Magnesium
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. When adding magnesium to your daily regimen, simply apply it apart from bio-placenta peptides, hexapeptide, and acetyl hexapeptide-3.

What to combine magnesium with
| Ingredient | Together | How to use them |
|---|---|---|
 Bio-placenta peptides |
Keep apart | Use them at different times of day, applying the peptides in the morning and magnesium at night, because mixing them makes both less effective. Magnesium and bio-placenta peptides |
 Hexapeptide |
Keep apart | Use them at different times of day, applying the peptide serum in the morning and the magnesium at night, because they cancel each other out. Magnesium and hexapeptide |
 Acetyl hexapeptide-3 |
Keep apart | Use them at different times of day, applying the peptide first and the magnesium later, because mixing them makes the peptide less effective. Magnesium and acetyl hexapeptide-3 |
 Collagen peptide |
Keep apart | Use them at different times of day, applying the magnesium first and the peptides later, because mixing them makes the peptides less effective. Magnesium and collagen peptide |
 Copper peptide |
Keep apart | Apply them at different times of day by using copper peptide in the morning and magnesium at night, because they cancel each other out. Magnesium and copper peptide |
 Hexapeptide-9 |
Keep apart | Use them at different times of day, applying the peptide first and the magnesium later, because mixing them makes the peptide less effective. Magnesium and hexapeptide-9 |
 Peptide-rich plasma |
Keep apart | Apply them at different times of day, using the peptide product in the morning and the magnesium at night, because mixing them makes the peptides less effective. Magnesium and peptide-rich plasma |
 Triple peptide blend |
Keep apart | Apply them at different times of day, using the peptide blend in the morning and magnesium at night, to keep them apart. Magnesium and triple peptide blend |
 Palmitoyl pentapeptide-4 |
Keep apart | Use them at different times of day, applying the peptide first, because they cancel each other out when mixed. Magnesium and palmitoyl pentapeptide-4 |
 Palmitoyl tripeptide-1 |
Keep apart | Apply them at different times of day, using magnesium in the morning and peptides at night, because mixing them makes the peptides less effective. Magnesium and palmitoyl tripeptide-1 |

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 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.
