Offering gentle – yet extraordinary – exfoliation with lactic acid (an alpha hydroxy acid) this lightweight serum stimulates cell regeneration to reduce pigmentation, diminish acne scars and age spots and improve overall skin texture. Don’t be perturbed by the irritation often associated with acid use – The Ordinary’s Lactic Acid 5% + HA 2% contains purified Tasmanian pepperberry to reduce signs of inflammation and soothe the sensitivity sometimes caused by exfoliation. Also enhanced with heroic hydrating ingredient hyaluronic acid, this super-charged serum strengthens the lipid barrier to improve the skin’s ability to attract and retain moisture.
