The best type of sunscreen is a physical (mineral) sunscreen.
Why Choose Physical Sunscreen?
Physical sunscreens offer superior protection because their active ingredients, zinc oxide and/or titanium dioxide, sit on top of the skin and create a physical barrier against the sun's harmful ultraviolet (UV) rays. Unlike chemical sunscreens, they don't absorb into the bloodstream. This makes them a safer choice for everyone, especially sensitive skin types, babies, and children.
While they may appear thicker and leave a slightly whiter cast initially compared to chemical sunscreens, advancements in formulation have led to many aesthetically pleasing options. They are also generally considered gentler on the skin.
Understanding Sunscreen Types
- Physical (Mineral) Sunscreens: These use zinc oxide and/or titanium dioxide to block UV rays. They are generally considered safer and better for sensitive skin.
- Chemical Sunscreens: These use chemical filters that absorb UV rays and convert them into heat. While effective, some chemical filters have raised concerns regarding absorption into the bloodstream.
Choosing the Right Sunscreen
When selecting a sunscreen, regardless of type, look for these key features:
- Broad-spectrum protection: This means it protects against both UVA and UVB rays.
- SPF 30 or higher: This indicates the level of protection against UVB rays.
- Water resistance: Choose a water-resistant formula if you'll be swimming or sweating.
Remember to apply sunscreen liberally 15-30 minutes before sun exposure and reapply every two hours, or more frequently if swimming or sweating.
