was just before I went on the Bachelor [in 2016] and they did my jaw. 

'So I do look a bit different, but that's because that slims your face. So a lot of people say, "She's had so much work done." But I'm like no it's just lasers and Botox.'

Keira went on to say she doesn't use as much filler as her followers think, saying she only got the injections done once in her lips and lower cheeks. 

She explained earlier this year she had an RF fractional laser treatment done, three times within a 12 week period, and it 'melted the collagen' in her cheeks.   

'If you over laser someone, you can melt the fat in their face and the collagen... I had to get filler in the lower cheeks of my face [to fix it],' she explained.

Keira has also had Profhilo, a 'bioremodelling' injectable, and Rejuran, a salmon sperm facial which is also an injectable.  

'I had [the Rejuran] done three weeks ago. We did under the eyes. I definitely think the salmon sperm facial is the best thing I've ever had,' she said.

'I've had Profhilo. I don't like it. Rejuran is 100% the best thing on the market... I think it will replace filler.'

Keira has been very open about the procedures she receives, often posting about them on her Instagram page, but she often receives backlash over her appearance.

She said most critics complain she has 'too much filler' in her cheeks, despite her insistence that her plump features are natural. 

'I try not to put filler in my face. I just don't think you can reverse it... I don't believe in getting it. I've just never needed it,' she said.  

'I just say [to critics]... I don't have filler in my face and if I did I would tell you. You can tell when someone has filler in their face. You can feel it.' 

Keira rose to fame on Richie Strahan's season of The Bachelor in 2016, before appearing on I'm a Celebrity... Get Me Out of Here! and Bachelor in Paradise in 2017 where she met Jarrod Woodgate. 

The couple had an on-again-off-again relationship for about two years, before the couple split for good in late 2019.

Keira told Daily Mail Australia the pair no longer on speaking terms and Woodgate blocked her on Instagram.

Currently single, she moved back to her homestate of Brisbane after finding the dating scene in Melbourne boring. 

Keira has 126,000 Instagram followers, and regularly uses the social media app to promote brands and products.
