Science
Mechanism of Action
Peat extract, abundant in humic and fulvic acids, supports skin health through multiple pathways. It promotes a balanced and diverse skin microbiome, strengthening the skin barrier and facilitating wound healing. Its potent anti-inflammatory properties reduce irritation, while its antioxidant capabilities combat oxidative stress by reducing reactive oxygen species (ROS), thereby helping to prevent signs of aging. Peat also exhibits antimicrobial activity against pathogens like *Staphylococcus aureus*, offers mild astringent and some UVB-protective effects, and contributes to improved hydration via its water-retention capacity. Additionally, it aids in gentle exfoliation, supports skin metabolism and blood circulation, and provides a clarifying effect by helping to clear clogged pores.

Key findings
- 01 Daily topical application of peat significantly benefited patients with chronic hand dermatitis and psoriasis palmaris, resulting in faster itch relief, reduced inflammation, and earlier cessation of pustule formation.
- 02 Demonstrated antimicrobial activity against skin pathogens (e.g., inhibiting *Staphylococcus aureus* while promoting *Staphylococcus epidermidis*), maintaining skin microbiome vitality and diversity. Showed anti-ageing effects, including modulating cellular senescence, promoting wound healing, modulating keratinocyte differentiation markers (K10, K16), increasing E-cadherins (B1, B2), and inhibiting sphingomyelinase activity. Provided antioxidant protection by reducing reactive oxygen species and 8-isoprostane levels.
- 03 Increased the proliferative response of phytohemagglutinin-stimulated human lymphocytes. Inhibited HIV-1 infection of MT-2 cells.

Dusting Analysis
Peat presents a wide array of documented benefits, including anti-inflammatory, antimicrobial, antioxidant, and barrier-supporting properties, indicating its genuine activity rather than being a 'dusting' ingredient.
The Formula
Formulation
Stability
Formulations containing sapropel extract (a peat type) exhibit good stability and spreadability within a pH range of 4.7 to 7.4 over a two-year period. However, the drying process can negatively impact peat's water solubility.
Conflicts
- No specific chemical incompatibilities are widely documented, though diligent excipient compatibility assessment is prudent for complex herbal extracts.
- When utilized in mask formulations for its impurity-absorbing properties, combining peat with certain other ingredients might 'disturb its process'.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) primarily evaluates individual chemical compounds and has not specifically reviewed peat or peat extract. Similarly, no specific safety opinions from the FDA or SCCS were identified; peat is not listed as a prohibited or restricted ingredient by the FDA.
