The Ordinary Lactic Acid 10% + HA is a high strength exfoliating serum designed to smooth skin, improve texture, and reduce dullness while being suitable for dry skin.

1. Anti Irritant: Formulated with Tasmanian pepperberry extract to minimize irritation and sensitivity often associated with acid exfoliation.
