Mandelic acid and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Use them at different times of day, applying mandelic acid in the morning and palmitoyl pentapeptide-4 at night, because the acid ruins the peptide. The acid weakens the peptide and stops it from firming the skin. The shopper can separate them into different routines or wait ten minutes between steps.

Questions and answers

Can you use mandelic acid and palmitoyl pentapeptide-4 together?

No, you should keep mandelic acid and palmitoyl pentapeptide-4 apart because the low pH of mandelic acid can destabilize the peptide bonds and reduce their effectiveness. Use them in separate steps or routines, such as alternating between morning and evening applications.

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

Keep mandelic acid and palmitoyl pentapeptide-4 apart in your routine by using them in separate steps or routines, such as AM and PM separation. The low pH of mandelic acid can destabilize peptide bonds and reduce the bioactivity of palmitoyl pentapeptide-4 if they are combined directly.

Are mandelic acid and palmitoyl pentapeptide-4 good for sensitive skin?

Mandelic acid and palmitoyl pentapeptide-4 should not be combined directly in the same routine, especially for sensitive skin, because the acidic environment destabilizes peptide bonds and reduces their bioactivity.
