The sun is coming out and spirits are lifting higher. But the same sun that boosts our mood is also the culprit behind skin cancer.

Melanoma, the most dangerous form of skin cancer, will affect more than 100,000 people in the United States in 2020 and almost 7,000 Americans will die from it, according to the American Cancer Society .

Luckily, we have sunscreen to protect us. But can some sunscreens be just as dangerous as the sun? Food and Drug Administration data show that chemicals in sunscreens are absorbed into the human body at levels high enough to raise concerns about potentially toxic effects, while websites like Goop now tout their lists of non-toxic sunscreens .

With that in mind, HuffPost spoke to experts to clear up the most common myths and help you understand the importance of sunscreen.

How Sunscreen Works

A broad-spectrum sunscreen stops the suns rays from entering and damaging your skin, particularly UltraViolet A and B rays, most commonly referred to as UVA and UVB rays. UVA is what causes aging (photoaging) and UVB causes burning . UVA rays can cause genetic damage to cells and penetrate deeper than UVB.

There are two basic types of sunscreen: chemical and physical . Simply put, chemical sunscreens are those that contain chemicals. Were talking things like octylcrylen, avobenzone and octinoxate. Physical sunscreens use natural agents like zinc and titanium oxide.

Myth #1: The SPF protection of foundation or face cream is enough

Unfortunately, for many people this isnt true.

Dermatologist Jessica Weiser said, Generally, makeup contains SPF 15-25 and is not applied in adequate quantities to provide even the amount of sun protection advertised on the bottle. To properly protect against the sun, a standalone sunscreen with broad-spectrum UVA/UVB coverage and an SPF of 30 or higher should be applied underneath makeup.

Yannis Alexandrides, a plastic surgeon who founded a line of skin products , added the only way makeup would provide enough protection would be to layer so much that itd be impossible to look presentable. You need around eight times the normal amount of foundation to get the correct sun protection, which isnt realistic or good for your skin, he said.

Myth #2: You dont need sunscreen in the winter

Another common myth is that you only need to wear sunscreen when its warm and the sun is out in full force. But UV rays are present at all times during the day, and its important to wear sunscreen year-round : The only time that skin is not exposed to UV is after sunset and before sunrise when it is dark outside, Weiser said.
