What are the key ingredients in sunscreen and how do they work?

Sunscreens typically contain active ingredients like zinc oxide, titanium dioxide, avobenzone, and octisalate. Zinc oxide and titanium dioxide are physical blockers that reflect UV rays, while avobenzone absorbs UVA rays. Octisalate helps stabilize other ingredients.

Are there any harmful ingredients I should avoid in sunscreen?

Yes, some ingredients like oxybenzone and octinoxate have raised concerns due to potential hormonal effects and environmental impact. It's best to look for mineral-based sunscreens with zinc oxide or titanium dioxide.

How do I choose the right SPF for my skin type?

Choosing the right SPF depends on your skin type and sun exposure. Generally, SPF 30 is recommended for most skin types, but if you have fair skin or plan to be in the sun for extended periods, consider SPF 50 or higher.

Can I use sunscreen on my face and body?

Yes, you can use sunscreen on both your face and body. However, look for formulations that are specifically designed for the face, as they may be lighter and less likely to clog pores.
