It absorbs well into the skin and isn't irritating, so I think it'll be easy to use regularly.
ConsThere's not much to complain about, but the packaging was a bit inconvenient.
TipI think you'll get even better results if you apply a vitamin C serum first, then layer this product on top for added synergy.

It's a decent niacinamide ampoule. It was fairly usable. I didn't experience any noticeable irritation. The bottle design was user-friendly, which I appreciated.
ConsThere seemed to be a white powdery residue at the product opening. When applying even a few extra drops, a white powdery appearance was visible on the outer parts of the face, which was a bit off-putting. I wondered if the product hadn't dissolved properly or if its stability was somewhat compromised. My guess is it's niacinamide powder, and considering how nano-technology is trending these days for better absorption, this aspect was disappointing. Honestly, I think I preferred the other niacinamide ampoule from Isoi. It made me realize that a higher concentration of niacinamide doesn't necessarily mean better results. To be clear, the performance didn't meet expectations given the concentration, but the price and overall performance were still acceptable.

It's effective at controlling sebum production.
ConsThe free shipping threshold of over 30,000 won is a bit steep.

It's even better when applied right after cleansing.
ConsAfter using it for a few days, I noticed my skin feeling a bit dry, so I might need to add more hydration to my routine.

The value for money is great too!
ConsThere's nothing particularly disappointing about it. It can be a bit annoying that you need to apply it on damp skin to prevent pilling, but that's just a characteristic of niacinamide, not a flaw of this product.

ConsTo be honest, I'm not sure about its brightening effects. Even after two weeks of use, I've seen hardly any results.

I used the 10% version before without any major blemishes, so I bought the 20% one, and it's working out well.
ConsI prefer the dropper style from before. The current cap design is inconvenient to use.

ConsAbsolutely none!

I started with 10%, and since there was no irritation, I moved to 20%. It seems to suit me well, so I'll keep using only this!
ConsAfter applying, my skin becomes extremely dry. So it might be a bit harsh for winter use. Also, I wish they'd sell it in a larger size. It's smaller than expected and runs out quickly.
TipAfter applying and letting it absorb, make sure to follow up with a more hydrating cream! Otherwise, it can be too drying.

It was my first time using a niacinamide product, so I carefully studied the usage instructions on ISOI's website before trying it out. I've been applying it right after toner and before my gel moisturizer. Due to my sensitive skin, I started with just one drop and have been gradually increasing the amount. Fortunately, I haven't experienced any irritation, and I can feel my skin texture improving. Compared to when I first started, my skin definitely feels smoother. I'm being cautious and only using it at night for now. Since I have extremely dry skin, I've noticed it can be slightly drying, so I make sure to follow up with plenty of hydration. I'm satisfied with how it's refining my skin texture, so I plan to continue using it consistently while adjusting the amount as needed. Thank you to The Hwahae Testers for providing this great opportunity to try the product.
ConsI currently have a mild case of atopic dermatitis on a small area of my face. When I increased the amount (to about half the size of a dime), I experienced some irritation, so I've been avoiding applying it to that particular area.
