## What does the expiration date mean? The expiration date is the date after which the product will not have the same effect. Of course, it's a shame to throw away any product that has not been used much. Every cosmetic product has two expiration dates. The first is for the unused product, and the second is for the one that has already been opened. After either of them is over, no one can guarantee the quality and safety of the product. Keep in mind that certain products, once past their expiration dates, can do more harm than good. > The older the cosmetics are and the longer they are used after the expiration date, the higher the risks. ## What are the possible consequences? - Expired cosmetics can begin to breed pathogenic microflora, which can lead to inflammatory processes. In addition, ===the use of any expired products may provoke allergic reactions of varying intensity from itching and stains on the skin to anaphylactic shock. And that's not all! - Mascara, eye shadow, and other eye makeup products can cause eye conditions such as blepharitis, conjunctivitis, and keratitis. - Powders, blushes, and eye shadows can provoke demodex, acne, and seborrheic dermatitis. - Face and body creams, serums, and foundations may clog the sebaceous ducts, resulting in acne and subcutaneous rashes. - Shower gels, shampoos, conditioners, and hair conditioners irritate the skin, causing itching, flaking, and dryness. > Mascara has one of the shortest shelf lives at only three to six months. And if stored improperly, open mascara can dry out even after a month. ## How to store cosmetics properly This largely depends on the lifespan of cosmetics and how quickly they will start to lose their properties. __Keep cosmetics in airtight containers with the lid closed__ when you are not using them. __Observe the temperature range of the product__. Each product has its temperature, but in general, cosmetics do not like high temperatures. Therefore, try to keep it away from light and high heat sources. __Cosmetics in tubes or bottles with dispensers are the best option for long-term storage.__
