Why you should never cut open your skincare products when they run out

We’ve all been in a situation where we can’t stand to part ways with our favourite skincare products, particularly if they are on the pricier end of the scale. That can sometimes see us going to rather extreme measures to use up the very last drop of our most-loved skincare, including cutting open tubes in order to scrape out remaining product.

However, the beauty experts at Allure have now revealed that this could in fact be a pretty terrible idea in terms of hygiene. Apparently, opening up products in this way can create an ideal environment for bacteria and the like, which can enter the formula and thrive.

‘By cutting tubes of beauty products, you are increasing the speed of oxidation and potentially exposing the spread of bacteria and fungus,’ Melissa Kanchanapoomi Levin, a dermatologist and founder of Entiere Dermatology in New York City, told the magazine.

‘Caution must be taken not to introduce microbes, since a large contamination may overwhelm the preservative system at some point and allow harmful bacteria or molds to grow in the product,’ added Charleston-based dermatologist Marguerite Germain. ‘Once the tube is cut open, the safeguards have been removed and the manufacturer can no longer guarantee the product.’

As well as introducing germs and bacteria, opening products in this way can be especially damaging for certain products such as vitamin C, which reacts differently to things like oxygen. ‘[It’s a] relatively unstable ingredient and tends to degrade and oxidize faster when exposed to air and light,’ Levin explained.

In the long term then, opening products can have far more of a damaging effect on your skin, even if it does save you a bit of money in the short term. Germs and bacteria can lead to inflammation and unwanted reactions, so it’s always better to be safe than sorry!
