Reviv Serum is in bright yellow, I have to say, color little surprised and scared me, as most of the serums I have used, are clear or white-ish color.

At first I tried little amount on my hand - I was not a fan of its scent - it was very strong and almost medicinal and didn't fade much. After application serum seemed to absorb quite quickly, but left skin feeling little sticky.

I used it for little under 2 weeks and I can't say it worked for me. There were no visual skin improvements and I didn't like the sticky-ish feel it left my skin with after the use, nor could I get used to the strong smell it has.

Unfortunately I have to say, in my experience, serum didn't deliver it's promises and didn't work for me. But as we all are so very different, it might work better for you .
