# Collagen peptide and citric acid

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

Keep them apart

Use them at different times of day, applying the acid first and the peptides later, because mixing them together cancels out their benefits. The acid is too sour and breaks down the peptides so they cannot firm your skin. You can easily fix this by using the acid in the morning and the peptides at night.

## Questions and answers

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

No, you should keep [collagen peptide](https://lovi.care/skincare/sa/ingredients/collagen-peptide) and [citric acid](https://lovi.care/skincare/sa/ingredients/citric-acid) apart in your routine because the acidic environment can break down the peptide bonds and reduce their effectiveness. Use them in separate steps or alternate routines instead.

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

Keep collagen peptide and citric acid apart in your routine because the acidic environment of citric acid destabilizes peptide bonds. Use them in separate steps or routines, such as separating them into AM and PM.

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

Collagen peptide and citric acid should be kept apart in your routine because the acidic environment of citric acid may destabilize peptide bonds and reduce their bioactivity. Use them in separate steps or routines, such as AM and PM, to protect sensitive skin from irritation.
