| Résumé : |
There was no significant difference between erythemal responses when measured according to ISO 24444 Procedure.
Similarly, there was no significant difference between erythemal responses measured instrumentally.
Moderation of erythemal response by the SPF 100 sunscreen containing high level (39%) of actives was not observed.
Evidence of anti-inflammatory activity of sunscreen actives was nto apparent when a commercial very high SPF product was tested under standard internationally-accepted test conditions intended to reflect normal use.
When a mainstream therapeutic anti-inflammatory active was incorporated into a standard SPF 15 sunscreen, there was an a value change of 0.48 at 1x MED exposure, increasing to 1.1 at 2x MEDs. The impact of this effect on SPF 16 protected skin was at best incremental, and extrapolation from the percentage decrease in erythema could only, at best, be additive.
The changes could not be observed visually when assessed according to the ISO 24444 SPF protocol, but could only be shown with instrumental measurement with a colour computing spectrophotometer. Significant difference could not be confirmed for any of the test series for treated vs. untreated challenges. |
