Glycolic Acid is a water‑soluble alpha hydroxy acid (AHA) that gently lifts away surface buildup for freshly polished, smoother‑looking skin. With the smallest AHA molecule, it refines texture, boosts visible radiance, and helps your next steps absorb more evenly. A glow‑giver for those navigating dullness and uneven texture—especially normal to combination or oily skin—while sensitive skin types should introduce it slowly.
