It absorbs immediately and the feeling is just ~great. After giving birth, I couldn't take care of my skin, but the cost-effectiveness is really good and this product is just so good. For the first few days, there was a slight stinging sensation, but that's it.
ConsOver time, the lines all become coated in a white powdery substance on the lid.
TipWhen it's excessively dry, layer 2 to 3 times. Let it sit for a while.

I've been applying 1 pump in the morning and 2 pumps in the evening consistently, and my skin has become soft and smooth. It absorbs quickly, which is great.
ConsThe price is affordable, so I should use it liberally. But when I apply a lot, it leaves a white powdery residue.

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.

While I'm not entirely sure since I've only used it for a few days, I feel it's worth trying at least once. I saw results on my acne, and it doesn't cause my makeup to slide off when I apply it before doing my makeup.
ConsDry skin types may feel a bit dry after using this product. It's recommended to apply another ampoule or a moisturizing cream afterwards to help reduce the dryness.

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.

I used a 15% niacinamide product before, but when I tried this one, it wasn't overly irritating, and my skin felt more supple, which I really liked. It has a slightly tacky texture, but it absorbs well, so it should be suitable for all skin types except for extremely oily.
ConsIt would be great if it could be used as a dropper! The recommended usage is 1-2 pumps, so it needs to be applied in small amounts, but when I applied it to the back of my hand, it started to sting.

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.ProsI've been using it for more than 2 weeks. The texture and formulation are watery, so it absorbs well. It contains 20% niacinamide, so the ingredients are sufficient. I have oily skin, and when I apply this product, it feels moisturizing and has a certain degree of oiliness. I think this would be good for those with dry skin.
ConsI should have applied only one or two drops as explained, but since I used three or four drops, it seems like I'm developing skin troubles on my face. I didn't feel any stinging or irritation even when I applied a lot. I switched over from a famous niacinamide product, and since I have an oily skin type, the oiliness was a bit bothersome. I'm also wondering if there are any changes in pigmentation or complexion (this could just be my own perception). When I apply the moisture ampoule and then this product, if I don't apply a lotion here, it can also leave a whitish cast.
TipYou should use an appropriate amount.

After applying, it finished nicely and refreshingly. The price was also affordable, which I liked.
ConsThere are not many regrettable points, but it would be good if it was released in a slightly larger capacity.
TipApply vitamin C and niacinamide to help with whitening even more.
