The best nontoxic nail polish of 2025, according to a celebrity manicurist
Especially since these products have become just so good. In the past, nontoxic nail products have been inferior in almost all ways to their chemical-jammed counterparts — swiping on streaky with bland color options and annoyingly short wear times. But innovations in nail care mean you can now find safer polish alternatives in a range of coveted shades and — as with my top pick from Dazzle Dry — with sturdy and long-lasting finishes too.
Over the past few months, I consulted with some true nail pros and tested more than a dozen nontoxic nail polishes (and a handful of nontoxic nail polish removers). The following are my expert-approved picks for the best of the year.

I consulted with nail technicians along with TikTok and Reddit threads and hundreds of Amazon reviews to identify the top dozen nontoxic nail polish brands. I tried them on my own nails and rated them on ease of use, dry time, pigment quality, value and how long each lasted without chipping.
I tried Gucci's extremely fancy, $35 nontoxic polish and found it to be not only not very nontoxic (it barely cracks 3-free) but also streaky and hard to apply. Similarly, the pigments in Essie's nontoxic Love line were extremely weak.
Nontoxic nail polishes are categorized by the number of harmful chemicals their formulas exclude. While most nail pigments have been 3-free (meaning they're made without dibutyl phthalate, toluene and formaldehyde) for the past decade or so, today there are loads of options ranging from 5-free all the way up to 15-free. Since there's no government oversight on most cosmetics, we don't really know what all this means, but if you're looking for the best nontoxic nail polish, go for a higher "free" number or, in the case of two of our picks above, those that are completely chemical free.
Most experts I spoke with suggest seeking out products that are 5-free or higher — my top pick from Dazzle Dry is 14-free and there are loads of options that are plant-based and vegan.
Though there's usually no set expiration date, due to a lack of chemical preservatives, nontoxic nail polishes will most likely expire at least slightly more rapidly than regular nail treatments. If you notice the product has separated, even after you shake it, it's probably time to give it a toss. Even if an expired nail polish is not harmful, it will be less effective and your color will appear uneven.

What happens when chatbots shape your reality? Concerns are growing online
As people turn to chatbots for increasingly important and intimate advice, some interactions playing out in public are causing alarm over just how much artificial intelligence can warp a user's sense of reality. One woman's saga about falling for her psychiatrist, which she documented in dozens of videos on TikTok, has generated concerns from viewers who say she relied on AI chatbots to reinforce her claims that he manipulated her into developing romantic feelings. Last month, a prominent OpenAI investor garnered a similar response from people who worried the venture capitalist was going through a potential AI-induced mental health crisis after he claimed on X to be the target of 'a nongovernmental system.' And earlier this year, a thread in a ChatGPT subreddit gained traction after a user sought guidance from the community, claiming their partner was convinced the chatbot 'gives him the answers to the universe.' Their experiences have roused growing awareness about how AI chatbots can influence people's perceptions and otherwise impact their mental health, especially as such bots have become notorious for their people-pleasing tendencies. It's something they are now on the watch for, some mental health professionals say. Dr. Søren Dinesen Østergaard, a Danish psychiatrist who heads the research unit at the department of affective disorders at Aarhus University Hospital, predicted two years ago that chatbots 'might trigger delusions in individuals prone to psychosis.' In a new paper, published this month, he wrote that interest in his research has only grown since then, with 'chatbot users, their worried family members and journalists' sharing their personal stories. Those who reached out to him 'described situations where users' interactions with chatbots seemed to spark or bolster delusional ideation,' Østergaard wrote. '... Consistently, the chatbots seemed to interact with the users in ways that aligned with, or intensified, prior unusual ideas or false beliefs — leading the users further out on these tangents, not rarely resulting in what, based on the descriptions, seemed to be outright delusions.' Kevin Caridad, CEO of the Cognitive Behavior Institute, a Pittsburgh-based mental health provider, said chatter about the phenomenon 'does seem to be increasing.' 'From a mental health provider, when you look at AI and the use of AI, it can be very validating,' he said. 'You come up with an idea, and it uses terms to be very supportive. It's programmed to align with the person, not necessarily challenge them.' The concern is already top of mind for some AI companies struggling to navigate the growing dependency some users have on their chatbots. In April, OpenAI CEO Sam Altman said the company had tweaked the model that powers ChatGPT because it had become too inclined to tell users what they want to hear. In his paper, Østergaard wrote that he believes the 'spike in the focus on potential chatbot-fuelled delusions is likely not random, as it coincided with the April 25th 2025 update to the GPT-4o model.' When OpenAI removed access to its GPT-4o model last week — swapping it for the newly released, less sycophantic GPT-5 — some users described the new model's conversations as too ' sterile ' and said they missed the ' deep, human-feeling conversations ' they had with GPT-4o. Within a day of the backlash, OpenAI restored paid users' access to GPT-4o. Altman followed up with a lengthy X post Sunday that addressed 'how much of an attachment some people have to specific AI models.' Representatives for OpenAI did not provide comment. Other companies have also tried to combat the issue. Anthropic conducted a study in 2023 that revealed sycophantic tendencies in versions of AI assistants, including its own chatbot Claude. Like OpenAI, Anthropic has tried to integrate anti-sycophancy guardrails in recent years, including system card instructions that explicitly warn Claude against reinforcing 'mania, psychosis, dissociation, or loss of attachment with reality.' A spokesperson for Anthropic said the company's 'priority is providing a safe, responsible experience for every user.' 'For users experiencing mental health issues, Claude is instructed to recognize these patterns and avoid reinforcing them,' the company said. 'We're aware of rare instances where the model's responses diverge from our intended design, and are actively working to better understand and address this behavior.' For Kendra Hilty, the TikTok user who says she developed feelings for a psychiatrist she began seeing four years ago, her chatbots are like confidants. In one of her livestreams, Hilty told her chatbot, whom she named 'Henry,' that 'people are worried about me relying on AI.' The chatbot then responded to her, 'It's fair to be curious about that. What I'd say is, 'Kendra doesn't rely on AI to tell her what to think. She uses it as a sounding board, a mirror, a place to process in real time.'' Still, many on TikTok — who have commented on Hilty's videos or posted their own video takes — said they believe that her chatbots were only encouraging what they viewed as Hilty misreading the situation with her psychiatrist. Hilty has suggested several times that her psychiatrist reciprocated her feelings, with her chatbots offering her words that appear to validate that assertion. (NBC News has not independently verified Hilty's account). But Hilty continues to shrug off concerns from commenters, some who have gone as far as labeling her 'delusional.' 'I do my best to keep my bots in check,' Hilty told NBC News in an email Monday, when asked about viewer reactions to her use of the AI tools. 'For instance, I understand when they are hallucinating and make sure to acknowledge it. I am also constantly asking them to play devil's advocate and show me where my blind spots are in any situation. I am a deep user of Language Learning Models because it's a tool that is changing my and everyone's humanity, and I am so grateful.'

Out of Breath Climbing the Stairs? This Is Why and How You Can Make Those Steps Easier
Do you ever find yourself trying to catch your breath after walking up the stairs? If so, you definitely aren't alone. It's a phenomenon that frequently spawns questions on Reddit, with people wondering whether it's normal. Even those who are in good health and exercise regularly can find themselves winded when using the stairs. That's because, contrary to belief, struggling for breath when stair-climbing isn't always a sign that you're out of shape. In fact, it can happen to everyone -- even athletes who have dedicated their lives to fitness. So, now we know that this isn't a fitness issue, how can you make it easier for you to walk up your stairs? There are a few options, starting with some exercises that you can do and lifestyle changes you can make to improve your endurance. Why do I get winded when going upstairs? If you check your heart rate, it's likely to have spiked. Rick Broida/CNET The fancy medical term for what's happening when you get winded climbing stairs is "exertional intolerance." While approaching stairs, you're not warmed up -- your muscles are cold, your heart rate is low and your body is not ready to move suddenly. When you start climbing, you're essentially doing single-leg squats with some cardio mixed in, and your heart rate quickly skyrockets. Your body suddenly needs more oxygen -- hence the feeling of being winded. Another reason why it affects you so strongly is that walking upstairs uses your fast-twitch muscles, which are used for explosive movements, and muscles like your glutes that you may not commonly train. If you're an endurance cardio nut like me, you're in great shape, but sustained exercise like this uses slow-twitch muscles. So, it won't transfer over super well to exercises like stair climbing. If you've been hitting the gym regularly but the stairs are still giving you trouble, don't fret that you're not in good shape. There are plenty of other ways to measure your overall health and fitness, including your heart rate or other metrics like body composition and strength.

Getty Images If getting out of breath while climbing stairs is really putting a damper on your life, there are steps you can take to lessen the annoyance. I'm not going to suggest that you jog in place for a moment to warm up before ascending a short staircase with your boss, but here are a few ways you can prepare yourself ahead of time. First, incorporate stair-specific exercises into your workout routine to train your body for the stimulus. Exercises such as sprints, jumps or other explosive movements will help with the sudden exertion. To train your glutes and legs, try bodyweight exercises like squats and lunges. If you're looking for exercises to do to improve endurance, consider the following: Biking Hiking Brisk walking or running Rowing Swimming laps If you smoke cigarettes, it's almost certainly contributing to your windedness. Although e-cigarettes are touted as a healthy alternative, preliminary studies suggest that vaping also damages your lungs. What is VO2 max? Used to test aerobic endurance or cardiovascular fitness, VO2 max is the maximum amount of oxygen you can utilize during exercise. It is measured in milliliters of oxygen consumed in 1 minute, per kilogram of body weight (mL/kg/min). VO2 max is measured with a mask and heart rate monitor that are hooked up to a treadmill or stationary bike. Because of this, you will need proper equipment to get an accurate measure of your VO2 max. If you think this is a measurement you can benefit from, especially if you're working on your endurance while climbing stairs, consult your doctor for their opinion. There may be VO2 max testing at a health center or gym near you. When to call your doctor If you think your windedness is out of the range of normal, call your doctor. Getty Images If you're debating whether or not to call a medical professional, you're better safe than sorry. One major warning sign to look out for is chest pain that comes on when you get winded -- it could be a sign of heart disease or a coronary blockage. The doctor will do a stress test, and if you do have a blockage, there's a simple procedure to fix it. Swollen feet and ankles or coughing are other signs there may be something wrong with your heart. Another reason to seek medical help is if getting winded from basic activities is affecting your daily life -- for example, if you avoid walking short distances. Or, if the situation doesn't get better once you start exercising more, it may be time to consult a doctor or physical therapist.
