What was the biggest product disappointment you had?

This was so hyped several years ago, and might still be popular even now. Bought it because of the hype then and because of a certain YouTuber lol and well it's just okay to me. It feels nice and hydrating but did not help with brightening my dark scars/hyperpigmentation which is what it's supposed to help with. That's just me though, seems like it works fine for most others

I had high expectations and was pretty expensive. gave me breakouts

This pilled and made my skin sensitive/stingy. Too much niacinamide.

I was so excited about these eye patches but they are actually quite heavily fragranced and burned my under eye area

i am not sure about that
