initially I wasn't planning to buy this serum and now I think I would take it all the time! I had already used lots of hyaluronic acid products because I have very dry skin but I was never really satisfied with the result. now that I've tried this serum I finally have a perfect moisturizing product! I don't know how to describe it but the sensation upon application and over time is magical! I recommend !

the capacity is small, this serum is worth the cost, the skin is plumped, the texture is not very watery liquid and we feel good in this serum, it is the ceramists who provide this comfort.

LOVED this product. absorbed really well into the skin, wasn’t sticky or too thick but it doesn’t last. using it sparingly day/night it still only lasted about a month maybe month & 1/2. the dark colored bottle makes it impossible to tell how much is left inside

this serum is all I need to hydrate my skin, the only problem is the bottle is too small and I wish I could get the product in a bigger size.

Hyaluronic acid helps skin stretch and flex and reduces skin wrinkles and lines. Hyaluronic acid is also proven to help wounds heal faster and can reduce scarring. It moisturizes your skin and keep your face plumped , the quantity and quality is amazing

I really love this serum so much. it is work well on my face, too thick and reduce acne. it is also control oil on my face and working so fast with my pimples.

It’s my first serum from this brand and not only it is good but it also had a cool package/bottle, it makes you look professional ahahah

I got this hyaluronic acid together with retinol oil both from cosrx. Use hyaluronic acid before applying retinol. A good combination.

This is one of the best Hyaluronic Acid Serums I have ever used. I love that it also contains ceramides and amino acids anything with ceramides in it is my favourite, but from using this product I could see a visible difference in my skin and the improvement in my moisture barrier was noticeable! Will definitely be repurchasing!

as good as other corsx products! although I like the retinal collection more. it's gentle, hydrate and safe to use at a daily basis! highly recommend.
