Summer facts
Why do we freckle in the sun?

freckles

It's that time of year where freckles begin to appear across our faces. But why do freckles come out in the sun and are they a sign of sun damage?

Freckles are generally caused by genetics and stimulated by ultraviolet (UV) light. If your skin isn't protected, exposure to sunlight causes the production of melanin that protects the skin and leads to the appearance of more freckles.

People with lighter skin and hair pigments are more likely to see freckles on their faces and arms as they produce more melanin to shield themselves from sun damage.

Most of the time, freckles are harmless and not a sign of sun damage, however if they become significantly darker after exposure or begin changing in size or shape, this could be a sign of sun damage and an increased risk of skin cancer.

Our app has a UV forecast with all the info you need to stay safe this summer.
