Rated 5 out of 5 by from Algenist concentrated reconstructing serum I have used this product before and I love it. Unfortunately I received a duplicate order and product was damaged. It was not well sealed and product was overflowing in the box. Too bad since is such a waste!

Rated 5 out of 5 by from Lifting And Lightweight I am 49 with sagging jowls, neck and eye hollows with dark circles. I haven’t found a routine that works well enough for me that I stick with it daily, especially in the very hot, humid Summer months. Bought this in a kit - love it! I could feel it lifting my face almost immediately after use. Very lightweight, absorbs within a few minutes. No clogging pores at all even in high humidity. Love it so much that I have already reordered on auto delivery. Love this product!

Rated 2 out of 5 by from Worst purchase ever! This serum has so disappointed me. It wasn’t cheap and it does absolutely NOTHING! Unfortunately, when you buy a skin product you can only tell if it works by using it and this purchase is long past it’s return date.

Rated 1 out of 5 by from Not that great Serum is light, doesn't have a pleasant smell. I am near sixty and have nice skin that is just beginning to show a few wrinkles. This product did not help minimize fine wrinkles nor keep my face moisturized for the day.

Rated 2 out of 5 by from Nice smell I have not experienced any changes in my skin especially after all the hype on this product. I am 65 years old, so maybe this is for younger skin. I have had the same results without having to spend so much money
