# Magnesium and collagen peptide

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

Keep them apart

Use them at different times of day, applying the [magnesium](https://lovi.care/skincare/fr/ingredients/magnesium) first and the peptides later, because mixing them makes the peptides less effective. Unchelated metal ions like magnesium can bind to peptides and stop them from working properly on your skin. To fix this, you can put more time between using the two products or use a product that already contains a stabilizer like EDTA.

## Questions and answers

### Can you use magnesium and collagen peptide together?

Keep [magnesium](https://lovi.care/skincare/fr/ingredients/magnesium) and [collagen peptide](https://lovi.care/skincare/fr/ingredients/collagen-peptide) apart because they may form inactive complexes that reduce biological activity. You should use them in separate routines to ensure they work properly.

### Which goes first, magnesium or collagen peptide?

Keep magnesium and collagen peptide apart in your routine because they may [complex](https://lovi.care/skincare/fr/ingredients/complex) together and reduce biological activity. Use them at separate times if you want to include both.

### Are magnesium and collagen peptide good for sensitive skin?

Magnesium and collagen peptide should be kept apart in your routine because they may form inactive complexes that reduce their biological activity. While each ingredient on its own helps improve skin hydration and barrier function, combining them directly is best avoided.
