1. Introduction

In this enlightening episode of Skincare Anarchy, host Ekta welcomes Simon Sakhai, the visionary founder of Young Longevity. The discussion delves deep into the intricate science of skin longevity, challenging conventional skincare norms and exploring cutting-edge longevity science.

2. Simon Sakhai’s Journey into Longevity Science

Simon begins by sharing his unconventional path to longevity science:

• Initial Focus on Sleep Medicine:
  “I didn't start out in longevity. I was working in sleep... developing a sleep diagnostic program.” [00:38]

• Transition to Longevity:
  Invited to a longevity seminar at Oxford, Simon was initially skeptical but became fascinated by the potential to “actually solve aging” after understanding the scientific frameworks presented. His growing obsession led him to pivot his startup from sleep diagnostics to longevity and eventually take leadership roles in the Oxford Society of Aging and Longevity. [01:03]

3. Understanding Longevity Science

Simon elucidates the foundational principles of longevity science:

• Systemic Approach to Health:
  “We can't look at our body in silos...” emphasizing the interconnectedness of various health aspects like sleep, diet, and skin health. [05:27]

• Hallmarks of Aging:
  initially nine, now expanded to twelve, these are fundamental mechanisms driving the aging process. Simon explains that addressing these hallmarks can potentially “make you live forever,” highlighting the ambitious yet scientifically grounded goals of the field. [05:27]

4. The Twelve Hallmarks of Aging

Simon details several key hallmarks relevant to skin health:

• Chronic Inflammation:
  Recently added to the hallmarks, chronic inflammation accelerates aging by promoting senescent cell buildup. [05:27]

• Senescent Cells (“Zombie Cells”):
  Cells that refuse to die, secreting enzymes that exacerbate aging and inflammation. Simon notes, “Your skin is the largest site of senescent cell production.” [12:29]

• NAD Decline:
  Declining levels of NAD impair cellular energy production, crucial for skin health and overall longevity. [05:27]

5. Senescent Cells and Skin Aging

A significant portion of the conversation focuses on the detrimental role of senescent cells:

• Impact on Skin and Systemic Health:
  Senescent cells in the skin not only cause visible signs like wrinkles but also release toxins that accelerate aging in other organs. Simon emphasizes the need for systemic solutions rather than localized topical applications.
  “Senescent cells don't just stay where they're born... they go into other parts of your body, and they accelerate aging there.” [16:45]

• Critique of Topical Solutions:
  Addressing only the skin’s surface fails to mitigate the systemic effects of senescent cells, advocating for internal approaches to managing these cells. [16:53]

6. Critique of Topical Skincare Products

Simon provides a scientific critique of popular skincare practices:

• Molecular Size Barrier:
  Topical products often fail to penetrate the skin due to molecular size limitations.
  “The 500 Dalton rule... most compounds like collagen (120,000 Daltons) and hyaluronic acid (10-15,000 Daltons) cannot pass through.” [20:18]

• Ineffectiveness of Moisturizers for Aging:
  While moisturizing is beneficial, it doesn't address the core drivers of aging. Simon calls it “fake news” that moisturizers can significantly slow the aging process. [20:18]

7. The Role of Systemic Supplements

Transitioning from topicals, Simon advocates for a systemic supplement approach:

• Cellular Skin Renewal Formula:
  Young Longevity’s flagship supplement targets all twelve hallmarks of aging with evidence-based ingredients.
  “Avoid silver bullet solutions... think portfolio approach.” [23:49]

• Key Ingredients and Their Functions:

  • Niacinamide: Increases NAD levels, supporting cellular energy.
  • Spermidine: Clears senescent cells by stimulating autophagy.
  • Vitamin C and E: Protect fibroblasts from oxidative stress.
  • Collagen Peptides (Verocel): Stimulate the body’s collagen production rather than replacing it directly. [22:36 – 32:53]

8. Understanding NAD and Its Importance

A deep dive into NAD reveals its critical role in aging:

• NAD vs. Precursors (NMN, NR):
  Direct NAD supplementation is ineffective due to its instability and poor cellular uptake. Instead, precursors like NMN and NR are essential for boosting intracellular NAD levels.
  “Just supplementing for NAD doesn't really work... you need precursors.” [48:40]

• Issues with NAD IV Drips:
  Simon highlights the instability of NAD in IV drips and questions their efficacy in increasing intracellular NAD levels.
  “I’m not an expert on NAD stability, but I see a lot of hype...” [48:40]

9. Debunking Sunscreen Myths

Simon challenges the pervasive use of sunscreens:

• Over-reliance and Side Effects:
  Excessive sunscreen use can hinder vitamin D production and disrupt circadian rhythms.
  “Skincare industry is telling people to walk around every day, put on tons of stuff... it's blocking UV that helps our bodies create vitamin D.” [34:59]

• Astaxanthin as an Alternative:
  Introducing astaxanthin, a carotenoid that provides systemic protection against UV damage without the drawbacks of topical sunscreens.
  “Astaxanthin is like sunblock in a supplement...” [36:30]

10. Lifestyle Factors Affecting Skin Health

Simon emphasizes the importance of lifestyle in skin longevity:

• Dietary Sugar Reduction:
  High sugar intake leads to the formation of advanced glycation end products (AGEs), which degrade elastin and promote wrinkles.
  “Cut sugar. Try a low carb diet. Our Glucose Blocker helps mitigate the effects of high blood sugar.” [54:43]

• Quality Sleep:
  Sleep is crucial for cellular repair and regeneration. Simon outlines supplements that support high-quality sleep, enhancing skin health.
  “Sleep is nature’s longevity miracle... is part of our longevity strategy.” [54:43]

• Intermittent Fasting and Caloric Restriction:
  These practices stimulate autophagy, aiding in the clearance of damaged cells and proteins.
  “Fasting stimulates autophagy, which helps renew and clear out dead cells...” [70:58]

11. Inflammation and the Microbiome

Exploring the roles of inflammation and the microbiome:

• Chronic Inflammation:
  While a natural part of the immune response, chronic inflammation can exacerbate aging. However, Simon notes it's often overhyped in supplement marketing.
  “If you're living a healthy lifestyle, you shouldn't worry too much about it.” [65:03]

• Skin Microbiome:
  The skin's microbiome is delicate and can be disrupted by excessive topical product use, leading to increased inflammation.
  “Messing with the microbiome can cause more problems... we're better off using prebiotics to support existing beneficial bacteria.” [66:23]

12. Practical Advice for Consumers

Simon offers actionable steps for listeners seeking to enhance their skin health:

1. Adopt a Portfolio Approach:
   Address multiple hallmarks of aging simultaneously rather than relying on single solutions.
   “Avoid silver bullet solutions... think portfolio approach.” [71:05]

2. Minimize Topical Use:
   Focus on systemic solutions rather than extensive use of topical products that offer limited penetration and benefits.
   “Cut the topicals... our products are designed to work systemically.” [71:05]

3. Focus on Lifestyle Changes:
   Implement dietary adjustments, optimize sleep, and consider intermittent fasting to support overall and skin-specific longevity.
   “Look at your lifestyle... what are you eating? Are you eating lots of sugars?” [71:05]

• Commitment and Consistency:
  Longevity and skin health require long-term dedication to lifestyle and supplement regimens.
  “You have to stick to it. It’s a long-term strategy.” [76:33]

13. Young Longevity’s Approach and Offerings

Simon details Young Longevity’s holistic and evidence-based approach:

  Targeting all twelve hallmarks of aging with morning and night-specific supplements.
  “We have a master formula that targets all twelve drivers of aging.” [77:46]
