Expose The Truth, Not Your Skin

Social media has fueled the spread of misinformation about sun safety and sunscreen. The rise of skin cancer myths can increase health risks and threaten public health. We’re here to set the record straight.

Myth: "Sunscreen causes cancer"                                                                      Fact: There is no medical evidence that sunscreen causes cancer. Concerns about sunscreen safety often stem from social media misinformation and misunderstandings of scientific studies. In contrast, UV radiation from the sun and tanning beds is a proven carcinogen linked to skin cancer. It is classified as a group 1 carcinogen, which is the same group as tobacco and asbestos.  

Myth: "Skin cancer only occurs on sun- exposed skin"                                            Fact: While skin cancer commonly appears on sun-exposed areas like the face, scalp, chest, arms, and legs, it can also develop in places that rarely see the sun. This includes the on or under the feet, between the toes, nails, and inside the mouth, ears, or eyes.

Myth: "Using sunscreen leads to a vitamin D deficiency"                                    Fact: While sunscreen may theoretically reduce vitamin D production by blocking some UV rays, studies show regular sunscreen users still maintain healthy vitamin D levels. Most people do not apply enough sunscreen to block 100% of UV radiation, and vitamin D can also be obtained through foods like fatty fish, eggs, fortified milk and cereal, or supplements if needed.

Myth: "You only need sunscreen on sunny days"
Fact: Up to 80% of UV rays can pass through clouds, meaning your skin can still be damaged on overcast days.
