Part 2: The Big Cleaning of The Make-up Kit

The texture of the products and the ingredients that compose them also play a role in their shelf life. "Be wary of a mascara or liquid foundation more than a powder, for example. Oily or liquid cosmetics must be particularly vigilant, especially those you apply near your eyes, the most sensitive area of the face, "adds Dr. Roos. As soon as you notice a change in texture or odor, discard the product, even if it is not out of date. And whenever possible, opt for facial creams and foundations that are sold in pumped bottles, because these containers, which are more hygienic, are those that are less likely to become contaminated. "The air can not get in, so they keep longer." Finally, avoid trading products with your friends and remember that organic cosmetics are deteriorating faster than others. "They usually contain less effective preservatives than other products, and their shelf life is greatly shortened," says the dermatologist.

And if the idea of throwing your makeup gives you pimples, go for the powdered products, which preserve themselves longer, and buy small quantities. Above all, limit yourself to what you will really use! "Invest in products that you use all the time, like a good foundation, concealer or a quality powder. Choose a palette in beige-brown hues, which never go out of style. If for example, the trend is rosy this season, avoid buying a set of six eyeshadows that decline all shades of pink: go for one or two eyeshadows instead, and use them to background for a few months, "advises makeup artist Cindy Berthault.

How to maintain makeup brushes?

It is essential to clean the brushes regularly. Doing it every two weeks is a minimum, especially for people who use a foundation and liquid concealer. "You can use a shampoo, or a mixture of water and white vinegar. You have to soak your brushes for 20 minutes, then rinse well, "says dermatologist Nina Roos. As for the sponges, we can simply wash them with the machine with the dark linen, advises the makeup artist Cindy Berthault. "To get the most out of your products, it is essential to clean your brushes thoroughly. If you use a brush that has not been cleaned, you risk transferring sebum to your powder. And in the long run, the texture of the powder may be affected. "
