Your Best Face is in formulating overdrive with a new addition to its Concentrates line, the Advanced CE vitamin C serum, a new and improved Prep and now a new surge of power has been given to Antioxidants Concentrate and Hydrate B Concentrates.

Antioxidants Concentrates ($65 in the shop) has even more potency with antioxidant resveratrol. This is stuff that makes red wine so (a-hem) good for us. Before you reach for another holiday glass, note that resveratrol works even better topically. In a study on hairless mice, a single topical application of resveratrol significantly inhibited UVB-mediated phototoxicity and enhanced skin thickness.

Even more exciting is the addition of glutathione, which works in DNA synthesis and repair. What's more, it assists in the metabolism of carcinogens and toxins, while helping to maintain the functions and efficacy of other antioxidants in the formula. And these include ferulic acid, and the free radical fighters Lipochroman-6 and spin trap. Another great feature of the new formula is that it has ditched the paraben preservative for fermented radish root.

Your Best Face Hydrate B Concentrates ($45 in the shop) now has an upgraded formula with a new active that promises to firm sagging skin. Syn-Hycan stimulates hyaluronan (HA) synthesis and expression of the proteoglycans, decorin and lumican. The company that makes it tested it on women aged 56 to 65 years with loose skin on face and forearms and claims a significant decrease in sagging and double chins.

Sodium hyaluronate is a wonderful skin moisturizer. One of the reasons for sodium hyaluronate's "it" status is that, according to a review in The Archives of Dermatology, it is one of three anti-aging treatments available that are proven clinically effective. The naturally occurring and widespread component found within the extra-cellular space within bodily tissues, especially those of the face. Its water-binding and water-attracting attributes fill up the spaces between the connective fibers collagen and elastin in the dermis. Like most things, it decreases with age and, therefore, we need to top it up somehow.

There are now three forms of vitamin B: B5, B8 and B3. DMAE and parabens no longer in the formula, with preservative provided by fermented radish root.
