Common Misconceptions About Sun Protection Factor Debunked

When it comes to staying safe under the sun, we need to clear up some myths. Many think the sun’s heat is what hurts us. But it’s really the invisible UV rays that cause damage, not the temperature. So, even on a cloudy day, your skin could be at risk because UV rays go through clouds.

What is SPF?

SPF measures how effective a sunscreen is at stopping UVB rays from burning the skin. The higher the SPF, the more protection you get from sunburn. A sunscreen with SPF 30 or higher is best. It can block up to 97% of the UVB rays. But remember, SPF doesn’t tell us about UVA protection, which is also important for avoiding skin damage and cancer.

Skin Cells in Trauma

But, this doesn’t mean the skin is fine. The skin is actually in trouble, and it’s trying to save itself from UV harm. Too much sun can make things worse. It can hurt our DNA more, raise the risk of skin cancer, and speed up signs of photoaging.
