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.

Safeguarding Squalene: Lemon Myrtle Antioxidant for Pollution Protection and Oleostasis
Squalene becomes easily oxidized when exposed to pollution and UV radiation, which promotes skin inflammation, the production of poor-quality sebum, comedogenesis and wrinkling. Lemon myrtle leaf extract neutralizes squalene oxidation and can protect all ethnic skin types from environmentally induced oily skin, restoring oleostasis.

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.
