AAA+ products
I am a big fan of all Algenist products, they are just good for your skin. I had never used the liquid collagen serum. After a couple weeks I really started to see the difference in my skin. It is plumper, softer and those tiny fine lines have almost disappeared. I usually mix up my skin care products but using all Algenist together has really changed my complexion for the better.

Great product - Great price
I have used Algenist Genius Serum for years and it does takes years off. I am so happy that Amazon is carrying the Super Size bottle which is almost never available at the Algenist website. I love the great price too. Thank you

This is a very highly recommended product for women
Oh, this product works so good. It is a little bit pricey, but when I have the bunny, I love to buy this liquid collagen and believe me, it works wonders

Great serum for aging skin. Day/night goes on light
Love the Algenist line. In contrast to their overnight collagen mask, which goes on kinda thick and greasy until you really massage it in, this serum is light (in comparison) and your skin will drink it up!

Love it!
⭐⭐⭐⭐⭐ My Honest Review of Liquid Collagen — “Liquid Gold!” I absolutely love this liquid collagen and I call it my liquid gold! I’m 62 years old, and I’ve definitely noticed the difference it makes. Friends and strangers alike are often surprised when they find out my age, and more than once someone has asked me what my secret is. This product has become one of those little beauty staples I don’t want to be without. So when I find it on sale, I grab it!

Good product although pump Does not Work. $25.00 is it worth it?
I love the product but the pump does not work on the bottle, so I'l not sure if I'm using the right amount?

Seems too expensive for the amount you get. The dropper is shocking as it just doesn’t work and a lot of the product just stays inside and it also doesn’t get the product out of the bottom when you’re running out. The actually product itself I haven’t seen a change after 2 months of use but it does feel nice and smooth and not sticky or greasy on the skin. Probably won’t buy again due to the price and no visible change to my face.

Definitely improves fine lines, this is my new go to serum! Could see a difference in a few days. Love it!

It’s my own fault for not reading the size, but I assumed this would be a similar size to the Obagi Hydrodrops, which are brilliant but expensive. At this size, I may as well have spent the extra!
