Skin-brightening Antioxidant Humectant Anti-inflammatory Skin-conditioning Perfuming

Science

Mechanism of Action

Citrus Depressa Peel Extract exerts its effects primarily through its high concentration of polyphenols, including specific flavonoids like hesperidin, nobiletin, tangeretin, and sinensetin. These active compounds are recognized for their potent antioxidant activity, neutralizing free radicals and mitigating oxidative stress. They also demonstrate anti-inflammatory properties, which can help soothe irritated skin. As a skin-conditioning agent, it aids in maintaining the skin's moisture barrier by acting as a humectant, drawing and retaining water in the stratum corneum. Furthermore, similar citrus extracts suggest a potential to brighten skin complexion by inhibiting tyrosinase, the enzyme crucial for melanin synthesis, and providing protection against UV-induced damage.

Conflicts

  • High concentrations of photosensitizing furocoumarins, such as 5-methoxypsoralen (5-MOP), can lead to phototoxicity in leave-on formulations.
  • Potential for irritation or allergic reactions in individuals with sensitive skin, especially if the extract is not properly processed or contains higher levels of essential oil components.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deems citrus peel extracts, including Citrus Depressa Peel Extract, safe for cosmetic use (both rinse-off and leave-on) provided they are formulated to be non-sensitizing and non-irritating. A critical safety restriction for leave-on products is that the finished formulation must contain no more than 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP) to prevent photosensitivity reactions. The FDA recognizes certain citrus peels and extracts as generally safe (GRAS) for food applications.
