If you use hyaluranic acid, try the skin eternals brand, I think this one is the absolute best. Another great supplement is biosil. Here's the study on it.

Also, protect the skin from the sun. Check all the various threads on sunblocks. I would go with a mineral based one personally.
HA is the only suppplement I've seen produce striking results when added to an existing multivitamin regimen. I've seen it work very well with a few other people and have used it for short periods of time myself for minor facial scar healing and it removed them for good. I used low molecular weight BioCell Collagen II HA.
Now there's a bit of a controversy about which type of HA is best (low vs. high molecular weight). Companies that sell low molecular weight HA argue that it is better absorbed while some researchers say that high molecular weight HA like sodium hyaluronate is also absorbable and closer to native human HA (what's beneath your skin).
Please look for a document named "Will The Real Hyaluronan Please Stand Up?" (JOURNAL OF APPLIED NUTRITION, VOLUME 54, NUMBER 1, 2004)
EDIT: Oh I should have added that I no longer take any kind of HA at the moment but rather use supplements that might help increase the amount of HA naturally. Like glucosamine sulfate, amino acids from whey and rice, lactoferrin (whey), magnesium (citrate or chelates) and vit A. I think they work for me.
I Try to keep my digestive system healthy too because the human GI system is a breeding ground for free radical formation and that's bad for HA.
