There was nothing to be disappointed about. Highly recommended. It's great to stock up during sales.

It's gentle on the skin and has a brightening effect. I'll be repurchasing.

5번 글루타치온C 비타수액 에센셜 토너

Instead of using a cotton pad (since it's not a watery formula), I applied it with my hands, let it absorb, and then layered on a bit more after a short while.

There weren't any downsides for me. However, I have a feeling it might not suit those with acne-prone skin.

The texture is like a runny nose, haha! It absorbs well and is great for dry, sensitive skin. These days, mainstream brands are so good that you wonder if you even need department store brands anymore. I highly recommend this product too.

I used it for nearly three weeks, but I didn't notice any visible effects. I don't plan to repurchase. It was disappointing considering the price point.

The texture and absorption are similar to other toners. I didn't experience any discomfort in that regard.

Won't be repurchasing
As someone who prefers watery toners that lock in hydration, I found the texture somewhat disappointing

Light yet moisturizing
Gentle on the skin
Recommended for dry skin

I wouldn't recommend this to those with extremely dry skin who need a bit of oil even in their toner. It has a slightly runny texture that looks very hydrating, but since it's an oil-free formula, the moisture does evaporate rather quickly.

This feels like an ampoule. I'd recommend it to those who find ampoules a bit heavy but feel that toners alone are too drying. 

I have a skin type where oil doesn't rise to the surface but solidifies inside. Due to sebum buildup, I often get blemishes, and even a slightly thicker skincare routine causes havoc. So I need hydration that doesn't evaporate overnight. Among toners, this product maintained moisture the longest. I could genuinely sleep with just this toner and wake up without my face feeling tight.

The No.5 serum was incredibly hydrating, so I expected this toner to be moisturizing too, given its viscosity. However, despite its runny texture, it felt more like a lightweight, alcohol-based toner, which left my skin feeling quite dry. While the ingredients list didn't raise any red flags for me, something about the combination or perhaps the drying effect threw off my skin's oil and moisture balance. With continued use, I developed what looked like hives. This reaction is typical for me when using products containing alcohol or those I find drying - whether skincare or makeup. It's a shame because the brightening effect was excellent, so I'm disappointed it didn't work for me. For those without extremely sensitive skin or a compromised skin barrier, this runny toner feels more like a refreshing serum without being slippery. Oily skin types might enjoy it year-round, while those with dry skin could find it suitable from late spring to early fall. The texture seems ideal for oily skin, but the viscosity might make those with oily skin hesitant to try it. It feels like Numbuzin might have missed the mark a bit with the consistency. If I were in charge of marketing this product for Numbuzin, I'd position it as a powerful brightening toner targeting oily skin types. It's a good product, but unfortunately not ideal for extremely dry skin.

As someone with extremely dry, sensitive skin, large pores in the T-zone, and thin skin, I'm a devoted fan of the No.5 serum. I've gone through multiple bottles, so I decided to try the toner for added synergy. Just like the serum, this toner's brightening effect is truly impressive. When I first used the No.5 serum, my skin immediately looked clearer, and the effect was so noticeable that even others could see the difference. Adding this toner to my routine made my complexion even more radiant. The first night I incorporated it, I was shocked by how luminous my skin looked in the mirror. Even my boyfriend commented, 'Why does your face look so much brighter today? Your skin seems fairer!' This confirmed the visible difference for me. It seems the No.5 line from Numbuzin works exceptionally well with my skin. Both the serum and toner gave me significant brightening results from the first use. The synergy between the No.5 serum and toner is definitely powerful.

There were no negatives. I liked it so much that I also bought the essence from the same line.

Second purchase. It provides long-lasting hydration, absorbs well into the skin, and feels comfortable to use. I was worried it might be irritating since it's a Vitamin C product, but it's gentler than expected and can be used without concern. The refreshing finish helps subsequent products absorb better. The scent isn't overpowering, making it suitable for daily use. With consistent application, I believe it will further brighten my complexion. I wonder if it's just my imagination, but my blemishes seem to have faded a bit?

The toner has a runny consistency, so I had to use it with a cotton pad, which I didn't particularly like. But worse, after using this, I developed small pimples all over my skin, so I stopped using it after just 2-3 tries. If you have super sensitive skin, I strongly recommend patch testing before use.

I bought this product during a sale event, but I really regret it. As soon as I used it, I got small blemishes. The ingredients seem a bit irritating for me, and overall, I don't think Numbuzin products suit my skin well.

I preferred using it with the absorption method rather than as a pack. I'm not sure if it's because of my cotton pads, but they didn't absorb and release the product well, so I used the absorption method! If you want to use it as a pack, I think it's best to just buy an actual sheet mask for maximum hydration!

There are no downsides! Absolutely none! Among all my brightening products, this one is truly gentle, incredibly hydrating, and I love it so, so, so, so much!

I tried the mask and loved it so much that I decided to buy the toner too!

Texture:
The consistency isn't exactly watery, but more like thin mucus? It doesn't run like water, but it's not sticky like mucus either!

Effects:
If you use this consistently, you can really see your skin becoming brighter! I used to feel that even 21 shade cushions were a bit light for my face, but now I don't think 21 is too bright at all!

Scent:
The fragrance is subtle but not particularly pleasant. It's not overpowering, but it's not a nice scent either.

What I loved most:
This toner is incredibly gentle and super hydrating! I've tried many brightening products, but most of them stung when they touched my blemishes. I always had to brace myself before applying them. But this one doesn't sting at all and is so gentle that it's perfect for daily use! And because it's effective, I find myself reaching for it again and again!

I recommend this for anyone who wants to incorporate brightening into their daily skincare routine!

- I'm not sure if it noticeably brightens the skin. If you're looking for dramatic results, you might need to pair it with a serum or cream.
- The snail mucin texture might be hit or miss for some, but I'm definitely a fan!
- Compared to thinner toners, it takes longer to absorb. You need to be careful when applying makeup over it to avoid pilling.

- Due to my job, I'm exposed to sunlight for long periods. This has left my skin dark, with freckles and hyperpigmentation being a concern. Please keep this in mind!

- Unlike watery toners, this one has a rich, viscous texture that keeps skin hydrated for hours.
- It seems perfect for fall and winter use. I love that it's neither too runny nor too sticky.
- I used just a small amount to prep my skin before masking, and it was absolutely fantastic!

Apply a generous amount of watery toner for hydration, then follow with a thin layer of this toner all over your face! I've been doing this for over three weeks now, and my skin has truly transformed. I'm deeply moved by the results!

I used to apply Numbuzin No.5 toner, then serum, and finish with cream. However, my skin type requires a watery toner, and without it, I experienced deep dryness and tightness. I consider this more of a functional toner rather than a hydrating one. To be honest, I didn't notice significant brightening effects. It seems like this toner is designed to be used with their No.5 serum. I'm using it solely for skin improvement, so I don't have any particular complaints!

Love it! My skincare routine ends with two layers of watery toner followed by the Numbuzin No.5 toner. Since it's slightly viscous, it leaves my skin with a beautiful glow. I wake up with noticeably improved skin! I've never experienced any blemishes from using it, so I'm really enjoying it. Plus, the price is quite reasonable!
