broad spectrum sunscreen
Means that the sunscreen product has been shown to protect against both UV-A and UV-B radiation of the sun.
Broad spectrum sunscreen refers to a type of sunscreen that provides protection from both UVA and UVB radiation. UVA radiation causes skin aging and is linked to skin cancer, while UVB radiation causes sunburn and is also linked to skin cancer. Broad spectrum sunscreen helps protect against both types of radiation and is recommended for daily use to reduce the risk of skin damage and skin cancer.
When choosing a broad spectrum sunscreen, you should look for one that has an SPF (Sun Protection Factor) of at least 30 or higher, which means it will provide protection against approximately 97% of UVB radiation. Additionally, certain ingredients such as titanium dioxide and zinc oxide have been shown to provide protection against UVA radiation as well.
It’s important to apply broad spectrum sunscreen generously, and to reapply every two hours when outside or after swimming or sweating. It should be applied to all exposed skin, including the face, ears, neck, arms, and legs.
Overall, using a broad spectrum sunscreen can greatly reduce the risk of skin damage and skin cancer caused by prolonged sun exposure.
