AHA Smoothing Serum 20% (formerly named Glycolic Serum 20%) is a non-drying Glycolic Acid/AHA for professional-strength skin smoothing to reveal softer, smoother and more even-toned skin. This powerful formula helps to reduce the look of lines and wrinkles, fade discoloration due to aging or breakouts, and clear clogged pores while smoothing the texture of the skin. The result? Beautiful skin by Renée Rouleau.

This serum does not contain alcohol, parabens, dyes or artificial fragrance. Cruelty free. This is a professional product so a little goes a long way.
