The dangers of using expired sunscreen

The dangers of using expired sunscreen

It may be hard to toss leftover sunscreen in the bin, but it’s important to consider the effect old sunscreen can have on your skin.

Most sunscreens are consumed within a relatively short period of time, however, with infrequent use, some products can last for years. Sunscreen does not spoil that quickly and can have a shelf life of up to three years if not indicated otherwise by the manufacturer. There are brands that have an expiry date printed on the label, which is the assurance from the manufacturer regarding the quality and effectiveness of the product for a certain time.

It is important to know and stick to the expiration date on your sunscreen. Applying sunscreen that has lost its original strength means your skin is not reaping the full benefits of the product’s sun protection properties.

This is because after the expiry date, the active ingredients begin to break down and the SPF rating stamped on the container degrades. Chemical sunscreens made with ingredients such as oxybenzone can oxidize once you’ve opened and exposed them to air, which is accelerated if you’ve stored them in a warm or humid place. When the formula no longer works like it used to, wearing it puts you at risk of sunburn, sun damage, brown spots and skin cancer development.

Mineral-based sunscreens, those that contain zinc oxide or titanium dioxide on the label, are chemically inert and should remain effective in the long-term. However, over time it degrades differently: additives break down and separates ingredients to the point where the sunscreen becomes a watery or grainy mess. Expired mineral sunscreens can also change colour or develop a funny smell.

Moreover, any leftover sunscreen that has been opened and closed for years can become contaminated with bacteria and mold, which, when applied to the skin, can result in allergic reactions, irritation, and skin infections.

With as many different sunscreen brands on the market as the various compositions of active and inactive ingredients in them, it can be difficult to gauge the effectiveness of an expired product, especially considering the storage history of an individual container.  

A good rule of thumb when trying to figure out if you should toss out an expired product is if it does not look, smell or feel the way it did when you first applied it to your skin, you’d be better off throwing it away. However, it would be far safer if you buy a single-use product like our sunscreen snap sachets. Not only do they provide optimal protection, but you also don’t need to worry about bacteria growing on an opened bottle stored in your bathroom cabinet.

Tricks to treat sunburn quickly and effectively

Tricks to treat sunburn quickly and effectively

While some people may regard sunburn as just a temporary skin irritation, according to the Skin Cancer Foundation, sunburns can result in lifelong damage to the skin. Not only does a sunburn increase your risk of developing cancer, but it can be extremely unpleasant. Here are three ways in which you can alleviate the pain and soothe the burn quickly and effectively.

Cool the burn

As soon as you notice red skin you should cover up and get out of the sun immediately. You must then act fast to cool the burn down. You can reduce the inflammation by taking a cool shower or bath, or you can use ice to cool the burn, but ensure you don’t apply ice directly to the affected area.

Avoid wearing tight clothes

Wear only loose clothing while your skin is replenishing itself because tight clothes can irritate sunburnt skin. Wearing loose fitting clothes will allow your skin to breathe and speeds the healing process.

Drink lots of fluids

Burns result in fluid being drawn away from the rest of the body to the skin’s surface, so it’s important to rehydrate by drinking a lot of water, including sports drinks that help to restore electrolytes.

Apart from the three we’ve mentioned, there are several other hacks for treating sunburns. Sprinkling baking soda to lukewarm bath water can also relieve the pain – baking soda has a higher pH level, so it’s effective at balancing the lower pH level of sunburnt skin. By keeping a few EezySun snap sachets in your bag you can avoid suffering burns in the future, and make applying sunscreen very convenient and hassle-free.
