What Is Sphagnum Magellanicum Extract?
Sphagnum Magellanicum Extract is derived from a species of moss native to South American peatlands. Mosses have been used in traditional medicine for centuries, particularly for treating skin conditions and damage, though their use in modern cosmetics remains relatively understudied compared to other botanical ingredients.
In skincare formulations, this extract functions as a skin conditioning agent, working to support the skin's natural protective functions through its biochemical composition.
How It Works
Sphagnum Magellanicum Extract appears to work primarily through its antioxidant compounds, which can neutralise free radicals that contribute to skin damage and premature ageing. Early research suggests it may also modulate the expression of enzymes involved in processes like melanin production, collagen breakdown, and moisture regulation within the skin.
These mechanisms are thought to occur at the cellular level within the dermis, where fibroblasts (the cells responsible for producing collagen and elastin) reside.
Clinical Evidence & References
In vitro studies have shown that water-ethanol extracts from Sphagnum species demonstrate antioxidant properties and can inhibit tyrosinase gene expression—an enzyme involved in melanin production. The research also indicates potential effects on genes encoding collagenase, elastase, hyaluronidase and hyaluronic acid synthase, which are important for skin elasticity and hydration.
However, these findings are from laboratory studies on isolated cells rather than human skin trials. Further research is needed to establish what these cellular effects translate to in real-world skincare use, what effective concentrations are, and whether benefits are observable in clinical settings.
How to Use
Sphagnum Magellanicum Extract is typically found in serums, moisturisers and targeted treatments. As with any new ingredient, introduce it gradually to observe how your skin responds. It can generally be used daily as part of your regular skincare routine, either morning or evening, depending on the product formulation.
