Sunscreen is an essential product for protecting the skin from the harmful effects of the sun. Sunscreens contain active and inactive ingredients that work together to provide protection from the suns harmful UV rays. The active ingredients in sunscreens are the ones that protect the skin from the suns harmful UV rays, while inactive ingredients are all other ingredients that are not active ingredients, such as water or oil that may be used in formulating sunscreens.
There are two types of sunscreens: chemical and physical. Chemical sunscreens contain active ingredients such as avobenzone, oxybenzone, octinoxate, octisalate, and Padimate O. These chemical compounds have been approved by the FDA, but research shows that they are systemically absorbed into the body after one use. On the other hand, physical sunscreens contain active ingredients such as titanium dioxide and zinc oxide. These ingredients work like a literal shield on top of the skin and are not absorbed into the skin.
When choosing a sunscreen, it is important to look for a broad-spectrum sunscreen that protects the skin from both UVA and UVB rays. The SPF (Sun Protection Factor) of a sunscreen indicates the level of protection it provides against UVB rays. Sunscreens with an SPF of at least 15 are recommended by the FDA.
It is also important to read the label and check the ingredient list, especially for those with sensitivities or allergies. Those who are acne-prone or have more sensitive skin on the face may require a different sunscreen for the body and face. Tinted sunscreens contain iron oxide, which research shows helps protect peoples skin against the negative effects of visible light from the sun.
In summary, when choosing a sunscreen, it is important to look for a broad-spectrum sunscreen with an SPF of at least 15. It is also important to read the label and check the ingredient list, especially for those with sensitivities or allergies.
