Jars are BAAAAAAD, guys. I think that thanks to advertising, women associate cream in jars with luxury, or think a product is going to be super moisturizing/effective if it comes in one. Nope, nope, nope.
Most of the best skincare ingredients aren’t stable and shouldn’t be exposed to air or light. We all know antioxidants are great for the skin. Well, their enemy is listed in their name–oxygen! So let’s say you happen upon a moisturizer in a jar that is very well formulated. It’s going to rapidly get less and less effective every time you open it. Jars also harbor bacteria, since you repeatedly dip your fingers into them, and aside from that being kind of gross, it further breaks down the ingredients aside.
I personally avoid buying anything that comes in a jar. There are plenty of amazing products out there that are well packaged. And by the way, cosmetic chemists are well aware that jars aren’t the way to go, but cosmetic companies keep requesting them because consumers keep purchasing them. But anyway, let’s say you found a cream in a jar that you absolutely love. There is a way to save your product.
Get a set of airless pump containers like these and transfer your jarred products into them. If you can find opaque ones, even better. If you get these particular ones, store them in a medicine cabinet and try to keep them away from light. Obviously, it’s best to transfer your product when it’s brand new, since all of its beneficial ingredients will still be intact, but it’s still worth doing with a product that you’ve only had for a little while. Old jars should really just be tossed…and unless you are head over heels in love with the product, it’s best to search for something with smarter packaging.
