On Today's Five Minute Friday, listen to why it's key to think of how well you support your immune as part of your beauty plan! A weak immune system works against your treatments- causing more swelling, slower recovery, and less collagen response. A strong immune system works with your treatments meaning it will amplify results, shorten downtime, and keep your skin vibrant and youthful. Your immune system is your best beauty ally so let’s make sure it’s ready to help you glow this season and beyond.

Summer heat takes a toll on your skin. In this week’s podcast, we’re talking dryness, irritation, and the breakdown of your lipid barrier. This natural barrier is your shield against environmental stressors, and when it’s disrupted, inflammation follows. As the season shifts, it’s the perfect time to repair and restore. We’ll cover why ceramide-rich moisturizers matter, how hydrating soaks help replenish, and why it’s smart to ease up on exfoliation. Plus, we share tips on diet, recovery treatments, and why end-of-summer peels set you up for glowing, resilient skin heading into fall.

When it comes to protecting your body from aging and stress, glutathione deserves the spotlight; in today's Five Minute Friday- we breakdown exactly why we love glutathione! This antioxidant is produced naturally from amino acids and acts as your internal shield against free radicals and toxins. It doesn’t just fight oxidative stress—it also helps recycle other antioxidants, keeping your defense system running smoothly. Levels of glutathione drop with age, stress, and illness, which is why it’s smart to support production every day. You can do this with simple changes: load up on cruciferous vegetables, add garlic and onions to your meals, get enough vitamin C and selenium, and try whey protein for its cysteine content. Even herbs like milk thistle play a role in keeping glutathione levels steady. Think of it as strengthening your body’s reset button. When glutathione is optimized, your energy improves, your skin looks healthier, and your cells are better protected against damage. Making these small, consistent choices helps your body stay resilient, youthful, and strong.

Peeling skin, redness, and pain - are you experiencing these symptoms after your relaxing summer vacay? You probably have sunburn! Sunburns develop as a result of being exposed to the ultraviolet (UV) rays emitted by the sun or artificial UV light sources. It's important to note that sunburns can contribute to premature aging of the skin and increase the risk of developing skin cancer. Taking proactive measures to protect your skin can help reduce the chances of getting sunburnt. Aloe Vera, for instance, is a great way to alleviate a sunburn.
