Tonymoly's Plum Bum Tightening Peptide Serum is an all-over serum that deeply hydrates the skin from head to toe. Formulated with plum extract and peptides, it relieves inflammation, locks in moisture and strengthens the skin barrier. This lightweight serum absorbs quickly into the skin, leaving a light, moist finish with no stickiness. Clinical studies revealed improved skin elasticity and hydration, with participants reporting firmer, more radiant skin, visible lifting effects and high satisfaction with long-lasting hydration.
