Do all skin tones need SPF?Updated a year ago

Yes, SPF is essential for all skin tones. UV radiation from the sun affects everyone, regardless of their skin colour. While individuals with darker skin tones naturally have more melanin, which provides more protection against UV rays compared to lighter skin tones, they are still at risk of sun damage.

Prolonged UV exposure can cause melanocytes (cells that produce melanin) to become overactive, leading to the production of excess melanin. This can result in hyperpigmentation, such as dark spots or patches on the skin. 

For individuals with deeper skin tones, melanocytes may produce more melanin or distribute it unevenly across the skin, leading to the appearance of dark spots or patches.
