I use it once daily at night and the product always leaves my skin feeling soft, plump, hydrated, and with a dewy glow. It is non-greasy and non-comedogenic, therefore it's suitable even for combination and oily skin types. The smell is faint and not unpleasant.

Getting to the bottom of my bottle, and super sad they reformulated again. However, looking at Missha's website, it's still available alongside the new "moist" version, and I hope it stays that way. It comes in a glass component with a screw-on lid and a plastic stopper inside, just like the OG. The scent is practically non-existent and only hints at fermentation.
Was using this puppy as a toner at first, thinking its texture was too runny for an essence, but I definitely prefer it the other way around. In fact, it absorbs immediately, allowing me to layer it a few times, plus I see better results from all the amazing ingredients being packed on my face. It leaves no residue whatsoever and feels hydrating.
I honestly can not believe how concentrated this essence is while containing no irritating or clogging ingredients(butylene glycol is not that prominent). Niacinamide is high on the list and it shows - my complexion is brighter and more even overnight. I also really like the subtle addition of lactic acid, which helped with little bumps over time. On top of that, it combated whiteheads I had before using it, leaving my face breakout-free for a long while. Hyperpigmentation seemed to fade with time too.
It lasted me about 4 months of daily use and was one of the most effective products in my skincare artillery.
