Mama Caution: Hi Mama! We recommend you skip this Glycolic Bright Serum for now while you are expecting or nursing. It contains Glycolic Acid (up to 8-10% in this line), an alpha-hydroxy acid (AHA) that's on our avoid list due to its exfoliating, skin-penetrating action. A Vitamin C serum is a safer way to brighten your skin during this time.
