NAC & Skin Picking
What Is NAC?
What It May Help
How NAC Works
NAC acts as a precursor to glutathione, a powerful antioxidant, and helps regulate glutamate — a brain chemical involved in compulsive urges and repetitive behaviors. By modulating glutamate activity in the brain's reward and habit pathways, NAC may help reduce the intensity of urges to pick or pull. It also has antioxidant and anti-inflammatory effects that support overall brain health.
What Does the Research Say?
Multiple clinical trials have shown NAC to be beneficial for skin picking and hair pulling disorders. A 2016 study found significant reduction in skin picking severity in adults taking NAC. Research generally supports 1200–2400 mg/day as an effective range. NAC is considered a safe, well-tolerated adjunct — not a replacement for therapy or prescribed medications.
