Measuring the Antioxidant Potential of an Acai Extract
The antioxidant potential of cosmetic materials can be evaluated by several methodologies, including a commercial kit that measures total antioxidant status, as illustrated here with a commercial extract from the fruit of the açaí, a Brazilian palm tree. Applications in antiaging products are suggested.

The Photostability and Photostabilization of
trans
-Resveratrol
In this study, the effects of ultraviolet radiation (UVR) on trans-resveratrol were documented, finding that UV radiation causes it to undergo rapid and extensive photoisomerization and some photodecomposition. The antioxidant activity of trans-resveratrol is correspondingly reduced. However, in the presence of ethylhexyl methoxycrylene, a photostabilizer used in sunscreens, the effects of UV exposure on trans-resveratrol are minimized, thereby preserving its antioxidant activity and, presumably, its bioavailability.

A Compound to Increase Natural CoQ10 for Anti-aging Benefits
Oxidative stress is a major factor in skin aging, thus a topical compound was designed to increase anti-oxidant coenzyme Q10 (CoQ10) within the body. Described here are in vivo and in vitro studies assessing the compound’s antioxidant and anti-aging capabilities. Results indicate that the modulation of intracellular CoQ10 and its binding proteins appears to protect skin from oxidative damage.

Moringa Leaf Phytochemicals for Skin Benefits
This paper describes the development of a stable moringa plant concentrate comprising the extraction and identification of stable actives, via plant metabolites, and the correlation of activity through a variety of in vitro models. The resulting concentrate demonstrated direct and indirect antioxidant benefits and inhibitory action against inflammation and UV-induced MMP-1.

TechEdge--Understanding Reactive Oxygen Species
One antioxidant does not address all of the different free radicals that may be formed by an oxidative stress. Thus it is best to use a blend. In selecting antioxidants, a chemist must consider concentration and the effect of synergies or antagonists.

Comparatively Speaking: Cofactors vs. Coenzymes
Enzymes for DNA repair or Coenzyme Q10 for antioxidant and antiaging benefits have become typical ingredients in today's skin care. Here, industry expert O'Lenick illustrates the difference between cofactors and coenzymes.

Characterizing the Anti-aging Effects of
Hesperomeles heterophylla
Hook Leaf Extract
Hesperomeles heterophylla
Hook leaf extract was evaluated as described here for its application in anti-aging skin care. This traditional extract exhibited antioxidant and protective properties on the extracellular matrix due to high levels of polyphenols and flavonoids. Further, a formulation containing 0.35% extract was tested in vivo and showed promising effects on wrinkles and skin elasticity.
