My skin type is combination, fluctuating between dry and oily. 1. Spreadability & Absorption The texture is not too watery when applied on the back of the hand. It spreads well and feels hydrating. After application, it has a slightly tacky finish. The absorption is good, and the moisture seems to quickly penetrate the skin. However, using it alone felt a bit lacking, so I layered it with a thinner ampoule first, then followed with a cream. This routine helped maintain a hydrated complexion the next morning. 2. Ingredients I'm glad it contains PDRN, which I prefer. I think using it long-term may help firm up the skin. Also, I didn't experience any irritation or redness after application. Aesoul is known for being mindful of ingredients, so I felt more assured using this product. It's marketed as a brightening ampoule that can help fade blemishes. While I didn't see dramatic changes in 2 weeks, I think continued use may yield results. 3. Fragrance The rose scent is pleasant to use. However, those sensitive to strong fragrances may find it bothersome. 4. Recommended Skin Types For oily skin, using this alone may be sufficient. For dry skin, pairing it with another ampoule would be ideal. I mixed it with an anti-aging ampoule and didn't find the combination too heavy.
ConsThe only downside, if I had to say, is that the bottle feels a bit heavy. But when used at home, it has a nice glass bottle feel to it.🤣
TipPersonally, I found the combination of Hwahae Ampoule and Hwahae Advanced Light Repair (in the thin brown bottle) to work well together.😊 The watery, fluid texture of the Hwahae Advanced Light Repair seemed to complement the combination nicely.

It's not an overpowering fragrance that stings the nose, but a subtle one that doesn't require much attention when applying. The formula is not water-based. When squeezed, it maintains its shape slightly without dripping, and spreads smoothly and easily when applied. It's a lightweight formula that absorbs quickly after a few pats. However, it may feel a bit taut after application, so it's not recommended for extremely dry skin. Normal to combination skin types can use it comfortably. There is little to no pilling when applying a moisturizer on top.
ConsThe brightening effect that helps reduce blemishes and brighten the complexion is minimal, even with 4 pumps applied morning and evening for a week. There is only a slight improvement in clarity. To see some effect, you'll need to apply at least 4 pumps generously for a month, but immediate results are unlikely. The moisturizing effect is quickly absorbed, but it doesn't feel like the skin is fully hydrated. When it dries completely, it's more like the surface has just been lightly dampened rather than the skin being replenished with moisture, so there may still be some tightness. The price is too expensive considering the volume and the effect. It's overpriced.
TipUse it generously and abundantly!

Putting anything on it causes skin irritation. I've suffered from seborrheic dermatitis before 😭 That's how sensitive my skin is. I'm also taking dermatological medication. 1. Formulation As you can see in the photo, it's a slightly transparent liquid formulation. It's not runny, but has enough viscosity to maintain its shape. To talk a bit more about the viscosity, I used the previous reformulated serum before, and it had a stickier, more viscous feel. But this reformulated product is different! It feels more refreshing. The application is also better than before, and there's no characteristic stickiness after application. So I liked that. 2. Fragrance? It has a rose scent. I think there will be likes and dislikes 😢 The fragrance is quite strong. It doesn't dissipate easily and lingers, so those with sensitive noses may find it irritating. But I'm not particularly sensitive to fragrances, so I used it without much trouble. 3. Efficacy? I applied it directly to my bare face consistently. Summarizing what I felt, first, the absorption was very fast. As soon as I rubbed it in, the product disappeared. Even when I layered it, it all absorbed quickly, which I liked. The previous reformulation had a bit of a rolling, slippery feel on the skin if I applied too much. But this one didn't have that, which was good. The fast absorption also seemed to mean faster effects. After about 7 uses, people told me my face looked brighter. Of course, the tone didn't change drastically, but there was a subtle difference. I think with more consistent use, the effects will become more apparent. There were brightening and dullness-improving effects. As for freckles and dark spots, hmm, those don't improve in the short term, so I'll have to wait and see. I'll keep using it consistently and come back for adjustments. Overall?Even as someone with sensitive skin, I didn't have any issues using it. I applied it quite generously on my face, and there were no problems. And my face looks brighter. So the efficacy was definitely there. The freckles and dark spots will need more time, but I'm satisfied with the results so far. The long-lasting hydration and the lack of stickiness were huge pluses for me. This reformulated serum is much better. I like it!
ConsThe price... right? The price seems too high compared to the quantity. That's why Hwahae is waiting for the Olive Young sale. Please hold events frequently. I beg you.
TipHwahae, applying the product twice is effective for dull and uneven skin around the eyes. First, pump out a small amount and gently massage it onto the forehead, nose, and cheeks. Then, apply it again thoroughly on the problem areas. Using a beauty device together with the product is also recommended.

The formula is very light and absorbs well. It's great for oily skin types. Among the products with PDRN, there are many with viscosity, but if you want something lightweight, this product would be good. However, it doesn't just flow down like water, and it's very easy to apply. In the winter, I often have dry cheeks, so I do multiple layers, but in weather like now, I finish my skincare with this serum, a hydrating serum, and an emulsion. If used consistently, you can feel like your complexion becomes brighter. Although I haven't noticed it much yet, as I've only been using it for a little over 2 weeks, when I apply the serum after washing my face, my face looks brighter than usual. It helps with blemish care. I tend to get hormonal pimples and inflammatory acne on my chin area, so I've been using acne patches, and the blemishes have healed faster than usual in the past week. My usual routine is a centella-based mist (optional), a rose serum, a hyaluronic acid serum, and a sebum-controlling emulsion. Even though I haven't been able to sleep much and have been active all week, I felt the blemishes fading, which I attribute to the changed product, the rose serum.
ConsThe price and the case are a bit of a concern. The glass container is very heavy, and I don't really like glass cases, so that's a bit disappointing. The price is also not that affordable, so I'm not sure if there's a specific reason why this design has to be maintained. The scent is also extremely strong. I've never tested this product before, and this is my first time using it, but the floral fragrance is about 3 times as intense as the Mamonde Rose Water, which caught me by surprise. Personally, I tend to get headaches when I smell rose, so my initial experience was 'Ugh!' But after continued use, I've gotten a bit more used to it. However, the scent is still very strongly perceived.
TipThe product seems suitable as a first step, as it is functional and applies lightly, blending seamlessly.

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.
ConsThere 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.
TipThere's no tip..

The subtle rose scent was just right, not too strong or too weak. These days, many basic cosmetics are fragrance-free, but this product's natural rose scent was wonderful. The absorption was incredibly fast. After a few pats, it was fully absorbed without any stickiness or oiliness, and I felt a lifting effect as it was absorbed. The moisture level was also good, so there was no tightness or dryness. After application, my skin looked brighter and my pores appeared tighter. Although this is a whitening serum, it also seems to have reduced oil secretion and improved my pores. After using it morning and evening for about 10 days, I could feel my skin brightening and the oil secretion decreasing, so my skin definitely improved. For oily, combination skin types that dislike excess oil, this seems like a really good product. In summary, it's a mattifying, pore-caring whitening serum with good moisture that doesn't leave the skin dry.
ConsThere were no disappointing aspects. The price seems a bit high, so I'll wait for a sale!

Even though I have sensitive skin, I've been using it without any trouble! It's a functional whitening product, but it's gentle enough for sensitive skin to use^_^ 💚 Moisturizing!: Just one application makes my skin incredibly moisturized~ The texture is a bouncy gel formula. It doesn't drip, so it's easy to use! 💚 A scent you'll want to keep sniffing!: Personally, I really love floral scents, and the Isoi serum's fragrance is just so good ㅠㅠ After applying, the scent lasts for hours and it's so soothing. It's not an artificial fragrance, but a natural rose-like scent. 💚 Whitening effect: After using it for about a week, I can feel my skin becoming brighter. I can see why the Blemish Serum is so famous. 💚 Absorption: It absorbs really quickly. It's great to use before makeup too~ My makeup doesn't slide around. 💚 Cute packaging: The pink and silver combination is so pretty☺️ Even the cap has nice detailing! I feel happy every time I look at the packaging!
ConsThere were no regrettable aspects. If I had to pick one, it would be the high price? I'll have to buy it during a sale!
TipApplying an extra layer to the areas concerned with blemishes makes those parts appear much brighter.

I'm the type whose T-zone gets oily just a little while after application. Among the products I've tried so far, I liked Tory and the serum the most, but now I think I'll be using the Isoi serum frequently as well!! There's a slight stickiness, but it absorbs completely and then it's fine! (My mom has dry skin and she said there's no stickiness when she used it) 🩷Blemishes Even though my skin is extremely sensitive due to menstruation, no blemishes appeared. As for the blemishes I already had, I used an ointment separately, so I can't say the serum alone was the reason...haha 🩷Other functions I've only been using it for about a week, so I'm not sure about the brightening or radiance effects, but I'm hoping the effects will show up with continued use!!
ConsI usually prefer unscented products, so I was missing the fragrance. I had imagined a subtle rose scent, but the fragrance was much stronger than I expected, which surprised me. The price seems a bit high to me. I was able to try it through the Hwahae Trial Reviewers program, but the price is a bit hesitant for my first purchase.
TipIf you have a skin type like mine with a lot of sebum coming up, I'd recommend applying it just once rather than layering it!! Since there's a slight stickiness, it might feel a bit heavy to layer and apply it.

First of all, I've only used it for about 4 days, so I can't really speak to the whitening effects yet. (If it's effective, I'll update the review later. These types of products seem to have a review period that's too short at just 1 week after receiving them...) The packaging is an airless pump, which is hygienic and nice. The formula is like a moisture gel, not too runny. The application is very smooth - it spreads out quickly and feels hydrating. It's a lightweight type that absorbs into the skin immediately, leaving almost no sticky or residual feel, just a refreshing sensation. As a oily-skinned person, I really like this feel, but it might feel too lightweight for very dry skin types. In fact, this product is not focused on deep hydration or nourishment, so using it alone as an essence step might not be enough. I'll likely layer it with other products. (For me, in the summer, this alone with a bit of moisturizer should be sufficient.) As everyone has mentioned, the rose fragrance is lovely and luxurious, providing a healing sensation upon application. And while the hydrating power is not strong, it leaves a smooth, glossy finish. The glow is not overpowering, so adding a bit of BB cream on top makes the skin look quite nice and healthy. Due to the pleasant feel and unique glow, I often reach for this as a serum before makeup in the mornings. The whitening effects are not yet noticeable, since I've only used it for a short time. I don't have major concerns with pigmentation or dark spots, but I'm hoping for an overall brightening effect, so I plan to use it consistently for at least a month. So far, after a few days of use, I'm quite satisfied. It doesn't irritate redness, and seems to be a relatively gentle whitening product compared to more potent ones.
ConsThere are no particularly disappointing aspects, and the main concern is that the remaining amount may not be easily visible.

However, it is not extremely runny either, you can think of it as a thin, watery serum. 📍Fragrance: Personally, I dislike fragranced cosmetics, but this serum has a natural rose scent. However, unlike many fragranced products, the scent is not artificial or headache-inducing. 📍Spreadability: Due to the thin texture, it absorbs well and leaves a non-sticky finish. 📍Skin type: For my sensitive skin, it did not cause any issues or irritation. I was a bit worried about the fragrance, but it was comfortable to use. This formula is suitable for all skin types. Dry skin types may need to use an additional moisturizing product as this can be drying. 📍Personally, I noticed an overall brightening effect on my entire face. I applied it all over, and my complexion appeared more radiant after using this product.
ConsThe price seems a bit high compared to the capacity. It gets used up quite quickly.
TipI recommend this serum to those looking for a simple, basic-level serum. Two of us used it together, and we both definitely saw brightening effects.
