  Pros

  Absorbs well and feels great on the skin. It's a winner! Not sticky at all, so I usually apply it before bed.

  Cons

  While it absorbs quickly, it's almost too fast. When reapplying, it pills and leaves white residue like dead skin cells.

  Pros

  냄새없음. 물 같은 제형 가볍게 발리고 금방 흡수됨! 진짜 여름철에 사용해도 꿉꿉함&끈적임 1도 없어서 바르기 너무 좋음. 3번 정도 까지 발라봤는데 아무래도 나이마신이 공기와 닿으면 하얗게 변해서 그래서 그런가 피부가 뽀얗게 보이는 건 있어요.

  Cons

  뚜껑을 잃어버렸는데 사용할 때마다 입구에 남아있던 세럼(하얗게 굳어버린..)이 같이 나와서 손으로 걸러내고 발라야 되는게 좀 불편해요!

  Tip

  씻고 나와서 거즘 2달?간 바디로션에 2~3펌프 정도 짜서 착색 심한데 발라주는데 피부색이 균일해지는 거 같아요 조금씩!

  I love that it's fragrance-free, that's a big plus! It absorbs well without feeling sticky, and the application is smooth.

  Cons

  The only downside is I wish they'd have sales more often. It would be great if they increased the product size too!

  Pros

  Dermafactory Niacinamide 20% Serum Review Skin type: Oily + Redness + Combination dehydrated skin Usage period: About 2-3 weeks "I can definitely feel my skin texture improving." I was initially a bit worried about using such a highly concentrated niacinamide product, but I was pleasantly surprised by how gentle and comfortable it felt on my skin. The formula has a slight viscosity, but it absorbs quickly when applied, and the finish isn't sticky at all. It leaves a fresh feeling, making it suitable even for those with oily skin. What I loved most: - It seemed to reduce redness and blemishes - I noticed the sebum around my pores appeared more controlled Also, when I woke up in the morning, my overall complexion looked noticeably clearer, which made me think, "I should definitely keep using this." I was concerned about my combination dehydrated skin, but thanks to the hydrating rose water base, I could feel the moisture penetrating deep into my skin! The high concentration means quick results, and you can really feel your skin becoming more refined. I highly recommend this to anyone looking to improve their skin texture and even out their complexion!

  Cons

  While the hydration isn't bad, it feels slightly insufficient when used alone. On days when my skin felt particularly dry, I definitely needed to layer a cream on top.

  Tip

  For first-time users, I recommend starting with a small amount. Due to its high concentration, those with super sensitive skin might occasionally experience blemishes, from what I've heard.

  Pros

  Essential ingredients are the focus of this product, without unnecessary fragrances or artificial colors. Even sensitive skin can use it without worry. Consistent use has helped brighten my skin tone and reduce blemishes. The formula absorbs quickly without stickiness, so it can be used before morning makeup application without any burden.

  Cons

  I was very satisfied. The usability was good. There was nothing particularly lacking.

  Pros

  I've been using this for a month now, and I feel like my dark spots have lightened. The ingredients are great, and I'm really satisfied with it. Some might think the amount is small, but since I use it sparingly, I actually find the smaller quantity to be a plus. I love that I can use it during the day too. I have super sensitive skin, so I'm always cautious with functional skincare products as they often cause blisters on my face. But with this one, I'm using it without any blemishes at all. There's no stickiness, and I think this might become my holy grail product. The 20% concentration is great because you can actually see the results. I'm extremely satisfied, and this has become a skincare product I truly adore.

  Cons

  Personally, I don't have any real complaints about this product. Just keep in mind that since it's 20% concentration, you need to be careful with how much you apply.

  Tip

  I find that rather than using it alone, mixing it with my usual emulsion or cream allows me to use it gently without any blemishes at all.

  Great value for money, absorbs well without feeling sticky. It's perfect to mix with hyaluronic acid serum.

  Cons

  So far, I haven't found any downsides. I plan to keep repurchasing it.

  Tip

  Dermafactory daily holy grail combo: After cleansing, on bare skin: 1. Dermafactory B-Zero Toner 2. Mix of hyaluronic serum and niacinamide 3. Dermafactory B-Zero Cream For brightening days, add vitamin C to step 2 For firming, add retinol

  Pros

  DermaFactory's Niacinamide 20% Serum is a budget-friendly option with a high concentration of niacinamide that's been gaining popularity on social media and Naver beauty communities. After hearing about its effectiveness in improving complexion, controlling sebum, and managing pores, I decided to give it a try for nearly a month. The formula is lightweight and transparent, making it easy to apply. It absorbs well without any sticky feeling, making it suitable for summer use or those with oily skin. With a whopping 20% niacinamide content, you might feel a slight tingling or mild irritation when first applying. If you have super sensitive skin like me, it's best to start with small amounts and gradually increase as your skin adapts. In terms of results, I noticed my overall complexion becoming clearer after about a week or two, with blemishes and redness slightly fading. I also found that sebum production decreased, leaving my face feeling less oily in the morning. While pores didn't dramatically shrink, I noticed less buildup and my makeup applied more smoothly. Summary: Pros: High concentration (20%) niacinamide effectively improves skin tone, controls sebum, and manages blemishes and pores Cons: May cause irritation for sensitive/dry skin (tingling, dryness, dead skin cells) Texture: Light and fresh, absorbs quickly Recommended for: Oily/combination skin used to low-irritation products, those concerned with brightening, sebum, and pores Usage tip: Start with small amounts and gradually increase, recommended for evening use

  Cons

  The downside is that due to its high concentration, it may be irritating for dry or super sensitive skin, potentially causing tightness or slight flaking after application. In fact, many reviews on Naver and Google mention 'feeling irritation' and stress the importance of 'gradually adapting to the product'. However, there are also many reviews expressing satisfaction with the results, so I recommend adjusting usage based on your skin type.

  Pros

  This is one of the best value-for-money options among products with high niacinamide content! I follow a skincare routine of toner, emulsion, niacinamide serum, and cream. It absorbs well without feeling sticky or pilling. Since I switched from a 10% formula, I didn't experience much irritation. After using this, my skin feels more firm and elastic.

  Cons

  Perhaps due to its high concentration, sometimes crystallized residue forms around the bottle opening, which can cause irregular pumping occasionally.
