Maximum Hydration Hyaluronic Acid Serum 1 fl. oz.

I am in my mid-40's and have sensitive skin. I started using this about 2 weeks ago and it is working great! I put it under my moisturizer and my skin already feels more hydrated and is glowing. I love that it's a clean product with no perfumes. I will purchase this again when I run out!

I am amazed how quickly this has reduced some pretty deep lines on my face. I use it as a base serum and my skin has never felt so nourished and soft. I work in a health store and highly recommend this product; it is much better priced than other local competitors. The only bemol is the lid doesn't seem to secure properly, no matter how carefully twisted. Twice when traveling it has partially emptied into my bag. The top has not come off, just loosened and leaked, what a waste! That said, if you keep it on the shelf, this is a quality 5 star product.

I'm an avid user of HA serums, and though I like to try different brands and different types, I always come back to this one. I typically pay twice as much and get a similar or less effective product. For anyone looking to add an HA serum to your morning ritual, start with this. Earth Science does a good job. I think this is the most natural of the products I have used. You can tell it's pure and gentle from the way it feels on your skin. I give it 4 instead of 5 stars just because of my inability to work the applicator. It has a fancy dropper, but I always end-up squeezing out too much.

I've tried many brands of hyaluronic acid, and I think this is the one! Liquid is soft and smooth and seeps into the skin without any lasting residues. Love the packaging, and my skin loves it, too. Thank you, Earth Science!
