The review is completely unbiased and honest, with no guidelines or restrictions. Trial Reviewers' reviews undergo the same strict verification process as regular reviews, and if they don't meet our standards, revisions will be requested.ProsThe Derma Factory Niacinamide 20% Serum is an affordable serum with a high concentration of niacinamide, which has become a popular product on SNS and Naver beauty communities lately. I also purchased it after hearing about its effectiveness in improving skin tone, regulating sebum, and managing pores, and have been using it consistently for almost a month. The formula is thin and transparent, making it easy to apply without feeling burdened. It absorbs quickly and refreshingly without any stickiness, so it should be suitable for use even in the summer or by those with oily skin. Since the niacinamide content is as high as 20%, there was a slight tingling or light irritation when I first applied it. If you have sensitive skin like me, it's best to start with a small amount and gradually increase as your skin adapts. In terms of the effects, I started to notice that my overall skin tone became brighter and blemishes or redness were slightly faded after a week or two. Additionally, my sebum production decreased, and my face felt less oily when I woke up in the morning. While the pores themselves didn't dramatically shrink, I felt that the buildup of impurities within the pores was reduced, and my makeup didn't look as uneven. 🍀 Summary Pros: Effective in improving skin tone, regulating sebum, and managing blemishes and pores due to the high 20% niacinamide content Cons: May cause irritation (tingling, dryness, peeling) for sensitive/dry skin types Formula: Lightweight and refreshing, fast-absorbing Recommended for: Those with mild sensitivity, oily/combination skin, and concerns about whitening, sebum, and pores Usage tips: Start with a small amount and gradually increase, recommend using mainly in the evening
ConsThat said, the high-concentration serum may be irritating to dry and sensitive skin types, and the skin may feel taut or slightly flaky after application. Indeed, Naver and Google reviews often mention "feeling irritation" and "gradual adaptation being important." However, there are also many positive reviews citing satisfaction with the effects, so I would recommend adjusting the usage to suit your own skin type.

I'm using a routine of skin, lotion, niacinamide serum, and cream, and it absorbs well without any stickiness or heaviness, which I really like. I used to use 10%, and since I switched, I haven't experienced much irritation, and my skin feels a bit more firm and toned after using this.
ConsDue to the high concentration, the bottle opening sometimes has salt crystal-like formations, causing occasional strange pumping.

ConsThe effects don't seem to be that great. I feel like my pores are decreasing, but I'm not sure. This is the first time I've tried niacinamide, and I don't feel any special effects. I expected more since it's a high concentration.

Trial Reviewers' reviews undergo the same strict verification process as regular reviews, and if they don't meet our standards, revisions will be requested.ProsThis lightweight water-type formula absorbs smoothly without stickiness and is almost fragrance-free, allowing even those sensitive to scents to use it comfortably! ✔️As my skin is sensitive, I started by mixing a drop or two of this high-concentration product into my basic skincare, and after a 2-week adjustment period, I switched to using it alone. ❌ Since this product contains a high concentration of niacinamide, it may be irritating if used alone in the morning. It's best to mix it with other products or use a sunscreen when applying it in the morning.❌ ✔️ Changes after 4 weeks of use: - My dull skin tone visibly brightened and became more even. The redness was significantly reduced, making my skin look clearer. - Excessive oil production decreased, improving shine and extending makeup wear time. The frequency of breakouts also greatly diminished. ✔️ Overall: * The Derma Factory Niacinamide 20% Serum is highly recommended for those dealing with dull complexion, excessive oil, large pores, and frequent blemishes. * If you want to experience the benefits of a high-concentration niacinamide product at an affordable price, be sure to try this! I will definitely repurchase.
ConsThe design is somewhat inconvenient to open and close the lid, isn't it?

(ෆ`꒳´ෆ) Texture and application: The formula is lightweight and non-sticky. It glides on smoothly like water. When I tried to take a photo to show the texture, it flowed down like runny nose mucus, haha. Advantages: I have combination skin and significant pigmentation issues on my cheeks and around my mouth, resulting in uneven skin tone across my face. After using this product, I noticed my complexion became more uniform. Despite the high concentration of Niacinamide, the price is very affordable, making it an excellent value product.
ConsThe downside is that I usually dislike using very oily products, so I layered several light skincare products. However, after adding this ampoule to my skincare routine, my face felt a bit dry. As you can see in the photo, white crystals have gathered and clogged the opening. Even a little contact with oxygen causes this to happen... While it's manageable to remove the buildup around the opening, it sometimes appears on my face as well. It's like a scrubbing and leaving it feeling unfinished. If not for this, it would be perfect.
TipIt is recommended to start with a low concentration (less than 20%) product, as applying a high-concentration (20%) product from the beginning may cause irritation or redness. You can also apply about 2 pumps of the body lotion and mix it in, which you will visually see improvement in discoloration of the armpits or elbows! (In fact, I haven't tried it, but I was too shocked by the improvement in facial pigmentation.)

ConsNiacinamide containing 20 percent seems to be the reason why after using it, the liquid becomes runny and a white powdery substance forms, which can be slightly inconvenient.
