Pros
Here is a review of the product after using it as a Hwahae Trial Reviewer. I used it morning and evening after cleansing for a week. * Rated 5 out of 5 stars. Skin texture: ★★★ The galactomyces ingredient worked well for me. I've used the Missha Cynic range extensively before, but this is the first time I've used a serum. It doesn't leave residue on the cotton pad and applies directly to the skin, so it's convenient and my skin texture is definitely improved. It's a shame it didn't show up in the photo. Improvement of dead skin: ★★★★ It's winter and dry, so it was good at calming the dead skin on my cheeks and nose. Even when just wearing sunscreen, my nose bridge was peeling, but after using the serum, it's better. It seems the panthenol ingredient agrees with me, as I didn't get any breakouts. Texture and application: ★★★ As a serum, it has a slight viscosity. I quickly dispense a drop on my forehead, nose, cheeks, and chin, then spread it with my palms. It absorbs quickly, so I can apply my moisturizer right after.
Cons
The Hwahae has a slightly milky or musty smell when first applied, but the odor disappears after application. This is normal, so you'll have to endure it. The dryness is quite severe, especially in the winter. Even after applying a serum, moisturizer, and an oil-based lotion, followed by sunscreen, my face still feels tight and drier than just using a toner. I'm not sure if it's due to the whitening ingredients or the wrinkle improvement properties, but I'll continue using it and provide additional feedback.
Tip
Sunscreen should be applied as the whitening ingredients are present. First, test the sensitivity on the neck and chin, then apply it to the face. For wrinkle improvement, extend the application to the neck as well! After applying to the face, use the remaining product on the elbows too.

Pros
Hwahae Trial Reviewers' review ✔Skin type My skin is very dry and oily, with large pores in the T-zone. ✔Packaging: The dropper-style packaging is hygienic and allows me to control the amount of product I use, which is great. ✔Texture: The watery, thin formula absorbs into the skin immediately. There is no residue or oily feeling left behind. ✔Exfoliation: After using the product for about a week, my skin felt much smoother. While the dead skin is not visible in photos, I can definitely feel the improved skin texture when I wash my face. ✔Low irritation: I usually find exfoliating products to be irritating, but this one did not cause any stinging or discomfort when I used it morning and night as part of my skincare routine.
Cons
The fragrance is not particularly pleasant. It's not odorless, but has a distinct musty aroma, which is not personally my preference, so I was a bit disappointed. The product is contained in a glass bottle, so it is a bit heavy to carry around for travel. I'm not sure if it is effective for whitening.
Tip
Personally, applying the corresponding product before the skincare routine and then using a moisturizer resulted in exfoliation and hydration, leaving my skin feeling more moisturized!!

Pros
My skin type is combination + sensitive. First, the packaging was so neat and pretty, and I could see how much product was left, which was great! The fact that galactomyces ferment filtrate is the first ingredient on the list means it takes up a large portion, and I was satisfied with that. The *pha ingredient also allowed for gentle exfoliation, which was nice. I thought it would be sticky, but it was less so than expected, and the hyaluronic acid made it feel moisturizing when applied. I thought the product would evaporate quickly, but it absorbed into my skin and lasted for a while. At first, I only used it in the evenings, just in case, since I have sensitive skin. But there were no issues, and my skin was fine. Since the ingredients are all gentle, I think I'll continue using it happily. My skin tone also seems brighter.
Cons
There wasn't really anything that I was dissatisfied with while using it~!! The only thing I'm a little worried about is that when I finish using it, I might not be able to use up every last bit of it..?
Tip
The tip is that it's nice to put the cosmetics in the refrigerator and use them, as they feel a bit cool. After washing your face, it also has a calming effect on the heated face. It's great!

Pros
This flows like a toner and cleanses the face in a water-type form. When applied right away, it is absorbed instantly. So it's great to keep it on the bathroom vanity, apply it right after cleansing, and then proceed with your basic skincare routine. After using this, I've noticed that my skin feels a bit smoother and softer in the mornings. It seems the gentle exfoliation is working, and my basic skincare products are also absorbing better. I'm quite satisfied with this product.
Cons
It is a bit inconvenient to apply it by hand as it flows too much. Since it is not a cheap product like a toner, I cannot just scoop it out and apply it like washing my face. I feel that using a cotton pad soaked in the product or a dropper-type container would be more appropriate.
Tip
It's more convenient to just dab it on with a cotton pad instead of directly applying it, as it's easier that way!

Pros
🩷The formula is transparent and watery 🩷It absorbs well and makes the skin texture smoother 🩷The mild exfoliating ingredients gently refine the skin, which is great 🩷The 8 types of low and high molecular weight hyaluronic acid provide excellent moisture repletion 👍 🩷When used as the first serum step for dry skin, it helps regulate the skin and acts as a booster for other skincare 🩷The skin feels immediately softened upon application 🩷The fragrance-free aspect is also a plus 👍
Cons
The formulation is well-absorbed like water, but it would be better if it were slightly thicker in texture.

Pros
Skin Type ღ Forehead - Oily + Acne ღ Cheeks - Dry + Redness + Sensitive ღ Nose - Enlarged Pores • • • Advantages ✅ The most gentle-feeling among the booster serums I've tried for sensitive skin ✅ LHA ingredient gently exfoliates after cleansing ✅ Despite being a booster serum, it has a good amount of moisture ✅ Effective in caring for acne caused by excessive dead skin cells
Cons
☑️ The boosting effect is less than expected ☑️ It has moisture, but it is difficult to address the inner dryness
Tip
The Aqua All-Day Keeping Serum, which is in the same line as the Hwahae, can be used together to achieve a boosting+moisturizing effect.

Pros
Typically, essences applied immediately after cleansing are often in a thin, watery formula like skin toner. However, this product is a slightly viscous essence. The amount is generous, and the packaging is neat. When applied, it absorbs incredibly well, without any residue left on the skin. I can feel my skin texture improving significantly. It seems to exfoliate very effectively. There is a subtle fermented scent to the product. It's not overpowering, but it's not completely unscented either. As it's a fermented product, this seems unavoidable.
Cons
Since it's First Essence, it would be nice if there were products with more volume. When using cotton pads to apply it to the face, you inevitably need more product, so... It would be great if the price were a bit more affordable.
Tip
The product description said to soak it in cotton and apply it, so I put it around my mouth where I had some flaky skin. The next day when I put on makeup, it had improved a lot. It seems like it would be good to put a little bit in when doing a natural face pack.

Pros
This is the perfect formulation to use as a basic booster before starting your real skincare routine. It's a gentle chemical exfoliant that works well for skin that finds physical exfoliation too irritating, especially skin that becomes more sensitive when using toner pads. It effectively removes minor roughness and light sebum, but it can be a bit irritating for daily use, so it's best to use it every other day or once a week. The watery texture makes it feel lightweight.
Cons
It seems to suit those with good skin or Hwahae Trial Reviewers. Those with very thin skin barriers are not recommended.

Pros
✔ A lightweight yet firm finish At first, I thought it was just a water-type product and wondered "Isn't it too light?" But when it absorbed into my skin, I was surprised by the surprisingly firm finish it provided. Right after application, it feels moisturizing and refreshing, with a smooth, adhering sensation without any tightness. It seems like a good fit for those who find sticky products burdensome during the summer. ✔ Effective for exfoliation When wiped with a cotton pad, it feels like the dead skin cells are gently smoothed out. Even without using a separate exfoliating product, it can lightly remove dead skin and refine the skin texture. Using it before makeup application helps the base makeup adhere much more evenly. ✔ Reasonable price Skincare products are meant to be used generously, and this one has an affordable price, so you can use it liberally without burden. Considering the ingredients and the effects, it seems to be a pretty cost-effective product.
Cons
For dry skin, using it alone may not be enough. While it has a good amount of moisture, it is not very moisturizing, so for those with dry skin, it's better to layer it with other products or apply a cream on top. It may be fine in the summer, but in the winter, it could feel a bit drying.
Tip
💡 For those with dry skin, Apply one layer first, and once it's fully absorbed, layer it on one or two more times. Finish with a cream on top, and the moisturizing effect will last much longer. 💡 When caring for dead skin, Soak a cotton pad with toner and gently wipe along the skin's texture to maximize the exfoliating effect. Using this before makeup will leave your skin smooth and allow the makeup to apply better. 💡 Recommended refrigeration! Keeping it in the fridge and using it will provide a cooling sensation, making it feel even more refreshing. It's perfect for soothing overheated skin in the summer.

Pros
This product is a runny type that fills in a bit of moisture when applied, so it's great as the first step after cleansing. The most satisfying part was the moderate exfoliation it provided. I used to have reddish skin around my nose that would get flaky, especially in the winter, no matter how much moisturizer I used, but that problem disappeared after using this product. Even stubborn small blemishes like milia that wouldn't go away before were cleared up around my nose. I used this serum along with a glutathione-based product, and I'm not sure if the synergy between the two or the serum's own effects were responsible, but I'll have to use it more to know for sure. However, the results were definitely not solely due to the glutathione product, as that hadn't worked before but did after I started using this serum. Anyway, I'm so satisfied with just that aspect that I'll definitely repurchase once I finish this bottle. It's not a heavily moisturizing product, so you'll need to apply a separate moisturizer, but as a first step for refining texture and gentle exfoliation, I highly recommend it.
Cons
The scent is.. not great. It seems to be a common scent in Galactomyces products, but I dislike it.. However, the effects are good, so I'll just use it. It's not to the point where I can't use it.
Tip
After using this product, it seems to work better if you additionally use glutathione or vitamin C products. I recommend trying them together.
