Science
Mechanism of Action
Peat Moss Extract exerts its effects through a complex interplay of organic compounds, vitamins, and minerals, notably humic acids and fulvic acids. These substances act as potent antioxidants, mitigating oxidative stress by reducing reactive oxygen species (ROS) and safeguarding against premature aging. Its anti-inflammatory properties calm irritated skin and reduce redness. The extract contributes to skin hydration by retaining water and reinforces the skin barrier by improving keratinocyte differentiation, increasing E-cadherins, and inhibiting sphingomyelinase activity. It also possesses mild exfoliating actions, promoting smoother texture, and supports detoxification by helping eliminate microparticles. Furthermore, it modulates cellular senescence to aid wound healing, balances the skin microbiome by promoting beneficial bacteria like *Staphylococcus epidermidis* while inhibiting *Staphylococcus aureus*, and offers mild astringent and potential UVB-protective benefits.

Key findings
- 01 Demonstrated significant anti-aging potential by promoting dermal fibroblast proliferation by 35-50% within 24 hours.
- 02 Provided a rapid soothing effect on sensitive skin, showing a 16% greater soothing effect than placebo after 1 minute and 42% after 15 minutes. It also enhanced detoxification by 16.3% compared to placebo, effectively eliminating carbon microparticle deposition.

Dusting Analysis
There is no available data to suggest that Peat Moss Extract is commonly 'dusted' or used at ineffectual concentrations for marketing purposes. Clinical studies indicate efficacy at specific, measurable concentrations.
The Formula
Formulation
Stability
Peat moss itself is naturally acidic, with a pH typically ranging from 3.0 to 4.5, although some varieties can be closer to 5.0-6.0. While specific optimal pH ranges for the extract's stability in cosmetic formulations are not explicitly defined, the extract primarily contains water-soluble compounds like fulvic and ulmic acids. It is important to note that the drying process of peat can negatively impact the water solubility of its active components.
Safety
Safety Profile
Peat Moss Extract has not undergone specific safety assessments by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS), and no maximum concentration guidelines are established by these bodies. The FDA regulates cosmetics differently from drugs, without pre-market approval for cosmetic ingredients. However, the ingredient is reported as 'Irritant Free' by SkinSAFE and is well-tolerated, even by sensitive skin, with no measurable side-effects observed in skincare applications.
