Lactic acid and tri-ceramide complex: keep them apart

Keep them apart

Use them at different times of day, applying lactic acid first, because mixing them together can weaken your skin barrier and reduce their effectiveness. Lactic acid is too acidic and can clash with the ceramides, making your skin feel irritated and dry instead of smooth and repaired. You can change this by using a gentler strength of acid or waiting longer between steps.
