Clinical Trial Summary

The purpose of this study is to determine the SPF and UVAPF of four sunscreen formulations using international standard methodologies ISO24444:2010 for SPF and ISO24443:2012 for UVAPF.


Description:

This study consist of two steps. Step 1: determination of the SPF of the test products which will be performed as a single-center, randomized, evaluator blind, intra-individual comparison, no treatment and positive controlled clinical study as per ISO24444:2010. And Step 2: determination of the UVAPF of the test products which will be performed as a single center, open-label, negative and positive controlled technical test as per ISO24443:2012 (using test plates for assessing UV transmittance of four developmental sunscreens).

Outcome

Type Measure Description Time frame Safety issue
Primary Arithmetic Mean of Individual Sun Protection Factor (SPFi) Values Arithmetic mean of all valid SPFi values of each product on each participant was calculated from the individual Minimal Erythemal Dose (MED) on product treated (MEDp) test sites in relation to unprotected (MEDu) test sites 16-24 hours after exposure to ultraviolet (UV) radiation. SPFi = MEDp/MEDu. No inferential statistical analysis was performed for this outcome.The provisional MEDu was the lowest dose of UV radiation that produces the first perceptible unambiguous erythema with defined borders appearing over most of the field of UV exposure.Higher values represents increased SPF protection. Up to 24 hours post UV exposure
Secondary Spectrum of Sun Protection Broad spectrum of sun protection was calculated by the ratio of the arithmetic mean of SPF to the arithmetic mean of UVAPF. Higher values represents increased SPF protection. Up to 30 minutes post UV exposure
