Pros
I won a free event and tried this product for the first time, and it was so good that I bought it with my own money~^^ I have dry skin and my face used to feel tight, but this product alone solved the problem of dryness even in the middle of winter^^ It's not too heavy or sticky, so I decided to buy it again. When buying cosmetics, I check the ingredients, and while there are some caution ingredients, they're not too bad. My skin is quite sensitive, but I've been using it without any problems. This time, I bought two and gave one to my mom.^^
Cons
The volume is too small. I wish they had a larger size.

Pros
It's great that it's just the right amount of moisturized, doesn't feel heavy, and helps with inner dryness! The compact size also makes it convenient to carry around. It's perfect for sensitive and dry skin.
Cons
I don't have any major issues. The amount for the price feels a bit small, but that's the only thing I can think of.

Pros
👍🏻 It helps maintain a good balance of moisture and oil. - As the weather got colder, the basic products I was using before were not enough to solve the tightness, but after using this product, the tightness has improved a lot. It's not overly oily at all, so it was great to use. 👍🏻 Soothing - The milia on my cheeks have settled down a lot. 👍🏻 Fragrance-free - It has a slight ointment-like scent, but it's almost fragrance-free, which I liked! 👍🏻 Texture - The texture is between a cream and an emulsion, so it's easy to apply and adjust the amount.
Cons
🤔 The opaque packaging makes it difficult to check the remaining amount. 🤔 The volume is small. It would be better if they made it in a larger size...

Pros
I use products with good moisturizing power and oiliness from early fall to winter because I have severe dehydration. In the summer, just two steps of essence and lotion are enough, but in winter I increase the steps to skin+essence+cream+night pack to thoroughly moisturize from the basics. I had high expectations for Cetaphil, which is famous for body moisturizing, and the moisturizing power is really the best as advertised! • Texture: Although it's called a serum, the texture is close to a cream. So I'm applying it after skin and essence. • Fragrance: If I consciously smell it, there is a slight scent similar to the Cetaphil body lotion, but it's almost fragrance-free. It's a mild-ingredient cosmetic that doesn't use harmful ingredients or animal-derived materials! • Moisturizing power: I really, really recommend it to those who suffer from severe dehydration! I really suffer a lot from dehydration. When I didn't know much about dehydration, I thought just filling the dry surface of the skin would be enough, so I slathered on the oily cream my mom used, but the dehydration wasn't filled. After going through several winters suffering from dehydration, I realized that filling the inside is much more important than the outside! If you build up from the skin and apply the Optimal Hydration Serum before the cream, the dehydration doesn't feel noticeable!! As the name suggests, it feels like the 48-hour moisturizing power is sustained.
Cons
• Packaging: The pump-type packaging is hygienic, but it's disappointing that I can't check the remaining amount. The capacity is small, so it seems like it will be used up quickly, but it would be better if I could use it up cleanly without leaving any behind.
Tip
• How to use: In the dry winter season, I apply it all over my face before the cream. Since the container is small, I carry it with me to work and apply a small amount to my eyes or neck whenever it feels dry. Now that I'm at the age where wrinkles start to form, it might be good to use it as an eye cream in other seasons as well. Moisturizing is important for wrinkle prevention, and I'm really satisfied with the moisturizing power of this product.

Pros
Skin Type: Dry and Sensitive The absorption was quick and the application was not sticky. After application, I felt a sense of elasticity on my skin. In the evening, the tightness came back quickly, which was disappointing, and I thought the tightness would be severe in the morning when I woke up, but there was no tightness :) It seems the moisture and oil balance is well-maintained. There was a burning sensation and tightness, but it was quickly soothed, which was good.
Cons
The volume of 30ml was disappointing. Since the container is not transparent, it is impossible to check how much is left. Due to the home environment and season, the tightness came back faster than expected, which was disappointing. This seems to be because my home is extremely dry.

Pros
I've been using the well-known Cetaphil for a long time, and I trusted it. It certainly feels like it effectively addresses dryness, as it claims to provide 48-hour hydration. While it may not be considered a serum per se, the formula is closer to a cream, but it doesn't feel greasy or oily after application. It's perfect for my dry skin type if I adjust the application order properly!
Cons
It has the distinctive Cetaphil scent. If you haven't used other Cetaphil products before, it might have been difficult, but considering it has fewer harmful ingredients compared to others, it's not too bad. I didn't feel any tightness, but my skin suddenly became quite dry, and looking in the mirror, it does appear a bit dry. My skin is naturally very dry, though. Still, it's better than many other serums! The volume is very small. It might not be too much of an issue if it's a product like an ampoule that you use just a few drops at a time, but using one or two pumps per application with this size, it feels... almost travel-sized? Considering the price, I'm not sure if I would buy it again.
Tip
Normally, I apply toner, ampoule, and cream after cleansing, but this time, the Hwahae Trial Reviewer suggested applying the serum after the toner and before the cream. Since the ampoule is quite thin, applying the thicker Cetaphil serum after it felt a bit odd to me. I think it's best to apply all the lightweight, watery base products first, and then use the Cetaphil serum right before the cream step.

Pros
Even if you apply highly functional cosmetics, if the skin's pH and barrier are not in a healthy state, the products will not be effectively absorbed. That's why it's crucial to first restore the skin's optimal pH and strengthen the skin barrier with gentle, high-moisture, and high-hydration serums like this one.😍 I was already a fan of Cetaphil's body care products, knowing their excellent moisturizing properties. But I had no idea they could create a skincare product that is an absolute game-changer.❤ I'm completely smitten!ㅋㅋㅋㅋ I'll be sure to continue using this diligently even after giving birth to maintain healthy skin.ㅠㅠ This is a highly recommended review~~~!!
Cons
There were no downsides for me~ I just hope they come out with a larger size version in the future.ㅋㅋㅋ
Tip
I found that using an exfoliating pad to gently remove dead skin cells before applying the serum really helps it absorb better. Be sure to do thorough exfoliation during the winter months to keep your skin in top condition~~~

Pros
This is a product I can recommend, especially on days like these when the temperature difference is severe and the cold wind is blowing. When your skin feels extremely dry, to the point where it seems to be cracking from the outside in, this product really helps reduce that deep dryness. It doesn't just replenish moisture, but also helps balance the oil and water levels in your skin. Your skin will feel incredibly comfortable. The more you apply it, the more your skin will feel firm without feeling burdened. This is a very reliable, back-to-basics product.
Cons
This isn't the kind of product that will instantly make your skin glow, smooth out wrinkles, or have you seeing dramatic effects the moment you look in the mirror. It's a basic, reliable product. But for busy modern people who have to rush to wash their face, apply various cosmetics, and head out the door in the morning, I'm not sure how much it will appeal to them.
Tip
On those days when you really can't be bothered with applying a bunch of things to your face, try just cleansing and applying this product along with your toner. Normally, with all the different products we layer on, it can be hard to tell which one is really making a difference in the firmness of your skin. But using this product on its own, you'll be able to better feel that strengthening effect.

Pros
I was familiar with the Cetaphil brand as a body lotion. I had high expectations for the hydrating serum, emphasizing quick absorption and a moisturizing finish. I thought the formula would be a light, watery texture, but it turned out to be almost like a lotion. The fragrance-free aspect was great, as I don't like artificial scents. I follow a three-step skincare routine of applying toner, then serum, and finally a moisturizer. Even in this chilly weather, I didn't experience significant dryness, as my skin maintained a nice level of hydration. The serum has definitely kept my skin feeling plump and moisturized!
Cons
I was a bit disappointed that the formula wasn't as lightweight as I had expected. Additionally, the price point feels a bit high compared to the amount of product, unlike the body lotion.
Tip
I would recommend using a watery, hydrating toner or essence first, then applying the serum, and finally following up with a richer, more occlusive moisturizer or cream.

Pros
At first, when you squeeze it onto the back of your hand, you might think 'Why is it so thick?' but when you spread it out, it applies smoothly and leaves a moisturized feeling - it's a surprisingly unique texture!! I'm currently undergoing treatment for seborrheic dermatitis, so I haven't been able to use it every day, but I haven't experienced any significant irritation or side effects, so the ingredients seem gentle and well-suited for me. Even though I have very dehydrated skin, when I apply a watery product along with this, it seems to effectively relieve the dryness.^^
Cons
It's not completely unscented... It has some kind of natural ingredient scent, not an artificial fragrance. It's similar to the smell of the Cetaphil body lotion, but the scent goes away after application. The packaging is plastic, so it has a slightly cheap feel to it ㅠㅠ The product itself is good, but the packaging is a bit disappointing~!
