What Is Sphagnum Squarrosum Extract?
Sphagnum squarrosum extract is derived from a species of moss that has been used in traditional skincare for centuries, particularly in treating various skin conditions. The extract is obtained through water-ethanol processing, which captures the plant's active compounds.
In formulations, this ingredient functions primarily as a skin conditioner, working to support the skin's natural functions and maintain its condition. Moss extracts are increasingly being studied for their potential benefits in cosmetic applications, though research into this specific species remains relatively limited.
How It Works
The extract works through its antioxidant compounds, which help neutralise free radicals that can damage skin cells. Research indicates it may also influence the expression of genes involved in key skin functions, including tyrosinase (which affects pigmentation) and enzymes responsible for maintaining skin structure.
The precise mechanisms are still being investigated, but the traditional use of moss species for skin support suggests multiple pathways of benefit may be at work.
Clinical Evidence & References
In vitro studies on sphagnum moss extracts have shown antioxidant properties and effects on gene expression in human dermal fibroblasts. Research has demonstrated inhibition of tyrosinase gene expression and general antioxidant activity, which are promising findings for skin health support.
However, human clinical studies on this specific extract are limited. Most evidence comes from laboratory research rather than trials on living skin, so claims about real-world efficacy should be considered preliminary. More robust human studies would help clarify its practical benefits in skincare formulations.
How to Use
This ingredient is typically found in formulations designed to support overall skin health rather than target specific concerns. Use as directed within your skincare routine—it's generally suitable for daily use as part of serums, toners, or moisturisers.
