Pros
Here is the Hwahae Trial Reviewers' review: (Usage period: April 9 night - April 18 morning) ❣ Current skin condition Weak nose, blackheads, enlarged pores, freckles, and unexplained pimples on the temples Dry skin inside, and dry skin on the surface in spring, fall, and winter. Overall, the skin feels rough. (In seasons other than summer, when oil paper is placed on the face, it barely absorbs any oil.) +The face becomes parched without oil in winter ❣ Usage experience - no stickiness I think the usage experience is very important in warmer seasons. The lightweight formula does not feel sticky, which is good. However, if applied heavily, the finish has a slightly powdery feel, so if you want a moist or soft finish, you may need to adjust the amount or use another product in addition. ❣ Lacking both moisture and oil This is understandable as the product is not primarily for hydration. Applying it before makeup is not recommended due to the lack of moisture and oil. (This is not a shortcoming, as the function is not hydration. I'm just describing the characteristics.)
Cons
❣ Lack of sufficient usage period resulting in no effect Whitening is a battle against time, so it seems like you need to finish a whole bottle diligently to see the effects. ❣ Fragrance Too strong. It doesn't last long, but the rose scent hits you hard in the beginning. I wonder if there's even a need for a fragrance...? ❣ Glass container + price I'm not sure if there are effective ingredients that need to be in glass, but it's heavier than expected, and I thought it would fracture if I dropped it on my foot. Glass is not much more expensive than plastic, is it? If it can be changed to plastic, the price would go down and that would be great.

Pros
Spreadability. Spreads well without oiliness, stickiness, or slipperiness. Absorption is average, with a slightly lingering feel. Moisturizing is moderate. Does not clog pores but feels slightly heavy. The most important factors are skin tone and whitening. It seems to lighten, but the full effect is still unknown. I will use it up and write a review in two months.
Cons
The downside is that the fragrance does not last long, but it has a strong scent. It may be polarizing. The amount is less than the container size.
Tip
Use it only on areas that need freckle whitening and brightening.

Pros
I've been using the AESOI serum for a while now! This time, it's been renewed~ It contains PDRN, which is a trendy ingredient these days, so I think it's good! I'm not sure if my skin tone has brightened, but it has been effective enough in improving blemishes!! It's a lightweight type that's easy to apply~ It also absorbs quickly
Cons
I prefer unscented products, but the rose fragrance lingers, which is a bit disappointing.

Pros
The texture itself is a bit watery and moist. It's lighter than an essence but slightly thicker than a toner, with just the right in-between feel. When dispensed onto the hand, it flows like water, but when applied to the skin, it absorbs quickly. There's no stickiness or residue, and it doesn't interfere with makeup application - it sinks in smoothly and comfortably, making it easy to use morning and night. This type of formula would likely suit oily or combination skin types particularly well, but even dry skin types could use it comfortably alongside other moisturizing products without feeling any lack of hydration. For combination skin, it worked well as a daily option - lightweight yet sufficiently hydrating, not sticky in summer and layerable in winter. The effects aren't immediate in erasing blemishes or pigmentation, but it seems to work better once those concerns have somewhat subsided. It has a soothing, balancing effect on uneven skin texture or condition, so it's good for consistent use. Using this product, my skin felt comfortable and calm, and my makeup seemed to apply better. The benefits are more gradual than instant, but my skin became increasingly refined with regular use, handling sensitivity well. I'd recommend this as a lightweight, non-heavy basic for those looking for that type of formula.
Cons
The price range is slightly on the higher side, and the fragrance may be a bit divisive. It's not an artificial scent, but rather a natural rose fragrance with a hint of herbs. The fragrance is quite natural. It doesn't linger strongly for a long time, so I was fine with it, but I'd recommend testing it out if you're sensitive to fragrances.

Pros
No irritation My skin easily gets irritated depending on its condition, and if the product doesn't suit me, it immediately turns red and troubles arise. Even so, this serum was a product that I could apply comfortably regardless of the condition. It applies so comfortably without any irritation. That's why I reached for it more often than other products. Comfortable formulation It has a gel-like texture that doesn't flow like water. It applies cleanly without any residue. So I liked that I could apply it in the morning before makeup without any burden!
Cons
Other whitening and blemish-related effects will need to be tested further to know for sure. But even just the fact that it can be applied without irritation was already very pleasing to me. At first, there is a rose and herbal scent, but the fragrance does not linger strongly for long, which was fine. I was satisfied with the product!
Tip
This product can be applied morning and night with ease!

Pros
This is a clear, watery serum! It is not heavy, but light and does not feel oily, so I think it is a moisture-type serum. However, it is not too thin, so when I applied it to the back of my hand and turned it over, it did not flow or drip. Sometimes the too thin type of serum would quickly apply it to my face because I was worried it would fall off, but since it is not too thin, it was good. Completely satisfied! The photo is from two pumps, but one and a half pumps was enough to cover my entire face. For moisture supply, it is a bit dry, so I recommend using this serum to replenish moisture, then applying an emulsion or cream on top. Since it is a thin type, absorption is definitely faster. If you apply a lot, there is a sticky feeling left behind, but if you apply the right amount to your face, there is no sticky feeling and it finishes with a refreshing sensation. The part that I think will be the most polarizing is the scent! Personally, I think rose scent is the ultimate love-hate, and this product does have a rose scent. However, the rose scent disappears quickly after application, and it is not an overpowering or artificial rose scent, so even someone like me who dislikes rose scent was able to use it comfortably. *I'll add a bit more about the disappointing points!! I've been using it every day since I received it, and I definitely feel like my skin tone has improved! I think continuing to use it regularly will be even better.
Cons
I asked my friends to compare their likes and dislikes of fragrances a bit more, and a friend who dislikes rose scent even more than I do said they couldn't use it. They agreed that it dissipates quickly, but said the initial scent was too strong for them to use. In fact, since it's not a fragrance product, the scent itself isn't that strong, but since it's a disliked fragrance, it's unavoidable.
