The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Germany.

Keep them apart

Use them at different times of day with [citric acid](https://lovi.care/skincare/de/ingredients/citric-acid) first, because acids break down this firming peptide. Citric acid makes the skin too acidic, which ruins the firming peptide and stops it from working. The shopper can use a gentler acid strength or wait longer between them.

## Questions and answers

### Can you use carnosine and citric acid together?

No, you should keep [carnosine](https://lovi.care/skincare/de/ingredients/carnosine) and [citric acid](https://lovi.care/skincare/de/ingredients/citric-acid) apart because the acidic environment of citric acid can destabilize carnosine and reduce its effectiveness. Instead, use them in separate routines or apply them at different times.

### Which goes first, carnosine or citric acid?

Keep carnosine and citric acid apart in your routine because the acidic environment of citric acid may destabilize peptides. Use them in separate routines or at different times of day.

### Are carnosine and citric acid good for sensitive skin?

Keep carnosine and citric acid apart in your routine, as the acidic environment of citric acid can destabilize carnosine and irritate sensitive skin. Lovi gives them an incompatible fit for sensitive skin.
