Okay, so good! But then I have a hard time understanding how one can think that it is unhygienic... a regular pipette is significantly worse (or a jar..) - especially when many touch/pull the pipette over the skin when they apply their serum. Perfect way to introduce bacteria into the bottle.. I think this should actually be pointed out since it seems to be more of a rule than an exception that people do this 🤔
So yeah.. I really have a hard time seeing how a pump bottle spreads bacteria, plus it preserves the product itself since you don't open the bottle 👍
