MAGNESIUM OXIDE

Description

Magnesium oxide is a versatile inorganic compound with significant applications in skincare formulations. This white, odorless powder is composed of magnesium and oxygen, forming a stable, non-toxic substance. In skincare products, magnesium oxide serves multiple functions, primarily as an opacifying agent and pH adjuster.

As an opacifier, magnesium oxide helps to create a uniform, opaque appearance in creams and lotions, enhancing their aesthetic appeal. Its ability to absorb excess oils makes it valuable in mattifying products and those designed for oily skin types. Magnesium oxide also acts as a mild abrasive, contributing to gentle exfoliation when incorporated into scrubs or cleansers.

The compound's alkaline nature allows it to function as a pH adjuster, helping to stabilize formulations and maintain optimal skin compatibility. Additionally, magnesium oxide exhibits antimicrobial properties, potentially aiding in the preservation of skincare products. Some research suggests it may have anti-inflammatory effects, though more studies are needed to confirm its efficacy in this regard.

While generally considered safe for topical use, high concentrations of magnesium oxide can be drying, so formulators must carefully balance its inclusion in skincare products.
