Science
Mechanism of Action
The peel contains a complex profile of natural alpha-hydroxy acids (AHAs) that facilitate gentle desquamation by loosening the bonds between dead skin cells. Simultaneously, its high concentration of flavonoids and phenols neutralizes oxidative stress, while its natural astringent properties modulate excess sebum production and help minimize the appearance of pores.

Dusting Analysis
Because it is often used for its aromatic profile or marketing appeal, many formulations include it at 'dusting' levels. However, for leave-on products, the concentration must be strictly controlled to stay below 15 ppm of 5-methoxypsoralen to avoid phototoxicity.
The Formula
Formulation
Stability
The extract is a light-to-medium amber liquid that requires protection from direct UV exposure. Formulations must account for the presence of furocoumarins to ensure photosensitivity is not triggered.

Safety
Safety Profile
Safety is contingent on the 5-MOP content; leave-on products are capped at 15 ppm of 5-methoxypsoralen to prevent phototoxic reactions. It contains potential allergens like limonene and citral.
