Science
Mechanism of Action
Functioning as a cytolytic detergent, deoxycholic acid physically disrupts the phospholipid bilayer of adipocytes (fat cells). This process, known as adipocyte lysis, triggers a localized inflammatory response that clears cellular debris, resulting in a visible reduction of the fat pocket and subsequent tissue tightening.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 FDA approval trials for Kybella (10 mg/mL) demonstrating significant submental fat reduction.
- 02 Phase 3 clinical trials evaluating dosage densities of 1 mg/cm² versus 2 mg/cm² for efficacy.
- 03 Case series data exploring diluted concentrations (2.5 mg/mL and 5 mg/mL) for upper arm fat contouring.
Transparency
Dusting Analysis
While highly effective as an injectable at 1% concentrations, topical applications often lack the necessary depth of penetration or concentration to induce true adipocyte lysis, leading to decorative 'slimming' claims without biological efficacy.
The Formula
Formulation
Stability
Aqueous stability is highly pH-dependent; solutions must be maintained above pH 8.0 to prevent precipitation. The sodium salt form is water-soluble, whereas the acid requires organic solvents like ethanol or DMSO.
Synergies
- Organic solvents (DMSO, Ethanol)
- Anionic surfactants
Conflicts
- Cationic surfactants (e.g., Cetrimonium Bromide)
- Acidic environments (pH < 7.0)
Safety
Safety Profile
Primarily approved for submental use. Potential side effects include localized edema, bruising, and transient numbness. Deep injection is required to avoid skin necrosis or ulceration.
