Love this Vitamin C serum with Kojic and Ferulic acids.
This is a Vitamin C serum with Ferulic Acid, Vitamin E and Kojic Acid. I like the viscosity of the serum it is an opaque white thicker liquid that does not drip out of the eye dropper like water. Yet it is lightweight and spreads evenly, quickly absorbs and brightens your skin. It does not burn or irritate my skin. I do have to use a moisturizer after. There is a faint citrus acid smell to this but it quickly dissappears after applying it. This is a quality serum that really works to fade the brown spots and even out my skin tone. I love the results.

No issues with my extremely sensitive skin
UPDATE: I have been using this serum for about 6 weeks now, and strangers have been walking up to me and asking me what I am using. Seriously! This has happened to me three times this week, and I barely wear any makeup at all. I’m almost 53. Even my friend’s 26 year old daughter asked me what I was doing because my skin was beautiful and glowing. I have never had strangers stopping and asking me about my skin before, and I can only attribute it to this serum. I don’t wear foundation, and only powder my face lightly, and I also wear mascara and use an eyebrow pencil to fill in, but that’s it. I recommend this serum, and I am absolutely going to keep using it. Even I can see the change in my skin over the last several weeks. This serum feels great, soaks in quickly, and I have strangers walking up to me asking me what I am using. Wow.ORIGINAL REVIEW: I have extremely sensitive skin. It all started with a trip to Mexico in 2010. I got sick, and at the same time, all of a sudden, everything I used on my face started giving me rashes and hives. Like every single thing that I tried on my face. This continued through early 2025 when I finally visited a dermatologist.I learned that, apparently, there can be an incident that sets off the body to have a response and treat everything like it’s under attack.I am 52, so I haven’t been able to use anything on my face, including any anti-aging lotions or serums since I was 38. Sigh. He did recommend a product line that miraculously worked with no issues or irritation. Since then, I’ve gotten bold now and again and tried a new product. Most of the time, after a few days, I start to feel the itch and know that if I don’t stop using it, there is going to be an issue.I was curious about this serum because the dermatologist told me that the absolute best thing for anti-aging is vitamin C. The ingredients all look to be straightforward, so I decided to try it, with fingers crossed!I’ve been using this serum for 5 days in the morning and night, and I have no reaction! The ingredients are clearly pure and good. I like the way this feels on my face. It has a light citrus scent, and it soaks in quickly. I have been using 4-5 pumps to completely cover my face and my neck.I like this enough to say that I will continue to use this and buy it after I finish this bottle. My skin feels so soft, and it looks smooth and beautiful. Will it minimize any wrinkles that are starting to show? I don’t know, but I love the way that it soaks in and how smooth my face feels, and no allergic reaction!

No noticeable effect for me
I’m just not good at skin care in general so I know that part of this is on me for not having a good “routine” that I can add this too and know perfectly well how my skin should react or whatever. But for more than $1/ml (do you know how SMALL a ml is?? and look, I got a big face!!) I just wasn’t impressed.I didn’t notice any particular smell, and I didn’t have any bad reactions – but I didn’t have any particularly good response, or in fact any real noticeable response at all. I would probably need about a bottle a week of this if I were to use it regularly, and at the listed price I’d honestly rather just save that money and get a professional treatment once a month or so.I bet my fingertips will never have wrinkles, no matter how old I get, though.Full product name: IKI Nihon Antioxidant Kojic Acid Serum – Kojic Acid + Ferulic Acid & Vitamin E and Vitamin C Serum for Face – Brightens, Evens Tone & Protects – Clean, Fragrance-Free, Cruelty-Free – 30ml

Lightweight
I have hyperpigmentation from decades of acne. It did not break me out, but i didn’t see a noticeable difference in my acne marks. It was gentle and moisturizing, unfortunately it didn’t do much for me.

Gritty/gummy clumped serum
Unfortunately, this serum arrived clumpy and gritty, which made it difficult to apply. It doesn’t smooth onto the skin well at all, and the texture feels off compared to what a serum should be. Because of this, it was hard to use consistently. Very disappointing experience overall. Hopefully this was just a bad bottle that I received

10/10 recommend
The glow factor of this antioxidant serum is shocking. I am frequently complimented on my dewy skin. It has definitely made a difference in my tone and the brightness of my skin. It’s overall improved my complexion, evening out my tone while also nourishing it with hydration. I have sensitive skin and this did not bother my whatsoever. It’s lightweight and a thin serum, easily absorbable and doesn’t leave my skin sticky. It is on the pricier side for the size, but the quality and value is evident behind the price tag.

Good product, bad price point
This is now my second product that I have used from this beauty line. I will start by stating the the serum is good, however, is definitely overpriced and the marketing is confusing. The brand markets itself as” inspired by Japanese Beauty rituals’ but is made in America and the name and logo is associated with a Colombian Medi Spa.My first concern is that the product listing does not have a full ingredients list. At this price point and something being marketed as a luxury brand with, gentle, natural Japanese beauty standards the full ingredients should absolutely be listed. It does seem safe for sensitive skin however the lack of fragrance in this case means that there is a slight chemical, medicinal smell. I would prefer a safe hypoallergenic scent to cover this. The ingredients are solid and the results are plumper, brighter, softer skin without feeling greasy or sticky or triggering my combination skin to either dryness or an oil slick. However I can get the same results with other quality brands at a third of the price.I do think the folks behind this line have solid products and are clearly trying to build a brand. Adjusting the marketing and the price point, however seems necessary before this product will get the sales it deserves.
