What the gurus are saying

The strong floral fragrance (geranium and citronellol) lingers and bothers several gurus, triggering headaches in some and itchiness from the essential oils in others. Those who don't mind fragrance find this nicely hydrating and brightening, with a pleasant texture. Anyone sensitive to fragrance may want to patch-test first. The pore-refinement claim didn't materialize, though reviewers noticed softening and a more even skin tone.

"For even cheaper you can get Numbuzin's number three skin softening serum, rather than a traditional essence this is like a slightly thicker serum with the added benefits of goat milk and squalane, nicely hydrating without being too thick."

"Ooh, the Numbuzin No.3 Skin Softening Serum. This is basically like a pore care serum designed to smooth uneven texture and refine the appearance of pores. We have a lot of fermented ingredients in here, kind of reminds you of like an old-style essence. Bifida ferment lysate and galactomyces ferment filtrate helps support the skin barrier, improve the texture, brightness. These kind of ingredients just make your skin look better overall. Niacinamide helps brighten and strengthen the skin barrier too, but we also have squalane in here for some very light hydration and adenosine too. They have reformulated this, I'm talking about the old one, but the new formulation has bakuchiol in it and they call it the bifida zero pore serum, pretty much doing the same thing but they focus more on improving uneven texture and discoloration as well. But I love the original and luckily I do have a refill of this. Like I said, it just reminds me of a traditional essence that I used to use all the time, SK-II, Missha, Secret Key, all those amazing iconic legacy brands, this reminds me of those. It just keeps your skin looking good, this should be an everyday use thing."

"This is going to be a turnoff for oily skin, it may not be my very first recommendation if you need really light skincare that doesn't offer any moisture, but I do think oily types still enjoy this serum. It's not going to be like you're using it in the first week and your hyperpigmentation looks better, [...] it's slow working. [...] When I'm thinking about all the brightening serums out there, [...] high percentages of niacinamide, tranexamic acid, arbutin, vitamin C, this wouldn't be my number one, right up there with the big guns. [...] But if you have very sensitive skin and you can't use arbutin or vitamin C or high percentages of niacinamide or tranexamic acid but you still need to work on discoloration and hyperpigmentation, I wouldn't hesitate to recommend this. The brightening is there, it just takes long for it to show itself. It's the type of serum where you're like, I don't know if this is working, you stop using it and you're like, oh, [...] my skin's starting to look dull again, the hyperpigmentation is really not fading at the rate it was before. Yeah, this serum definitely was working for me, I just didn't quite realize it at the time."

"This claims to target texture and dryness with forty two percent bifida ferment lysate, an ingredient where the research is still emerging but looks pretty promising for restoring your skin's barrier and helping with dryness, which is absolutely what I've experienced with that ingredient. It also has twenty one percent galactomyces ferment, plus niacinamide, hyaluronic acid, panthenol and some goat milk extract. I think it comes together for skin health, and especially the bifida and panthenol are wonderful for helping maintain skin health, I do think that is the strength of this product. All that said, at the end of the day I like the Manyo more, though I don't know if that's just because it uses more bifida, since we don't have enough research to know the effective percentages. This one is a bit more accessible though, so it's a great way to see how that ingredient works for your skin."
