It's just right to use it after pumping it a couple of times.

There is hardly anything, and the courage is unclear, so I cannot confirm the remaining amount.

I wake up and touch my face, and the difference between applying it and not applying it is significant, so I apply it every evening.

옵티멀 하이드레이션 48 시간 액티베이션 세럼

The amount seemed less than expected,
and it was disappointing that I couldn't see the remaining quantity. I should have bought one more in advance.

This one alone applies moisturizing and not heavy!
There are no troubles either!

None, but the price is a bit steep... However, I can tolerate it.

I really liked the application, but I don't think I'll repurchase it. Haha.

The price is a bit disappointing... It would be great if the price was also affordable.
⭐️ And despite the product name, it's not extremely moisturizing.
It's between a lotion and a cream, with less oiliness than a cream.
The texture is a bit closer to a cream.
If you're looking for intense moisture absorption and a super dewy finish, you might want to consider a different product.

My skin type is 😭dry, sensitive, and atopic.
✔️When choosing cosmetics, the most important factors for me are sensitivity and dryness. My skin is really thin 😢
I received it as a gift and used it without any expectations, but surprisingly, it didn't irritate my skin at all and was very gentle.
I may not have had high expectations, but I'm going to repurchase it.
My skin is so sensitive that even a small mistake in using products can cause my skin to break out in hives, but this one seems to work well for me.

Despite the name 'Optimal Hydration', the moisturizing effect doesn't last long (after 2-3 hours, my face isn't dry but not as dewy either).
The product seems good, but there may be others like me who it doesn't suit.
I'd recommend this for dry skin types who don't necessarily need heavy-duty skincare functionality.

1. Glycerin...
Glycerin as an ingredient is not necessarily bad, but it doesn't agree with me.
If glycerin is among the top 2-3 ingredients, my face always feels irritated.
If you don't get along with the Kiehl's Hydrating Cream, this one may not work for you either.

2. Sometimes it applies thickly and has to be smoothed out.

3. Caused stubborn chin blemishes... The only product I've changed in my routine is the Optimal Serum Cream, and now I'm getting these hard, stubborn blemishes on my chin. It's not around my period, so it seems this product just doesn't agree with me. I've stopped using it.

1. Thick, adherent application feel.
Although it is a serum, it is not watery and has a lotion-like texture. It applies a bit thickly, but adheres well to the face, providing a pleasant feel. I recommend this for dry skin types.

The amount seems a bit small.
Other than that, I'm satisfied and continue using it.

It has a smooth and creamy application that keeps the skin moisturized for a long time, so it doesn't feel as dry.

The fragrance is really not good... Seriously... It smells like the unpleasant clay I used to play with as a child......

It has a quite moist and soft texture, making it easy to apply.

It worked well for my dry sensitive skin, but it seems too heavy for oily skin types to use.

My atopic sensitive skin has no irritation at all, and the moisturizing effect lasts for a long time.

The volume is too small. I wish they had a larger size.

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.^^

I didn't really notice any particular effects. It was just average.

The formula was moisturizing yet not heavy, making it comfortable to use. I used this product daily and it worked well for me.

For someone like me with dry skin, I need to apply toner, essence, and this product about two times to get adequate hydration.

It has a faint rubbery scent, so those sensitive to fragrance may not like it.

While it has good absorption and moisture, it has a slight warming sensation and my dry skin still feels a bit dehydrated, so I need to use other products along with it.

The serum's formulation is a bit different from what I had expected. It has a moisturizing lotion-like texture.
It's not greasy, so it should be suitable for those with oily skin.
However, it may feel a bit drying for those with dry skin.

It has good absorption and is non-irritating to the skin.

This may be a good moisturizing serum for people who don't usually have trouble with basic skincare products~

‼️ I have a sensitive skin that easily develops contact dermatitis, redness, and small pimples when I use the wrong basic skincare products.
‼️ When I applied this serum, I immediately felt a stinging sensation.
‼️ I'm not sure if the 48-hour moisturizing claim is accurate, as the moisturizing power seems similar to other essences or serums.

✨The texture is amazing. When you think of a serum, you usually expect a transparent and watery texture, but this product has an opaque and slightly more solid(?) feel, like a cream.
✨The application is also interesting. Despite the opaque texture, it doesn't apply thickly like a cream, but rather smoothly and moisturingly, like water seeping in.
