Hexapeptide and citric acid: keep them apart

Keep them apart

Use them at different times of day, applying the acid first and the peptide later, because mixing them makes the peptide lose its power. The acid is too sour for the peptide and breaks its helpful bonds, which means you might not see the firming results you want. You can fix this by using them in separate routines, such as one in the morning and one at night.

Questions and answers

Can you use hexapeptide and citric acid together?

Which goes first, hexapeptide or citric acid?

Keep hexapeptide and citric acid apart by using them in separate steps or routines, such as applying one in the morning and the other at night. The acidic environment of citric acid can destabilize hexapeptide bonds and reduce its effectiveness when combined in the same routine.

Are hexapeptide and citric acid good for sensitive skin?

Keep hexapeptide and citric acid apart in your routine because the low pH of citric acid can destabilize hexapeptide and reduce its effectiveness. For sensitive skin, it is best to use these ingredients in separate steps or routines, such as using one in the morning and the other at night.
