What it is
Alpinia purpurata is a tropical ginger-family plant whose leaves yield an extract rich in polyphenolic compounds. In cosmetics it is included as a botanical additive intended to condition the skin and contribute antioxidant activity to a formula. It typically appears at low concentrations alongside other plant extracts rather than as a primary functional ingredient.
Safety & warnings
Botanical extracts from the ginger family can occasionally provoke sensitivity in individuals prone to plant allergies, though this extract is generally used at low levels. As with other plant extracts, the actual composition depends on the solvent and plant batch, so people with known botanical sensitivities may wish to patch test.
Origin & sourcing
Plant-derived; obtained from the leaves of Alpinia purpurata, a flowering ginger species native to tropical regions. The leaf material is processed into an extract, often using water or a water-glycol solvent system.
