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 by applying [mandelic acid](https://lovi.care/skincare/ingredients/mandelic-acid) in the morning and [peptide-rich plasma](https://lovi.care/skincare/ingredients/peptide-rich-plasma) at night, because acids ruin peptide strength. Mixing them makes the peptides less effective and wastes the benefits of the plasma. The shopper can change to applying them in separate routines or waiting longer between steps.

## Questions and answers

### Can you use mandelic acid and peptide-rich plasma together?

Keep [mandelic acid](https://lovi.care/skincare/ingredients/mandelic-acid) and [peptide-rich plasma](https://lovi.care/skincare/ingredients/peptide-rich-plasma) apart because the acidic environment of mandelic acid destabilizes peptide bonds and reduces their bioactivity. Use them in separate steps or routines, such as applying one in the morning and the other at night.

### Which goes first, mandelic acid or peptide-rich plasma?

Keep mandelic acid and peptide-rich plasma apart by using them in separate steps or routines such as AM and PM separation. The low pH of mandelic acid destabilizes peptide bonds and may reduce their bioactivity.

### Are mandelic acid and peptide-rich plasma good for sensitive skin?

Mandelic acid and peptide-rich plasma should be kept apart, especially on sensitive skin, because the low-pH acid destabilizes peptide bonds and reduces their bioactivity. Use them in separate steps or routines, such as AM and PM separation.
