- Sunscreens primarily come in two types based on their active ingredients: chemical (e.g., avobenzone, oxybenzone) and mineral (e.g., zinc oxide, titanium dioxide).
- Mineral sunscreens are generally recommended for children and people with sensitive skin, including those with eczema, because they are less likely to cause rashes or skin irritation.
- Mineral sunscreens work by creating a physical barrier on the skin surface that reflects and scatters UV rays without penetrating the skin.
- Chemical sunscreens absorb UV rays and convert them into heat, which is released from the skin, requiring sometime after application to become effective.
- Some sunscreens include added fragrances or other ingredients that may irritate sensitive skin; avoiding these is important.
- Mineral sunscreens provide immediate protection, tend to be safer and gentler for sensitive skin, and do not have the concerns about absorption into the bloodstream that some chemical sunscreens have.
- Proper sunscreen use (sufficient amount and regular reapplication) is essential regardless of type for effective sun protection.
Mineral vs Chemical Sunscreen
Mineral sunscreens are safest for kids and sensitive skin, but all sunscreens need proper use to protect.
