The verdict

Buyers' weakest aspect—fragrance (2.5/5)—directly overlaps the critic block noting the product's unpleasant smell, which reviewers acknowledge but tolerate for results.
In their words
“The hunt for a good vitamin c is a battle I’m sure we’re all familiar with. I have tried Tatcha’s previous vitamin c which broke me out, alongside YTTP (no results), and Drunk Elephant (both formulas, one felt gross and sticky and one didn’t yield results). I have to say after trying Tatcha’s reformulated vitamin c, it is the only one I have seen real results with. I have noticed some of my scars ”

“I love Tatcha but a lot of the their products are overpriced including this one. It's not a bad product at all but I think there are better vitamin C products for less. The biggest disappointing thing about this serum is the fact that it looks like you're getting a lot of product but you're not, it comes apart and it's a smaller bottle than advertised. Can someone please explain that to me? I don'”
