4 Things to Consider before storing skincare in the fridge

#1 Water-based Products

If you are unsure what your skincare contains, then it is best not to store it in the fridge – unless directed by the product usage.

According to the lecturers of Diploma in Perfumery and Cosmetic Science at the School of Chemical and Life Sciences in Singapore Polytechnic, most water-based skincare can be stored in the refrigerator. These can include lotions, serums, toners and moisturisers.

It is worth noting that oil-based liquid skincare formulas might turn cloudy, so avoid storing skincare products like most face serums, which have both water and oil components.

Besides the temperature in the fridge can cause the water and oil elements to separate. When that happens, there is a chance that the formula would not return its original state, and thus, your skincare product is ruined.

#2 Cooler Doesn’t Mean Better
The stability and efficiency of skincare products are tested by cosmetic manufacturers according to climate conditions stated by the World Health Organisation.

This implies beauty products bought locally will be able to perform at their best in room temperature – unless otherwise stated.

#3 Product Freshness
A known fact to all is that refrigeration slows down the chemical and biological processes in fridge. Likewise, the process of storing skincare products at low temperature helps slow down bacteria growth and can prevent product degradation. However, this should not be confuse with refrigeration with preservation.

If you are using preservative-free skincare, refrigerating them can prevent bacteria from multiplying, it is unlikely the product will have a long shelf life, according to experts.

It is best to follow the expiry date printed on all cosmetic products, though ingredients like vitamin C could be better protected against oxidation in the fridge.

#4 Extended Shelf Life
Water-based skincare products can be chilled in the fridge at around 4 degree Celsius to extend the product life span, say the Perfumery and Cosmetic Science lecturers from Singapore Polytechnic.

Lastly, make sure they are properly label (to not be confused with food label) and keep out of reach from children.
