Never layer Glycolic Acid and PanOxyl on the same night. Both are strong actives, and combining them can damage your skin barrier and cause excessive peeling and irritation.

PanOxyl will bleach towels, pillowcases, and clothes. Use white fabrics where it will touch, or rinse very thoroughly.

If you're new to either active, start with PanOxyl every other night before adding glycolic acid into the rotation.
