What the gurus are saying

This serum earns consistent praise for visible plumping and brightening that shows up quickly, with gurus noting it refines texture and evens skin tone. The catch is texture: it's noticeably thick and creamy, leaning sticky rather than silky, which means those with oily or warm-weather skin may find it too heavy, though it works beautifully for drier types. One note: it can pill under certain sunscreens in the morning, so those wanting to layer it may prefer saving it for evening.

"The Neogen Real Ferment Micro Serum, it's 30 bucks. It contains Bifida, Saccharomyces, rice ferment, and Aspergillus ferment. No scent in it. I've repurchased. I think this is my fourth bottle of it. It's really nice. Serummy texture to it, really good for plumping up skin and lots of good ingredients in it. So I really love this one from Neogen and I've been repurchasing this one for a long time, so years."

"The Neogen Real Ferment Micro Serum has got the Buida ferment, sodium hyaluronic, the glycerin and the vitamin E and it's really nice. This is another product I've repurchased multiple times and it's really lovely and it's got all those as well as a ton of other good ingredients so it's a really nice repairing serum."

"The Neogen Real Ferment Micro Serum is another great plumping one. It's got kind of a goopy texture to it. [...] It contains a lot of good ingredients, no scent in it, and it instantly gives skin a plumped appearance without looking or feeling tacky, sticky, or greasy. [...] This stuff's really nice.

Best Affordable K-Beauty Facial Serums for Anti-Aging & Antioxidant Protection
"This is currently the most expensive one on the list, and it's one I've repurchased several times. I think this is probably my fourth bottle. This stuff is wonderful. It's got a little bit of a thicker, kind of a lotion-y serum to it, but it's super nice and super hydrating. It's got baida and saki, which are great for brightening your skin and protecting it, plus [centella], resveratrol, which is a great antioxidant, sorbic acid, and glutathione, which is known to be a good brightening ingredient. They have a lineup in this, but be careful with the other ones: they have a toner in this lineup which is fragranced, but there's also an essence in this lineup which is not fragranced, and it's easy to get them confused."
My Holy Grail Serums Over the Past Ten Years ♪♪ For All The Serums I've Loved Before ♪♪
"The Neogen Real Ferment Micro Serum is amazing. It's got so many good ingredients in here, it's still got the good antioxidants, it's got the peptides in here, it's got the ferment in here. It's good especially for the price, it's just full of good stuff. It's definitely a little bit thicker than some of the other products, but this one is really nice. I repurchased, I think this is probably my third bottle or so. I found sometimes it makes it pill a bit under certain sunscreens, but I really like using it in my evening routine now."

"I noticed when I was using this that it seemed like I just wasn't struggling with that as much, and not every review that I read on this product mentioned that, but a lot of people said that it really did seem to help with texture and with pores. [...] With fermented ingredients you can often see a refinement with your skin, especially when you're using high quality ones or a good quantity of them."

Ranking Summer Skincare Empties! 🌟🌟🌟🌟🌟
"This is a serum that contains some galactomyces ferment, I believe there's also bifida ferment in here, lots of different ferments as well as a little kiss of ascorbic acid. I actually like the serum quite a bit. It's a little bit more of a streamlined and focused ingredients list in my opinion, and I really liked the benefits that I saw with this. This is quite brightening, it really evens out the skin tone, brings out that healthy lit from within glow, which is what I expect from galactomyces, but the serum delivers and delivers pretty fast. The only thing I don't love about this is the texture. It is so thick, it's a really thick cream texture, and it's not like a silky cream texture, it's like kind of a heavy, slightly sticky cream texture. It's not going to work for a lot of skin types, and quite honestly it was a little heavy for me personally. As we move further into the warmer months it was just too heavy. Really great performing fermented serum for the right skin type."

"The Neogen Real Ferment Micro Serum includes an ingredient called bifida ferment lysate, utilizing the benefits of fermented lysates in a nice serum consistency that's very nourishing. I recommend this for people who have drier skin since it has a thicker consistency compared to more lightweight serums. I've used this one in the past overnight, it's a really popular Korean skincare product that utilizes the benefits I've talked about in this video."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Source: DermNet

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
