5% Lactic Acid Serum

Smooth, soften, and renew your skin with the Nine Less 5% Lactic Acid Serum.

This gentle resurfacing treatment uses 5% lactic acid (one of the mildest AHAs) to exfoliate dead skin cells, refine uneven texture, and restore luminosity without irritation. Its hydrating texture helps maintain moisture while it works, leaving skin baby-soft, brighter, and more even day by day. The addition of peptides helps to maintain skin elasticity 

Formulated for daily or frequent use, this serum helps improve dullness, rough patches, and early signs of congestion while supporting a healthier, smoother skin barrier. With continued use, skin looks more refined and feels super soft with a fresh, natural glow.

This is Level 2: Gentle Exfoliation according to Nine Less's rating system. Can be used daily but start out every second day or less if you have sensitive skin.

30ml

What it does: Gently exfoliates, smooths uneven texture, boosts radiance, and hydrates while supporting the skin barrier.

Who it’s for: Perfect for dull, textured, or dry skin, beginners to chemical exfoliation, and anyone looking for a mild yet effective AHA serum that delivers renewed smoothness with zero harshness.
