Science
Mechanism of Action
Thujic acid functions by gently exfoliating the skin, likely through a mechanism similar to alpha hydroxy acids (AHAs) where it helps break down intercellular bonds. This action promotes a smoother, more radiant skin surface and contributes to the reduction of hyperpigmentation.

Formulation
Stability
Thujic acid exhibits water solubility, estimated at 298.8 mg/L at 25 °C. While no specific optimal pH range for its stability in formulations was identified, topical products generally perform best and maintain skin health within a pH range of 4 to 6.
Conflicts
- Potential pH incompatibilities with other ingredients that could compromise effectiveness or disrupt the skin barrier.
- Increased irritation when combining with multiple other strong active ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not conducted a specific safety assessment for Thujic acid, and no maximum concentration recommendations from CIR or the Scientific Committee on Consumer Safety (SCCS) are available. In the U.S., cosmetic ingredients generally do not require FDA approval prior to market entry, and Thujic acid is not listed as a prohibited or restricted substance within the provided context.

Verdict
Thujic acid demonstrates promising exfoliating and skin-enhancing properties akin to AHAs, but a lack of specific clinical efficacy, safety concentrations, and comprehensive irritancy/comedogenicity data necessitates further investigation for precise formulation and application.
