Science
Mechanism of Action
As an enzyme, Soybean Peroxidase efficiently counteracts free radicals, mitigating oxidative stress that contributes to premature skin aging. It actively conditions the skin, promoting improved texture, hydration, and softness. SBP also catalyzes the oxidation of various organic compounds using hydrogen peroxide, generating hypohalous acid, which provides antimicrobial benefits. Furthermore, in vitro studies indicate its potential to stimulate collagen I biosynthesis and matrix mineralization in human osteoblasts.

Key findings
- 01 In vitro studies on human osteoblasts demonstrated that increasing concentrations of Soybean Peroxidase significantly promoted collagen I biosynthesis and enhanced matrix mineralization. While these findings suggest a pro-osteogenic ability and potential for collagen stimulation, they are primarily related to bone regeneration and require further investigation for direct application to skin efficacy.

The Formula
Formulation
Stability
Soybean Peroxidase (SBP) exhibits high catalytic activity and thermostability, particularly optimal at pH 5.5, with enzyme activity peaking at pH 4.5. It retains activity across a broad pH range of 3.0 to 13.0, with oxidative reactions typically performed between pH 3.0 and 10.0, especially 4.0-9.0. Activity can be compromised below pH 5.5 and is completely abolished at very low pH (2.5-5.0 within 24 hours). SBP also demonstrates activity in various organic solvents including acetone, acetonitrile, methanol, and ethanol.
Safety
Safety Profile
Soybean Peroxidase is generally considered safe for topical cosmetic application, with infrequent reports of adverse reactions such as skin irritation or allergic responses. A patch test is recommended prior to widespread use. Data regarding topical usage during pregnancy and breastfeeding are currently insufficient, advising consultation with a healthcare professional for these individuals. The EWG indicates that products cannot be EWG VERIFIED if they contain this ingredient without adequate substantiation, and while soybeans are GRAS as food, this status does not specifically apply to SBP as a cosmetic ingredient.
