The Science
THE METHODOLOGY
The UV Age Clock™ is a proprietary data model built on published photobiological research. Here is the science behind every number.
86%
The Photoaging Foundation
Published dermatological research consistently demonstrates that approximately 80–86% of visible skin aging is attributable to UV-induced photoaging. The mechanisms - reactive oxygen species generation, matrix metalloproteinase activation, collagen degradation, and DNA strand breaks - are dose-dependent and directly correlate with UV index and exposure duration. This is the scientific foundation of the UV Age Clock™ model.
∫
The Damage Curve
The model applies a base rate of 0.08 aging-days per UV-index-minute, with an exponential multiplier at higher UV categories reflecting the non-linear free radical cascade that occurs above threshold UV levels. Low UV: linear (×1.0). Moderate: ×1.08. High: ×1.20. Very High: ×1.32. Extreme: ×1.48. This reflects published research showing disproportionate cellular damage at higher UV intensities.
93%
SPF 30 Protection Factor
SOL LABS SPF 30 with non-nano zinc oxide provides 96.7% UVB blockage and approximately 88–90% reduction in UVA penetration. The blended photoaging protection factor - accounting for the relative contribution of UVA and UVB to cumulative photoaging - yields a net reduction of approximately 93% in aging day accumulation versus unprotected exposure.
