Which skin type is characterized as "extremely fair" and is common among Northern Europeans?

The skin type characterized as "extremely fair" and commonly found among Northern Europeans is indeed skin type 1. This classification describes individuals who typically have very light skin that may burn easily and rarely tans. People with this skin type often have light-colored hair (blonde or red) and light eyes (blue or green).

Skin type 1 is at the highest risk for sunburn and skin damage due to UV exposure, making it crucial for individuals with this skin type to take protective measures when in the sun. Understanding this classification is essential for providing appropriate guidance on sun safety and tanning practices, as those with skin type 1 need to be particularly careful to avoid excessive sun exposure and understand the importance of using broad-spectrum sunscreen.
