About sun protection:
- Sunscreen should be applied throughout the year, on cloudy and sunny days.
- Don’t think that you can just wear a sunscreen umbrella without applying sunscreen. UV rays will be reflected in all directions when they reach the uneven ground, and they will just be reflected on your face.
- You must use enough sunscreen, otherwise, the sunscreen effect will be greatly reduced. The correct amount is the size of a dollar coin. Sunscreen of different textures can be adjusted accordingly.
- The foundation with SPF cannot replace sunscreen, and its protective ability is not enough.
- Sun protection is important because it not only prevents sunburn, it also prevents you from getting old.
- When you have skin problems or sensitivity, you should also do sun protection. If it is not convenient to apply sunscreen, you can choose to do physical sunscreen.
- Apply sunscreen 15 minutes before going out to allow time for the sunscreen to form a film and provide better sun protection.
