As the clocks spring forward and brighter days arrive, many Brits are preparing to dig out their sunscreen from the back of the cupboard. However, health specialists are issuing a crucial warning: simply applying old sunscreen might not provide adequate protection, and consumers should not take the risk.
Understanding the PAO Symbol
Posting on the Which? Instagram feed, a skincare expert emphasised the importance of a specific symbol found on cosmetic products like sunscreen. The specialist stated, "Heading out into the sun this summer? Then you cannot afford to ignore this symbol."
The symbol in question is the Period After Opening (PAO) jar icon, which indicates how many months a product remains effective after being first opened. Typically, sunscreens have a PAO of 12 or 24 months.
Practical Tips for Consumers
To avoid confusion, the expert recommended a simple method: "Now, I'm never going to remember that, so I always write the date in marker pen on the side." This practice helps users track when the product was opened and when it should be replaced.
The advice is clear: if the sunscreen is past its use-by date, do not risk using it. Instead, purchase a new bottle to ensure optimal protection against harmful ultraviolet rays.
Martin Lewis's Money-Saving Advice
Last year, financial expert Martin Lewis highlighted this issue on his platform. He explained, "As we're racing towards the summer just a quick tip on sunscreen, when you get your sunscreen turn the bottle around because on the back you'll see a PAO number."
Lewis elaborated that PAO stands for period after opening, denoting how long the sunscreen will continue to provide protection once opened. He advised consumers to note the opening date on the bottle to avoid unnecessary waste.
"So then when you do open it, put a little note of what date, write that onto the sunscreen and you'll know if you try to use it in a year's time whether it's still valid or not," Lewis said. He added that this approach can save money, as products with a 24-month PAO might still be usable the following summer, preventing premature disposal.
Why This Matters
Using expired sunscreen can compromise its effectiveness, leaving skin vulnerable to sunburn, premature ageing, and increased risk of skin cancer. The active ingredients in sunscreen degrade over time, especially after exposure to air and varying temperatures.
Experts stress that checking the PAO symbol is a simple yet vital step in summer safety routines. With warmer weather approaching, ensuring your sunscreen is within its effective period is essential for maintaining skin health.
This warning comes as many households prepare for outdoor activities, highlighting the need for awareness about product safety beyond just the purchase date. By following these guidelines, Brits can enjoy the sun responsibly while protecting their skin and their wallets.
