Science
Mechanism of Action
The synergy between *Sparassis crispa* and *Lactobacillus* fermentation creates a multifaceted ingredient for comprehensive skin health. *Sparassis crispa* extract, abundant in β-glucans and antioxidants, delivers profound hydration, alleviates inflammation, supports restorative processes, and strengthens the skin's natural barrier. It has been observed to improve stratum corneum turnover, increase dermal soluble collagen content, and effectively reduce transepidermal water loss (TEWL). The *Lactobacillus* fermentation process significantly amplifies the antioxidant capacity and overall bioactivity of the mushroom extract. Furthermore, the *Lactobacillus* ferment component is reported to act as a DNA repair enzyme, offer protection against environmental aggressors, and possess antimicrobial and anti-inflammatory properties, which can aid in managing concerns like acne and rosacea by fostering a healthy skin microbiome.

Stability
Optimal pH for the mycelial growth of *Sparassis crispa* has been noted between 5-7, with highest growth at pH 6. Another study indicated optimal mycelial growth at pH 4.0-5.0. However, specific optimal pH for the stability of the final ferment extract within a cosmetic formulation is not explicitly detailed in the provided data.
Safety
Safety Profile
The CIR Expert Panel concluded that 'Lactobacillus Ferment' (a component of this ingredient) is safe for cosmetic use, with a maximum reported concentration of 5.6% in face and neck products. While *Sparassis crispa* extract is generally recognized as safe, some individuals might experience mild skin irritation or allergic reactions; a patch test is recommended. Regulatory authorities widely accept this ingredient for cosmetic applications. It is important to note that Lactobacillus Ferment may exhibit a skin lightening effect by inhibiting tyrosinase, and formulators should ensure product development avoids unintended skin depigmentation.
