Yes, I use the HA even in the eye area, but with caution! I've been at it for only a week or so, but will let everyone know of any scar improvement...still, I'm amazed at how much better my skin looks in general with HA.
The article about the elderly people in that japanese village eating HA in yam-like vegetables mentioned an older woman with incredible skin. Of course, they've been eating this all their lives. So I'm trying to catch up! I noticed a big change by taking it internally for other non-related issues; many take it for Arthritis so I think it will turn out to have many applications.
