Lactic acid smooths texture and brightens dull skin; pricey, with fleeting glow.

A leave-on lactic acid exfoliant with a moisturizing serum texture aimed at dullness, rough texture, and fine-line concerns. It suits experienced acid users who want visible glow, though daily use can trigger peeling or acne.
