Magnesium Myristate

Magnesium myristate is a mineral salt derived from magnesium and myristic acid (a saturated fatty acid). In skincare products, it functions as a multitasking ingredient that helps formulations maintain their intended texture and appearance.This ingredient works primarily as an anticaking agent, helping to prevent powder formulations from clumping, whilst also contributing to opacity and viscosity control in liquid and cream-based products. It is found in roughly 0.9% of skincare products, typically in powder formulations and occasionally in serums or creams where texture stabilisation is ne…

Magnesium myristate works at a formulation level rather than directly on skin cells. As an anticaking agent, its molecular structure allows it to absorb moisture and prevent powder particles from bonding together, which would otherwise cause clumping during storage or use.In liquid formulations, it helps control viscosity—essentially making products thicker or thinner as intended—and can provide opacity without the addition of pigments or opacifying agents. This means the ingredient is largely a behind-the-scenes component that optimises product performance rather than delivering active ski…

Magnesium myristate is a formulation ingredient rather than an active treatment, so you need not adjust how you use products containing it. It works silently within the formula to ensure consistent texture and performance. If using powder formulations, ensure they remain dry and are applied with appropriate tools to maintain efficacy.

Magnesium myristate is generally well-tolerated and widely approved for use in cosmetics across major regulatory bodies. No specific cautions are commonly reported for typical skincare concentrations.
