When you see that the expiration date of the cosmetics you have put aside is still far away, do you feel relieved? Don't be too happy too soon! Because as soon as the cap of these cosmetics is unscrewed, its life span begins to count down. For example: the bottom of the bottle of facial cream is printed with the words "24M", which means that if it is "properly" stored after opening the cap, it can be kept for up to 24 months. How to keep cleaning products fresh? Key tip: Don’t go into the bathroom 1. For the sake of convenience, facial cleansers, shower gels and shampoos are placed on a shelf next to the bathtub or shower head, which can easily cause water to enter the cleaning products and the shower gel or shampoo to deteriorate quickly. 2. When unopened products are placed in the bathroom, high temperature and humidity can easily accelerate the growth of bacteria in cleaning products. 3. It is best to place cleaning products in a ventilated and dry place and bring them into the bathroom when taking a bath. Be sure to tighten the lid after each use and the storage period should not exceed one year. How to keep lotion fresh? Key tips: Make sure your cotton pad is clean 1. The cotton pad used to pour out the lotion does not look clean enough, which will definitely cause secondary contamination to the lotion. 2. Cosmetic cotton pads are generally not individually packaged. After unpacking the large box, be sure to remember to close the opening with a sealing clip after use. 3. Pay attention to the shelf life. Cosmetic cotton pads that have been stored for too long should not be used. How to keep sunscreen fresh? Important note: Keep out of direct sunlight! 1. Strong ultraviolet radiation can even deform the plastic tube packaging of sunscreen and release chemicals that are harmful to the human body. 2. High temperatures can also easily cause the oils and fragrances in sunscreen to oxidize, causing some sunscreen ingredients to lose their activity. How to keep the essence fresh? Key Tip: It is better to spend quickly than to save wisely 1. The active ingredients in essences that are prone to rancidity are much more than those in lotions and creams. If left for too long, they will become "skin-damaging liquid"! 2. In order to use up the essence while it is still fresh, it should be used continuously within a specified time period to improve skin quality to the greatest extent and avoid deterioration and waste. How to keep creams and lotions fresh? Key Tips: Do not put in the refrigerator 1. Too high a temperature will destroy the emulsion of skin care products, causing oil-water separation or rancidity, shortening the shelf life. 2. Too low temperature will cause the structure of creams and lotions to change, the water will freeze, the emulsion will be destroyed and the texture will become rough after melting, losing the original warm feeling and causing irritation to the skin. 3. The temperature difference in and out of the refrigerator will cause creams and lotions to deteriorate prematurely. How to keep eye cream fresh? Key Tip: Digging scoops can help you fight pollution 1. Eye cream cosmetics have a higher moisture content and more active ingredients. If exposed to the air for a long time, they are more likely to deteriorate. 2. From a hygiene perspective, choose eye cream that comes in pressed packaging to minimize the possibility of oxygen or microbial bacteria invading. 3. When using, be sure to scoop gently with clean fingers, or use a special small spoon to take a small amount. How to keep base makeup products fresh? Key Tips: The sponge puff should be clean 1. The shelf life of foundation products is generally one year after opening. In normal use, if you use a brush or sponge instead of your fingers to apply foundation, the shelf life of the foundation will be extended accordingly as long as you keep the brush or sponge clean. 2. For wet and dry powder, the powder puff should be cleaned after each use and air-dried before putting it back into the powder box. How to keep lip products fresh? Key Tips: Clean before use 1. The shelf life of lipstick is at least two years. Plant-based lip balm without chemical preservatives is best used up within 2 to 3 months after opening. 2. When you are sure that you will not use this color for a while, scrape off the used surface of the lipstick, then screw the lipstick into the tube and make sure the cap clicks tightly. 3. Keep in a cool place, away from direct sunlight which may cause the temperature to be too high, so as to avoid the lipstick melting and deterioration. 4. Remember to wash your lips with clean water before using lip balm, which can greatly extend the shelf life. How to keep eye makeup products fresh? Key Tip: Moisture and oxygen are the enemies 1. The shelf life of eyeliner is generally up to 3 years. If there are thin white spots on the tip of the pen, just gently scrape them off. 2. Eye shadow cream or eye shadow powder can be stored for 2 years. Pay special attention to the rainy season as eye shadow cream is prone to mold. 3. Once the mascara is unscrewed, the shelf life is only 6 months at most 4 When the mascara brush is pulled in and out of the mascara tube, too much movement will draw in too much air, which will not only bring in oxygen and accelerate the mold of the mascara, but also speed up the dehydration and drying of the mascara. |
