# Bio-placenta peptides and citric acid

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

Keep them apart

Use them at different times of day, applying the [citric acid](https://lovi.care/skincare/ie/ingredients/citric-acid) in the morning and the [bio-placenta peptides](https://lovi.care/skincare/ie/ingredients/bio-placenta-peptides) at night, because the acid breaks down the peptides and ruins their anti-aging power. Citric acid makes your skin too acidic, which destroys the peptide proteins before they can smooth your skin and boost firmness. You can easily fix this by applying the acid and peptides in separate routines, such as morning and night, or on alternate days.

## Questions and answers

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

You should keep [bio-placenta peptides](https://lovi.care/skincare/ie/ingredients/bio-placenta-peptides) and [citric acid](https://lovi.care/skincare/ie/ingredients/citric-acid) apart because the low pH of the acid destabilizes the peptides and reduces their activity. Use them in separate steps or routines, such as applying your acid and peptides in the AM and PM respectively.

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

Keep bio-placenta peptides and citric acid apart because the acidic environment destabilizes peptide bonds and reduces bioactivity. Use the acid in a separate step or routine, such as in the morning and peptides in the evening, to protect your skin barrier.

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

No, bio-placenta peptides and citric acid should be kept apart in your routine because the acidic environment may destabilize the peptides and reduce their bioactivity. Sensitive skin especially benefits from using these ingredients in separate steps or routines, such as AM and PM, to avoid low-pH irritation.
