Top dermatologist's urgent warning to those with spots - common remedy could leave you scarred for life
Popping an unsightly pimple before a big social event or work presentation may seem like a simple solution.
But while this might seem like a good idea at the time, it's a bad habit that can do more than just scar you, a skin expert has warned.
According to Dr Conal Perrett, a dermatologist at The Devonshire Clinic on Harley Street, London, popping spots can risk spreading infection or requiring pricey follow-up care, often costing hundreds of pounds, to fully clear.
Instead, he suggested targeted treatments and gentle skincare to support natural healing for spots.
Acne is one of the most common inflammatory skin conditions in adolescents. More than 80 per cent of teenagers battle with pimples.
The condition is caused by hair follicles becoming plugged with oil or dead skin cells, which can be a result of shifts in hormones, or using cosmetic products and certain medications.
It can also occur later in life for a number of reasons.
Dr Perrett advised: 'Refrain from picking or squeezing any blemishes, as this can worsen inflammation and lead to permanent marks.'
The correct way to treat a troublesome spot depends on the type you have, the doctor warned
'For stubborn scarring, advanced treatments such as chemical peels, laser and microneedling can be the best way forward.'
'Using the right skincare ingredients, alongside daily sun protection, can make a significant difference.
'For more persistent or severe acne, seeking professional advice is the best way to protect the skin and support a smooth, healthy complexion in the future.'
Dr Perrett also urged people, in particular acne sufferers, to look out for the five main types of spots: blackheads, papules, pustules, nodules and cysts.
Dark spots on your face are likely blackheads, Dr Perrett noted, which can be treated and prevented with products containing salicylic acids and gentle retinoids—because they keep pores clear.
Such products are available on the high street, often as serums.
Small, red inflamed bumps without visible puss-filled heads, meanwhile, are likely papules—which occur when clogged pores trigger deeper inflammation.
This redness can be reduced by products containing benzoyl peroxide, niacinamide, topical retinoids, alpha hydroxy acids and azelaic acid.
Spots that look similar to papules but have a red base and white or yellow tip, are likely pustules which carry a higher risk of scarring if popped.
These troublesome spots can be treated with the same way as papules, but in some cases prescription-strength retinoids and oral antibiotics may be needed.
Another, nodules, are large, painful and sit deep within the skin.
These have a significant chance of leaving permanent scarring, so they also require prescription-strength retinoids and oral antibiotics.
Cysts, meanwhile, have the highest likelihood of scarring and are large, soft, pus-filled lumps that sit deep below the skin's surface.
'It is crucial to never squeeze cysts, as this can dramatically increase scarring and spread infection,' Dr Perrett warned.
If patients have painful cysts and nodules, steroid injections such as corticosteroid to quickly reduce swelling, redness and pain.
However, he added, if pimples stubbornly persist patients should see a dermatologist.
For those with acne scars he said wearing a hydrating SPF can, minimise how visible they are.
'Sun exposure stimulates melanin production, which can make scars appear darker and more pronounced,' he said.
'A broad-spectrum sunscreen with SPF 30 or higher should be applied every morning and reapplied throughout the day.
'Pairing sun protection with a good moisturizer enhances skin repair by maintaining hydration, which is crucial for cell turnover and barrier function.'
This is especially important for those taking the acne medication Roaccutane, as it makes them more sensitive to ultraviolet radiation from the sun, he warned.
Research has suggested diet may also play a role in acne prevention.
Experts advise avoiding sugar and focusing on a healthy, well-balanced diet with high amounts of nuts, legumes, fish, red meat, fruits and vegetables.
Some studies also suggest there is a higher risk of acne with frequent milk consumption, but more research is needed before dietary recommendations can be made.
For this reason, experts recommend keeping a diary to see if any of foods directly aggravate acne and avoid them if this is the case.

Major supermarket urgently recalls lunch favourite that's contaminated with 'pieces of plastic'
A batch of pre-cooked chicken pieces has been urgently recalled due to the presence of plastic in some of the packets—causing a huge choking risk. BM Foods Ltd has issued an urgent recall on their Chicken Cooked Meat Trimmings, which are sold at budget supermarket Aldi. The recall affects the 400g products with the use by date July 4, 2025 and the batch code 50328453. Customers who have a packet of the contaminated meat have been told to not eat it, and to return the product to their Aldi store where they will receive a full refund. In a statement Aldi said: 'As a precautionary measure, our supplier is recalling selected packs of Chicken Cooked Meat Trimmings because they may contain plastic. 'We apologise that this product did not meet our normal high standards and thank you for your co-operation.' The Food Standards Agency (FSA), the UK's regulatory body for food and drink, issues recalls when problems are spotted with food that could be potentially harmful to consumers. In the urgent recall, the FSA said: 'The possible pieces of plastic in the products presents a choking hazard and makes them unsafe to eat.' It came just days after the budget supermarket issued an urgent recall on Inspired Cuisine Baby Potatoes with Herbs and Butter with the pack size 385g. This was because it contained milk not mentioned on the label—which poses a possible risk to anyone with an allergy or intolerance to milk. The food safety watchdog told the supermarket to contact the relevant allergy organisations to inform their members. Customers were similarly asked to return the product to their nearest Aldi store to receive a full refund. They warned those who have bought the product and have an allergy or intolerance to milk or milk constituents, not to eat it. It included Inspired Cuisine Baby Potatoes with Herbs and Butter products with date codes up to and including July 1, 2025. The supermarket also issued a 'point-of-sale notice its customers', which explains the recall and instructs shoppers on what to do next. 'These notices explain to customers why the product is being recalled and tell them what to do if they have bought the product,' said the regulator. While cow's milk allergy is less common in older children and adults, it affects about one in 50 infants in the UK, according to the NHS.

Carers like me connect patients and doctors – so why are we so often made to feel invisible?
It's autumn 2024 and I'm talking to an A&E doctor. We're on the refreshment break at a conference about care. He tells me that he and his colleagues keep their NHS lanyards visible when they take loved ones to medical appointments. It means the doctors listen to them. It's understandable; they're peers with shared training and expertise. But it's also infuriating because I know Mary's story and many more like it. Mary is 58, and lives in Wales with her husband and their adult son. As a result of epilepsy in infancy, her son has global developmental delay. Practically, this means that he is non-mobile, non-verbal and takes food through a tube to his stomach. I worked with Mary and 15 other unpaid carers last year, supporting them to keep weekly diaries and interviewing them, resulting in a research report. Mary's son requires medication to prevent excess drooling. He can't stop himself choking, so it's essential to minimise his saliva production. But in her diary, she explained that the medication was changed and the new type was less effective – he was having dangerous coughing fits. Mary reported this to his medical team but, in her words: 'It was a feeling of, if it wasn't witnessed by a health professional it didn't happen.' A few weeks later, she had a meeting in her home with some of his care team. 'I was just lucky that he performed,' she told me with a wry, tired smile, by which she meant he had a coughing fit in front of the professionals. His medication was swiftly reverted. I wish Mary's story was unique. But it's not. Ada is 80 and also cares for her son. He's in his 40s, and has autism and several other conditions. She had been warning medical professionals about his escalating panic attacks for months, but nothing had been done. In one incident, he became so panicked that he ran away from his daycare centre and had to be located by police. At other times, when it's just Ada and him at home, things can turn violent. Still, Ada told me that her concerns were dismissed. She was only believed when, by chance, a psychiatrist happened to witness one of these panic attacks. 'He said it was one of the gravest attacks he had seen.' To be an unpaid carer is to be deemed not credible, according to Mary, Ada and several other carers in this study. Mary feels this is especially apparent higher up the professional ladder. The community-based staff listen to her, perhaps because they see what she does for her son on a daily basis. But of consultants and doctors, she said: 'I'm lucky if they'll even look at me.' Yet it is Mary who has been at every medical appointment for her son during his 26 years. It is Mary who spends 15 hours in every 24-hour period providing care for him (alongside her part-time job and the paid care he receives). It is Mary who spots side effects, monitors symptoms and administers medications. It's not just about feeling respected; for carers such as Mary and Ada, being heard is a matter of life, death and safety. Of that meeting at which her son 'performed', she wrote that there had been too few chairs to seat all the attenders, so she perched on the periphery. 'The irony that there was no room for me at the table was not lost.' Family members provide far more than hands-on care at home in the absence of paid workers – their unpaid labour is woven through the entire health and care system and at all times. At the most basic level, they perform a high volume of administrative tasks, made harder by disjointed and complex systems. In fact, the carers in the study spent up to 220 hours over 12 weeks on these sorts of tasks for the people they are caring for. The diaries read like broken records – endless arranging and rearranging of appointments, prescriptions and finances, automated phone services that lead to dead ends, digitised forms that aren't fit for purpose. 'I wish that we did not move in circles,' wrote Philippa, 86, and caring for her 60-year-old son, after a long week trying to sort out his future care. In a cast of changing medical and care professionals, family members also act as essential living repositories of their loved ones' medical histories. Jared's wife had an industrial accident in 2011, after which she was in a coma. Jared told me that her medical notes were about 900 pages long. Medical professionals have rarely, if ever, had time to read all of the notes. In this context, Jared becomes indispensable as 'the only one who can say, well, this happened in this order'. Beyond project management and medical histories, carers also reported enabling what professionals call 'person-centred care', ensuring that the personality and preferences of their family members are understood. Lisa's mum is 75, and has diabetes, multiple sclerosis and cognitive decline. She is supported by a live-in paid worker. Lisa settles in the paid workers when they rotate. She does this practically – showing them where things are in the house – but she also communicates 'the nuances of Mum … I want to get across to them that they are going to see the worst side of her, but she's not that.' She tells them about the dinner parties her mother used to throw, her flirtatious and bubbly nature. 'She's such a different person now that you want her care workers to understand who she was.' Throughout the interviews and diaries, carers such as Lisa explain repeatedly how they lubricate the system, enabling it to function when care-receiving loved ones cannot. They are the unseen but essential lifeblood of the health and care system: it's not about them, but it does not function without them. Since being a carer myself, and subsequently writing a book about carers' experiences, I have developed a keen sense for when a policymaker, politician or simply a member of the public has failed to understand the contribution of carers. The Labour party manifesto last year was a case in point. It managed to set out a plan on care yet omit carers, that is, the people who perform the vast majority of care in the UK. Subsequent governmental announcements fall into the same trap, paying carers cursory attention. While we wait for politicians to catch up with reality, perhaps carers need to pirate those NHS identity cards. I'm not serious, of course. But I think, too, of Mary, Ada and all the other carers I've met, walking a tightrope of their loved ones' safety on a daily basis, steeped in loving and practical knowledge. It shouldn't take a piece of laminated card for them to win legitimacy.

Fragile Minds by Bella Jackson review – a furious assault on NHS psychiatry
In 2018, Christie Watson's memoir about what it means to be a nurse became a publishing sensation, spending more than five months in the bestseller lists. The Language of Kindness: A Nurse's Story was tenderly distilled from the two decades that Watson had worked for the NHS, capturing the essence – and importance – of what it means to care for patients. Counsellor Bella Jackson will presumably be hoping that her account of two years spent training as a mental health nurse will resonate in a similar way. Jackson worked in social care for five years before embarking on her nursing degree. The book is 'pieced together from scattered notebooks and scribble'. But from the outset, it is not entirely clear what is fact and what is fiction. She explains that she has constructed three 'composite' settings from her contemporaneous notes: an acute psychiatric ward, an A&E department and a community psychiatric team. Although based on real situations, the stories she tells are also composites in which names and identifying details are changed. Similarly, the healthcare professionals depicted are 'generic'. The verisimilitude of what is described matters greatly because it is used by Jackson to mount a furious assault on the failings of modern psychiatry. The gross underfunding and understaffing of NHS mental health services is, she argues, 'only half the story. The other half is messy and confronting. It is philosophical and systemic. It is uncomfortable enough to make us look away sharply.' Without spelling out exactly what she means, she sets out to document the messiness unflinchingly. Entering the ward on day one triggers a powerful childhood memory. As a six-year-old child, Jackson accidentally locked herself in a bathroom while her parents hosted a raucous party. Recalling the overwhelming panic and powerlessness of being incarcerated causes her to reflect on the ward patients' plight: 'It's easy to walk in and out of a locked ward and forget the significance of that power. Does The Door protect the vulnerable people inside from an unkind world? Or does it protect our fragile society from the people who embody its failings?' Jackson's answer to this question is emphatically the latter. Seen through her eyes, locked psychiatric wards are bleak, punitive places patrolled by staff who are – with only rare exceptions – at worst cruel and at best indifferent. In the first few pages, psychiatrists are set up as uninterested, inhumane, work-shy pill-pushers. A patient spends hours hovering by the door, trying hopelessly to catch the eye of the consultant psychiatrist as he 'flitted in and out, always with somewhere else to be'. When another patient recounts a harrowing tale of homelessness and childhood beatings, the same consultant merely shuffles his papers as if the patient 'were absent'. Nurses are, if anything, even worse. A particularly aggressive nurse called Leon tells Jackson that he hates the ward because 'these patients get away with anything they want … asking what this is, what that is. What the fuck?' Two healthcare assistants laugh together about forcibly injecting patients with rapid tranquillisers. Amid the racist, abusive and offensive staff, who mock, belittle and chemically cosh their patients, are individual tales of heartbreaking social and psychological circumstances. Patients have experienced sexual assault, childhood abuse, domestic violence, poverty, exclusion and multiple suicide attempts. All of this is ignored by staff. High doses of antipsychotics leave the patients drooling and gurgling. One man has the face of 'a tired waxwork' while others 'remained shapes against the blank walls'. Jackson finds herself frequently intervening to stop a trigger-happy nurse or doctor casually slapping a potentially life-changing diagnosis such as psychosis or bipolar disorder on to a distressed patient. The problem with this account, for me, is that it doesn't really resonate with my experience. I spent my first rotation as a junior doctor in psychiatry at the same time Jackson was training. I simply didn't see the kinds of abuses Jackson documents – despite being a former current affairs journalist who was, and remains, highly attuned to the power dynamics inherent in medicine and potential injustices against patients. A particularly extraordinary moment is when Jackson describes a nurse telling her about a junior doctor 'who used to legit say, 'Let's quetiapine them today!' And I asked him why quetiapine, and he said, 'They put you in the best hotels for conferences.'' Really? That kind of pharma corruption was rooted out long ago – and I can scarcely imagine a junior doctor of my era using such a ludicrous phrase. Jackson has sacrificed complexity for polemic. The crux of her argument is: 'The medical world doesn't really know what to do with distress, so we drug the person, because that's what the medics are taught to do.' But the truth is not this simplistic. Psychiatrists do indeed have an almighty power to do things to patients that in any other context would be considered human rights abuses – restraining them, injecting them with drugs, depriving them of their liberty. Yet this is because the most seriously unwell patients often have no idea they are ill and will not engage with treatment voluntarily. Sectioning a patient is a last resort, not a cavalier act of malice. And though talking therapies are desperately lacking, this is due to endemic underfunding, not because psychiatrists regard them as pointless. Most of the psychiatric nurses and doctors I worked with were decent, run ragged, and longed to be able to offer their patients more. The truth is, we still understand very little about the root causes of serious mental illnesses and are painfully aware of what blunt tools psychotropic medications are. Jackson implies that treating serious mental illness is simply a matter of listening to, believing and empathising with patients. If only this were true for bipolar disorder and schizophrenia. There is much to be fixed in NHS psychiatry, but I'm afraid this book feels like scaremongering.
