This serum works great.

This serum works great. I have dehydrated skin (dried out by air conditioning), and I’m 37 years old. I saw results within a month. Though the bottle only lasts about a month :) I apply the serum to damp skin after toner (it’s very important that the skin is moist before application—hyaluronic acid loves that), then I seal it in with an occlusive cream from the same brand. My pores tighten, and my skin looks plump and glowing.

Good quality

I used this once a day , which brings me to tell u about the size it ran out fast compared to my other serums however it’s gentle and great for sensitive skin, it benefited my skin and it’s great for moisturizing , overall it was a really good product with luxury packaging

Love the hyaluronic, hate the bottle

I usually use the most economic hyaluronic with the O brand, but I still find it not moisturizing enough. So I got this to try with my age of 40 skin loves this. Skin has great absorption and does not ball/pill when I apply a face oil after. I do hate the packaging where I cannot get the last drip with body of bottle is black and shape prevents me from getting the very last drop.

Amazingly hydrating serum

Probably the best hyaluronic serum I’ve tried, the serum is highly concentrated and not watery as the similar serums always are. No scent whatsoever, my skin is normal and I love this I think is also will be suitable for sensitive skin. The only downside is that the amount is quite low only 20ml but the quality is top. Definitely a 5* rating I’ve repurchased my second bottle even before I run out.

Hyaluronic acid serum

Absolutely love this serum! It deeply hydrates my skin and gives it a healthy glow. The texture absorbs quickly and makes my skin feel plump and smooth. Great value for the quality!

The product is great for my dehydrated skin. I am 51 years old. I used it in the morning before my cream and spf. I will not order it again because the packaging is terrible.

Great product

I hoard COSRX products because they all work great on my sensitive skin, and I love that they’re unscented. I use this product morning and night to keep my skin hydrated, and I can really see how effective it is.
