Science
Mechanism of Action
R-Perillic Acid acts as a robust cosmetic preservative by demonstrating broad-spectrum antimicrobial and antifungal efficacy against Gram-positive and Gram-negative bacteria, yeasts, and molds/mycobacteria. This capability protects cosmetic products from microbial spoilage, oxidative processes, and chemical degradation. Furthermore, *in vitro* studies indicate its capacity to inhibit the growth of skin cancer cells via blocking α1 subunit activity, subsequently reducing growth factor-β1 and c-jun phosphorylation. It also induces cancer cell apoptosis by disrupting DNA synthesis and interfering with the prenylation of oncogenic proteins.

Verdict
Perillic Acid serves as an effective broad-spectrum preservative with intriguing *in vitro* cytotoxic properties, yet comprehensive clinical efficacy and topical safety data specific to healthy skin applications remain insufficient for a definitive verdict on its broader skincare utility.
