This is a terrific product! I've used it for 6 months now, and wouldn't want to do without it!
It is very rich, and after a week or so I saw a noticable difference in both the fine and deep lines.
I have sensitive skin, and did not have a problem with any irritation.
I found it to be mid-priced, not cheap, but a little bit goes a long way, and it WORKS.
One jar lasts about 2 months using it twice a day.
