I look younger now than I did as a teenager after spending thousands on surgery and giving up meat and alcohol, people can't believe I have a son in his 20s

A woman has claimed she hasn't aged in decades thanks to spending  £86,000 to stay 'forever young'.

Marcela Iglesias, who is originally from Buenos Aires, in Argentina, but lives in Los Angeles, labels herself as 'human Barbie', appears to be ageless.

The 47-year-old, who has one million followers, has shared photos from over 30 years ago, when she was just 16 years old - and claims she hardly looks any different. 

Even people who haven't seen the businesswoman in years are left shocked when they meet her now. 

But this isn't just good genes, Marcela spends around £780 a month on IVs, wellness injections, vitamins and creams. 

She also has non-invasive cosmetic procedures to keep her skin looking smooth at least once a year. 

She said: 'When I meet people that I haven't seen in 10 or 15 years they can't believe that I look exactly the same or even 'better' than before.

'They are in awe of my wrinkle-free skin but it's not natural, of course. I have spared no expense to become a human Barbie. I have used the best doctors and injectors, and I'm very happy with the outcome. 

'My face is worth every penny. Gravity takes its toll so I'll keep fixing what I need fixing.' 

Staying forever young comes with more sacrifices than regular procedures. Marcela doesn't consume soy products, alcohol, fizzy or sugary drinks and eats a pescatarian diet. 

She exercises for at least an hour a day and always gets eight hours sleep per night. 

The human 'Barbie' also credits her glowing skin not only to Botox, but to staying hydrated with a very powerful water filtration system. 

She said: 'I feel great – in fact, I feel more confident in my own body right now than when I was in my early 30s. 

'When people find out I have a 23-year-old son [Rodrigo], they say I am far too young to be a mum.' 

Marcela considers cosmetic procedures key in maintaining her look. 

She said: 'In other parts of the country, people might judge you for having surgery, but I live in Los Angeles – the land of surgery. 

'I refuse to feel ashamed about using modern methods to keep myself looking good. 

'People might call me plastic or fake, but I don't care.' 

Marcela's journey with beauty enhancements first began 12 years ago. Since then, she has had countless non-surgical procedures, as well as gone under the knife for a boob job, cellulite treatment, muscle toning and had skin treatments to restore her hands. 

Her son, Rodrigo, has been inspired by his mum, too – with Marcela 'gifting' him a nose job for Christmas a few years ago. 

These days, she mainly focuses on non-invasive procedures such as biotech's and fillers. 

Marcela finds people are desperate to know exactly what she does to stay looking so young. 

She said: 'I have to tell them the truth – even though they may do all the treatments that I have done, sometimes plastic surgery is the only solution. 

'It feels great that people recognise the work that I have put in. Everything that you put in your body will reflect on the outside so it's very important to treat the inside as well as you can, too. 

'That requires a lot of sacrifice and most people don't want to do that.' 

The influencer isn't done yet, either. She is in consultation with a surgeon to get £12,000 butt implants. 

Marcela added: 'The surgery is very simple, but the recovery is a little bit difficult because you can't sit down for at least three weeks, so I have to think it through very well. 

'I feel my butt could be more round and curvy and have more projection that you can admire more from a profile. 

'These procedures are not to fix anything but more of an improvement – and if I can afford them, why not do it?'
