Copper peptide and citric acid: keep them apart

Keep them apart

Use them at different times of day, applying the citric acid first and the copper peptide later, because acids break down peptides. Citric acid makes the skin too acidic, which ruins the peptide's ability to firm and smooth your skin. To fix this, simply use your acid in the morning and your peptide at night, or wait a few minutes between them.

Questions and answers

Can you use copper peptide and citric acid together?

No, copper peptide and citric acid should be kept apart in your routine because the acidic environment can break down the peptide bonds and reduce their effectiveness. Use them in separate steps or alternate routines, such as applying one in the morning and the other at night.

Which goes first, copper peptide or citric acid?

Keep copper peptide and citric acid apart in your routine because the acidic environment destabilizes peptide bonds and reduces their bioactivity. Use acids in a separate step or routine, such as AM and PM separation.

Are copper peptide and citric acid good for sensitive skin?

No, copper peptide and citric acid should be kept apart in your routine because the acidic environment of citric acid may destabilize and reduce the activity of copper peptide. Use them in separate steps or routines, such as AM and PM, to protect sensitive skin from irritation.
