Susannah Constantine, 63, Reveals Skin Transformation After 17-Year 'Tweakment' Break

Susannah Constantine has unveiled her incredible skin transformation after undergoing her first ‘tweakment’ in 17 years.

The TV personality, 63, showcased the results of a bio-stimulating laser treatment after having the ‘realisation’ that looking after her skin wasn’t just about her vanity now she is reaching ‘midlife’.

The What Not To Wear star’s fresh new look comes a decade after she went sober following a long battle with alcoholism.

Susannah claimed her friends have noticed the difference in her quality of skin after trying Alma’s £350 Harmony Bio-Boost.

She said: ‘Reaching mid-life, I realised that looking after your skin isn’t just about vanity, it’s about vitality. I want my skin to reflect how I feel inside: strong, bright and healthy.

‘Even my friends started noticing the difference – not asking if I’d had anything done, just saying how fresh and well I looked.

‘That’s when I knew this was something special. I also noticed that I didn’t need to wear much makeup in my day-to-day life.’

The Harmony Bio-Boost treatment is believed to be suitable for those ‘looking to address skin laxity, acne, pigmentation and wrinkles’.

Susannah’s first ‘tweakment’ in 17 years comes after she tried Botox ‘a long, long time ago’.

The television personality’s latest procedure comes after she explained that a prescription drug her mother took when pregnant had a permanent impact on her looks.

Baring her teeth for the camera in October 2018, Susannah exposed the ‘grey tombstone’ teeth she was left with from birth.

The fashion guru explained how her teeth were permanently discoloured by antibiotics her mother took in pregnancy.

She said the drug tetracycline – commonly handed to mothers-to-be in the 60s and 70s – has had a lasting effect on her looks.

In a candid video posted to Instagram at the time, Susannah took the brave decision to show her teeth while asking for advice on how to deal with the problem.

The former What Not to Wear host told her 21,000 followers: ‘When my mother was pregnant with me she took an antibiotic called tetracycline.

‘And one of the side effects of taking that antibiotic was that the foetus would develop grey teeth throughout their life and as you can see my teeth are discoloured.

‘If anyone knows of a solution to these grey tombstones I would be really grateful to hear what you have to say.’

The antibiotic, designed to fight bacterial infections, was once prescribed for everything from sore throats and skin conditions to urinary tract infections.

But studies later discovered that when taken by pregnant women, the drug can become calcified in the permanent teeth developing under their baby’s gum line, discolouring them for good.

Later, when the baby teeth grow out, the tetracycline-stained ones move into position and reveal themselves. The unsightly stains can appear as yellow, grey or brown marks as well as white spots and translucent edges, with few solutions available.

Susannah said in a video called ‘Teeth! Oh what to do?’, which has been viewed almost 4,000 times: ‘You can’t get them bleached because what happens is the white parts get whiter and so the grey parts look greyer.

‘And I don’t want to get them bonded or veneered because I don’t like fake-looking teeth.’

One fan replied: ‘My hubs has the same thing from his mum taking antibiotics when pregnant. He will never smile for a photo properly, lips always shut.’

The Royal Pharmaceutical Society said tetracycline is no longer given to under-12s or pregnant women except in rare cases.

It is still used to treat acne and the sexually transmitted disease chlamydia.

Susannah’s mother Mary Rose, who suffered from manic depression, died in 2008 aged 76.

The TV star has described how the mental illness had an effect on her childhood as her mother was ‘in and out of psychiatric hospitals’ and made ‘several suicide attempts’.

Revealing a family history of struggles with booze, Susannah previously said on the on the ADHD Chatter podcast: ‘I was born an alcoholic, my mum was an alcoholic and my grandmother was an alcoholic.

‘I just say that alcoholism is a genetic disorder and it’s a mental disorder – drinking too much is a symptom and you might have the same gene.

‘Just be aware and if you’re worried, I’ve been through it, I’ve got the medal, come to me.’

Susannah, who is married to Sten Bertelsen, was very much an ‘It Girl’ in the 1980s, and even dated Princess Margaret’s son, David, Viscount Linley for eight years.

Susannah worked in America for designer Giorgio Armani before working for John Galliano in London.

The presenter met long-term pal Trinny Woodall in 1994 and they began writing a weekly fashion column, Ready To Wear, and founded Ready2shop.com.

They became famous for co-hosting the popular TV series What Not To Wear from 2001 to 2005.

She tied the knot with businessman Sten in 1995 and they share three children Cece, 20, Esme, 23, and Joe, 24, and have spent their three decades travelling the world.
