I have bought this serum several times now-whenever I run out! I think I’m almost to the end of my 3rd bottle! I love it! Helps my skin feel so much more hydrated. I just wet my hands and use 1 pump of the serum and just spread all across my face and neck. Must be used with water-with wet hands or damp face-directions encourage wet hands from water and then just pump into hand and mix and apply. I love especially using at night and then once it’s dried on my face and neck, just takes 1-2 minutes to dry, then I love applying a nourishing cream on top before bed! Amazing hydration. It is a very expensive product, and sometimes hard for me to justify spending so much on it, but I love it so! So I try to make it work into my budget, and make sure I’m using the minimum required (1 pump for me) , and make it last as long as I can! Great product and love HH for their great customer service, fast shipping, beautiful packaging, and just being a trustworthy business to buy from online! Def recommend this product if you can make it work into your budget!

My skin just looks so much better in the morning when I apply it at night :-). Will continue to repurchase

Have been using this since it was first introduced by Skinmedica. I use it in conjunction with the TNS Essential serum. It is these two products that are helping me to maintain my genetically nice skin. My skin insensitive and normal to dry. I have had no adverse reactions and get compliments on my smooth skin.

It is an amazing product. I have had stubborn fine lines that this product has addressed. My dermatologist recommended this product. I would definitely buy this product again and again.

I use HA5 with Sente Dermal Repair scream. The two together works great for my super reactive skin. Only “moisturizers” that don’t break me out or make my foundation slide off my face.
