CITRUS TANGERINA FRUIT.

Valuable CAS 223748-44-5 / SKIN CONDITIONING

A multifunctional botanical extract concentrated in Vitamin C and flavonoids, designed to bridge the gap between skin brightening and neuro-sensory soothing. It provides a precision approach to environmental defense by neutralizing free radicals while modulating the skin's biological response to irritation.

Summary

Antioxidant TRPV1 Modulator Skin Brightening Antibacterial Collagen Booster

Science

Mechanism of Action

This extract functions through a multi-pathway approach: it inhibits melanin generation and promotes collagen synthesis via high ascorbic acid content, while simultaneously acting as a TRPV1 antagonist. By modulating the activation and protein expression of these heat-sensing receptors, it effectively raises the skin's tolerance threshold against chemical and environmental triggers.

Key findings

  1. 01 In vitro studies demonstrate that concentrations of 1%-4% significantly inhibit TRPV1 activation induced by common irritants like phenoxyethanol and nicotinamide.
  2. 02 A concentration of 0.25% was shown to suppress TRPV1 protein expression in HaCaT cells, reducing cellular sensitivity.
  3. 03 In vivo testing confirmed that topical application provides instant relief from lactic acid-induced discomfort in under 5 minutes, with cumulative benefits after 7 days of use.

Stability

Highly dependent on the removal of phototoxic furocoumarins; should be stored in opaque packaging to prevent oxidation of its ascorbic acid content.

Synergies

  • L-Ascorbic Acid
  • Niacinamide
  • Tocopherol
  • Hyaluronic Acid

Conflicts

  • High concentrations of 5-methoxypsoralen (5-MOP)
  • Unbuffered high-acid formulas that may exacerbate citrus-derived sensitization
