Last week, one of our skincare savvy customers asked if the hyaluronic acid we use in RENEW is unique in some way. He remarked that other hyaluronic acid serums report to cause inflammation, yet ours never does and furthermore RENEW provides his skin with unparalleled hydration. Why?
As with other ingredients, there is tremendous variability among HA products. Raw material source, production process, purity and molecular size all actively affect ingredient performance.
The most distinctive variable is molecular size. Because hyaluronic acid is a humectant that can draw 1000 times its own weight in moisture, large molecule HA promotes the appearance of hydrated skin as it sits on the surface. While large HA can create a protective film, if in too high a concentration, that HA can potentially draw out moisture from deeper layers of the skin, ultimately causing dehydration. To avoid this we use a low molecular weight hydrolyzed sodium hyaluronate that can effectively penetrate the skin. Studies show that this HA continues to penetrate the skin 24 hours after application and once absorbed it has the ability to
REDUCE SKIN WRINKLES
ENHANCE SKIN ELASTICITY
STRENGTHEN SKIN BARRIER
SCAVENGE REACTIVE OXYGEN FREE RADICALS
REPAIR SKIN CELLS DAMAGED BY UV RADIATION
As per the potential for low molecular weight HA to cause inflammation, that theory is not universally accepted. While articles published in the past have said it may be inflammatory, these studies were primarily conducted on wounds, not intact skin. With that said, inflammation is a protective reaction intended to eliminate the initial cause of cell injury, and clear out necrotic cells. In short, some inflammation is necessary to promote proper healing. Nevertheless studies of our particular HA ingredient do not suggest demonstrate an inflammatory response.
Beyond use of quality single ingredients, our formulation philosophy relies on the synergy of ingredients to produce comprehensive results.
When combined with the other anti-inflammatory, hydrating, deeply nourishing ingredients in RENEW serum, REVIVE eye emulsion and REFRESH mineral mist, our HA will keep your skin plump, moisturized and resilient.
