  • Summary

  • In this episode, we explore the fascinating world of sunscreen ingredients and how they work to protect our skin from harmful UV rays. Sunscreens contain active ingredients that either reflect or absorb UV radiation, as well as emollients to keep the skin soft and stable. Mineral filters like zinc oxide and titanium dioxide sit on the skin's surface and reflect UV radiation, making them ideal for sensitive skin. Chemical filters like avobenzone and octocrylene absorb UV radiation and convert it into heat, providing broad-spectrum protection. When choosing a sunscreen, it's crucial to look for broad-spectrum and water-resistant protection, along with an SPF of at least 30. Consider your skin type and preferences when selecting a sunscreen formula, whether it's a gel for oily skin or a mineral-based option for sensitive skin. Proper application and reapplication are key for effective sun protection, along with other preventive measures like wearing hats and sunglasses. Sunscreen is just one part of a comprehensive sun safety strategy, so remember to practice other protective measures and consult with a healthcare provider for personalized advice.
