What is the primary effect of magnesium carbonate on the skin?

Magnesium carbonate primarily acts as a temporary astringent and tonic for the skin. This means it helps to tighten the skin temporarily and can reduce the appearance of pores, making it useful for individuals with oily or combination skin types. The astringent properties help to absorb excess oil and control shine, while the tonic effects can stimulate the skin, promoting a healthy appearance.

In beauty therapy, these benefits make magnesium carbonate particularly suitable for products aimed at balancing oil production and improving skin texture. It is also important in formulating treatments for skin conditions where excess oil and enlarged pores are a concern.
