What it is
Psidium Guajava Leaf Extract is obtained from the leaves of the guava tree, which are rich in polyphenols, flavonoids, and tannins. In cosmetic formulas it is included for its antioxidant properties and to give a conditioning, lightly astringent feel to the skin. It typically appears at low concentrations alongside other plant extracts in sun care and facial products.
Safety & warnings
Botanical leaf extracts of this type are generally well tolerated at the low levels used in cosmetics. As with any plant extract, sensitive individuals may occasionally react, and the tannin content can contribute a mild astringent effect on the skin.
Origin & sourcing
Plant-derived. It is produced by extracting the dried or fresh leaves of Psidium guajava, the common guava, usually with water, glycerin, or hydroalcoholic solvents.
