Rated 5 out of 5 by from Love this I just started using this serum about 2 weeks ago and I love it. I feel and see the difference. I see a lot of the redness on my chest is gone. I have been using it there as well. I will continue with this product. once I run out I will order again. Also love the size.

Rated 5 out of 5 by from Fabulous I love all of Algenist products, have been using algenist about two years. I love the night cream. You wake up glowing. When QVC had this on a special I knew I had to try it. My daughter and friends at work noticed my skin being smoother and more even toned. After a few uses I now can go out without cover up. It's a phenomenal product!

Rated 3 out of 5 by from Still waiting I like this product so far but I'm still waiting for the first 10 day trial period. My skin is pretty wrinkly so I hope it will make a difference. Did not see a difference so far.

Rated 5 out of 5 by from Best Serum I love this serum! Sinks right in, not greasy, not sticky! And my skin looks like porcelain. Wow, good stuff! I wear under makeup or under the Algenist tinted moisturizer. A lot goes a long way! Treat yourself!

Rated 1 out of 5 by from Easily Broken Loved the serum for three days before the glass broke. Do not pick up front top as it will not hold the bottle. Lost all serum to broken bottle on bathroom sink.

Rated 5 out of 5 by from Wonderful Serum I'm 71 and have always been told I look 20 years younger than my age. Part of this is being lucky enough to be blessed with good genes. The other credit goes to Algenist products. Since Algenist introduced this serum, their eye firming serum & their day cream, I have seen the few little lines around my mouth disappear. I've tried every skin care line from expensive to drugstore. This is the best.

Rated 5 out of 5 by from Like this Product I have only used this product for a few days but I see brightness in my face. I am 50 plus years and have sun damage. The price for this is really good since elsewhere the price is very high like $90 for 1 ounce. I hope this will help lighten sun spot on cheek. I think this is a good product. No smell. It is light texture too.
