Copper peptide and protease: keep them apart

Keep them apart

Use them at different times of day with copper peptides in the morning and protease at night, because they break each other down. Protease enzymes break down the bonds of copper peptides, making both ingredients completely useless on your skin. You can easily fix this by using one in your morning routine and the other at night.
