"In our clinical study, the Algenist Concentrated Serum delivered incredible results in just 10 days, decreasing the appearance of the size and number of deep wrinkles by 28% and 25%, respectively. Here's an insider tip: women in this study only used the serum once a day. I like to use the Concentrated Serum twice a day because I love the way it makes my skin look and feel. And let's be honest — when it comes to comprehensive anti-aging results, the more the better."

—Tammy Yaiser, Algenist Product Developer

What is it: An advanced antiaging serum formulated with the revolutionary, patented ingredient alguronic acid to help reduce the appearance of fine lines and deep wrinkles, improve firmness, and bring radiance and luminosity back to the skin.

Who is it for: Anyone experiencing fine lines, deep wrinkles, loss of skin firmness, and a lack of overall radiance.

Why is it different: Concentrated Serum is formulated with alguronic acid, a unique, patented compound from microalgae. This rare ingredient was discovered unexpectedly by a biotechnology laboratory in San Francisco focused on researching renewable energy solutions.

How do I use it: Apply a small amount of Concentrated Serum to the entire face morning and night after cleansing. Use only as directed.

From Algenist.

Algenist Concentrated Serum 1 fl. oz. is rated 3.1 out of 5 by 559.
Rated 5 out of 5 by from The Absolute Best Serum There are two reasons I ordered Algenist Concentrated Serum. First,Tammy Yaiser has a special personality and as she described the serum I found myself watching and listening more closely. She spoke with a calm, grounded assurance that impressed me. Second, there are clinical reviews, not product reviews by customers. But mostly, the serum WORKS! I am so excited. My neck and décolleté wrinkles have reduced significantly, as have wrinkles in other areas. No product I have ever used has worked like Algenist Concentrated Serum. I am honestly and sincerely promoting this product above any I have ever used. Try it and see for yourself.

Rated 5 out of 5 by from Amazing! I have problem areas with wrinkles and bags under my eyes. I have tried many products from different brands and nothing helped much except to improve the situation temporarily. After using this product for a couple of weeks once a day, my baggy areas under my eyes are very smooth and wrinkles have diminished significantly, the area looks smooth even when the product is not on my skin! I am completely blown away by the results, frankly did not think it was possible, I am glad I have the bottle in super size!

Rated 5 out of 5 by from Miracle in a bottle I was fortunate to purchase this in the mega size when I happened upon it one night while watching QVC. I waited a few weeks to write a truthful review, and I have to say my skin has never looked better! I have been using this product a little over a month now, and only once a day in the morning, and today I got a good look at my face sitting in my car looking in the mirror with no make up. I couldn't believe how smooth and glowing my skin looks! My pores are much diminished and I could see a difference in my fine lines and wrinkles. I am 64 years old and feel that my skin looks at least 20 years younger! My face feels very smooth and soft to the touch. I do use other QVC skin care products on my face but I must say I think that this added that extra special touch. I will continue to buy this product. And it is a great value for this size and I only use one pump so this will last me a long time. Try it! Give it a few weeks using it every day and if you get the same results as I did, you will be so happy you purchased it.

Rated 2 out of 5 by from ITS BEEN 30 PLUS days and I'm still seeing no results and that is with using once a day as directed in presentation and I'm using DR D's Essential Lipid Power Infusion at night. This gets 2 stars because it does help my moisturizer hold up better but as far as results in 10 days according to their studies. Didn't happen on my face. The tests must be flawed because even after 30 days I see NO RESULTS. I will be canceling the auto ship and just use this till it is gone. It will be awhile because I got the Mega size but the system would not let me review it for that size so I'm doing it here.

Rated 1 out of 5 by from Tired Of Empty Promises I got the supersize bottle of this serum. It has been the ten days for promised results and I'm still waiting. There has been absolutely no change in my skin! I don't know where they get their clinical results, but I think it's time for another study. I'm tired of hearing these 10 day to two week promises on some of the beauty products sold on QVC and seeing no results. After reading reviews, I see I'm not alone. I'm going to give it 30 days just because I can but I don't have any hope I'll see a change; do then back it goes.

Rated 5 out of 5 by from Beyond belief!!!!! I only write reviews if something performs above and beyond or is not worth it. I bought this in the 4oz size but couldn't find a link to write a review on this but the 1oz is the same product. I have used this only three times and my skin has a totally different texture. My pores or 65% smaller. I said something to my husband and he looked really close and he said oh my god it looks like someone else's skin. I'm not kidding it is that dramatic! I have paid so much money for products that did not live up to their claims and was hesitant about this but I will never be without it again.

Rated 5 out of 5 by from good purchase for me With hesitation I recently purchased the Huge bargain size (4 oz $130) & on easy pay. I tried several Algenist "try me size" early on QVC but not this Serum. (I consider Algenist off limits financially). And we are all aware of endless antiaging competition IT IS BIG BUSINESS. After pondering (but before the offer ended) I ordered on easy pay and like other reviewers It is proving the advertising on my skin. Firming & improvement deep wrinkles. And that is a BIG DEAL for my skin since I was a CHEMO victim back in the 80's which changed my life. I finally learned Retinol works against me, and this serum has no retinol which impressed me to try it. Money is very tight with me but I treated myself with the 4 oz size which will last a long long time and BTW the container is frosted glass & the pump works perfectly!

Rated 5 out of 5 by from Product Works Effectively! I have used this serum for 5 years. It is the only product that has effectively worked on my face, around eye area, and yes, even neck. I am now 63, and am so often told I look in my early 50's with beautiful skin and complexion. Since I've never used foundation, having good smooth, firm, yet elasticity has always been my goal. I found it in this product. I love it! You dont need a lot of other stuff, except SPF moisturizer.
