Crèmes solaires - 10 things to know with detail
- 1. Sun Protection Factor (SPF): SPF measures the level of protection a sunscreen offers against UVB rays, which are responsible for sunburn. The higher the SPF, the greater the protection. It is recommended to use a sunscreen with at least SPF 30 for optimal protection.
- 2. Broad Spectrum Protection: Look for a sunscreen that offers broad spectrum protection, which means it protects against both UVA and UVB rays. UVA rays can penetrate deeper into the skin and are responsible for skin aging and long-term damage.
- 3. Water Resistance: If you will be swimming or sweating, choose a water-resistant sunscreen to ensure it stays effective for a longer period of time. Remember to reapply after swimming or sweating, as water resistance does not mean the sunscreen is waterproof.
- 4. Application: It is important to apply sunscreen generously and evenly to all exposed skin at least 15 minutes before going outside. Be sure to reapply every two hours, or more frequently if swimming or sweating.
- 5. Skin Type: Consider your skin type when choosing a sunscreen. If you have sensitive skin, look for a sunscreen that is hypoallergenic and fragrance-free. For oily skin, opt for a lightweight, non-comedogenic formula.
- 6. Active Ingredients: Sunscreens contain active ingredients that help protect the skin from UV damage. Common active ingredients include zinc oxide, titanium dioxide, avobenzone, and octinoxate. Be sure to check the label for these ingredients when selecting a sunscreen.
- 7. Expiration Date: Sunscreen can lose its effectiveness over time, so be sure to check the expiration date before using. Expired sunscreen may not provide adequate protection against UV rays.
- 8. Sunscreen for Kids: Children have more sensitive skin than adults, so it is important to choose a sunscreen specifically formulated for kids. Look for a gentle, pediatrician-recommended formula with a high SPF.
- 9. Sunscreen and Makeup: If you wear makeup, consider using a sunscreen that can be worn under or over your makeup. Some sunscreens are specifically designed to be worn with makeup and won't interfere with its application.
- 10. Sunscreen All Year Round: Sunscreen should be worn year-round, not just in the summer months. UV rays can still penetrate the skin on cloudy days and during the winter, so it is important to protect your skin every day.
