Key Points:
- Dermatology physician's assistant Lauren Leavitt recommends choosing a sunscreen that is easy to wear consistently, with a lightweight, tinted SPF 30 sunscreen being ideal for daily facial use.
- SPF 30 blocks about 97% of UVB rays, and while higher SPFs offer slightly more protection, the increase is minimal beyond SPF 50.
- It is important to use a broad-spectrum sunscreen that protects against both UVA and UVB rays.
- Sunscreen should be reapplied at least every two hours, especially after sweating or swimming, to maintain effectiveness.
- To build a consistent sunscreen routine, keep the product in visible, frequently used places such as next to your toothbrush, at work, or in your bag.
