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 [lactic acid](https://lovi.care/skincare/ingredients/lactic-acid) and [bio-placenta peptides](https://lovi.care/skincare/ingredients/bio-placenta-peptides) at different times of day, applying the lactic acid in the morning and the peptides at night, because acid breaks down the peptide bonds. Mixing them makes the anti-aging peptides lose their power and stops them from smoothing your skin. You can easily fix this by using one in the morning and the other at night.

## Questions and answers

### Can you use bio-placenta peptides and lactic acid together?

No, you should keep [bio-placenta peptides](https://lovi.care/skincare/ingredients/bio-placenta-peptides) and [lactic acid](https://lovi.care/skincare/ingredients/lactic-acid) apart because the acidic environment destabilizes peptide bonds and reduces bioactivity. Use them in separate steps or routines, such as AM and PM separation.

### Which goes first, bio-placenta peptides or lactic acid?

Keep bio-placenta peptides and lactic acid apart by using them in separate routines, such as AM and PM, because the low pH of lactic acid can destabilize peptide bonds and reduce their effectiveness.

### Are bio-placenta peptides and lactic acid good for sensitive skin?

No, you should keep bio-placenta peptides and lactic acid apart in your routine because the acidic environment may destabilize the peptide bonds and reduce their bioactivity. Use them in separate steps or routines, such as AM and PM, to protect sensitive skin.
