Martin Lewis urges UK households to always write on their sunscreen bottles

Martin Lewis has offered an important to tip for Britons returning from their holidays that could save you money. The financial journalist, broadcaster, and founder of MoneySavingExpert.com, is known sharing an array of small and big ways people minimise costs.

One of his most recent hacks is about sunscreen, which many Britons may still have at home from their last holiday, or thrown away - not knowing how long they can be used for. Today, Lewis shared a clip from an appearance on This Morning on X, writing "Why you should write on your Sunscreen bottle!"

In the video, the personal finance guru picks up a bottle of it and says: "Go to the back of your suncreen [bottle], and you will see this," pointing to the "period after opening" date.

On the bottle he has it says 12M, which he explains means it is still safe to use for 12 months after you've opened it.

"So if you've opened a new one this summer, write the date you opened it, on it."

And that way you don't have to throw it away, and can "still use it next summer".

When suncreen has expired it may be less effective, and may not provide protection from damaging rays.

Sunscreen that's been languishing on the shelf too long may also separate, become watery, or lumpy, a warning sign that you need to bin it.

As well as preventing a painful sunburn, using screen is also vital for protecting yourself against serious health issues.

In the UK, melanoma skin cancer rates, primarily caused by ultraviolet (UV) radiation, have increased by 32% in the UK over the past decade, the National Institute for Health and Care Excellence (NICE) says.

Cancer Research UK has said the number of new cases on average each year is predicted to continue increasing by 9%, resulting in some 26,500 cases in 2038-2040.
