Science
Mechanism of Action
This essential oil acts through the synergistic effects of its key constituents. Limonene provides antibacterial and anti-inflammatory properties, assisting in the reduction and prevention of breakouts, while myrcene and nerol contribute to calming irritation and diminishing redness. Its robust antioxidant profile, including vitamin C and alpha-pinene, actively combats free radicals and environmental stressors, thereby mitigating premature signs of aging. Furthermore, vitamin C supports collagen synthesis and accelerates cellular turnover, enhancing skin radiance and addressing concerns of dullness and hyperpigmentation.

Safety
Safety Profile
The CIR Expert Panel concluded that citrus-derived peel oils are safe for use in cosmetic products, excluding rinse-off formulations, provided they contain no more than 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP) and are formulated to be non-sensitizing and non-irritating. Cold-pressed tangerine oil typically contains 50 ppm of 5-MOP, requiring careful processing or dilution to meet this restriction. Due to potential phototoxicity, it is strongly advised to avoid direct sunlight exposure after application, or to restrict use to evening routines. The FDA lists essential oils and extracts from tangerine peel as Generally Recognized As Safe (GRAS) for food use.
