I’m big fan of Reviva labs products. They have no fancy packages, just simple package, but full of quality. Very good prize vs quality combination. I tried some expensive products, but those were too sticky and I got pimples. This product is not sticky. It goes lightly in to skin. I use this before Reviva collagen night creme and my skin is so soft and bright. I’m aged 50 and I have minor wrinkles. I live in Skandinavia. Reviva is perfect for my skin.

Excellent product, leaves my face soft and has help me with fine lines, It does plump the face. My skin looks great now. I am very please with this product, has been using for a couple of months, applied every morning and evening after I clean my face. I wait until dry out and the applied my daily or night cream. You can see the difference in about a week.

Good quality product and great value for money. I just didn't notice any difference so I'm not sure it's the best product for me.

Hyaleuronic acid is the finishing step in my facial routine that seals in the moisture. Great product that’s easy to apply.

Very good product! I use it with other face serums and creams together. The result is on the face , it is perfectly good!!!! Will buy again!

Unfortunately hyaluronic acid had the opposite effect on my skin and instead of adding moisture my skin dried out. It appears that this may be due to the fact that I live in an area with very low humidity and this acid is not suitable.

Did not like so much the texture and efficacy compared to my other usual brand

Good serum. I found another product that I like better, but this is a nice, hydrating serum if you are only looking for hyaluronic acid.

Best Quality , size , packing and good

Amazing product for my skin care routine
