  2. Understanding UV Radiation UVA Rays Penetrate deeply into skin, causing premature aging, wrinkles, and long-term damage. Present year-round, even through clouds and windows. UVB Rays Target the skin's surface, causing sunburns and playing a key role in skin cancer development. Intensity varies by season and time of day. Both UVA and UVB rays contribute to skin cancer risk and damage. Broad-spectrum sun protection guards against both types effectively. InstagramFacebookYoutubeX Pinterest

  3. Types of Sunscreen Physical (Mineral) Chemical (Organic) • Contains zinc oxide or titanium dioxide • Absorbs into skin layers • Sits on skin surface, reflecting UV rays • Converts UV rays to heat energy • Works immediately upon application • Requires 15-20 minutes to activate • Ideal for sensitive skin types • Lighter, more cosmetically elegant Choose broad-spectrum formulas with SPF 30 or higher for optimal protection. Reapply every two hours and after swimming or sweating. InstagramFacebookYoutubeX Pinterest

  4. Common Sun Exposure Myths Myth: You don't need sunscreen on cloudy days Myth: Darker skin doesn't need sun protection Truth: Up to 80% of UV rays penetrate clouds. Daily sun protection is essential regardless of weather conditions. Truth: While melanin provides some natural protection, all skin types are vulnerable to UV damage and need sunscreen. Myth: A base tan protects against sunburn Myth: Sunscreen prevents vitamin D absorption Truth: Tanning is your skin's injury response. It offers minimal protection (SPF 3 or less) and indicates DNA damage. Truth: Sunscreen allows sufficient UV for vitamin D production. You can also obtain vitamin D through diet and supplements safely.

  5. Your Sun Protection Action Plan 01 02 03 Apply Generously Reapply Frequently Seek Shade Use one ounce (shot glass full) of sunscreen for full body coverage, 15-30 minutes before sun exposure. Reapply every two hours, or immediately after swimming, sweating, or towel drying. Limit direct sun exposure between 10 AM and 4 PM when UV rays are strongest. 04 05 Wear Protection Check Expiration Complement sunscreen with protective clothing, wide-brimmed hats, and UV-blocking sunglasses. Replace sunscreen after three years or if exposed to high temperatures, which can reduce effectiveness. Make sun protection a daily habit for lifelong skin health. Your skin will thank you for decades to come! InstagramFacebookYoutubeX Pinterest
