Azelaic acid and hexapeptide-9
Keep them apart
Use azelaic acid and hexapeptide-9 at different times of day, applying the acid in the morning and the peptide at night, because the acid ruins the peptide. The strong acid breaks down the peptide, making it completely useless on your skin. To fix this, you can simply use the acid in your morning routine and the peptide at night.

Questions and answers

Which goes first, azelaic acid or hexapeptide-9?
Keep azelaic acid and hexapeptide-9 apart by using them in separate steps or routines, such as AM and PM, because low-pH acids should not be combined directly with peptides.
Are azelaic acid and hexapeptide-9 good for sensitive skin?
Keep azelaic acid and hexapeptide-9 apart because low-pH acids should not be combined directly with peptides in the same routine, though they are suitable for sensitive skin when used separately.
