For many, a concealer always has pride of place in their makeup bag, as it’s pretty much impossible to know when a spot or blemish might decide to strike, so it always pays to be prepared.
When you only use your concealer very occasionally though, it can last for a very long time, and it can be easy to think that it’s fine to continue to use it when there’s product left- even if it’s so old that you can’t remember where you bought it.
Continuing to use an old concealer is s major mistake though, as in addition to losing its efficiency, it’s also likely to be extremely unhygienic.
With time, many concealers tend to become thick and clumpy- and their consistency is no longer suitable for properly covering spots. In fact, it could actually attract attention to spots and blemishes.
An old concealer is also likely to be covered with bacteria- even more so if you apply the product directly to the skin without an applicator or makeup brush. It’s easy to see just how bad for the skin this can be.
Instead, invest in higher quality product which conceals and zaps spots simultaneously- such as Dermalogica Concealing Spot Treatment- and which won’t quickly turn clumpy like many stick concealers do.
