A mini heatwave is imminent, which means we're all doing the same thing: an SPF stock check, reaching for whatever is already lingering at the back of the bathroom cupboard. You might find a half full bottle of SPF mist that travelled back with you from your last jolly, or that extra bottle you packed before your last flight away that never got opened. Whatever you're about to use, make sure to properly assess whether it's likely to have expired. If you have unwittingly let your sunscreen go off, it will afford you zero protection under the sun.
So: how long does your sunscreen last before it expires? Here's, everything you need to know before you apply your cream slapdash.
If Your Sun Cream Has Not Already Been Opened
This is key. If your sun cream has already been opened, it's likely to be oxidised to some degree, which affects its performance.
According to Ultrasun, products that have an expiration date of less than 30 months after the date of production have to state it on the packaging. If you can't find anywhere stating its expiry date, the safest option is to consider it safe to use for the 25 months after the date you can remember buying it. That 5 months leeway affords for any inaccuracies in estimating the purchase date, as well as the gap between production of the product and the moment you bought it. Remember, this is only relevant if the product is 100% unopened.
If Your Sun Cream Has Already Been Opened
To use an example, NIVEA guarantees the product quality of their sun protection products for 12 months after opening. That is providing the bottle has been stored at room temperature, kept out of direct sunlight, and the product itself looks and smells normal. If you bought one of their sun lotions late last summer, say, August to September, you should be fine to use it the following April, even if it has been opened. If, however, you have doubts over whether it has been stored properly, or whether it smells or looks normal, any doubts at all, chuck it. No sun damage is worth the money you'll save by not buying a fresh bottle. Our personal rule of thumb? If you're even beginning to deliberate, buy a new one. Remember, even if your last holiday was less than six months ago, the likelihood is that that particular bottle of sun cream was baking in a beach bag for a good percentage of your trip - that doesn't count as room temperature storage. Always err on the safe side.
