ConsI have a really sensitive skin, so that's why there's a bit of redness and irritation that comes up sometimes.

The cost-effectiveness is simply outstanding!! Surprisingly, there was no irritation whatsoever on my skin. When using other niacinamide serums in the past, there was always a slight stinging sensation... The finish can range from feeling quite lightweight to slightly tacky, depending on the individual. For me, the lightweight feel was perfect!
ConsIt's not disappointing, but it's something to be careful about. I applied it alone without mixing it with other products, as I didn't feel any irritation on my skin at all, but my skin ended up peeling off! But I think it was because I used it together with the retinol cream. That was my own carelessness. 😱 You all should be careful!!

To use: First, I applied an aloe pack and then mixed it with the moisturizer I was using before! Recently, after drinking alcohol, a lot of small bumps and blemishes have been appearing on my skin, so I started using this product. In the beginning, it was very effective! But the more I used it, the more I felt it was having the opposite effect? To explain: Beginning: The effect was great Middle: Something doesn't seem to be quite right...? Ending: I should only use it when my skin is really bad! When I first started using it, my skin texture improved a lot and my blemishes faded, but the more I used it, the worse it seemed to get. I would recommend that people with a similar skin type to mine use it only about once a week, not daily.
ConsAt first it was good, but the more I used it, the more acne actually came up. ㅠ
TipApply the aloe pack and mix it with the moisturizer to enhance absorption. I recommend this.

ConsI'm not sure if this is the reason, but I'm having some trouble. ㅠㅠ

I did not experience any irritation on my face!! I use it occasionally when I feel like I need some pampering.
ConsThere are rumors that mixing this into body lotion makes it whiter, so I've been applying it to my body every day, but I've developed hives on my arms. Even if you use it, applying it daily is not recommended!!

I trusted it because the reviews on the Naver Market were good.
ConsI used this and got bumpy, eczema-like irritation on my neck. It was itchy and rough, and it spread widely, causing me a lot of trouble. Just in case, I stopped using it and tried it again, and it seems to be because of this. The niacinamide is in powder form, and I diluted it 20% in an ampoule, so I thought the effect would be good. But when I applied it, my skin became as dry as the Sahara desert on a dry winter day, and it was painfully tight. Even if I applied a moisturizing cream on top, this ampoule completely strips the oil from my skin, so I couldn't get any nourishment. My whole face felt like it was shrinking and pulling, so I'm worried about wrinkles. It's supposed to keep my skin moisturized, but with this, there's not even a hint of moisture. It's as dry as a piece of firewood. If I apply it to my body, I'll have to deal with eczema-like bumps. And just logically, if it sucks all the oil from an already oily face, applying it to my body would probably make me age faster, right? Those who say it has a whitening effect - that's not when you apply it, but the state of your face after washing it off. If you apply more than 2 pumps, you'll see what I mean. That whitening effect happens because the niacinamide powder makes the surface of the face look powdery and pale. But it washes off, and your original skin tone returns. It looks like you've powdered your face, but the pores disappear, which is just an illusion. Once you wash it off, it's the same as before. Fundamentally, your skin needs to stay moisturized, but this makes it so tight that even talking gives me grandma wrinkles. I used this with a cushion foundation that's supposed to be dewy, and a moisturizing cream, but my face still ended up cracked and matte. My routine is: cleanse, use a toner-soaked pad, then a serum with 1 drop of this + 1 drop of a vitamin ampoule, followed by a Centellian cream. But even the Centellian cream, which usually leaves my face glowy and well-oiled, couldn't prevent my skin from drying out. So how am I supposed to use this?
TipIn the summer, it may be usable when the skin gets oily. It can't be used in the remaining seasons. Cosmetics should be made to keep the skin healthy like cosmetics. What's the point of just throwing in niacinamide and making it like this? I looked for vitamin C instead of whitening, but it's better to use proper vitamin C even if it's more expensive. This kind of shoddy product is really rare these days.

It does not change dramatically, but rather restores the dull skin to its original state.
ConsAt first, I didn't know much, but after more than a week, the flushing became too severe, and my entire face, including my cheeks, forehead, nose, and chin, turned bright red. I also experienced itchiness and intense heat, and when I searched for side effects, everything matched up. I've given up on whitening and will focus solely on moisturizing.

(How polar-type am I? I even have blackheads on my cheeks, not just in the T-zone.) I bought niacinamide because it's said to be good for whitening, pore care, and sebum-moisture balance. The effects I expected from niacinamide were whitening and anti-inflammatory. When I first received it, I was worried because the niacinamide concentration was high, so I mixed it 1:1 with the Toridoll hyaluronic acid ampoule and used it. From then on, I gradually increased the amount, and now I apply the Toridoll ampoule and then the Derma Factory ampoule. After applying this ampoule, aside from the effects I expected, my sebum production decreased significantly! Now, if I don't use it, acne that didn't used to appear on my nose starts to show up. It controls the sebum so well, and the next day, my face, which used to be slippery, becomes a bit fluffy.
ConsOn the other hand, I did not see much effect in the whitening and anti-inflammatory properties that I had expected. The whitening effect seemed to have lightened the traces a bit, but I'm really not sure about the anti-inflammatory effect. In particular, I applied the ampoule to the back of my neck to try to get the whitening effect, but a lot of bumps appeared there. So I stopped using the body wash and just washed with water for a while, and it did get a bit better. Those with even a bit of dryness should be careful, as it might cause irritation.
