Disrupting Anti-Aging Skincare by Targeting Senescent Cells

Disrupting Anti-Aging Skincare by Targeting Senescent Cells

Imagine accurately determining the status of your skin’s age to tell whether it is younger or older than your chronological age, and then use this technology to determine whether expensive anti-aging serums and creams are effective, or actually causing more harm than good. Amazing, right? This is precisely the technology today’s guest, Dr. Carolina Reis and her fellow stem cell biologists at OneSkin created. I think you will find this interview fascinating on so many levels – I know I sure did! After creating their skin clock, the OneSkin team discovered peptide OS1, which targets senescent cells, one of the root mechanisms of aging, and is being shown in current studies to have a positive effect on hydration, firmness, elasticity, and the skin barrier. Listen as Dr. Reis explains the science and ongoing studies exploring the possible benefits of OS1 for the skin microbiome, hair loss, inflammation, and overall health. ~DrKF

Eggs: Should we eat them, and why is advice still polarized?

Eggs are one of those controversial foods that we were warned against for almost half a century. However, recent years have seen both the American Heart Association and Dietary Guidelines for Americans reverse their restrictions on eggs and dietary cholesterol intake. Rightly so – the evidence didn’t support them, and their redirected emphasis on dietary…

Advances in Curcumin Bioavailability and Improved Absorption for Patients

The therapeutic value of curcumin makes it a fabulous recommendation as both a foundational and medicinal supplement. And since finding a preparation that is bioavailable is key to efficacy, affordability, and patient compliance, I’m excited to have Dr. Sonia Malani (on behalf of Integrative Therapeutics) here to talk about the latest advances in curcumin deliverability and why it matters. Join us as Dr. Malani breaks down the progress of curcumin deliverability and the keys to bioavailability in a way that is simple to understand and easy to pass on to our patients in order to help them move away from the ineffective brands that are currently lining the shelves of local markets so they get the therapeutic influence we are hoping for. I know you’ll enjoy this curcumin talk, and learn a ton from this latest research. Thanks for listening! ~DrKF

Optimize Women’s Exercise According to Hormone Levels, with Dr. Stacy Sims

Today we are taking on a revolutionary and provocative topic that can be quite liberating for women – a deep dive into how to optimize exercise training and performance from the perspective of pre/peri/or post-menopausal. This topic is of great importance to me as a cyclist, and I have to say, there’s a lot of nuance in the way we women should approach training depending on our hormones. My guest Dr. Stacy Sims is a huge talent and tremendous gift — listen as we discuss why women need to train differently than men, including specifics about protein intake, fasting, hormone replacement therapy, and what types of training are best depending on where you are in your cycle. Grab a pen, you’re going to want to take notes! ~DrKF

An Interview with Dr. Fitzgerald on her Latest Research Publication and More

Dr. Fitzgerald’s latest research peer-reviewed publication (published March 2023 in the journal Aging) reports on a case series of women who followed a structured version of her 8-week bioage-targeting protocol. Collectively, the participants reduced their biological age by an average of 4.60 years compared to their baseline. In this month’s blog, we pose some key…

Addressing Long-COVID: Data-Driven Learning Model for Practitioners and Patients

As we find ourselves entering this fourth year since the world was first gripped by COVID-19, on an individual and practice level many of us are still grappling with its post-viral after-effects (long COVID). Drs Patrick Hanaway and Kara Parker, as well as my long-time mentor and former IFM CEO Laurie Hofmann, join me on this podcast to share the important work they have been doing in building practitioner tools and training to address this ongoing challenge (check out the links in the show notes). I just really appreciate their doable, data-driven, and continuous-learning approach, as I’m sure you will too. And if you’re working with COVID-19/long COVID patients (as all of us do, or will, at some point), you’ll want to familiarize yourself with their patient registry so that you too can be part of that essential data collection. – DrKF

Urolithin A: The Game-Changing Nutrient for Healthy Aging

When a team of scientists from EPFL, the Swiss Federal Institute of Technology in Lausanne, set out to thoroughly study the health benefits of pomegranates, they discovered something truly remarkable – the power of a postbiotic nutrient, Urolithin A (UA) to promote cellular health and longevity. For the past 15 years, Urolithin A has been one of the most well-researched longevity molecules. Over 300 studies, 11 of which are clinical trials, show impressive benefits in UA’s ability to target some of the key biological hallmarks of aging. These same scientists and doctors developed the first and only clinically tested Urolithin A formulation (more on that below!)

Skin care. Hands in close-up

How the OS-01 Peptide Works to Reverse Skin’s Biological Age

When we’re young, building a skin care routine is relatively simple: a face wash, moisturizer and sunscreen will do the trick. But as we grow older and develop visible signs of aging skin, choosing from the overwhelming array of mature skin care products like anti-aging creams, serums, and treatments often feels like an impossible task. What can we trust to actually work? It’s easy to get lost in new trends like 10-step skincare routines, but try to look past marketing and prioritize your skin’s health above all else. As our largest organ and first line of defense against environmental aggressors, our skin can have an enormous impact on our overall body health. A truly effective skin care routine should support your skin’s health first and improve the way it looks as a result. That’s where OneSkin comes in.
