Does red light therapy work? Experts weigh in on TikTok skincare trend
⭐️HERE'S WHAT YOU NEED TO KNOW⭐️
A new skincare trend called red light therapy has been all over TikTok.
Fans of red light therapy claim it makes skin look clearer, smoother and younger.
But some experts say the trendy treatment is probably not as effective as it seems.
Read on to find out what they said. ⬇️⬇️⬇️
Can a special kind of light make your skin look smoother, clearer and younger?
That's what a host of TikTok skincare influencers have been claiming recently in videos about products that use something called red light therapy.
But there is a long history of beauty products making false claims about what they can really do in order to maximize sales.
With this in mind, CBC Kids News talked to two doctors who specialize in skin about red light therapy. They said the technique does have some benefits, but they wouldn't recommend it as a first option for kids and teens.
What is red light therapy?
Red light therapy has been around for decades, according to Dr. Monica Li, clinical assistant professor in the department of dermatology and skin science at the University of British Columbia.
It involves shining low-level light on the skin using large machines in specialists' offices, or at-home devices like facemasks, lamps and wands.

'The idea is that low-level or red light can trigger a chemical reaction in your cells that gives them more energy, potentially reducing cell damage and promoting better cell function,' Li told CBC Kids News.
Does it work?
Li said that the most science-backed benefit of red light therapy is its ability to reduce inflammation and redness.
'If used consistently, red light therapy has been shown to reduce inflammation on the skin, particularly for conditions like rosacea and acne.'
However, Li said evidence for claims that red light therapy has anti-aging benefits isn't as strong.
'There are claims that red light therapy can reduce lines and wrinkles through, for example, stimulating collagen growth,' she said. 'But the science there is lacking.'

Part of the issue, says Dr. Julia Carroll, a dermatologist and lecturer at the University of Toronto, is that the science behind red light therapy is based on in-office machinery that is a lot more powerful than the at-home devices most people are seeing on TikTok.
So even if there are anti-aging benefits, it's difficult to say how effective at-home treatments are.
Both experts also said that seeing benefits requires using the devices consistently over a long time, which many people have difficulty with.

Would you recommend red light therapy for kids and teens?
Both of our dermatology experts said no.
That's because its main science-backed benefits are for conditions like acne, which have many other treatment options they would consider before red light therapy.
'If someone has acne, they should talk to their parents and see their doctor because there are more tried-and-true, less expensive options that are effective and safe,' said Li.
Carroll agreed, and said red light therapy would be 'overkill' for kids and teens.
Instead, she recommends starting with a good skincare routine and going from there.
'If you really have a problem, you want to seek a medical opinion from a dermatologist. You can probably get better results with a lot less money and effort,' she said.
Safety of red light therapy
Both Li and Carroll said there isn't any harm in trying red light therapy if you really want to.
As far as skinscare treatments go, they said it's pretty safe, especially compared to some harsh chemicals used in other skincare fads.
However, if you do try it, Li recommends using eye protection.
'The potential risk is eye damage or retina damage, especially if someone is repeatedly exposing their eyes directly to the red light,' she said.

Pistachio recall tied to viral chocolate bar reflects salmonella risks from nuts
More brands of TikTok-famous chocolates with pistachios have been recalled over salmonella concerns, with food scientists saying the nuts can be prime suspects for causing outbreaks of foodborne illness. On Thursday, the Canadian Food Inspection Agency said more types of Dubai pistachio and knafeh milk chocolate have been recalled (new window) , following earlier recalls of Habibi brand of pistachios or deserts like baklava containing the nuts. People should not eat, serve or cook with any of the affected brands (new window) . The Dubai chocolate craze for milk chocolate bars filled with a pistachio cream and crunchy pieces of knafeh was fanned by food bloggers. But recalled pistachios and pistachio-containing products (new window) are now linked to 52 illnesses between early March and mid July, including 10 hospitalizations (new window) across Canada. "We know that cases in the outbreak have the same genetic fingerprint in the strain of salmonella that made them sick, and this same strain has been found in the Habibi pistachio (new window) brand," said Anne Marie Lowe, outbreak manager at the Public Health Agency of Canada in Montreal. What caused this outbreak isn't yet known and may stay a mystery, food scientists say. But because the nuts have a long shelf life, it may not be over soon. Pistachios shaken from tree Salmonella infection is a food-borne bacterial illness (new window) that may cause fever, headache, vomiting, nausea, cramps and diarrhea. It's caused when fecal material from infected humans or animals gets into our mouths, such as by consuming contaminated food or drink. The bacteria live in the intestines of many animals and common sources include undercooked poultry and other meats, undercooked eggs and unpasteurized milk. For pistachios and foods containing the nuts, contamination can happen before or during harvest (new window) as well as processing, said Lawrence Goodridge, who holds a Canada Research Chair in foodborne pathogens. Pistachios grow on trees and before harvest, birds and insects can introduce salmonella to the nuts, he said. Contaminated irrigation water is another possibility. To harvest pistachios, the trees are typically shaken, including with mechanical equipment. The nuts fall onto trays that can be contaminated in the orchard, Goodridge said.

Photo: Associated Press / Damian Dovarganes Salmonella in chocolate resists stomach acid While cooking contaminated chicken or eggs kills salmonella, some pistachios in products are raw, and even cooking the nuts may not do the trick. One of the issues with salmonella is it survives very well in dry foods, Goodridge said. "It may not grow, but it will survive for very long periods and that's why we've seen outbreaks in dry foods like pistachio nuts and almonds, chocolate (new window) and flour (new window) ." Microbiologist Keith Warriner, a professor specializing in food safety at the University of Guelph, said some salmonella subtypes, such as the Havana serotype implicated in this outbreak, can persist in soil. "An additional factor is that when incorporated into chocolate (new window) , the salmonella can survive the stomach acid so relatively low doses are required to cause illness," Warriner said. Enlarge image (new window) People are advised not to consume, use, sell, serve, or distribute the recalled baklava products. Photo: Agence canadienne d'inspection des aliments/Canadian Food Inspection Agency In this outbreak, the pistachios were imported. Goodridge said investigators typically look at who imported the foods and their records to ensure the ingredients or foods were produced to the same standards as in Canada. Boutique or artisanal products aren't more or less safe in and of themselves, Goodridge said. One thing that consistently has occurred in outbreaks … is that oftentimes there's a breakdown in terms of the food safety programs that should have been followed, he said, pointing to last year's plant-based milk recall and Listeriosis outbreak (new window) that killed three people. Another factor that could extend this salmonella outbreak is that if pistachios are dried, the shelf life (new window) can be up to two years, depending on how they're stored, Goodridge said. WATCH | Do more recalls mean safer food? The outbreak investigation continues, Lowe said, and other affected food products could be identified. The delay between when a person becomes sick and goes to the hospital to get tested and the time when the case gets reported to public health is another factor in extending outbreaks, she said. Warriner has an eye on preventing salmonella illnesses. Since salmonella persists under dry conditions and pistachios are dried after harvest, he said, thermal treatments may not work. He's working on a way to pasteurize nuts that doesn't involve heat. If pistachios are dried, the shelf life can be up to two years, scientists say.

He felt 'chased' by anxiety and got help online. Now, that resource experts trust could be shut down
Joey Laguio remembers waking up every morning in high school with a sense of dread. It felt like always being chased by something, said Laguio, now 33 and living in Vancouver. After he enrolled in engineering at the University of British Columbia, his first major panic attack hit. Breathing was hard and he trembled, consumed with worries over what others thought of him, he said. From a counsellor in Vancouver, Laguio learned that he had anxiety, and was referred to Anxiety Canada (new window) , a registered charity offering resources online for people with anxiety and obsessive compulsive disorder (OCD). The specific resources were helpful to me because I could access them at any time I wanted to and also because they were a good complement to the therapy I was doing, Laguio said. Now, however, some mental health experts are worried Anxiety Canada's online resources will cease to be available next April if the organization that had funding cut by the B.C. government earlier this year doesn't find a new source of revenue. They say patients, families and mental health professionals will lose a carefully curated and trustworthy source for mental health information, tips and tools just as misinformation proliferates. 'Worried about what's going to happen' Dr. Julie Eichstedt, a child psychologist in London, Ont., said although anxiety disorders are very treatable, access to resources is a concern. I'm worried about what's going to happen to all those people that have been dependent on these [Anxiety Canada] resources, Eichstedt said. There's really nothing compatible for me to send families to. Enlarge image (new window) Linda Campbell, left, and her son, Ryan Campbell, turned to Anxiety Canada for help several years ago after a suggestion from a child psychiatrist. Photo: CBC Linda Campbell of Nanoose Bay, on Vancouver Island, said she was caught by surprise several years ago when her outwardly happy son told her one day when he was in Grade 3 that it was all too much. Campbell initially equated anxiety with stress and overscheduling her son. Then they found a child psychiatrist who suggested Anxiety Canada. I knew I could trust it, Campbell said. Every health-care provider said go here because we know what you're going to get, so we have a framework between us to have conversations. I don't think I even realized the importance of it at the time. About one in four people will deal with levels of debilitating anxiety at some point in their lifetime, leaving them unable to work at their full capacity, said Maureen Whittal, a psychologist who co-founded Anxiety Canada in 1999 and is chair of its volunteer board. Socially, anxiety can interfere with relationships, including marriage and parenting, she said. Increases in generalized anxiety disorder Statistics Canada says generalized anxiety disorder doubled among those aged 15 and older between 2012 and 2022, rising from 2.6 per cent to 5.2 per cent. Young women 24 and under showed the largest increases. Anxiety Canada saw $223,200 in provincial funding removed earlier this year and scaled back its services. It is now a skeleton organization relying on a few volunteers but no paid employees. Its MindShift app, which was shut down when the funding was removed, had more than 1.5 million downloads in 2024, with tens of thousands of monthly users, including teens. A published study (new window) showed use of the app reduced anxiety and stigma and Whittal hopes it could resume if further founding is found. Some of Anxiety Canada's online resources continue to be available as it winds down its services. Campbell, who is a member of a support group for parents whose children have anxiety disorders, said people will grasp onto what they think will offer quick and easy solutions. They're kind of in a desperate moment and they think that this will solve their problem, she said. I think that's why it's really important to say: 'Here's what we know is proven techniques.' Laguio says he started his mental health journey with professionals 12 years ago. Photo: Matthew Fong Earlier this year, Anxiety Canada also wound down its educational podcasts and TikTok videos modelling best practices and cut an online cognitive behaviour treatment program as its funding was reduced. Eichstedt said she recommends Anxiety Canada to parents and teachers because all the evidence-based content and practical examples are in one place, setting it apart from other services. Guide to effective treatments For children, avoidance behaviours are one of the hallmarks of anxiety, Eichstedt said. They may miss school, not participate in class or make friends. Marks can go down because the student is afraid to ask for help or can't complete their homework. There may be lots of tears, there could be tantrums, Eichstedt said. But left untreated, anxiety tends to persist and can fuel other problems like depression. Treating anxiety is important to make sure kids develop as they're supposed to, she said. WATCH | Overcoming the stigma around mental health struggles: Robert Roopa (new window) , a psychologist and psychotherapist in York Region, north of Toronto, said he often refers to Anxiety Canada's articles and videos. If the site is no longer available, I'm concerned that an increasing number of people who need OCD and anxiety support will not receive the appropriate treatment, Roopa said. Then the patient loses time and money on what doesn't help their specific problems. Filling a 'critical gap' Dr. Peggy Richter, a psychiatrist in Toronto who heads the Frederick W. Thompson Anxiety Disorder Centre at Sunnybrook Health Sciences Centre, says that ideally, people would see a live therapist for help. But we recognize across Canada with our geography that that [isn't] always feasible and people with expertise in how to treat the anxiety disorder psychologically are very often very hard to find covered by OHIP or provincial health-care systems, said Richter, who also specializes in OCD. MindShift was filling a really critical gap. The B.C. government's Mental Health and Substance Use Services (BCMHSUS), which provides specialized services in the province, said it issued a contract this year worth about $1 million to BC Partners. Anxiety Canada had been of member of the partners, a group of mental health and substance use organizations, but was no longer included by the government this year. The 2025/26 funding is half of the $2 million given the previous year, BCMHSUS said. While this is less than last year's contract, it is a substantial contribution to health literacy. The other funds were directed towards critical front-line services supporting the care and recovery of people with mental health disorders. Maureen Whittal says Anxiety Canada's mission is to provide evidence-based psychological resources to help people and their families. Photo: CBC B.C.'s Health Ministry said its relationship with Anxiety Canada through BCMHSUS ended earlier this year. No further provincial funding will be available for Anxiety Canada for the next fiscal year, beginning in April. To revert to full service would take $1 million annually, Whittal said. Eichstedt is organizing a letter-writing campaign to try to save the now volunteer-run group. She'd like to see federal funding for Anxiety Canada as a national resource and program for anxiety and related disorders. Laguio, the Vancouver resident, said Anxiety Canada complemented the cognitive behaviour therapy sessions his parents paid for with a psychologist. As a teen and young adult, Laguio said he dreaded even the thought of driving. I would have existential crises of like: 'What if I what if I hurt someone or like someone's life ends because of me?' LISTEN | Trying to get people to talk about OCD (new window) Some days he'd stick with what he called a two on a 10-point fear scale of Anxiety Canada's fear ladder exercise, where you list actions you'd typically steer clear of and then slowly work through them. For him, it started with driving around a quiet block at night. Now, Laguio calls the cognitive behaviour therapy received through Anxiety Canada foundational to managing his relationships and work. Laguio said as a non-profit, he felt Anxiety Canada had his best interests at heart. It was free, he said. As someone who was really struggling with my career and finances, that's kind of what I needed.

Toronto surgeon dies while competing in triathlon in Barrie
Dr. Sean Cleary is seen in this undated photo released by the University of Toronto. (UofT handout) Members of the city's medical community are mourning the loss of a Toronto surgeon who died while participating in a triathlon in Barrie over the weekend. In a statement released by the University of Toronto, Carol Swallow, the chair of the department of surgery at the post-secondary institution, confirmed that Dr. Sean Cleary, the Langer chair of the division of general surgery, died while taking part in a triathlon north of Toronto on Sunday. 'Sean has touched the lives of many of us – as a clinical colleague, a teacher, a mentor, a supervisor, a confidential advisor, and a friend,' Swallow's statement read. She described the late doctor as a 'reliable, wise, honest, insightful, and compassionate' leader who had a 'perpetually wry sense of humour.' 'I am struggling to accept what has happened,' the statement continued. 'I suspect many of you are feeling a similar sense of shock and denial at this point, and that the profound dimensions of this loss will gradually become apparent over the coming days and weeks.' Barrie police told CP24 Thursday that a 52-year-old man who was taking part in the event was removed from the waters of Kempenfelt Bay shortly after 8:30 a.m. on Sunday after 'going into medical distress.' 'Although lifesaving efforts were initiated, he was pronounced deceased at a local hospital,' police said in an email. A 'shared sense of loss' Swallow said Cleary dedicated much of his professional career to the division of general surgery and the department of surgery at U of T. 'He trained here as a general surgery resident, and then as an HPB (hepatopancreatobiliary) surgical fellow. He graduated from the University of Toronto Surgical Scientist Training Program with an MSc degree in cancer genetics,' Swallow's statement read. 'Straight out of fellowship, Sean was recruited to the University of Toronto Department of Surgery as an Assistant Professor and joined the surgical staff at University Health Network with an appointment as an HPB surgical oncologist at Princess Margaret.' She noted that he developed his own research program in cancer epidemiology and was quickly promoted to associate professor at the university. After leaving for a position at the Mayo Clinic in Rochester, New York in 2016, Cleary returned to Toronto in 2023 to serve as the Bernard and Ryna Langer Chair of the Division of General Surgery at the University of Toronto. 'I wish Sean had had more time to fully deliver on this vision but recognize that much has already been achieved,' Swallow's statement read. She noted that resources are being offered to faculty and learners who are grieving the loss. 'As a surgical family, we express our shared sense of loss and our sincere condolences to Sean's own family,' the statement continued. 'We have all lost a fine human being whose like we will not see again.'
