Somehow it feels like a waste to throw away old cosmetics. However, if you keep it because it is a waste and use it only occasionally, it can actually be poisonous to your skin. [사진=게티이미지뱅크]Somehow it feels like a waste to throw away old cosmetics. Even if you don’t use the lipstick you bought one by one or the functional cosmetics you received as a gift a few years ago, you may feel proud if you display them on one side of your dressing table. However, if you keep it because it is a waste and use it only occasionally, it can actually be poisonous to your skin.
Cosmetics also have an expiration date. You may think it’s okay because you’ve only used it a few times, but cosmetics contain moisture and fat, so bacteria breed easily.
According to the Chungnam National University Agricultural Science Research Institute, 2 million bacteria were found in lip gloss that was expired or nearing its expiration date, and 1.4 million bacteria were found in lipstick. There were over 1 million bacteria in eye shadow. In particular, Staphylococcus aureus was detected in eye shadows and sponges used by hand.
Using lipstick incorrectly can cause skin inflammation… Even old shampoos make your hair dull.
Products applied to the lips are frequently exposed to air. Because we use it frequently while eating or working outside, bacteria are more likely to grow. It is best to use lipstick, lip gloss, tint, etc. within 6 months of purchase. If the product emits a sour smell or changes color, it should be discarded. If the liquid in the contents floats on top or the layers appear to separate, it should not be used. If you apply it directly to your lips, it may cause inflammation due to bacteria.
When using skin lotion, you should check the expiration date written on the outside of the cosmetic product. If the product has already been opened, it is best to use it within one year after opening. It is best to use products with highly concentrated nutrients, such as essence or functional cosmetics, within 6 months. As it ages, nutrients may be destroyed. Storage methods for products used every day, such as skin lotion, are also important. If you use it in a sunny place or on a warm floor, the product may deteriorate due to the influence of temperature or light. It is best to place it in a cool place without much sunlight.
It is also advisable to use shampoo within its expiration date. It is best to use unopened shampoo within 3 years of checking the manufacturing date, and unopened shampoo within 1 year.
According to WebMD, an American health information media, shampoo that has passed its expiration date may not function properly due to chemical changes. There are also research results that show that it actually makes hair dull. Some people sometimes use a little bit of leftover shampoo mixed with water. This can cause bacteria to multiply quickly and have a negative effect on the scalp and hair.
Preservatives in cosmetics lose their effectiveness over time. Natural cosmetics without preservatives have a shorter shelf life. To use cosmetics safely, it is best to write the expiration date and opening date on the container and use it within the expiration date.
