Rated 4.1 out of 5 by 29 reviewers.
Rated 5 out of 5 by Great product I have been using these products for 5 months. First the product lasts for 5 months. I am happy to report that forehead wrinkles are reduced. Overall skin texture and firmness is improved. Baggy upper eyelids are almost gone. Love these products! They deliver. 07-23-15
Rated 5 out of 5 by Great Product I bought this product after my daughter (a microbiologist PhD) recommended it. She told me this was scientifically developed and she has been using for a couple months now and loves it. I decided to give it a try and so far I really like it. When I put it on first thing in the morning, the lines around my eyes disappear. I use it twice a day as recommended and I'm very happy with this product. I plan on buying the eye serum next. 01-13-14
Rated 4 out of 5 by Great Product I purchased this duo when it was a TSV. I have previously used Dr. Denese's line for years along with Hope in a Jar. I still use these products intermittently Because they are excellent & I have always received compliments on my skin, at 60yrs. of age I am always told that I look like I'm in my early 50's, needless to say I love that. I also feel that after using any one product for awhile you have to rotate to other products because your skin just gets used to the product & is not as effective. I stumbled upon Algenerist & have been using it for months now & have received many compliments on my skin. it really is soft, smooth, & glowing. The only complaint I have is that of many others. This duo does not provide enough serum to last I belive 90 days or whatever the auto ship is. I have half a jar of firming cream & next to nothing with the serum. I hope Algenerist can correct what seems to be a problem or I will consider trying other products or going back to the ones that worked before. I never had this happen to me with any of Dr, Denese's products or Philosophy either. I wouldn't mind paying a few extra dollars to Algenerist to get the correct size of serum although it seems to be a mistake on their part. It is for that reason I am giving this product four stars instead of five. I considered giving it three stars but couldn't because it is an excellent product. 10-23-13
Rated 2 out of 5 by Disappointed! I've been using these products and the eye cream for several months and have seen no difference in my skin. The products are good enough to finish but not reorder. If you really want to see a difference, try Kate Somerville. 10-04-13
Rated 5 out of 5 by LUV LUV LUV!!! I am a self-confessed beauty product junkie and have probably tried every commercial product on the market if it promised anti-aging benefits. Plus, as a medical professional, I also have access to the best prescription skin care products available. But I have to say that this stuff is the BOMB!! I am so glad I got it on auto delivery although, like others have commented, the serum doesn't last anywhere close to 90 days-- they really have to make that a larger size-- and I only use the stuff in the morning. I am 59 (+ 1/2) yrs old, have had a life-time of excessive sun exposure and, even though I was lucky my skin didn't look much worse, I was really looking for some improvement. I've been using Algenist now for 3 months and what a difference!! The lines and wrinkles really have almost disappeared, age spots on my jawline have faded, and my skin looks absolutely luminous. I honestly look 15 yrs younger and am thrilled. Now, I confess, I put the serum on in the morning and then use the LightStim to kind of bake it in. Not really sure if that makes a real difference or not. But I am extremely pleased with this product and how it's made a difference in making my skin look yrs younger. I won't be without it...in fact, I ran out of the serum while in Rome and, luckily, Sephora carried it so I was safe. 09-03-13
Rated 4 out of 5 by Wonderful Product This Algenist duo is the greatest. Diminished fine lines and wrinkles in a very short time. Only drawback is that the serum does not last anywhere near 90 days! Highly recommend they increase the size of the serum. I have been out of serum over 2 weeks and still have 1/2 jar of cream. P.S. I am 71 years old. Wish everyone would tell their age to give a better idea on results for different age groups. Richi 08-27-13
Rated 5 out of 5 by What Wrinkles What Large Pores After one day of using this product my wrinkles and very large pores were gone gone gone. I have tried more products than I would like to admit, most made me breakout and the pores never got better. These products worked for me, I look 10 years younger as all my friends tell me. I am glad that I am on auto delivery. Thanks for a great product 08-23-13
