Zinc sulfate and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Use them at different times of day, applying the zinc in the morning and the peptide at night, because mixing them makes the peptide inactive. Zinc sulfate binds to palmitoyl pentapeptide-4 and stops it from working properly on your skin. To fix this, you can space them out into separate routines or use products that already include stabilizing ingredients.
