Maybe this is already a well known fact to most of you but I only just discovered it and it’s made me a bit sad! The little jar symbol with a number in it on skincare and make up products tells you how many months it is good for after you open it. Often it’s a really short amount of time. I guess that teaches me to stop buying pricey skincare that I justify by not using as often so it lasts longer!

The moisturised lion does not care about the opinions of skincare product manufacturers.

If you aren't seeing any change in product color/texture, and also not seeing any negative effects from using it, it should be safe to keep using it.

Alternatively, get smaller bottles. I already do this since it is sooo much easier to travel with.

Fair enough. Each to their own I guess.

I guess it depends on what you care about. The time frames aren’t just arbitrary numbers that the manufacturers whacked on their packaging. Actives like hyalauronic acid and vitamin C break down over time. So your products could not really be doing what you are hoping for anymore. Additionally microbe introduction can lead to infection and you won’t necessarily be able to tell by looking at it.

If you have heard of Labmuffin’s Dr. Michelle Wong you will probably know that she is a great resource for science based information on skincare and beauty. Here is an interview with her about it.

Straight moisturisers are not something I will even pay attention to because I get through them so fast anyway. SPF is something I’ve always paid attention to the expiry dates for. I don’t want to mess with my eyes so I’m definitely going to be paying attention to those dates a bit more-application method will likely affect that.

The idea behind this PSA was for people like me who didn’t know how long each product was meant to be good for and wanted to know. As I said, maybe most people already knew this. I like knowing it because I was stretching out products with actives far too long that I should’ve just used up quicker.

I like the top on smaller bottles and will likely try that method on future. Thanks.

I know! You have to seriously slug it up as quickly as possible, huh? Won’t be buying that product again!
