🔬 The Science

Acacia mearnsii bark extract is rich in polyphenols—plant compounds known for various biological activities. The extract’s main active ingredients are proanthocyanidins, which are polymers made up of smaller units called 5-deoxycatechin. Research published in 2016 identified that #1: the extract demonstrates alpha-amylase inhibitory activity, with the most potent fractions containing specific types of proanthocyanidin structures (those with catechol-type B-rings rather than pyrogallol-type B-rings). This was confirmed through spectroscopic analysis that detected pyrocatechol compounds only in the most active fractions (peer-reviewed journal, 2016). Beyond the polyphenols, #2: the extract also contains (+)-pinitol as a major component at levels comparable to sucrose, a naturally occurring polyol that appears alongside the primary active compounds (peer-reviewed journal, 2016).

The inhibitory activity mentioned relates to the enzyme alpha-amylase, which breaks down starches in digestion—though the research abstract focuses on characterizing the extract’s chemical composition and enzymatic effects rather than describing cosmetic or skincare applications specifically.
