---|---|
Experimental: SPF Testing
Following Food and Drug Administration (FDA) guidelines for SPF testing, exposure control and product-protected site erythema responses are scored after 16 to 24 hours post-exposure to full spectrum light (Ultraviolet B radiation [UVB] and UVA).

Sunscreen formula containing 15% Zinc Oxide, 3% Avobenzone, and 1% Ensulizole
Sunscreen formula containing 15% Zinc Oxide and 3% Avobenzone
8% Homosalate Standard SPF 4 Sunscreen

Experimental: UVA Protection Testing
Determination of Ultraviolet A Protection Factor (PFA).
Following FDA guidelines, test sites exposed to UVA are scored for pigmentation responses 2 to 4 hours post-exposure.

---|---|---|
Determination of Sunscreen Protection Factor (SPF)
Time Frame: 16 to 24 hours post-exposure
|
Test material (V53-028 and V53-030) and control test material (8% Homoslate SPF 4) were applied to test area.
Following exposure to a series of Ultraviolet light exposures, SPF scores were recorded at 16 to 24 hours post-exposure, to determine the Minimal Erythema Dose (MED) of protected and unprotected skin.
SPF was calculated as the MED of protected skin divided by the MED of unprotected skin.
Expected SPF 15 is a score on a scale; range 11.34 (worst) to 19.83 (best).
|
16 to 24 hours post-exposure
|
Determination of Ultraviolet A Protection Factor (PFA)
Time Frame: 2 to 4 hours post-exposure
|
Test materials (V53-028 and V53-030) were applied to test area.
Following a series of Ultraviolet radiation A (UVA) exposures, scores were recorded at 2 and 4 hours post-exposure, to determine the Minimal Persistent Pigment-Darkening Dose (MPPD) of protected and unprotected skin.
PFA was calculated as the MPPD of protected skin divided by the MPPD of unprotected skin.
Expected PFA is a score on a scale; range 6.40 (worst) to 15.62 (best).
