I have been using this serum for a couple of weeks. While it does seem to smoothen out the skin gradually, in no way do I find this serum hydrating. Just the opposite: My skin feels tight, and not supple. I wind up layering another moisturizing cream over this product. I have found that the surface of my skin is improving, in that fine lines are not as noticeable, but the serum is just not hydrating, at least for me.
I have used this product daily for bout 4 years. My skin looks fabulous for 69 years of age. Most people think I am am in my late 40's which make me feel great.It seems to tighten and hydrate my skin.But it is really pricy.
