Citric acid and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Apply citric acid and palmitoyl pentapeptide-4 at different times of day, using the acid in the morning and the peptide at night, because the acid ruins the peptide. The acidic ingredient breaks down the peptide bonds, making the anti-aging product totally useless on your skin. To fix this, simply use them in separate routines or wait a while between them.

Questions and answers

Which goes first, citric acid or palmitoyl pentapeptide-4?

Keep citric acid and palmitoyl pentapeptide-4 apart by using them in separate steps or routines, such as morning and night separation, because the acidic environment of citric acid may destabilize the peptide bonds and reduce bioactivity.
