What Is Myristyl Lactate?

Myristyl lactate is a synthetic ester formed from myristic acid (a naturally occurring fatty acid) and lactic acid. It functions primarily as an emollient and skin conditioning agent, helping to soften and smooth the skin surface.

This ingredient appears in relatively few skincare formulations (roughly 0.1% of products), where it is typically used at low concentrations to enhance texture and improve how products feel on the skin.

How It Works

Myristyl lactate works primarily as an emollient, reducing water loss from the skin and creating a smooth, conditioned feel. At higher concentrations (above 3%), research suggests it may also enhance the percutaneous absorption of other ingredients by acting on the stratum corneum, the skin's outermost layer.

In most skincare products, however, concentrations are likely too low for this absorption-enhancing effect to be significant. Its primary role remains skin conditioning and texture improvement.

Clinical Evidence & References

Evidence on myristyl lactate specifically is limited. Most research examines its use as a penetration enhancer at concentrations above 3%, where studies in animal models show it can increase absorption of certain actives through the skin barrier.

In cosmetic formulations, concentrations are typically much lower, and there is little clinical data on its efficacy or behaviour at these levels in human skin. More research would be needed to clarify its benefits in typical skincare products.

How to Use

Myristyl lactate is used by formulators rather than applied directly by consumers. When present in your skincare, it will be listed in the ingredients. There are no specific usage instructions required; simply apply the product as directed.

Safety & Precautions

Myristyl lactate is generally well-tolerated. However, some users report it may contribute to congestion or worsen oily skin, though evidence for this is anecdotal rather than conclusive. Patch testing is advisable if you have acne-prone or very oily skin.
