Science
Mechanism of Action
This extract enhances skin cell vitality by activating fundamental metabolic pathways. It notably increases ATP synthesis and stimulates cytochrome C oxidase activity, both critical for cellular energy production. The extract also induces ribose 5-phosphate synthesis, thereby regulating the skin's overall metabolic and energy processes. Beyond energizing, it provides antioxidant protection against environmental factors, improves complexion radiance, enhances moisture retention, and stimulates collagen synthesis for improved firmness and elasticity. Furthermore, it exhibits skin-brightening properties by inhibiting melanin formation and reducing the visibility of hyperpigmentation. Anti-inflammatory effects are observed through decreased pro-inflammatory cytokines (TNF-α) and increased anti-inflammatory cytokines (IL-10). It also possesses antimicrobial properties, beneficial for skin and scalp health, and may contribute to inhibiting unwanted hair growth by suppressing hair follicle cell proliferation.

Key findings
- 01 Diluted Gymnema sylvestre extract at 0.25% in culture medium for human keratinocytes demonstrated a significant effect on regulating metabolic and energetic processes, including enhanced ATP synthesis and stimulated cytochrome C oxidase activity.
- 02 At concentrations of 0.125% and 0.25%, the extract applied to fibroblasts in culture showed positive effects on their metabolic and energetic processes.
- 03 Gymnema sylvestre extract displayed antimicrobial action against specific bacteria in biofilms at concentrations from 22.12 mg/mL to 88.5 mg/mL. At these concentrations, human keratinocyte (HaCaT) viability remained robustly above 80%. Additionally, the extract exhibited antioxidant activity with an EC50 of 353.43 µg/mL.

Dusting Analysis
No data suggests that Gymnema Sylvestre Cell Culture Extract is commonly associated with dusting or has specific dusting thresholds.
The Formula
Formulation
Stability
While a specific optimal pH range for cosmetic formulations was not identified, the pH of a 1% solution of Gymnema sylvestre powder was 6.93, and a dried ethanolic extract measured 6.8. Gymnemic acids, key active components, have demonstrated stability under WHO-recommended accelerated and long-term storage conditions. For cell culture production, an initial medium pH of 5.8 to 6.0 favored biomass and gymnemic acid yield.
Safety
Safety Profile
No specific safety assessments from CIR, SCCS, or FDA were found for 'GYMNEMA SYLVESTRE CELL CULTURE EXTRACT'. However, in vitro studies on human keratinocytes (HaCaT) indicated low cytotoxicity, with cell viability consistently above 80% at tested concentrations. General Gymnema sylvestre extract (not cell culture) has shown a high acute oral LD50 greater than 5 kg/BW in rats, classifying it as non-toxic for internal consumption, with limited human and in vivo toxicological studies suggesting a lack of relevant adverse effects at typical doses. However, very high internal doses (300 and 600 mg/kg BW) in rats were noted to affect liver and kidney function, while 100 mg/kg BW did not cause significant alterations. These internal toxicity data are not directly applicable to topical cosmetic use but inform a broader safety profile.
