Using it together with tranexamic acid creates great synergy.

At first, before my skin adapted, it stung slightly, but after 3 days I adjusted perfectly and now I can use a full dropper without any issues!

It's a completely water-based formula that absorbs quickly, so I apply it first, even before toner.
Niacinamide is essential for brightening, and it's really helped fade my light sun spots!
I have combination dehydrated super sensitive skin, and while I experienced some initial purging, my skin has now adapted and I'm using it wonderfully!
My complexion has brightened by a shade, making this a staple in my routine.
The foundation shade I bought last year now looks too dark on me.
The texture is water-like and absorbs well - there's absolutely no stickiness or oily feeling.

닥터트럽 나이아텐 세럼

This product works hard to improve your skin's hydration and glow. It's great for those with combination dehydrated skin looking for a brightening moisturizer that evens skin tone without feeling sticky or causing pilling.

Switched to Skin Source 30 because of the price. However, if money weren't an issue, I'd still be using this.

Absorbs exceptionally well due to the absence of thickeners or glycerin. The texture feels refreshing and pleasant on the skin.
With daily use, you'll notice your complexion becoming brighter by the time you finish the bottle.

Since it's a water-based formula, I use it alongside other products when I need extra hydration.

It's great for daily light use. I'm using it both morning and evening after cleansing.

Try using it with Sidmool's Panthenol 30! Apply the Niacinamide 10 first, then follow with Panthenol 30.

When I think of niacinamide, I expect it to help control sebum. However, compared to other 10% products, I didn't particularly feel it drying out my oil. I'm not sure if it's due to differences in ingredients, but I actually felt a slight oiliness if I applied too much.

Texture: It's truly like water. Even more fluid than a water toner...? Perhaps that's why it absorbs so well. I've seen significant brightening effects. Scent: There's no smell. It's fragrance-free. Effects: It brightens, makes skin texture smooth, and has pore-minimizing effects. Great! At this price point, I think I'll keep purchasing it. Skin type: Combination dehydrated, oily.

With its generous amount and comfortable feel, there's nothing to complain about.

For combination dehydrated skin and acne-prone skin, the niacinamide and catechin blend helps soothe and improve skin texture without irritating pores. In my case, it seems to have a preventive effect on T-zone blemishes. It's rare for me to use up a functional ampoule, but this is my second bottle and I'm using it well. With its water-like texture, it absorbs quickly, making it suitable for use year-round without any issues. You might wonder if it's effective because it absorbs so fast, but with consistent application, it helps improve skin texture and complexion. It's a product where you notice the difference when you don't use it. If you're a fan of niacinamide, I recommend giving this a try.

After cleansing, as the first step in your routine, apply a few drops directly onto your face and let it absorb well.

There's nothing to complain about. It's a fantastic product that's both cost-effective and perfect for my skin.

I started using this product for my acne on a friend's recommendation, and wow! My skin has become incredibly smooth and soft. It's excellent for calming blemishes too! At such an affordable price, it's truly great value for money.

Rather than applying this alone morning and night, I found it more effective to focus on hydration during the day and only use this at night. I saw improvements in my skin texture, especially with those tiny bumps.

There's a misconception that Sidmool products are cheap, but compared to other products containing niacinamide from other brands, this one seems quite expensive.

After using this, I definitely noticed a reduction in sebum production and saw improvements in pore management! It seems to help with skin texture as well. I'm not sure about the brightening effects though.

✅ My application order: Toner > Vitamin C > Niacin > Finish with a hydrating moisturizer

None! There was no tingling sensation, and I didn't need any adjustment period.

After seeing a YouTube video recommending applying vitamin B3 after vitamin C for at-home skincare routines without visiting a dermatologist, I decided to purchase this product from Sidmool, known for their high-quality ingredients.

✅ Texture: The dropper dispenses the product in a fluid, drop-by-drop consistency.

✅ Absorption: It absorbs quickly with a light touch, without feeling like a heavy, ultra-nourishing ampoule.

⭐️ My thoughts after using it for about a month and a half: While my skin was already in good condition, it now feels even healthier. Despite the summer heat, my skin feels resilient and firm!

🍯 I bought two bottles with the 'buy one, get one' option on Sidmool's official website, which made it slightly more affordable.

I didn't notice any significant changes, but since it's a high concentration, it irritated areas with dermatitis, so I avoided applying it there. I've heard that this type of formula tends to have lower absorption, but I don't think it's ineffective.

Slight improvement in skin texture. Fragrance-free with a water-like consistency. Can be used just like a toner. A serum that lets you experience high-concentration niacinamide. Great value for money.

Occasionally causes small bumps on the T-zone, so I mainly use it on my cheeks. A small amount on the chin is fine. When used alone, it dries white and flakes, so always mix with other products

Great for restoring skin texture. Mix 3 drops of niacinamide with 2 pumps of centella toner or a small amount of EFI cream

I heard it was effective for brightening and sebum control, but I didn't notice any changes. It seemed to irritate my sensitive skin, causing blemishes and an increase in whiteheads.

The lightweight formula makes it easy to mix with other products without feeling heavy on the skin.
