What Does the Shelf Life of Skincare Products Really Mean

We all know that our food products expire, but did you know that your beauty products do, too?

It’s important to throw out all your old skincare, but I notice that a number of my clients don’t realise that their skincare goes bad.

If you have ever bought a product before and felt like it was going off, but are not quite sure what to do keep on reading, to learn about skincare shelf life, so you can “deep clean” your skincare routine.

Why you need to spring clean your products

Invisible bacteria can thrive in skincare products that are well past their prime, If you don’t throw away old products, they can easily become contaminated with bacteria and fungi and once applied to your skin, it can lead to a whole host of skin conditions including rashes, blemishes, and skin infections.

Preservatives are a very important part of the formulation

Preservatives help to keep your products fresh, yet there is a lot of controversy surrounding the use of preservatives. The reason they are included in your personal care products is to extend the shelf life and keep them fresh and safe from microbes, a subject we discuss in greater detail, in the article what are parabens.

The shelf life of your oils

Although oils don’t go off in the true sense of the word, they do have a tendency to go rancid over time.

You can always tell when oil has gone off just by the smell, for instance, Rose Hip Seed Oil formulas go off easily because the shelf life is very short. If you really like using Rosehip seed oil and want to extend the shelf life, a tip is to add Vitamin E to your oil at about 1%.

The shelf life of botanical butters

If you have purchased a body butter and it’s been sitting on your bathroom shelf for a while, you may be wondering if it’s still okay to use, the good news is that butters, and waxes don’t contain water, so bacteria has nowhere to flourish, so the shelf life is really long, keep an eye on them though as they do go rancid over long periods of time.

The naked truth

The shelf life of a product actually has a lot to do with the type of packaging the formula is sold in.  If the formula is in an airless bottle, this prevents re-contamination from fingers and prevents air from being drawn back into the bottle, meaning it is far less likely to become contaminated. Here at the Naked Chemist, we use an airless jar for our moisturisers and recommend decanting our balms with a spatula.

Unopened skincare products will obviously last longer than opened products, this is because they have less chance to be exposed to bacteria and microbes in general.

 Always throw away a product you notice has started to change color, or if it begins to separate, or changes consistency, or mold appears because this is a clear indication it is going off.
