Fenchem research shows low molecular weight HA is more effective
By Simon Pitman, 04-Feb-2009

China-based ingredients provider Fenchem says the anti-aging ingredient hyaluronic acid (HA) is more effective at low molecular weight (LMW).

The company says it conducted in vitro studies on LMW HA to determine the penetration capacity and water holding ability compared with conventional ingredients of a higher molecular weight.

Fenchem says the results showed that the LMW HA showed clear signs of penetrating the skin more easily and also has a higher water retaining capacity, qualities that give greater anti-aging efficacy.
