That's really too bad! Yes it looks like it's oxidized. Vitamin C serums should be used as soon as you buy them and kept in the fridge to slow down oxidation.

It really is. I’ve used a few other serums and they didn’t oxidize before I was able to finish them. I’ve heard people complain a lot about this particular serum though, still sucks 🤦🏾♀️

I'm afraid it has oxidized 😔
I used the dear, Klairs serum before & here's how mine looked when it had oxidized ⬇️

Bummer. I already thought as much but it’s such a waste because I barely even used it🤦🏾♀️🤦🏾♀️
Little wonder they discontinued it, they should use a better protective bottle😬

You cannot keep your vitamin c.. if they have clear bottles.. in sunlight… they need to be in a dark dry cool area Or do what I do and put it in the fridge
