"The results of this case study underscore that we must nourish the dermis at a molecular level. The combination of high-dose Hyaluronic Acid, Vitamin C and NAD+ precursors provides a necessary foundation for any patient striving for structural skin improvement and accelerated recovery."

Dr. Olivier Beckers, Facial Surgeon

Subject & Method

The user has dealt with sensitive, reactive, and easily reddened skin since infancy. Despite a lifestyle centered on optimal training, nutrition, and recovery, his skin remained a point of vulnerability, often reacting to stress, physical exertion, and environmental changes.

The patient integrated SKIN FUEL™ into his daily routine for a period of three months. To objectively measure the results, clinical skin analyses were performed using the Observ 520x technology at Instituut Merel. We compared the baseline (T0: Nov 8, 2025) with the progress after six weeks of consistent use (T1: Dec 21, 2025).

1. Vascular Calming (Redness Analysis)

The Technology: Cross-Polarized (CP) lighting filters out surface reflections to reveal vascular activity and inflammation beneath the surface.

  • Observation: The baseline scan showed significant diffuse redness and vascular unrest on the nose and cheeks.
  • The Transformation: After 6 weeks, there is a visible reduction in red zones, and the user reported the skin became significantly "calmer".
  • Impact: The skin is less reactive to external triggers such as intense exercise and temperature shifts.

2. Structural Integrity (Texture & Surface)

The Technology: Texture mode highlights the skin's micro-relief, including fine lines and surface uniformity.

  • Observation: Initial scans showed a "fragile" skin texture with visible fine lines.
  • The Transformation: The follow-up scan reveals a smoother surface where fine lines have become visibly softer and more even.
  • Impact: The patient reported that the skin feels more "resilient" and robust rather than thin or easily irritated.

3. Deep Hydration & Barrier Health (UV Analysis)

The Technology: True UV and Wood’s light detect deep-seated skin conditions, including dehydration and lipid balance.

  • Observation: Baseline scans showed uneven hydration levels and deeper vulnerabilities in the skin barrier.
  • The Transformation: The follow-up scan shows a healthier, more balanced reflection, indicating the skin is better hydrated and nourished from within.
  • Impact: This proves the improvement is not merely cosmetic but rooted in the deeper layers, providing a gradual and lasting improvement.

Expert Medical Report: Evaluation of Cellular Skin Improvement

By: Dr. Olivier Beckers – Facial Surgeon


As a facial surgeon, I view the skin not just as an aesthetic surface, but as a complex biological system where structural integrity and vascular stability are essential. The results observed in this patient after six weeks of using SKIN FUEL™ are, from a medical standpoint, highly consistent with improved cellular homeostasis.

The Essential Role of NAD+ in Skin Rejuvenation

The presence of Nicotinamide Riboside (NR) as a NAD+ precursor in SKIN FUEL™. NAD+ is a co-enzyme found in every living cell, crucial for what we call "cellular refueling" and essential for energy production (ATP) and DNA repair.

As we age, or through exposure to UV radiation and stress, our natural NAD+ levels decline significantly. In the skin, this leads to slower cell renewal and decreased collagen production. By replenishing NAD+ levels from within, SKIN FUEL™ supports the skin's natural repair mechanisms. This explains why the patient saw improvements in skin texture and experienced increased mental clarity; the energy supply of the cells was optimized across the entire body.

The Role of ABSORPTIX® Technology

The distinguishing factor in this case is bioavailability. Many supplements fail because large molecules, such as Hyaluronic Acid, cannot bypass metabolic barriers. The patented ABSORPTIX® technology eliminates these barriers, ensuring that the bio-active ingredients actually reach the deeper dermal layers to effect structural change.
