Face mists are everywhere right now. But most of them are just water and fragrance in a fancy bottle. Today on Daily Dose a scientist breaks down what's actually happening when you spritz something on your skin, what ingredients make a face mist genuinely functional, and why bioavailability is the question the skincare industry hopes you never ask.Plus, the American Academy of Neurology just told patients to start bringing their smartwatch data to doctor's appointments, and we get into the actual science of venting. Turns out complaining can be good for you, BUT only if you're doing it right. Bottling things up is just as bad as the science says it is.Simple science, real news, no hype.

A study of 72,000 people just confirmed what deep down we all know: walking more saves lives. Up to 39% lower risk of dying, regardless of how much time you spend sitting.Today’s on Daily Dose we break that down and talk about why the simplest habits keep winning in the science. We also get into why the type of olive oil in your kitchen is actively changing your brain health through your gut — and why the refining process strips out the exact compounds that make it work.And we look at new research showing that the timing of your exercise, matched to your natural body clock, can meaningfully improve blood pressure, sleep, and metabolic health.Three stories, all pointing to the same truth: your biology rewards you for working with it, not against it.Simple science, real news, no hype.

The food industry has spent decades perfecting the art of making unhealthy food look healthy. One buzzword on the front of a packet: organic, plant-based, gluten-free — and your brain automatically assumes the whole product is good for you.Scientists call it the Health Halo Effect, and it's one of the most powerful marketing tools ever invented. Today on Daily Dose I break down exactly how it works, the specific words to watch out for, and how to read a food label the way a scientist does. Plus a major new study on loneliness and memory that has a surprising twist, and the collagen conversation the supplement industry doesn't want you having, because it turns out collagen alone isn't enough, and the science now shows exactly why.Simple science, real news, no hype.

Losing your sense of smell might sound like a minor inconvenience. Turns out it could be one of the earliest warning signs of Alzheimer's, years before any memory problems show up. Scientists this week found that the brain starts destroying smell-related nerve fibres long before symptoms appear, which changes how we think about early detection entirely.Today, on Daily Dose I break down what that means and what to watch for, plus the science finally has an exact answer on how many serves of fruit and vegetables you actually need each day and most of us are eating half that amount. And we take a look at the Silicon Valley longevity machine and why the tech billionaires spending millions to live forever might be missing what the science has been saying all along.

Red light therapy is having a moment. Face masks, panels, helmets, wands — you can spend $50 or $5000, and TikTok will tell you it fixes everything from wrinkles to period cramps to longevity.But here's the thing, the underlying biology is actually real. It works at the mitochondrial level, it has genuine clinical evidence in specific areas, and some of the results are genuinely interesting. The problem is the gap between what the science shows in a lab and what a home device actually delivers is enormous.Today, on Daily Dose I cut through the noise on red light therapy and tell you exactly where it works and where it doesn't. Plus, a new study found that seven days of meditation produces the same brain patterns as psychedelics, and a Weizmann Institute study that flips everything we thought we knew about genes and how long we live.Simple science, real news, no hype.

Your brain has its own cleaning system — and most of us are unknowingly shutting it down every night. Scientists have just discovered a hidden waste-removal pathway deep inside the brain, a slow lymphatic-like drain that flushes out toxic buildup while you sleep. When it stops working, that waste accumulates, and researchers believe this is directly linked to the development of Alzheimer's and other neurodegenerative diseases.In today’s Daily Dose, I break down what this discovery actually means, why sleep is the single most underrated tool in your brain health arsenal, and how chronic inflammation could be quietly clogging your brain's drain before symptoms ever appear. Plus — the two eating habits a major new study says are linked to lower weight with no dieting, and why your gut bacteria might just replace the colonoscopy forever.

Before you get too excited about vodka, I want to share something quite personal first. I used to think I had my health figured out. 10,000 steps a day, decent nutrition, a science background to back it all up.But what I didn’t realise was that knowing isn’t the same as doing, and doing isn’t the same as doing it consistently. So, I thought let me include this Long Story Short episode in this newsletter, where I shared what almost stopped me from starting, why I was wrong about structured training, and how a simple decision to “just give it a go” ended up changing not just my fitness, but my energy, mindset, and daily performance.To be clear, this isn’t about chasing perfection or looking a certain way. It’s about unlocking a version of yourself you didn’t even know you were missing. From training like an athlete to finding unexpected community in a room full of strangers, this episode is a reminder that health isn’t built in one moment, it’s built in the moments you show up. If you’ve been waiting for the right time to start, this might be it.Let me know what you think!With my best,Dr Vincent Get full access to Ask Dr Vincent at www.askdrvincent.com/subscribe

I have joined The Nappy Collective as their official Advocate to lead the fight to eliminate the Nappy Crisis in Australia. This Anti-Poverty Week, which runs from October 12 to 18, The Nappy Collective is aiming to raise $10,000 to continue their work supporting families in crisis.On this special episode of The Core Conversation, Sue Karzis, the CEO of The Nappy Collective, joined me to talk about the amazing work her organisation is doing to help families in Australia. Nappies are not luxury items and most of us are not even thinking that there is an affordability issue around nappies. Unfortunately it is an everyday struggle for thousands of families, many of them are single mothers fleeing domestic violence and often are unhoused. Newborns go through up to 12 nappies daily and the cost can equate to about 9 per cent of a single parent’s income when they are living under the poverty line. One in six Australian kids live in poverty.The Nappy Collective is the only initiative in Australia that directly addresses this issue, and Karzis said that visiting one of the organisation’s 800 charity partners is often “the only thing” available to parents who cannot afford clean nappies.The Nappy Collective works to redistribute their supplies to those in-need areas, but without the funding for transport, it constantly relies on other charities and volunteers to help deliver nappies to struggling parents across the country.For those looking to donate nappies, collection boxes can be found in 850 locations including Baby Bunting stores, childcare centres and even the offices of some MPs.Cash donations also help The Nappy Collective to purchase certain sizes of nappies that are not being donated, which people are desperate for.Parents in need of nappies are urged to check with their local community centre, child health nurse, or support worker, and ask to be connected with The Nappy Collective and support available in their area.Read the 7News coverage on this crisis.

Recently I have been inundated by questions about our gut health and skin health, especially acne. The two main questions are around "Your skin is your biggest detox organ," or "Bad bugs from your gut get pushed out through the skin and cause acne." I am so happy that people are curious and I am so proud that you question things that you watched, heard or read on social media when they sound not quite right.So, let’s break it down.The Gut-Skin Connection: What Science Says1. Gut Inflammation = Systemic InflammationWhen your gut is inflamed, be it from processed foods, chronic stress, infections, or an overgrowth of harmful bacteria (the so-called “bad bugs”), it can trigger a domino effect that leads to a condition called systemic inflammation.Essentially, your whole body becomes inflammed and put you in a fight or flight mode. This often shows up on your skin as acne, eczema, or rosacea.2. Microbiome Imbalance Fuels AcneAn imbalanced gut microbiome (dysbiosis) disrupts:* Sebum production* Hormonal regulation* Immune responsesAll of which contribute to acne flare-ups. The gut and skin communicate constantly via what we call the gut-skin axis.3. Immune System CrosstalkIf you are a frequent reader or listener of Ask Dr Vincent, you know that over 70% of your immune system lives in the gut. When your microbiome is out of balance, your immune system becomes reactive.That can mean more inflammation, more flare-ups, and more breakouts BUT not because the bugs are "escaping" but because your whole body is on edge.So why do you need to look after your gut to care for your skin?Let’s be clear. “Bad gut bugs” don’t literally crawl or leak out through your skin. That’s not how the body works.* Acne isn’t caused by microbes physically exiting the gut.* Gut bacteria do not get excreted through your pores.* There’s no direct detox route from gut to skin.Your gut talks to your skin through:* Immune signalling* Hormonal pathways* Metabolic byproducts (like toxins and short-chain fatty acids)So when your gut is inflamed or imbalanced, your skin listens and reacts.That’s why improving gut health with an anti-inflammatory diet, fibre, probiotics, and plenty of hydration often leads to clearer, healthier skin.And, while your skin is your largest organ by surface area, but when it comes to detoxification, our liver and kidneys are the ones doing the heavy liftingOur liver filters blood, neutralises toxins, breaks down alcohol and medication, and transforms harmful compounds into water-soluble forms so they can be safely excreted.Our kidneys remove waste products through urine, handling the byproducts of digestion, cellular activity, and toxins filtered by the liver.Our skin can excrete a tiny amount of waste like urea, ammonia, and salts through sweat, but it’s minimal and not a major detox pathway. Sweating won’t remove bacteria, heavy metals, drugs, or other large toxins in any meaningful way.Don’t get me wrong, your skin is important, but it’s not doing the deep clean. That’s your liver and kidneys' job.TDLRGut inflammation and microbiome imbalances absolutely affect your skin, but not by “pushing bugs out.”Your liver and kidneys are the real detox powerhouses.Your skin reflects your internal state — it's not your rubbish chute.Take care of your gut, support your detox organs, and your skin will thank you.Thank you to everyone who tuned into my live video!
