Details & care
What it is: A water-based hydrator that smoothes and plumps with hyaluronic acid.
What it does: This water-based formula combines low-, medium- and high-molecular–weight hyaluronic acid molecules and a next-generation HA crosspolymer to support hydration to multiple layers of your skin. It also targets the appearance of wrinkles and textural irregularities. Plus, it uses pro-vitamin B5 to enhance hydration at the outer layers, resulting in smoother, plumper skin.
Clinical results:
In a clinical study of 34 subjects applying product twice a day for 4 weeks:
- Boosts skin hydration after 1 week (with sustained results after 4 weeks)
- Strengthens skin barrier after 4 weeks
- Noticeably smoother and more supple skin after 4 weeks
- Reduced appearance of fine lines and wrinkles after 4 weeks
How to use: Apply a few drops of the serum to the face in the morning and evening. Use only as directed on unbroken skin.

It Really Works!
I knew it worked, but I was trying to convince my husband to start using it. He did not think it could possibly make a difference so we did a test. Twice a day we put a small drop on a spot on the back of his hand. After two days he compared them and could see a visible difference. The area where we put the drop had a healthy, taunt look and the skin was brighter when compared to the other hand. That sold him and now everyone in the house is using this product. As I said, it really works!

Underwelming and Peels
It may well be that I will have to have more extensive treatments to deal with my face concerns…. Had high hopes for this product… I would much rather spend less than $10 for H.Acid than the $300, but unfortunately… will not be repurchasing. No change in texture/hydration/plumpness of skin.
** do not recommend using under makeup… lots of peeling action going on, regardless of how you apply the foundation.
The squalene cleanser is amazing!

Deep hydration, leaves skin feeling full and hydra
I have dry, sensitive skin and this works just great. I can use it at any time of the day and it combines great with all my other products. Deep hydration, leaves skin feeling full and hydrated.

Pls bring back the 2 oz bottle. NOT only is it more expensive now but you only sell it on 1 oz. Size
It's a good product. I JUST WANT IT THE 2 OZ. SIZE. Thanks

Can’t get it to work.
I really want this to work but when I use it and then apply moisturiser, the moisturiser rolls off my skin. Any ideas what I’m doing wrong? I’ve tried it several times and this always happens.
