No? Are you sure? If like me, you’re currently using a serum or facial oil rich in essential oils it might be time to give its packaging a closer look.
I was pretty sure my current facial oil was all clean and green… until recently when I smelled ‘burnt rubber’ while massaging it on my face. Eeek! For a while I thought that some of the ingredients had already gone rancid until I noticed something else. There were tiny black specks dripping from the base of the glass dropper. Apart from that, the opening rim of the bottle had a sticky dark-colored goo around it.
Then it dawned on me. The rubber bulb of the dropper had started melting!
Essential Oil and Rubber just don’t like each other.
There’s a good reason why essential oils don’t come in plastic packaging or why most should be diluted before use. Pure essential oils are so concentrated that they can dissolve rubber and soft plastic materials.
Because I brought my facial oil during my overseas travels recently, the oil had a lot of contact with the rubber part of the dropper for several hours during each flight. This actually happened to two of my oil-based serums before which both had lots of essential oils.
Noted. I should buy non-dropper mini glass vials for traveling.
If you’re using a facial oil or serum with a lot of essential oils in it and it comes in a packaging with plastic like having a glass dropper with rubber bulb, make sure to inspect it once in a while. Stare at it, sniff it. Check whether the packaging has contaminated the product. For frequent travelers, it really pays off to have travel-friendly vials with hard plastic cover/seal for your facial oils, serums and essential oils.
