What Magnesium Silicate is & what it does

A mineral powder used to absorb oil, add bulk, and give a soft matte feel. It improves the texture of powders.

Is Magnesium Silicate safe?

Magnesium Silicate is a mineral-based powder considered safe for topical cosmetic use, where it is valued as an absorbent and bulking agent. It is used in many face and body products. Inhalation of loose powders is best avoided, so it is mainly a concern in handling rather than normal use.

What does Magnesium Silicate do in skincare?

Magnesium Silicate works as an absorbent, anti-caking, and bulking agent, helping to control oil and give products a smooth, mattifying feel. In sunscreens and powders it improves texture and application. It does not provide active skincare benefits on its own.

Is Magnesium Silicate natural or synthetic?

Magnesium Silicate can occur as a natural mineral and can also be produced synthetically for cosmetic use. The synthetic grade is made to consistent purity standards for formulation. Both forms are the same basic magnesium-silicate compound.
