I like this serum, it's lightweight, soothing and hydrating on my skin. It feels very similar to an HA serum but it's also soothing and moisturizing without being sticky. I like how well it sinks in and leaves a soft glow but nothing too dewy that look greasy. I haven't noticed it reducing my oil production but that might take more time. It layers well under my other products without pilling and it's so more affordable than a more expensive standalone HA serum I was currently using. My skin just feels plush and comfortable. I think this would be best for those that just and a gentle serum to maintain balance and keep skin looking healthy without a lot of fluff.

I like that there's a seal on the box to let you know that it hasn't been opened. I also appreciate the clear expiration date. There is a little cap over the pump. I think it's meant to keep it from accidently getting pressed during transit and spilling or leaking product. I'm going to keep it since it will be great for traveling with this bottle. I also think it's interesting that this product has a little drug fact label which Korean skincare doesn't normally have. I wonder if it was created with an American audience in mind or if this is a new company-wide change that is happening.I had no issues with this serum. It did its job of providing lightweight hydration. I didn't notice much in terms of controlling excess oil or preventing breakouts. My skin didn't experience any irritation or breakouts while I've been using it so I can't say much about its soothing abilities. I like the numbuzin brand overall and find their products to deliver on most of their claims.

Every once in a while, my skin turns into an oil-slick in the summer. Most serums become too heavy in the subtropical climate I live in during summertime and that's where this serum from Numbuzin comes in! It's lightweight heaven! The formula is non-sticky, and non-greasy, and features oil-controlling ingredients that soothe and plump so the angry skin goes away.This is formulated specially for sensitive skin so my skin didn't have any issues when using it. I couldn't detect any scent through my smell test or by scanning the ingredients so this might even be food for those sensitive to smells in their skincare. I'd say this is great for all skin types despite being promoted towards oily skin because of how soothing and gentle it is while fighting excessive oil. :) I think I'll be reaching for this again next summer because of how good it was and because it's a phenomenal formulation for the current price of under $15.
