Is chemical sunscreen safe?

What is chemical sunscreen?

Chemical sunscreen uses filters such as avobenzone, oxybenzone or octinoxate to absorb ultraviolet radiation, also called UV. Mineral sunscreen uses zinc oxide, titanium dioxide or both. Hybrid sunscreens combine chemical and mineral filters; the active ingredients section tells you which type you have.12

Chemical sunscreen is generally lighter and easier to spread than mineral sunscreen. Chemical sunscreen is usually transparent on skin, so sun protection does not have to announce itself in white.1

Is sunscreen safe to use?

Sunscreen helps prevent sunburn, premature skin aging and skin cancer. Repeated UV exposure contributes to lasting skin damage, so protection matters beyond avoiding a visibly red face. Chemical, mineral and hybrid sunscreens can all provide effective protection when they offer broad spectrum coverage, SPF 30 or higher and water resistance.23

Some chemical sunscreen ingredients can enter the bloodstream, and questions about their absorption remain a safety concern. Mineral filters offer an alternative: zinc oxide and titanium dioxide were regarded as safe by the FDA in 2019. If you are concerned about a particular ingredient, discuss it with a dermatologist rather than abandoning sun protection.1

For sensitive skin, mineral sunscreen is the preferred starting point because it is less likely to cause irritation or allergic reactions. Chemical sunscreen can also burn if it gets into your eyes. If a sunscreen causes irritation or a rash, choose an alternative and discuss the reaction with a healthcare professional.14

How should you use chemical sunscreen?

1. 1Choose broad spectrum SPF 30 or higher with water resistance. Broad spectrum means protection against both UVA and UVB.
2. 2Apply generously to dry, exposed skin before going outdoors. Allow 30 minutes before sun exposure, and follow the product's directions.
3. 3Cover your face, ears, neck, hands and other uncovered areas. Most adults need about an ounce to cover exposed skin; body size affects the amount needed.
4. 4Reapply at least every two hours outdoors and after swimming or sweating, following the package instructions.
5. 5Use shade, protective clothing, a hat and sunglasses as well. Sunscreen is not a reason to spend longer in the sun.

What is the best chemical sunscreen for your face?

Pick by protection and texture rather than the chemical label alone. Creams suit dry skin and facial application; gels suit oily skin. A sunscreen you like enough to use is more useful than one you admire from a safe distance on the bathroom shelf. Mineral sunscreen is the better starting choice if sensitivity is your main concern.2

For children, zinc oxide or titanium dioxide products are preferred because they are less likely to irritate young skin. For babies younger than six months, prioritize shade and clothing, and speak to a pediatrician before using sunscreen.4
