Should You Keep Lipsticks in the Fridge: Experiment Report

There has been a lot of debate on whether we should keep lipsticks in the fridge. Many say that the technique prevents them from expiring or getting rotten. The other group disagrees with this statement saying that there is no theory on whether cold temperature can make a lipstick long lasting. Do you wish to find out which side is right? If yes just go over my experiment report.

Preparation and Time:
The lipsticks I used in my experiment were L’Oreal Endless lip color (Color#730, Saucy Sangria) and CoverGirl Continuous Color (Color#040 Wineberry Sheer). I specifically picked them because I was not their fan and plus, they were cheap. I knew I was not going to regret if they ended up expiring. Another thing was that they were already half used by me.

Before locking them in the fridge, I put them inside a Ziploc bag so they would remain protected from the smell and accidental spill of foods and drinks. The lipsticks stayed inside for 2 years and one month.

Experiment Result:
I took them out yesterday. The smell test revealed nothing odd at all. In fact, their original scent seemed be still there. As for the colors, they did not change either.  There was also no problem with their gliding behavior. CoverGirl’s Continues Color is always glossy. Good news is that Wineberry Sheer, even after staying so long in the fridge seemed to not show any deterioration of that either. But the most surprising gist was the absence of bubbles. In the past, I heard from makeup experts that lipsticks taken out of the fridge gave off tiny water bubbles or sweat in the normal temperature of home environment. It is possible that their statement was based on those made in the 90s. I remember seeing the bubbles all over my aunt’s refrigerated lipsticks back in 1997. But now the formula in most lipsticks has gone through advancement.  Perhaps, that is why, the bubbles were not present in my lipsticks. Yet I wanted to do an artificial test to see if experts’ theory could still be taken as legitimate. So I allowed my lipsticks to stay 1 minute in front of the heater. See the result below.

Both the lipsticks seemed to still give off no sweat.  What we need to understand from this is that today’s lipsticks are very different. They do not become lazy in cold temperature. As a matter of fact, it is possible for them to survive at least 2 years in a row in the fridge. I left my lipsticks again in the fridge to see if they last even after 3 years. I will write about the result in 2013 around this time.
