Why does skin damage when exposed to the sun?
If you’ve read our post about photoaging, you’ll know that when you expose your skin to the sun, skin cell DNA absorbs the UV radiation, which causes structural changes to the genetic information. This can cause genetic mutations if our cells are unable to repair the damage. Unfortunately, this is the case for individuals with XP; they are unable to repair the DNA damage due to a genetic deficiency, and this can lead to skin cancer.¹
