Pros
I really wanted to try Retinol since I heard it was so good. After applying it, I soon felt a slight warmth and a sense of increased firmness. It absorbs well, leaving my skin feeling smooth and supple. Even though it's a Retinol product, it wasn't irritating at all, so I was able to use it without any concerns.
Cons
After opening, it deteriorated much faster than expected, so I couldn't use it for long and had to discard it. I need to use it up quickly.

Pros
As a beginner with retinol, the biggest advantage seems to be the price. Unlike expensive anti-aging products, it's great that I can experience retinol at a reasonable price point. Following the guide and gradually increasing the amount, I was able to use it without experiencing significant irritation. I usually mix it into the essence step or apply it after the essence, and with consistent use, I feel it has definitely helped with firmness. I have concerns about pores, and on the days I use it, I can feel my pores tightening. I think skincare products have more of a preventative nature, and I believe that even those in their mid to late 20s can comfortably use this as an affordable entry-level anti-aging product.
Cons
The main issue seems to be that the raw materials require refrigeration, which can be a bit tricky.
Tip
Mixing it with Aesence makes it apply a bit more smoothly(?) to the skin.

Pros
I tried retinol oil for the first time and it definitely seems to be good for improving elasticity. But since I'm still quite young, I ended up giving it to my parents after finding it a bit too oily for me. It seems to be great for caring for the eye area.
Cons
The downside is that it cannot be stored at room temperature and needs to be refrigerated.

Pros
I really like that I can easily use retinol. I apply it every other evening and my skin texture and elasticity have improved so much.
Cons
The only downside is that it's a bit inconvenient to store it in the refrigerator, but other than that, I'm completely satisfied with it.

Pros
It was easy to apply and felt good after use. It seems to have had a slight effect on skin elasticity. And it wasn't irritating at all.
Cons
Perhaps because the retinol content is low, the whitening or other effects were negligible.

Pros
My skin feels more supple. I bought it based on the recommendation of a friend nearby, and I don't think I'll regret it.
Cons
I haven't noticed any effects yet. I'll write a review after using it for a month.
Tip
I think the only thing is that it's supposed to be used only in the evenings.

Pros
I tried a retinol product for the first time and it's a very satisfactory product. At first, I wasn't sure, but the more I used it, the more my skin looked radiant and supple. After using it, my skin doesn't feel oily or sticky, and the application feels good.
Cons
The only downside is that it's a bit expensive for the amount. But the effects are good, and I only use it in the evenings and every other week, so it lasts longer than expected.
Tip
Just use it as directed. At first, I used a little too much, about 3-4 drops, and my face felt a bit stingy.

Pros
I'm sorry for the late review, as I mistook the date. The reason I applied for the trial is that the retinol concentration of 0.5% is mid-range among high-potency products, and I wanted to get help with the increased pores and loss of elasticity from wearing masks. The fluid texture is easy to apply, and it doesn't feel oily or sticky, which I think is good, and it absorbs quickly. What I liked the most is that it absorbs well without any stickiness. I'm applying just a drop at a time to get my skin used to it without any irritation, and since it's not irritating, I plan to increase the amount after about 3 more weeks. For someone like me who finds refrigerating it after opening a hassle, it seems like a good product to use in the current season.
Cons
I think it probably has some fragrance. But for me, if functional products or products with mineral sunscreens don't have a distinctive scent, I feel uneasy.
Tip
Both the first and second products are sunscreens. Be sure to apply sunscreen.

Pros
During the seasonal change, my skin has been feeling very tight and, now that I'm in my 30s, I've also been concerned about maintaining skin elasticity. However, just applying this oil has left my skin feeling moisturized without feeling overly greasy. Once absorbed, my skin feels soft and smooth. The more I use it, the more refined and even my skin texture becomes.
Cons
I didn't really have any complaints, but if I apply makeup or sunscreen on top of it before it's fully absorbed, it can feel a bit slippery. However, I didn't experience any irritation, which I was worried about.
Tip
This product seems well-suited for nighttime use.

Pros
As the weather has become increasingly dry, using highly concentrated products seems to be a good way to regain skin elasticity. I was surprised to feel a noticeable difference in my skin the very next day after using the product. The brand's attention to environmental impact, from the packaging to the delivery box, was evident and reflected in their brand image.
Cons
While the usage and storage may be a bit tricky, the effects are good enough to make it worthwhile. There is a distinctive scent, but it fades over time.
Tip
As it is a highly concentrated product, an adjustment period may be necessary! It might be helpful to assign specific days of the week to use the product, as it is not meant for daily application.
