Sunscreens help protect against the sun's damaging effects. Sunscreens are topical agents which can be used to block the sun's UV rays and can be used to prevent photoaging.
Sunscreens can block the UV rays or absorb them before they reach the skin.
What properties are important for molecules used as sunscreens?
No, not all sunscreens offer the same level of protection. Different sunscreens have varying SPF (Sun Protection Factor) levels and protection against different types of UV rays (UVA and UVB). It's important to choose a sunscreen with an SPF of 30 or higher and broad-spectrum protection for optimal sun protection.

Mineral Physical Sunscreens: Particularly Zinc and Titanium Dioxide. They offer UVA and UVB spectrum coverage, and do not pose risks to your health like chemical sunscreens.

Ozone irritation occurs in the presence of ozone. It can be avoided by sunscreens.
Sunscreens contain ultraviolet (UV) filters which protects the skin from the ultraviolet A (UVA) and ultraviolet B (UVB). Exposure to ultraviolet radiation can cause sunburn and skin cancer. Sunscreens absorb or reflect the radiation, and therefore protect the skin.
