The Ordinary Lactic Acid 5% + HA (30ml) A mildly-exfoliating serum to target uneven tone, textural irregularities, and fine lines. Offering a very gentle exfoliation at a 5% concentration, this lightweight serum works to improve skin texture, reducing pigmentation caused by acne scars and age spots by stimulating cell regeneration.
