What it is
Magnolol is a naturally occurring biphenolic compound isolated from the bark of magnolia trees, where it occurs alongside the related molecule honokiol. In cosmetics it is valued for antioxidant behavior and as a skin-conditioning agent that can help support a calm-feeling complexion. It is typically used at low concentrations as part of a botanical or soothing system rather than as a bulk ingredient.
Safety & warnings
Magnolol is generally well tolerated at the low levels used in cosmetics. As with many concentrated botanical actives, sensitive individuals may rarely experience irritation, so patch testing is reasonable for reactive skin.
Origin & sourcing
Naturally derived; isolated from the bark of magnolia species (notably Magnolia officinalis).
History
Magnolia bark has a long record of use in traditional East Asian herbal practice, and magnolol was later characterized as one of its principal bioactive constituents and adopted in cosmetic formulations.
