"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 552.
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.

Rated 5 out of 5 by from It works I received this item and could not wait to use it. I applied it once in the evening. The next day I used it A.m. and P.m. When I awoke on the third morning, I could not believe it. My pores had all but disappeared and my chin acne had cleared up. Clogged oil glands that made small bumps on my lower cheeks and jaw line had diminished by 50%. I AM SO PUMPED! After two years, I have found my answer. Alguronic acid definitely works for me! I had received a small sample of the firming and lifting cream in a purchase with gift and I had used it up because it had reduced puffiness. I finally made the decision to spend the big money on the serum. So thrilled!

Rated 5 out of 5 by from Great Serum for Fine Lines and Minor Wrinkles After using this product for a month, I can see a noticeable improvement in the fine lines and minor wrinkles on my forehead and around my eyes and mouth. It doesn't get rid of them - but nothing in a bottle will! My skin can be somewhat temperamental and break out with new products, but I have not had a problem with this product. It does not make my skin oily or dry as some other reviewers have experienced - it is completely unnoticeable under my moisturizer. I also appreciate the fact that, unlike many serums, this does not have a noticeable scent. I have seen more improvement with this product than with other serums and will continue to use it. I have also seen great results with some of the other Algenist products and recommend them as well.

Rated 5 out of 5 by from It really does WORK!! Back last year "Algenist" burst onto the skincare scene!! Of course, I was critical & had my reservations!!! Here comes another overpriced jar of "something"which will promise the moon, stars, anti-wrinkle potion!! I tried it & was so surprised with results I was seeing from incorporating this "Serum" with my other nightly skin-care regime!! I decided to by pass all their other new skin-creams (gave them a try as well & had to send back :( ...... You're able to put this 'Serum' everywhere on your face, upper eye brows, close to your lip line area etc . I'd say it's worth every PENNY!!!

Rated 2 out of 5 by from Preview Your Review I'm on the second bottle of this, am going to cancel Auto-Delivery. It's no better on skin texture or wrinkles than any other serum I've tried, and leaves my skin far more oily under makeup -- not a result I like.

Rated 1 out of 5 by from Disappointed I have been using since 1st of July. I took the picture as they suggested and there is absolutely no difference none. So if clinical studies show 25% change it absolutely did not do that for me. My skin looks no better. The elevens have not changed at all. I know nothing is going to "erase" the small lines but I so dislike all the promises. I feel that I gave this a fair chance and will use all of it. But definitely will not repurchase. I have the super size
