For the price I think there are better hyaluronic acid serums for less. The smell is not so pleasant.

Not a fan

I received this product to test out for free with Influenster. I was excited to try this serum since it was the first Sunday Riley item I had ever tried but I was left pretty disappointed. The product has a scent to it which never works well with my skin since it’s so sensitive. The consistency feels really nice once pumped out but I couldn’t get past the scent. If your skin isn’t sensitive then this product might work well for you.

Incredibly hydrating!

I really like this serum a lot it is very hydrating and plumping I noticed, the first time that I used it. didn't notice any smell at all, and I thought it was lightweight but not too lightweight. I definitely recommend this serum if you're looking for a very hydrating yet plumping add to your skin care routine. I like to use this in the evening and mix it up by using CEO vitamin c serum at night a few nights a week, and always the vitamin c serum in the morning. Using them both is incredible for your skincare!!

Terrible smell

Not sure how well this works bc I also can’t get past the smell. Someone described it as sea urchin which perfectly describes the weird strong fish smell.

Ok product

The product is ok. But I just can't get past the werid smell, it is just awful. I tried to mix it with my sunscreen, also my lavender face spray, but the fishy smell still lingers.

Allergic reaction!

Something isn’t right with this serum.. The first time I applied it, it caused tremendous itching and dryness in my eyes even though I haven’t applied it anywhere around eye area. My eyes were BURNING and bright red, it took several rinses and washing my whole face thoroughly to calm that down. Then I decided to use this serum as hand moisturizer.. didn’t make me wait long, my skin started to itch BAD with little bumps.

Stay far far away!! Danger! Danger!

Bought this on 4/13/26. How is this allowed on store shelves!! Read the reviews but still decided to try. Holy moly did I make a mistake!! My skin immediately got blotchy, burned and turned bright red! The product started to peel. It’s been 15 minutes and I’m a hot mess! Buyer beware!!

Burned my face!

This product burned my face!! I did a patch test on my arm and was fine, then applied to my face and immediately had a terrible reaction of burning and redness. Would not purchase!
