Science
Mechanism of Action
The ingredient functions through a dual mechanism. Hypericum Perforatum contributes active compounds like hyperforin and hypericin; hyperforin acts as an antioxidant, anti-inflammatory, and antimicrobial agent, protecting skin from free radical damage, soothing irritation, and supporting skin cell regeneration. Concurrently, the Lactobacillus ferment filtrate delivers beneficial byproducts such as enzymes, peptides, and organic acids, which help to maintain a healthy skin microbiome, strengthen the skin's natural barrier, and improve overall skin appearance through enhanced hydration and clarity. Together, these components provide comprehensive soothing, antioxidant, and barrier-supportive actions.

Key findings
- 01 While specific clinical studies on the combined LACTOBACILLUS/HYPERICUM PERFORATUM FLOWER/LEAF/STEM EXTRACT FERMENT FILTRATE with defined effective concentrations are not widely published, research on its individual components offers significant insights.
- 02 Studies on Hypericum Perforatum extract (St. John's Wort) demonstrate efficacy in reducing flaking and restoring suppleness in dry or damaged skin. It also provides calming sensations, soothes irritated and reddened skin, and exhibits antimicrobial properties beneficial for acne-prone skin.
- 03 General ferment filtrates have been shown to reduce hyperpigmentation by decreasing melanin synthesis, reinforce the skin barrier, mitigate acne, and help regulate sebum production.

The Formula
Formulation
Stability
The stability of Hypericum Perforatum extracts, specifically hypericin levels, can be influenced by the plant's origin, extraction methods, solvent lipophilicity, and storage conditions. Formulators should consider these factors to maintain ingredient integrity and efficacy.
Synergies
- The combination of Hypericum Perforatum and Lactobacillus ferment filtrate offers enhanced soothing, antimicrobial, antioxidant, and skin barrier support through their complementary mechanisms of action.
Conflicts
- Sunlight exposure (due to the photosensitizing compound hypericin found in Hypericum Perforatum extract). Products containing this ingredient should be designed for nighttime use or paired with robust daily SPF protection.
Safety
Safety Profile
The CIR Expert Panel deems Hypericum Perforatum Flower/Leaf/Stem Extract safe up to 0.07%. However, it carries a significant photosensitivity risk due to hypericin, which increases skin sensitivity to UV radiation. Lactobacillus Ferment ingredients are generally considered safe for cosmetic use up to 5.6%. When formulating with this combined ingredient, the 0.07% concentration limit for the Hypericum component must be observed, and care must be taken to avoid skin depigmentation, which is classified as a drug effect. Users should be advised of the photosensitivity risk and consider product usage, especially in daylight.

Verdict
This ingredient offers valuable benefits for soothing, barrier strengthening, and antimicrobial action across all skin types, but its formulation requires careful consideration of photosensitivity due to Hypericum Perforatum, especially at its maximum safe concentration of 0.07%.
