If you’ve ever wondered why some people seem to have naturally glowing skin while others struggle with dullness, breakouts, or fine lines, I have great news for you. The secret to glowing skin isn’t just expensive creams or a lucky gene pool; it’s about what you put inside your body just as much as what you put on your skin.

Here at Nava Health, we specialize in longevity and functional medicine and see firsthand how food, supplements, and advanced treatments work together to create youthful, clear skin that radiates health. 

Let’s break it down step by step so you can glow from the inside out. 

Nourish Your Skin with the Right Foods 

Your skin is your body’s largest organ, and just like the rest of you, it thrives on good nutrition. If you want skin rejuvenation, you have to start with what’s on your plate. Here are my top glow-boosting foods: 

  • Fatty Fish (Salmon, Sardines, Mackerel) – Packed with omega-3s, which keep your skin hydrated and reduce inflammation. 
  • Avocados – Loaded with healthy fats and vitamin E to keep skin smooth and supple. 
  • Berries (Blueberries, Strawberries, Raspberries) – Full of antioxidants that protect against skin-damaging free radicals. 
  • Leafy Greens (Spinach, Kale, Swiss Chard) – Rich in vitamins A and C, which promote collagen production and help heal damaged skin. 
  • Nuts & Seeds (Almonds, Walnuts, Chia Seeds, Flaxseeds) – Provide essential fatty acids and antioxidants to fight wrinkles and dryness. 
  • Sweet Potatoes & Carrots – High in beta-carotene, which converts to vitamin A for smooth, even-toned skin. 
  • Dark Chocolate (Yes, Really!) – A source of flavonoids that improve blood flow to the skin, enhancing hydration and radiance. 

Powerful Supplements for Skin Health 

Even the best diet can use a little boost! Here are some key skin-nourishing supplements I recommend for improving skin health: 

  • Collagen Peptides – Help rebuild and maintain skin elasticity. 
  • Vitamin C – Essential for collagen production and brightening skin tone. 
  • Zinc – Fights inflammation and helps with acne-prone skin. 
  • Omega-3 Fatty Acids – Keeps skin hydrated and fights redness. 
  • Hyaluronic Acid – Helps skin retain moisture for a dewy glow. 
  • Probiotics – Support gut health, which directly affects skin clarity. 

Longevity & Functional Medicine Treatments for Youthful Skin 

A healthy diet and smart supplements go a long way, but if you want to take your skin rejuvenation to the next level, functional medicine offers powerful tools to maintain clear, youthful skin. These are my top treatment recommendations: 

1. IV Therapy & IM Booster Shots 

Hydration and nutrient absorption are key to vibrant skin. IV Micronutrient Therapy delivers essential vitamins directly into your bloodstream, helping to replenish skin from the inside out. Some of my favorite skin-boosting IV blends include: 

  • Glutathione – A master antioxidant that brightens skin and fights free radicals. 
  • Vitamin C & B Complex – To support collagen production and reduce fine lines. 
  • Biotin & Amino Acids – For strong, healthy skin, hair, and nails. 

IM (intramuscular) booster shots are also great for a quick skin refresh. A B12 shot, for example, boosts energy while also improving skin clarity and tone. 

2. HydraFacials for Deep Hydration & Glow 

A HydraFacial is like a supercharged facial that deeply cleanses, exfoliates, and hydrates all in one session. It removes dead skin cells, unclogs pores, and infuses your skin with powerful antioxidants and peptides, leaving you with an instant glow. 

3. Exion Fractional & Exion Clear RF for Skin Rejuvenation 

If you want to tighten, smooth, and brighten your skin, Exion’s cutting-edge technology is a game-changer. 

  • Exion Fractional RF stimulates collagen deep within the skin, helping to reduce wrinkles and improve texture. 
  • Exion Clear RF is incredible for acne-prone skin, reducing breakouts and inflammation while promoting skin healing. 

These treatments are completely non-invasive and work beautifully alongside a great diet and supplement routine. 

The Role of Hormones in Skin Health 

Let’s not forget one of the biggest players in skin aging: hormones. As we get older, hormonal shifts (especially around perimenopause and menopause for women or testosterone decline for men) can lead to dryness, fine lines, and loss of elasticity. Bioidentical hormone replacement therapy (BHRT) helps balance estrogen, progesterone, and testosterone levels, which can dramatically improve skin health, hydration, and firmness. 

Your Glow-Up Plan 

Here’s how you can start your journey to clear skin and glowing skin today: 

  • Eat a nutrient-rich diet – Prioritize omega-3s, antioxidants, and collagen-boosting foods. 
  • Supplement smartly – Add collagen peptides, vitamin C, and probiotics to your routine. 
  • Hydrate from within – Consider IV therapy and IM shots for deep skin nourishment. 
  • Treat your skin right – Try HydraFacials and Exion Fractional/Exion Clear RF for next-level rejuvenation. 
  • Balance your hormones – Get tested and explore bioidentical hormone therapy if needed. 

The Takeaway 

You don’t have to lose the luster and glow of your skin as you age! By combining a skin-loving diet with powerful longevity treatments, you can maintain youthful, radiant skin for years to come. Whether you start with small changes or dive into the full functional medicine approach, your skin will thank you.
