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

Keep them apart

Use them at different times of day, applying the acid first and the peptide later, because the acid is too harsh for the peptide. The strong acid breaks down the peptide and stops it from working properly. You can easily fix this by using the acid in the morning and the peptide at night.

## Questions and answers

### Can you use aha blend glycolic and citric acids and hexapeptide-9 together?

No, you should keep [aha blend glycolic and citric acids](https://lovi.care/skincare/ingredients/aha-blend-glycolic-and-citric-acids) and [hexapeptide-9](https://lovi.care/skincare/ingredients/hexapeptide-9) apart because the low pH of the acids can break down the peptide bonds and reduce their effectiveness. Use them in separate steps or routines, such as AM and PM separation.

### Which goes first, aha blend glycolic and citric acids or hexapeptide-9?

Keep aha blend glycolic and citric acids and hexapeptide-9 apart because the low pH of acids can destabilize peptides and reduce their bioactivity. Use these ingredients in separate steps or routines, such as AM and PM separation.

### Are aha blend glycolic and citric acids and hexapeptide-9 good for sensitive skin?

AHA blend glycolic and citric acids and hexapeptide-9 should be kept apart, especially for sensitive skin. Combining them in the same routine may destabilize peptide bonds and reduce bioactivity due to the low pH of the acids.
