Carnosine and mandelic acid: keep them apart

Keep them apart

Use them at different times of day, applying the acid first and the peptide later, to protect your skin barrier. The strong acid breaks down the peptide and stops it from working properly on your skin. You can use a gentler acid strength or wait longer between applying them.

Questions and answers

Can you use carnosine and mandelic acid together?

No, you should keep carnosine and mandelic acid apart because the low pH of mandelic acid can destabilize carnosine and reduce its effectiveness.

Which goes first, carnosine or mandelic acid?

Keep carnosine and mandelic acid apart by using them in separate routines, because the acidic environment of mandelic acid can destabilize peptides like carnosine.

Are carnosine and mandelic acid good for sensitive skin?

Keep carnosine and mandelic acid apart in your routine, as the low pH of mandelic acid destabilizes peptides like carnosine and can irritate sensitive or barrier-compromised skin.
