Opinions on Tatchas Brightening serum??

Hey guys, I just wanted to get an honest opinion if any of you have used this serum. I am aware of its price which is why I wanted to know if it met its value, unfortunately I purchased it (it was a random buy) and wanted to get feedback before returning it.

I have used CEO Riley’s vitamin c in the past and have seen results but I think I became immune to its effect. I wanted clarity to see if it targets concerns such as dark spots/marks, hyperpigmentation and overall brightness EFFECTIVELY like other regular serums wouldnt.

Thank you!!
