What is it: This dual-action anti-wrinkle firming serum, which is gentle enough to use every day, helps improve the appearance of skin texture and radiance.

Who is it for: Anyone experiencing fine lines and wrinkles who is looking to help improve the appearance of skin firmness, smoothness, and overall radiance.

Why is it different: Alguronic acid is combined with retinol in this comprehensive antiaging formulation to help improve the appearance of skin firmness while minimizing the appearance of fine lines and wrinkles.

Rated 5 out of 5 by Algenist rocks I have yet to meet an Algenist product that I didn't love. Their product deliver as promised and never irritate the skin. I have tried a lot of brands over the years but rarely wanted to stick with one in particular until I tried Algenist. Love it! 10-17-15
Rated 5 out of 5 by Love this--but where did the deluxe 2 oz size go? I love this product. I started using it on January 1st (I am 33 years old and made a New Years Resolution for better skin!) with the expectation that I would not be seeing results right away. I have quite a bit of sun damage from tanning beds in my teens & twenties (ugh!), and I've always battled with acne and acne scarring. Although a round of Accutane took care of most of my acne woes 10 years ago, it also zapped all the oil in my skin and as most of us know...dry skin ages much, much, much faster. My skin is also super sensitive has a hard time tolerating prescription-strength retinoids. I turn into a bright red, painful, stinging-faced, flakey skin mess when using them. But I also know that studies show that retinoids are the best at reversing signs of sun damage and aging, so I decided this time around to take babysteps back into using prescription-strength retinoids by introducing an OTC retinol first...to get my sensitive skin used to them first, so to speak. A mild retinol is better than no retnoid at all, right? I did some research and settled on Algenist's Retinol Firming Serum mostly because of its glowing reviews around the internet and the fact that it has both a retinol and some peptides for firming, too. The first few months have been a bit bumpy for me, literally--retinols can cause break outs when you first use them since your skin is "purging", so I was well-prepared for that. (Sidenote: I read several reviews on the internet of people giving this product one star because it "caused breakouts" but retinols do that! That means they are working! The breakouts only last a little while, you just have to keep using the product and get through it. Most retinols will likely cause breakouts in the beginning, just keep that in mind.) Now that I'm about 9 weeks in, I'm finally seeing some good results! The break outs have cleared and my skin looks much clearer/brighter/smoother and more even. Retinols can take 6 months to a full year to show results, and so if I'm seeing results like this now...I can't wait to see what my skin looks like a few months down the road! That being said--QVC had a deluxe 2 ounce size that I ordered because I've found I go through 1 ounce of it every month, and it's expensive. The 2 ounce was a little bit more economical and awesome, but I notice it's no longer available to purchase here. Please bring that size back, QVC! It's the reason why I purchased this product through you, and now I'm forced to look elsewhere to buy it. :( 03-09-15
Rated 5 out of 5 by Subtle at first,but Definite As a teenager and in 30's-40's skin great until years of not using sunscreen caught up. Into 50's and now early 60's skin looking dry, tired, no deep wrinkles but they are there, and needed help. Had used some drugstore brands but not any help. Bought this as a duo with neck firming cream first of Nov. Noticed results in neck area in about 2 weeks, skin firmer, softer, lines less. I thought OK, good. Using 4-5 times a week. Next, 6 weeks gone by, in front of mirror applying moisturizer and suddenly realized skin more supple, resilient, it bounced "back" when I rubbed it. Lines less, not gone, but better. Over the next 2 weeks I had lunch and appointments with friends/clients that i had not seen in a month and another 6 months. First comments were did I get a new haircut/color, makeup etc. Didn't tell new skin care but the compliments were that I looked great! Friend said my skin was "glowing"!So, now on auto delivery and use it Every Day. Ordering Serum concentrate and eye balm next! 02-16-14
Rated 5 out of 5 by algenistfirming retinol serumworks great I am 57 and find that it works well on skin texture and noticed a difference in fine and deep lines don't cocktail with other product and use a moisturizer like Dr dense 02-15-14
Rated 5 out of 5 by Love this line! Love the entire Algenist line! I am 40 this year and have become obsessed with keeping my face as wrinkle free as possible. I use this serum twice a day on clean skin and then use the Algenist firming cream on top and all over my face and neck. This has made my fine lines less noticeable , my skin feels tighter and my pores look better. Can't wait to try more products from this line! 01-05-14
Rated 1 out of 5 by Not recommended Why would a company add fragrance to a product like this? Perfumes and colognes have alcohol in them. Very irritating to your skin. Besides that it is not a nice smell and lasts forever. Please algenist - remove this scent. I have to return it because it honestly upsets my stomach after 10 minutes. 11-02-13
Rated 5 out of 5 by Great product This works well. My only complaint is packaging can't tell how much is left. Know retinol shouldn't be exposed to light but wish they could do something so you can tell how much is left. 11-02-13
Rated 1 out of 5 by Disappointed!! I used this morning and night for 6 weeks with absolutely no improvement in the firmness of my skin to show for it. The only thing I can say positive about the product is that it is light and feels good on your skin. I'm very disappointed! Cancelled my auto-ship. What a waste of time and money!! 10-16-13
