Improved skin texture & glow

Great serum that improves skin texture and feels light. Is not heavy or sticky and saw improvement right away.

Luxurious feel even for sensitive skin!

It is not greasy. It goes on very smoothly.  I noticed my skin feels smooth and soft when I've used it. It didn't take long for me to feel like my skin was having a positive response to it - kind of like "rejuvinated" and "bright"....and it looked like my skin tone evened out. I mean, it's not a "miracle worker" but I have liked the results so far.

Hyaluronic Acid Magic for 64 year old!

This product is amazing! I put a few drops on my damp face after washing in the morning before applying my makeup. I live in the cold dry Winters had been doing a number on my skin. This product helps retain the moisture and after makeup my skin looks luminous instead of dried out!  It is excellent! I highly recommend it!
