There are cosmetic products that we simply adore and find hard to part with, but sometimes they surprise us their shelf life. Can we extend the love affair with our favorite beauty products? What exactly happens to the products when they expire? Depending on their type and consistency, changes may be more or less pronounced and visible.
Products we usually use the longest time are foundations. Fluid and creamy consistency contains a number of ingredients which may separate in time. At the top of foundations there are often isolated oils in higher concentrations and those can clog pores resulting in bacterial growth. Avoid holding liquid foundation in extremely hot places, and be sure to throw away if you notice that it has changed its consistency or odor.
Mascara is also a product which you have to devote a lot of attention and closely monitor all changes. Closed can last up to two years, but they are still to be exchanged every three months. Mascara is applied to the lashes and those need to protect your eyes from harmful substances and particles, so mascara can be very quickly contaminated by everyday use. Keep track of how you use mascara on your lashes during the day and be on a look out for bad odor.
Eyeliner, liquid or gel form is going bad when you see a change in the consistency and smell. They can participate in the process of inflammation of the eyes, so avoid using it during inflammation because the bacteria can remain in the product and start the process of infection and inflammation one you get better.
The compact powders are grateful for easy and long-term use, so you can use them for several years. This particularly applies to blush and face powder that you use with brushes that are regularly washed. Bacteria does not thrive in dry conditions and even if it appears, you will notice it easily - powder will become tough and will cease to be pigmented. If you notice a specific layer on the surface of product, do not despair, it's just a cluster of oil that you can scratch off and continue the use. Finely milled powders and loose powder can last for several years and just do your best to use them with clean brushes.
Creamy blush can go bad quickly, so they need changing every 12 to 18 months. Unlike a cream blush in a pot, creamy blush stick is easier to maintain and lasts longer. If the product comes directly into contact with the skin, disinfect it with a cloth moistened with alcohol and allow to dry naturally.
Lipsticks would be good to change every year, which seems like a really short time. Cream products, often moisturizing and nourishing ingredients can dry out, cease to be pigmented or can be contaminated by bacteria from inflammatory processes. Avoid using lipstick when you have herpes or open sores. The same goes for gloss and liquid lipstick.
