Photoallergy
Conditions
Brief summary
The primary objective of this tudy was to evaluate the potential of photoallergy of of sun care products Sun Protection Factor (SPF) 50 Y65 110, SPF 50 Y51 002, and SPF 15 V27 104 application compared to that of a negative control (0.9% sodium chloride, NaCl) and followed by irradiation with UV A and UVB. The secondary objective aims for evaluation of the safety of SPF 50 Y65 110, SPF 50 Y51 002, and SPF 15 V27 104 combined with ultraviolet (UV) A/B irradiation by monitoring adverse events (AEs) throughout the study.
Interventions
Application of 200 µL in an occlusive patch of Webril (0.150 ± 0.010 mg) compared to that of a negative control (0.9% sodium chloride, NaCl) and followed by irradiation with UV A and UVB.
Application of 200 µL in an occlusive patch of Webril compared to that of a negative control (0.9% sodium chloride, NaCl) and followed by irradiation with UV A and UVB.
Application of 200 µL in an occlusive patch of Webril compared to that of a negative control (0.9% sodium chloride, NaCl) and followed by irradiation with UV A and UVB.
Negative control (200 µL, 0.9% sodium chloride \[NaCl\]) after a single 24 h application of test materials followed by irradiation with ultraviolet A (UVA) and ultraviolet B (UVB).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of inflammatory responses | up to 3 weeks | Inflammatory responses (Based on scores): 0 = No visible reaction + = Slight, confluent, or patchy erythema 1 = Mild erythema (pink) 2 = Moderate erythema (definite redness) 3 = Strong erythema (very intense redness) |
| Evaluation of superficial effects | up to 3 weeks | Superficial effects: g = Glazing y = Peeling c = Scab, dried film of serous exudate of vesicular or bulla reaction d = Hyperpigmentation (reddish brown discoloration of test site) h = Hypopigmentation (loss of visible pigmentation at test site) f = Fissuring grooves in the superficial layers of the skin |
Secondary
