| Blue Light Protection | Yes | Confirmed defense against high-energy visible light (400-500 nm) |
3.2 Clinical Interpretation of Results
| Metric | Interpretation |
|---|---|
| SPF 57.689 (In-Vivo) | Under standardized laboratory conditions per ISO 24444:2019, the product demonstrated approximately 58 times more protection against UVB-induced erythema compared to unprotected skin. This result classifies the product as SPF 50+, the highest tier on the international SPF scale (Diffey, 2001, PMID: 11348430). |
| SPF 70.96 (In-Vitro) | The in-vitro result of 70.96, measured using the COLIPA guideline optical method, exceeds the in-vivo result of 57.689. This indicates strong UV filter performance in controlled laboratory conditions with real-world performance confirming reliable protection (COLIPA, 2011). |
| PA++++ | PA++++ is the highest category in the Protection Grade of UVA rating system used across India, Japan, South Korea, and Southeast Asia. It requires a UVA Protection Factor of 16 or above, signifying very high defense against UVA rays responsible for photoaging and deep skin damage (Wang et al., 2011, PMID: 21463374). |
| Critical Wavelength 380 nm | Critical wavelength measures the point where 90% of a sunscreen's total UV absorbance occurs. At 380 nm, this product exceeds the international 370 nm threshold by 10 nanometers, confirming extended coverage into the UVA-I range (340-400 nm) responsible for deep dermal penetration (Wang et al., 2011, PMID: 21463374). |
| Broad Spectrum | Broad spectrum certification means the product's UV protection extends meaningfully across both UVB and UVA wavelengths. UVB causes sunburn while UVA drives photoaging and deeper structural damage. A critical wavelength of at least 370 nm is required for broad spectrum classification (Wang et al., 2011, PMID: 21463374). |
| Blue Light Protection | Blue light (high-energy visible light, 400-500 nm) can induce oxidative stress, hyperpigmentation, and premature aging. The confirmed blue light protection indicates the formulation contains antioxidants that help neutralize free radicals generated by high-energy visible light (Liebel et al., 2012, PMID: 22436096). |
