Question

How does sunscreen work?

Answer 1

[AI-generated answer — Bot GPT 3.5]

Sunscreen works by either absorbing or reflecting the ultraviolet (UV) radiation emitted by the sun. The active ingredients in sunscreen create a barrier on the skin that blocks UV rays from penetrating the skin and causing damage. Some sunscreens contain chemical filters that absorb the UV radiation, while others contain physical filters such as zinc oxide or titanium dioxide that reflect the radiation away from the skin. By applying sunscreen to exposed skin, individuals can protect themselves from sunburn, premature aging, and skin cancer caused by UV radiation.
