What it is
Prunus domestica seed extract is a plant-derived ingredient obtained from the seeds of the European plum. In sunscreens and other leave-on formulas it is typically present at low levels as a conditioning and antioxidant additive rather than as a functional sunscreen agent. Its contribution is supportive, complementing the active filters and base emollients.
Safety & warnings
Generally well tolerated as a botanical extract at the low levels typical of cosmetic use. As with any plant-derived seed material, individuals with known sensitivities to related stone fruits or tree nuts may wish to use caution, and patch testing is reasonable for reactive skin.
Origin & sourcing
Natural, derived from the seeds (kernels) of the European plum, Prunus domestica.
Questions everyone asks
Is plum seed extract a sunscreen filter?
No. It is a botanical skin-conditioning and antioxidant additive, not a UV filter; the sun protection comes from the product's listed active filters.
What does it do in a sunscreen?
It acts as a supportive conditioning and antioxidant ingredient, contributing to the feel and stability of the formula rather than to UV protection itself.
