In summer, when the thermometer exceeds +25C, cosmetics undergo a series of changes. Cosmetics and makeup products are similarly affected by the humid air that forms in the bathroom after taking a hot shower. For cosmetics to last longer, they should be kept in the refrigerator, because the coolness prolongs their life, and in some cases improves their properties. True, not all beauty products are recommended to put on the shelves of indispensable in the household unit, this aspect depends largely on the composition and other characteristics. What products can not survive the heat? And which can be left on the dressing table?
Why doesn’t face cream belong on a shelf in the bathroom?
Constant temperature fluctuations, steam emissions and high levels of humidity in the room are the most dangerous enemies of cosmetics, and face cream is no exception to the list. The above parameters often contribute to the rapid spread of bacteria, especially when natural ingredients are involved. Direct sunlight, as well as electric light, is also detrimental to the cream. They activate a variety of chemical reactions, including oxidation processes, and as a consequence, changing the texture of the cream, reducing its effectiveness, and sometimes make it unsafe for sensitive skin.
Face cream should always be stored in the refrigerator on the bottom shelf. This way you can extend its shelf life and enjoy the results claimed by the manufacturer. When buying a cream and resorting to its use, always read the storage conditions. These are usually found on the back of the bottle or jar. A bottle fitted with a pump dispenser is best. Such packaging does not allow you to touch the contents of the container, and only squeeze the desired portion of the cream, because even on the hands accumulates a considerable number of bacteria that can lead to failure of the consistency.
Where to store cosmetics against puffiness and bags under the eyes?
Cosmetics designed to relieve puffiness, bags and bruises under the eyes are usually endowed with toning and cooling components. Such products can be stored in a dark place or a room equipped with a climate control system, but in no case on the dressing table near the window. If eye area cosmetics do not contain the ingredients listed above, it is better to keep them in the refrigerator. Firstly, it will retain its original properties; secondly, it will increase the cooling effect on the skin and thus minimize puffiness and other troubles.
Pharmacy cosmetics aimed at the treatment need coolness
Cosmetics intended to provide a therapeutic effect, such as eliminating acne, require a certain temperature regime, and most often – no higher than 12C. It is not possible to maintain such a regime in room conditions, and there is only one solution: the refrigerator. If you do not observe the parameters of storage, medical cosmetics simply cease to work, and perhaps even bestow a new batch of rashes and other ailments. A similar situation is with cosmetics containing ascorbic acid (also known as vitamin C). It is also recommended to keep in the refrigerator, otherwise it is subjected to rapid oxidation and, consequently, deterioration.
Does the scent of the perfume open at low temperatures?
There is an opinion that the perfume, or rather its fragrance, is disclosed when stored in a cool place, while the heat and even more so direct sunlight enhance the evaporation of the perfume and contribute to the volatility of the top notes, respectively, change the formula and the scent itself, which is often transformed is not in the best way. But at the same time, the advice that says that the perfume should be kept in the refrigerator is untrue! After all, too cold air contributes to changing the formula.
Perfume should be stored at room temperature, but in a dark place, such as in a closet. And it’s better to pay tribute to the packaging, equipped with a dispenser-sprayer. In such a container perfume components are not exposed to damaging chemical reactions due to lack of oxygen access, in addition, they do not evaporate and do not endow the nearby objects and facilities with their scent. It is important to remember that the shelf life of the perfume does not exceed one and a half years, after this period the bottle should be thrown in the trash, because at the end of its shelf life it acquires strong alcoholic and bitter notes, which, alas, do not give a zest to the image.
Where to store handmade cosmetics?
Some people prefer to make their own cosmetics, but it can not boast a long shelf life because it does not contain preservatives. So, homemade tonic created on the basis of green tea or decoction of chamomile flowers should be stored in a tightly closed container in the refrigerator for no more than two days. If stored in the same composition at room temperature, it will quickly lose their beneficial properties. Yes, and cool tonic is much more useful and effective for the skin than warm. It instantly eliminates puffiness and makes the skin look fresher. In addition, it will be a real salvation for the skin in the heat.
Homemade creams and masks should be kept only in the refrigerator in a closed container. Shelf life, in turn, depends on what created a particular cosmetic. For example, products based on milk products can not be stored, the maximum exposure in the refrigerator for 3-4 hours if there is no time for care or change of plans immediately after cooking. If the homemade mask contains natural vegetable and essential oils and nothing else, it can be kept in the refrigerator for 7-14 days. But it is important to remember that some oils at low temperatures change their consistency – they become solid or form a flaky residue.
