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

Keep them apart

Use [mandelic acid](https://lovi.care/skincare/ca/ingredients/mandelic-acid) and [collagen peptide](https://lovi.care/skincare/ca/ingredients/collagen-peptide) at different times of day, applying the acid first, because the acid breaks down the peptide. The acid is too acidic for the peptide, which makes the peptide stop working and gives you less results. You can fix this by using the acid in the morning and the peptide at night, or by waiting longer between applying them.

## Questions and answers

### Can you use mandelic acid and collagen peptide together?

No, you should keep [mandelic acid](https://lovi.care/skincare/ca/ingredients/mandelic-acid) and [collagen peptide](https://lovi.care/skincare/ca/ingredients/collagen-peptide) apart in your routine. The low pH of mandelic acid destabilizes peptide bonds and may reduce their effectiveness.

### Which goes first, mandelic acid or collagen peptide?

Keep mandelic acid and collagen peptide apart in your routine, using them in separate steps or at different times of day such as AM and PM. The low pH of mandelic acid destabilizes peptide bonds and may reduce the bioactivity of collagen peptide.

### Are mandelic acid and collagen peptide good for sensitive skin?

Mandelic acid and collagen peptide should be kept apart in your routine, as low-pH acids can destabilize peptides and irritate sensitive skin. You can easily use them in separate steps or alternate routines to get the benefits of both safely.
