On the one hand, cosmetic products often have a small shelf life, from six months or longer. On the other hand, as well as something edible, they can be spoiled by improper storage or use.
First of all I want to say a few words about the expiration date. Of course, when buying cosmetics, you need to pay special attention to it, and during use all the more.
I must say that if you bought a lipstick yesterday and it says that it is valid until January 2017, do not be in a hurry to rejoice. Expiration date indicates how much this type of cosmetics may be in order in closed form.
When you print out a tool, many more factors come into play: temperature and storage location, contact with air, correct / incorrect use. These factors usually shorten the actual deadline, even if you are doing everything right. And if not, then all the more.
The standard shelf life of ink after opening is 6 months. This is when it is kept at room temperature, by no means somewhere near the batteries. And when washing the brush with soap and water once a month.
It seems to me that very few people use it that way, especially if the cost is high. In general, nothing. Many people think that after half a year the mascara simply glues the eyelashes and forms lumps. This effect is, but it is not important. I must say, the danger is different: you can get conjunctivitis and a lot of eye and eyelid diseases if you use it longer.
Shadows, powder, blush
For these funds is also the best room temperature. Hypothermia and overheating are equally harmful to them.
If the structure of shadows, powder and rouge is friable, then the term can be as much as three years! And if creamy, then much less, about a year and a half.
A very important addition. To use these tools for a specified time, you need to monitor and carefully process or replace applicators, brushes, and sponges.
Many lipsticks also have a long shelf life, up to three years. Only this again in sealed form. I must say that open lipstick is very vulnerable. She is afraid of contact with air, so you need to store it only with the cap closed.
The sun’s rays are most harmful to her. Even if the tube is dark, and it stands where direct sunlight falls, it will deteriorate in three months.
Of course, its texture will deteriorate, it can become an unpleasant smell. Only, as in the case of mascara, this is not the most deplorable. What is worse is that the oils in its composition go rancid. As a result, lipstick begins to release toxins that are harmful to the lips and to overall health.
So, my dear, in this case it is better not to save, and then more money will be spent on treatment from all sorts of unpleasant things! And how much more time it will take to determine exactly what you have and what arose from! Quiet horror. No need to arrange it yourself.
