Basically, UV radiation fuses adjacent thymine bases in your DNA, creating these dimers. If your body's repair mechanism fails to fix them, it leads to mutations that can cause skin cancer.

When my doctor explained skin lesions to me, he mentioned that solar UV rays cause molecular-level DNA damage that the skin fails to repair. This is why daily sun protection is a medical necessity, not a beauty tip.

These dimers distort the natural shape of the DNA chain, making replication prone to errors. Over years of repeated sun damage, these errors accumulate and can turn cells malignant.

It sounds very technical, but it basically means sun exposure damages the skin's genetic code. Please make sure your kids wear sunscreen and hats whenever they play outdoors in the afternoon.

This scientific explanation of UV damage is so scary to read. Does anyone else get anxious about spending too much time outdoors under the direct sun?
