SPF with Water Resistance

The In Vivo SPF Panel with Water Resistance involves assessing the effectiveness of sunscreen products in protecting the skin from harmful UV radiation and preventing sunburn, even when exposed to water or sweat.

Procedure:

1. Sample Selection: Obtain sunscreen samples from various manufacturers, including creams, lotions, sprays, and sticks, with different SPF levels and water resistance claims.

2. Testing Protocol:

   • Conduct in vivo tests on human subjects to determine the Sun Protection Factor (SPF) of each sunscreen product, considering its water resistance claims.
   • Expose the skin of the participants to controlled amounts of UV radiation in a laboratory setting, simulating real-world conditions.
   • Measure the time it takes for the skin to develop redness or sunburn when exposed to UV radiation with and without sunscreen application, even after immersion in water or exposure to sweat.
   • Calculate the SPF value based on the ratio of the UV dose required to cause sunburn with and without sunscreen, considering water resistance properties.

3. Data Analysis: Analyze the results to determine the SPF value of each sunscreen product under water resistance conditions and assess its efficacy in protecting against UV radiation, even in wet conditions.

4. Education and Recommendations: Provide information to participants about the importance of using water-resistant sunscreen, especially during outdoor activities involving water or sweating.

5. Recommendations for Use: Educate consumers about the significance of water resistance in sunscreen products and emphasize the importance of reapplying sunscreen regularly, especially after swimming or sweating.

Claims:

• Provides effective protection against harmful UV radiation, reducing the risk of sunburn and skin damage, even when exposed to water or sweat.
• Water-resistant formula ensures prolonged protection during water activities or sweating, maintaining SPF efficacy.
• SPF values indicate the level of protection against UVB rays, with higher SPF offering greater protection, even in wet conditions.
• Suitable for outdoor enthusiasts, athletes, and individuals engaging in water activities, offering reliable sun protection.
