Pros
It's famous for a reason! This product is fantastic at tackling deep dryness, and its affordable price makes it perfect for generous use. When my skin feels parched at night, I layer this over my emulsion, and I wake up without any dryness. It's absolutely wonderful! I plan to keep purchasing refills.
Cons
There are no drawbacks! It's not irritating at all, and it doesn't cause any blemishes to appear.

Pros
As someone who's on their third bottle of this product, I can attest to its effectiveness. My skin was in terrible condition due to constant mask-wearing, but this serum has been a game-changer. It tackled my deep dryness and cleared up the persistent blemishes on my cheeks. It's also great for soothing the skin! I've tried everything when my skin suddenly broke out - changing pillowcases, exfoliating, applying various acne ointments, and even visiting dermatologists. Nothing seemed to work significantly. The first photo shows my skin shortly after starting to use this serum. You can see the bumpy areas and spots where I've applied acne patches - all blemishes. Actually, this was after the cystic acne had subsided and some of the smaller blemishes had started to clear. My skin was so bad before that I didn't even want to take photos. The second photo is after about 5 months of use. I was amazed at how the blemishes had almost completely disappeared, leaving only some minor scarring. As you can see, my skin is smooth apart from the faint marks. Interestingly, when I stopped using this serum for about 3 weeks, the blemishes on my cheeks started to return. Since then, I've made it a staple in my routine, stocking up during sales. It manages my deep dryness and prevents breakouts - I'm much more satisfied with this than with dermatologist treatments. - User experience: The texture is like a runny liquid, making it easy to apply. The dropper applicator is hygienic and convenient. There's hardly any cosmetic scent. I experienced no irritation whatsoever.
Cons
It's slightly inconvenient that it doesn't come in a larger size, so you need to replace it frequently. However, the product's effectiveness makes it irreplaceable.
Tip
I've found that using a hydrating cream with hyaluronic acid after applying this serum works better for my skin condition in the morning compared to using an emulsion. I highly recommend this for those with dry skin!

Pros
This product is characterized by its lightweight application and excellent absorption! The finish is superb, and it's not too sticky, making it a pleasure to apply. Despite its light texture, it gives a feeling of locking in deep hydration, making it perfect to use before makeup. I was even more satisfied because of its affordable price!
Cons
There weren't any disappointing aspects! The texture is slightly lightweight, so you need to be careful when pressing the dropper. But I wouldn't consider this a drawback. Just be gentle when using it and you should be fine!

Pros
I've tried many famous ampoules for deep dryness, but this one seems to work best for maintaining hydration. In winter and spring, layering this with an oil-based ampoule really helps combat deep dryness.
Cons
Since I can purchase it at a reasonable price, there's not much to complain about.
Tip
Mixing it with other ampoules when applying has reduced my deep dryness.

Pros
When I purchased the gel cream, I received a sample as a gift and loved it so much that I ended up purchasing the full-size product. I've used up two 50ml bottles and feel like I'll be using this product for life, so I bought it in bulk. The formula is lightweight and absorbs into the skin, leaving it moisturized with just a couple of layers. If you apply it without touching the skin, it also helps reduce skin irritation. I've been using this product incredibly well throughout all four seasons!!! Just as the product name suggests, it's an 'Effector' that significantly improves skin condition.
Cons
The feeling between toner and ampoule is such that you must apply a moisturizing cream as well. However, as I have oily skin, in the summer I just apply this twice and that's the end of my skincare routine.

Pros
🧴 Skin Type • Sensitive Skin Trouble • Dry Skin 🧴 Usage Experience • The watery formula spreads easily and absorbs well without leaving a dry or sticky feeling! It was really great. 🧴 Overall Evaluation • I'm not sure about the trouble-soothing effects, but at least my skin troubles did not worsen. It manages dryness well, so I'm on my 4th bottle of this product!
Cons
The product may feel less moisturizing for those with extremely dry skin. It is not recommended for those seeking strong soothing effects for skin troubles.

Pros
First of all, I liked that the texture was not too heavy and the finish was refreshing! When the texture is heavy, it's inevitably only used in the evening, but this one is not too light and has a moisturizing texture, so it's good to apply it frequently. After application, a moisture barrier-like film forms, so there's no tightness or discomfort at all, which I really liked❤ Coincidentally, I had a breakout, so I used it consistently, and I was surprised to see that the redness disappeared and the blemishes calmed down after using it. I was worried that it would have a strong medicinal scent because it contains licorice, but I was satisfied that the fragrance was better than expected>< There also seems to be a mild cooling effect, so it was good to use it when my face felt flushed to quickly cool it down. Honestly, other functional ampoules are often too heavy or sticky, so I didn't reach for them much, but I think I'll continue using this one going forward😍😍
Cons
Dry-skinned individuals may feel dry if they do not apply additional cream.
