CITROFORTUNELLA MICROCARPA FRUIT EXTRACT.

Valuable / ANTIOXIDANT, SKIN CONDITIONING

Derived from the calamansi fruit, Citrofortunella Microcarpa Fruit Extract is a multifaceted botanical active. It delivers significant antioxidant protection against environmental stressors while actively stimulating collagen production. This extract also contributes to skin conditioning, promoting a smoother texture and aiding in melanin reduction for a brighter, more even complexion.

Antioxidant Skin Conditioning Collagen Stimulator Skin Brightening Melanin Inhibitor Photoprotective

Science

Mechanism of Action

This extract operates as a potent antioxidant by effectively neutralizing free radicals, thereby mitigating oxidative stress and premature cellular aging. It enhances skin barrier integrity through its conditioning properties, fostering hydration and a refined texture. Furthermore, it demonstrates collagen-stimulating capabilities, likely due to its robust antioxidant profile, and exhibits notable tyrosinase inhibitory activity, which reduces melanin synthesis for a visibly brighter skin tone. Its rich composition includes Vitamin C, D-Limonene, flavonoids, and essential oils, contributing to its diverse beneficial actions.

Key findings

  1. 01 At a 0.2% concentration, the extract exhibited significant collagen-stimulating effects in zebrafish models and comparable photoprotective potential to commercial sunscreens across specific UV wavelengths. No toxicity was observed at this concentration.
  2. 02 Demonstrated substantial skin whitening effects by inhibiting tyrosinase activity by up to 69.28% and reducing melanin production by up to 78.9% relative to control in Clone M-3 cells. Extraction yields for active compounds were noted at 21.55% and 13.27% (w/w).

Dusting Analysis

Not commonly dusted

Clinical research supports efficacy at a 0.2% concentration for specific benefits like collagen stimulation and photoprotection, indicating its inclusion is for functional benefits rather than merely label claims. Data on skin whitening efficacy did not specify a final product concentration, but its significant biological activity suggests it is not typically 'dusted'.

Stability

Formulations incorporating calamansi rind extract maintain stable appearance and quality over at least a three-week period at both room temperature and temperatures exceeding 40°C, with minimal pH alterations observed. Such formulations are typically acidic.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

Generally recognized as safe for topical cosmetic use, including both rinse-off and leave-on products, provided formulations are non-sensitizing and non-irritating. For leave-on products, it must contain no more than 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP). The FDA also recognizes citrus fruits as Generally Recognized As Safe (GRAS) for food use. While rare, potential side effects such as skin irritation, allergic reactions, or photosensitivity are possible; therefore, patch testing is advised.
