Reddit mentions of Fantasea Spatulas (25 Per Pack) (Pack of 3)

I think this is difficult to answer because there's conflicting information everywhere.

Personally, I think it depends on what the product is, how quickly you use it and how you use it. For products that are light-sensitive such as Vitamin C serums, yea. I fully believe that jar packaging renders it ineffective. It's also why people do their best to keep OST C20/21 in the box, in the fridge etc. For me, I'll usually decant products such as these into airless or opaque packaging or simply choose something like Drunk Elephant C-Firma Vitamin C Serum which comes in an opaque vacuum pump.

However, for regular products such as moisturizers, I've given up on avoiding them just because of jar packaging because I use a clean spatula each time I dip into a product (also cuz I have long nails and getting it under my nails is gross) and I go through cream pretty quickly.

Here's my spatula setup. I actually purchased a bunch of little spatulas from Amazon and keep the clean ones in a small jar from IKEA and toss the used ones in a small shot glass. Then wash and repeat. I think I use at least 5 spatulas a day!

Here is one I found on Amazon.
