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

Magnesium strengthens the skin barrier, enhances hydration, reduces roughness and redness, relieves dryness and lesion severity, and visibly brightens stubborn dark spots. This gentle mineral suits almost all skin types and is most commonly formulated into soothing [serums](https://lovi.care/skincare/ca/ingredients/serum). When adding magnesium to your daily regimen, simply apply it apart from [bio-placenta peptides](https://lovi.care/skincare/ca/ingredients/bio-placenta-peptides), [hexapeptide](https://lovi.care/skincare/ca/ingredients/hexapeptide), and [acetyl hexapeptide-3](https://lovi.care/skincare/ca/ingredients/acetyl-hexapeptide-3).

## Questions and answers

### What does magnesium do for the skin?

Magnesium helps improve skin barrier function, enhances skin hydration, and reduces inflammation and roughness in dry or irritated skin. It may also help reduce melanin levels in melasma patients when used in specialized treatments.

### How do you use magnesium?

You can use magnesium at night to help improve skin hydration and barrier function. When using peptides, apply them in the morning and magnesium at night to keep them apart because mixing them makes the peptides less effective.

### Should you use magnesium in the morning or at night?

You can use magnesium at night, particularly when pairing it with peptides which should be applied in the morning to prevent them from becoming less effective. Using magnesium may also help improve skin hydration and barrier function.

### Can you use magnesium every day?

Yes, you can use magnesium every day to help improve skin barrier function, enhance hydration, and reduce inflammation. Topical magnesium is generally well-tolerated and supports overall skin health with daily application.

### Does magnesium cause purging or irritation?

Magnesium is unlikely to cause purging and helps reduce irritation and redness, while improving skin hydration and barrier function.

### Can you use magnesium with bio-placenta peptides?

No, you should keep magnesium and [bio-placenta peptides](https://lovi.care/skincare/ca/ingredients/bio-placenta-peptides) apart by using them at different times of day, applying the peptides in the morning and magnesium at night, because mixing them makes both less effective.
