Pros
Spreadability When using the serum, spreadability is also an important consideration, but it was absorbed quickly without any slipperiness or stickiness. Even when layering and applying, there was zero stickiness and zero heaviness, and it felt moist and refreshing. After application, the skin feels taut and firm. Moisture While the main focus of the product is blemish improvement, the moisture level was surprisingly good. As a dry-skinned person, it felt just right for my dry skin. Complexion This is truly an amazing product. I used to think my complexion looked dull every time I looked in the mirror, but after using it, I could feel my complexion becoming brighter, and those around me also commented that my skin and complexion looked better. Pigmentation My skin has severe pigmentation issues, but I've seen significant effects. Blemish marks are improving faster, and the uneven pigmentation is becoming more uniform. Skin Texture My skin used to be rough, uneven, and dull, but the texture has become smooth. There's a subtle inner glow as well. Comparing the before and after, the skin texture has improved a lot. Makeup Application Using this, my makeup applies well. With the improved skin texture, makeup naturally adheres better. The absorption is quick, so it doesn't cause the makeup to slip, and the moisture lasts without drying out over time. The adhesion also improves. It's truly an all-in-one serum - my skin makeup adheres perfectly. That's why I always use it before makeup. Sun Protection We all know how damaging UV rays can be to the skin. The Isoi blemish serum soothes and cares for sun-damaged skin, hindering the formation and movement of melanin pigmentation, helping with tone improvement and preventing blemishes from surfacing. It's a smart serum that not only improves but also prevents, plus it has antioxidant effects, so there's no reason not to buy it. Ingredients As someone with sensitive, acne-prone skin, I'm always worried about trying new products, but this has completed sensitive skin irritation testing and is suitable for acne-prone skin. It's also Excellent-rated by the German Dermatest and has vegan certification, so I can use it with confidence.Looking at the full ingredient list, it's easy to see why Isoi is so confident about their ingredients. The effects are stronger, but the irritation is 0.00 - it's just amazing. I haven't experienced any breakouts while using it. Fragrance While I generally prefer fragrance-free, the subtle rose scent is pleasant and not polarizing. Continued use seems to yield even better results, so I plan to keep using it for ongoing care. I'm so glad I found such a great product after a long search. I used to really struggle with blemish marks, but I'm so fortunate to have discovered Isoi. Thanks to the blemish serum, my skin has improved a lot, boosting my confidence. Better skin really does make a difference in one's appearance. I've tried many blemish-targeting serums, but this is the most satisfactory and effective one. Now I understand why it's so popular and well-reviewed - it truly deserves its top ranking. The range of benefits from just one bottle makes it a convenient all-in-one solution, which increases my satisfaction. Without exaggeration, this product is genuinely great, so I strongly recommend everyone to try it.
Cons
There were no disappointments about the product, but I wish I had used it sooner.. This is my only regret.

Pros
I have a troublesome oily skin type. 1. The fragrance is nice. I like rose scents, but this one is just a hair away from feeling artificial. It's not overbearing, and the fragrance doesn't linger for too long, which is good. 2. It applies smoothly and moisturizes well. It has a watery soothing gel-like texture. A single pump on each cheek is enough to use.
Cons
In fact, as everyone does, I had hoped for a dramatic user review, but it was not quite like that. However, as I have been using Hwahae and Noscara consistently, I can see that the discoloration is gradually fading.

Pros
Aiso products are using the cushion as the original product, and although I haven't used it much, the color and spreadability are good, so I'm sometimes looking around at other products, and I've also started using the Hwahae Trial Reviewers' brightening serum. The container is glass. It's designed to be used by pumping, which is good because it allows for clean usage. The color is not just pink, but a deep pink, which is my preference. The thing I like most about using it is the fragrance. I prefer unscented, but I like rose fragrance, so I was happy using it. Of course, it's a rose otto, but it's a bit lighter in fragrance than the 100% rose water toner I used before, as it contains purified water. The formula is a thin gel type, which is not my personal favorite, but it wasn't uncomfortable to use. And it's a colorless, clear gel. It has a clean, gel-like feel. The spreadability is gel-like, but it absorbs quickly and well, so it's good to layer the brightening serum itself, and other creams on top don't slide off and absorb well. I started using it the night I received the product, but I'm not sure if there are any noticeable whitening effects yet. I had been using a whitening product for about a month before this one. But as I was writing the review, I noticed that the faint discoloration I always had around my temples and cheekbones was no longer visible on the right side. I'm happy to see some effects from the whitening product again after a long time, but now I have to battle discoloration and wrinkles, so I'm both pleased and concerned. I haven't even used the brightening serum for two weeks, and I can see some effects, so I should diligently use it up to see the full results. I'd recommend this product if you have faint discoloration.
Cons
The disappointing aspect is the price. From the consumer's perspective, it would be ideal to find a good product at a reasonable price and in large quantities. While there is the pressure to use the product within 6 months of opening, if used daily, it would likely be consumed a month earlier.
Tip
The product is of a thin consistency and is readily absorbed, but it is better to apply it in small, overlapping layers. Please use within 6 months of opening.

Pros
Skin type: Oily/Excess sebum on the T-zone, including the forehead, in the summer/Slightly dry in the winter, with increased sebum due to dryness 💚Overall impression: A rose serum with a nice, bouncy finish ✏️Texture and application More hydrating than oily, with smooth and pleasant application When patted into the skin, it adheres nicely and has a bouncy finish, which is just my preference ✏️Fragrance The rose water scent is very prominent as soon as the product is applied This is a matter of personal preference and tolerance, and as someone who prefers unscented products, I find it a bit heavy Those who love rose fragrance will likely find it delightful ✏️Product performance Given the short one-week trial period as a tester, I haven't yet experienced any dramatic effects, especially for a brightening product like this. I think a longer observation period is necessary to properly evaluate the results If the effects turn out to be good, I'll come back and add more details
Cons
Ultimately, it seems to be the price aspect, doesn't it...? From the initial product launch, I've felt that the price-to-volume ratio is not particularly affordable, so whether I will repurchase it is something I'll have to observe further.

Pros
First of all, the fragrance is so lovely. I'm not usually a fan of rose scents, but it was surprisingly pleasant to smell. The application is also moisturizing and gets absorbed quickly. Even in a sensitive state, it doesn't feel irritating or uncomfortable at all. I was aware of its reputation, but using it in reality exceeded my satisfaction. It's been a while since I've encountered a serum that I'm so overall satisfied with!
Cons
I used 2-3 pumps every evening, and when I looked at the container, it seemed like I would run out soon, so I want to repurchase, but I think the purchase period will come back quickly.
Tip
There's no need to call it a tip, as applying a lot of it feels great on the skin.

Pros
The Aishoe Brightening Serum Skin type: T-zone - oily Cheeks - dry My skin is combination. Routine: I use it after toner. It's the only two products I use. Ingredients: The ingredients are really great! Fragrance: Rose scent Texture: Pump-type product Viscosity: Soothing gel-like texture Application: Applies smoothly and absorbs well with a hydrating feel. Adherence: Adheres and absorbs immediately upon application. Hydration and Sebum Balance: It has a slight tightness on its own. 85% hydration, 15% subtle oiliness. I've known about this product for a while, but haven't tried it yet. I've always passed on it because the price seemed high compared to the volume. I'm glad I have the chance to try it and write a review now. 1. The packaging is luxurious. The pink with subtle gold accents looks premium. 2. The fragrance is nice. Even the best skincare isn't good if the fragrance is unpleasant. 3. Excellent ingredients The ingredients are top-notch! Since I'm pregnant, I'm very careful about cosmetics, so I don't have to worry about this one.
Cons
1. Capacity? I need a slightly larger capacity. 2. It would be great if more came out with each pump.
Tip
I use a drop of jojoba oil at night. It locks in moisture and keeps my skin hydrated overnight.

Pros
✔️ Spreadability - The serum is thin and easy to apply smoothly! I was worried it might feel heavy since it contains oil, but it absorbs well without being sticky - just right. The fresh finish makes it seem suitable for wearing in the summer as well. ✔️ Ingredients, Sensitivity - There are a few noteworthy ingredients, but despite having skin that's prone to breakouts, I didn't experience any issues or new blemishes. It's not irritating, so it's good for daily use. ✔️ Fragrance - The fragrance seems to be divisive, but I personally enjoyed the sweet rose scent. I've heard the fragrance is stronger than before the reformulation, but since I haven't tried the previous version, I can't say for sure. In any case, I didn't find the scent to be overbearing.
Cons
The price seems a bit burdensome as the price-to-volume ratio is somewhat high. There is no particular feeling of blemishes fading or skin brightening.
Tip
Right now, in this weather, if you have oily skin, it would be perfect to do 2-3 steps of Hwahae + finish with a serum for your night care!

Pros
The Isoi serum was a product I used to use frequently, so I was even more delighted. The formula is slightly thinner, but it's not a runny formula that just flows right off. The application is good, it's not sticky, and it absorbs well. There's no sense of dryness, which is even better. One of the good things about using the Isoi serum is the fragrance - the subtle rose scent gives a feeling of being in a rose garden every time I use it. It's not an artificial or strong fragrance, so it's pleasant. After using it for about a week, it's difficult to see overall improvement effects. However, when I used it for a few months in the past, I did see my faint blemishes become lighter and my complexion look brighter, so I think with consistent use, I can expect to see the desired effects. The case also looks a bit more premium than before, so I'm looking forward to seeing Isoi's continued development.
Cons
There wasn't really anything disappointing, but I often used it up quickly. I had hoped they would increase the quantity, but a 70ml large-size product was released, and my dissatisfaction was completely resolved.
Tip
There's no tip..

Pros
****Hwahae Trial Reviewers' Review**** 1. Spreadability The Isoi Freckle Rose Serum seems to be a serum with a medium viscosity, not too runny but not too thick either. In my case, I like to apply my skincare products from thinner to thicker consistency, so I used the serum after the toner and water-based essence. It was quite moisturizing and absorbed into the skin quickly, and the spreadability was also very good! 2. Fragrance I had used the Isoi Rose Serum before, and the new one has a similar rose scent. It's not too strong, just a subtle, pleasant fragrance. I think most people would not have any issues with it. However, if you are sensitive to fragrances, I would recommend testing it out at a store like Olive Young before purchasing. 3. Efficacy This is the most important aspect! The Freckle Rose Serum is known for its whitening effects, and with the added Rose PDRN, it is said to be even more effective in brightening the skin. After using it for about 2 weeks, I didn't see dramatic changes, but I did notice my freckles becoming lighter. Overall, I felt that my skin tone was more even after using the product, so I think this serum would be a great choice for those looking to improve their skin tone. 4. Packaging The product comes in a cute, pink-colored pump bottle, which makes it very convenient to use. Just one pump dispenses the perfect amount to cover the entire face. The hygienic pump design is also a big plus!
Cons
The disappointing aspect seems to be the price, more or less. The product itself was overall very satisfactory, but the price is not exactly inexpensive, it seems. Haha
Tip
Since it is a serum with a medium viscosity, it would be best to use it after applying a water-type essence.
