Health | Does expired sunscreen still work?

It's that point of 12 months when everyone looks forward to a little bit of fun within the sun. However, an excessive amount of sun may be dangerous. The sun's UV rays damage the skin. Children are especially in danger as they spend more time outdoors and may easily get sunburnt.

Throw away the bottle if three years have passed because the purchase date.
