Lactic acid and acetyl hexapeptide-3: keep them apart

Keep them apart

Use them at different times of day, applying lactic acid in the morning and acetyl hexapeptide-3 at night, to prevent the acid from breaking down the peptide. The acidic lactic acid clashes with the peptide, ruining its firming benefits. You can separate them into different routines or give your skin time to adjust by using them on alternate nights.
