This serum is very moisturizing. It gets absorbed into my skin very fast and do not leave a sticky or dry feeling.

This serum really helps with retaining moisture, skin feels great the morning of applying it as well. The smell is pleasant and the serum has a great consistency. Not too light, not too thick. Overall worthy of being in the vanity.

The serum provides good moisture and soothes my rosaceic skin.

It provides just the perfect amount of hydration without making my skin oily or greasy. And yes, it lasts all day. So I'm giving it a 5 for that. It will be too light to use in the colder months but I find it amazing on my skin on a summer day.

Moisturizes well. It smells the same as a niacinamide mask. It gently cools while applying it to the face. After using this serum, the skin is smooth and there are fewer skin problems. It's possible that these serums plus the mask are doing a great job.

This serum is an excellent choice for my dry skin. During pregnancy extremely dry. I use it every morning and it gives me sufficient hydration. Consistency is sth between gel-like and watery and it is almost without the smell. Also a perfect fit for my extremely sensitive skin. No irritations. I use it on wet skin and one pump is enough for the face and neck.

I really like this serum because it is very moisturizing. It works wonders for my super dry skin. I like to use it especially in summer.

Oh my god this serum is god sent. I’m on my second bottle and will buy again and again. It does have a little thicker texture but I’m not bothered by it. Gives your skin some good hydration.

I am a huge fan of Klairs and this serum is no exception. While the product does not offer anything "extra" aside from hydration, this serum is a pleasure to use. The serum feels cooling on the skin and is perfect to use in the summertime. It leaves my dry skin supple and smooth under makeup and I find myself reaching for this a lot when I want something soothing and fuss free.

I just received my product today and I tried it a few hours ago: it has a really good and refreshing smell, I feel hydrated well and even though the product dry really fast on your skin you don't feel it at all! I might update this in a few days to see if it's really working or not!
