What it is
This ingredient is obtained from plum and subjected to hydrolysis, which breaks larger constituents into smaller, more soluble fragments such as peptides and sugars. Plum is a source of polyphenols and other antioxidant compounds, and the hydrolyzed extract is used to condition the skin and improve a formula's sensory feel. In sunscreens it serves as a supporting botanical rather than as a UV filter.
Safety & warnings
Hydrolyzed plum extract is generally well tolerated at the levels used in cosmetics. As with any botanical, sensitization is possible in susceptible individuals; patch testing is reasonable for those with known stone-fruit or plant sensitivities. It is not associated with comedogenicity.
Origin & sourcing
Plant-derived, sourced from plum (Prunus domestica) and then hydrolyzed to reduce molecular weight.
