Pros

It worked well for blemishes and soothing my skin. The hydration level was decent, making it suitable for daily use.

Cons

There's nothing particularly disappointing, but it can cause a slight burning sensation when blemishes are severe.

Pros

The reasonable price for a high-concentration product makes it great for mixing and using in various ways. I recommend it for those who enjoy moisturizing formulas and niacinamide.

Cons

I've been using Paula's Choice 10% Niacinamide for several bottles now. Looking for a cheaper alternative, I found this product has similar effectiveness, but the texture is disappointing. The viscous formula leaves a slightly oily and sticky feeling.

Pros

It seems like a decent niacinamide product. The 20% concentration is quite high, so I'm mixing it with my moisturizer. I really wish they'd bring back the discontinued 10% niacinamide ampoule! If you look at the reviews for that product, everyone's asking for it to be relaunched.

Cons

The previous packaging was more convenient. With the current one, it's frustrating when you're running low because the dropper can't reach the remaining product.

Pros

You can definitely feel the niacinamide working. Some days my skin tingles a bit.

Cons

It leaves a white powdery residue. To be honest, I'm not really missing it when I don't use it.

Pros

I've been using this for several bottles now, and I love how it's evened out my complexion and brightened my skin. Personally, I feel like it's also helping with my pores somehow. Since it contains 20% niacinamide, I highly recommend doing a patch test before using it regularly.

Cons

You can get it cheaper on Coupang than on the official website. The official site is only more affordable when you have a sale coupon.

Tip

I don't use toner - I apply this serum right after cleansing my face.

Pros

1. It really does an excellent job controlling oil. When I apply it in the morning, my skin feels as matte as if I've used powder. 2. While using this product, I did see some improvement in my blemishes, though I'm not entirely sure if it's solely due to this product... 3. Given that it contains 20% niacinamide, if niacinamide is effective, this product should definitely work wonders.

Cons

1. There's a slight chemical scent, but it's not too off-putting. 2. When I finish my skincare routine with this, my skin feels itchy and a white residue appears... It's fine if I apply a moisturizer on top though. 3. It's quite frustrating that they set a high regular price and constantly sell it on sale. 4. As it's a high-concentration vitamin product, there might be some mild irritation.

Tip

It might be too concentrated for beginners. If you're specifically looking for a high-concentration niacinamide product, this is not a bad choice in terms of price-performance ratio among 20% products. It's frequently on sale on the official website and Coupang, so avoid paying full price.

Reviewed by The Hwahae Testers

Pros

The formula is colorless and odorless, flowing like water. It absorbs quickly when applied, but can cause a tingling sensation on bare skin due to its high niacin content. It works well layered over toner or serum. Rather than saying it brightens the complexion, it's more accurate to say it clarifies it. I could feel an improvement in skin texture after just one day. The blemish-induced pigmentation visibly fades with each passing day. I also appreciate that the bottle is brown, reducing the chance of light exposure.

Cons

There aren't really any downsides I can think of. If I had to mention something, the product can dry and flake off in a powder-like form if it gets on the bottle opening. I wipe the opening clean each time I use it.

Pros

It's convenient. The price and clean ingredient list are great. Niacinamide is the main active, supported by other beneficial ingredients. It seems to control sebum, though I'm not sure if it's reducing production or absorbing existing oil. Either way, it's effective for oil control. I'm looking forward to seeing pore-tightening effects. There's absolutely no irritation, which is fantastic. I love that it comes in a brown bottle. However, I haven't noticed any significant brightening or texture improvement yet.

Cons

I can't find any downsides, even if I try. This brand makes me curious to try their other products too.

Tip

If you don't control the amount, it can leave a white cast.

Pros

It brightens my complexion and effectively controls sebum. Blemish marks also fade quickly.

Cons

When applied alone, it can be a bit irritating and causes redness on my skin. I've been mixing it with my moisturizer instead.
