Sunscreen is like a “separate object” of beauty lovers. Subjectively not carefully preserving the product will sometimes lead to consequences such as hidden acne, itching, irritation and more seriously, dermatitis. So how to store sunscreen effectively? How to recognize expired sunscreen correctly? Let’s find out in today’s article with Paula’s Choice Vietnam.
How long can sunscreen last?
Before learning how to store sunscreen , we want you to better understand the shelf life of the product. How long does a tube of sunscreen last? Most sunscreen products on the market today have a shelf life of 2-3 years . This is the expiry date printed on the package, in storage conditions at room temperature and unopened to use. For products that have been used and stored at room temperature, the maximum open date is 12 months .
So is it okay to use an expired sunscreen? Their answer is NO ! You should not use expired sunscreen. What if you keep using an expired sunscreen?
Scientific studies have shown that the lower the SPF number , the greater the risk of using an expired sunscreen. A tube of SPF 15 sunscreen may have the same active ingredients as an SPF 50 tube, but an SPF 15 tube will have a lower concentration of active ingredients. Therefore, by the end of its shelf life, that SPF 15 tube may have lost almost all of its ability to protect the skin from UV radiation from the sun . Continued use may cause irritation, pimples, melasma and freckles . More seriously, using expired sunscreen is one of the ways that mold and bacteria grow, causing skin inflammation and is difficult to treat and recover.
How to recognize expired sunscreen?
For products that have been used but do not remember the exact time of opening the lid, it becomes difficult to recognize the expired sunscreen. Or due to improper storage of sunscreen , the product may be damaged before its expiration date.
There are many ways to tell if a sunscreen is broken or past its expiration date. Here are 3 ways to know for you:
- The color of the cream: With cream sunscreen products, it will be most obvious because the color is yellowish or slightly cloudy compared to normal.
- The texture of the cream will be thinner. In some broken sunscreens, the product may become waterlogged.
- A pungent, unpleasant odor appears.
Instructions for 3 ways to store sunscreen
To preserve sunscreen most effectively, you need to pay attention to a few notes below:
1. Store at room temperature
Leaving sunscreen products at room temperature is one of the ways to preserve sunscreen for a long time that experts recommend. Sunscreens are out of date or damaged because their active ingredients break down over time.
The effectiveness of a product’s sunscreen depends on many factors. High temperatures plus sunlight easily break down the active ingredients that protect against UV rays, making the sun protection effect significantly reduced. This will also happen when the product is stored at room temperature, but at a much slower rate. This is why you should store your sunscreen at room temperature and avoid direct sunlight.
2. Close the cap of sunscreen immediately after use
When it comes to instructions on how to store sunscreen, it is impossible not to mention an important note that is to cover the sunscreen immediately after use . The cap of the product helps to minimize oxidation as well as prevent dirt and bacteria from entering and changing the sunscreen.
3. Sunscreen can be stored in the refrigerator

This is a pretty good and effective tip that many beauty believers often pass on to each other to prolong the use of sunscreen. Sunscreen will keep better quality if stored in the refrigerator, especially in the summer.
To store sunscreen in the refrigerator most effectively, you should apply some of the following rules:
