Does skin care really belong in the fridge?

Various cosmetics in a small refrigerator with open door

Do you keep your skincare in the fridge to extend shelf life, for example? Better don't. Again and again we hear that skin care products are stored in the refrigerator. If you have already read our article about preservatives , you know that a product cannot go bad because it is "only" stored at room temperature. Then it should not have been approved at all, because then the product would not have passed all the stability tests required by law.

Ingredients that belong in the refrigerator

Of course, there are products that - kept in the refrigerator - can enhance or preserve their effect, such as a decongestant gel or a refreshing toner. Here it makes perfect sense to apply the product slightly chilled. There are also ingredients, such as free vitamin C (Ascorbylic Acid or Ascorbic Acid), which should be kept refrigerated because they are very unstable. This active form of vitamin C should also be consumed quickly, otherwise it simply loses its effectiveness. By the way, you will hardly find ascorbic acid in a cream - it is extremely reactive and unstable, which is why vitamin C is usually offered in serums or people use much more stable vitamin C derivatives. Other ingredients like vitamin A can also lose their effectiveness if you expose them to very high temperatures of over 40 degrees for several months.

Therefore, rather than storing the product in the refrigerator, it is better to use it up quickly, not to buy large package sizes, and also to tend to use manufacturers who produce in small batches.

Oils in the refrigerator?

Products that use oil in their formulation or are based on oil do not belong in the refrigerator, because the oil can change its texture. It becomes cloudy, flocculates or thickens. Also, particularly high temperatures over a long period of time and permanent exposure to sunlight are not good for an oil. Although an oil with antioxidants generally lasts longer than one without, it can also become rancid.

Particularly sensitive: UV filters

In fact, sun protection products or the filters used are often particularly sensitive. Especially chemical complex UV filters (a modern sun protection product usually even combines several UV filters) do not like cool temperatures - certainly not those in the refrigerator. They can crystallize or break down. By the way, this is also the reason why our D-FENCE 50 should not be stored in the refrigerator. Very high temperatures are also not good for some UV filters. They do not lose their effectiveness immediately if they have been on the beach a few times and have been in the blazing heat (or light) for several hours. But to be on the safe side, you should rather not use these products on your next summer vacation or assume that the SPF is still achieved as stated. Better use a new product.

Overall, you can remember: HighDroxy products should not be stored in the refrigerator, storage at room temperature is absolutely sufficient. Our products are produced in comparatively small batches, hygienically packaged and distributed directly. So you have to worry about Do not worry about the shelf life and effectiveness of the ingredients.
