Ascorbyl Tetraisopalmitate

1. Ascorbyl Tetraisopalmitate Feature

As a lipid-soluble derivative of vitamin C, Ascorbyl Tetraisopalmitate (VC-IP) delivers a dual-action antioxidant mechanism:

Direct Radical Scavenging: Neutralizes reactive oxygen species (ROS) caused by UV rays, pollution, and environmental stress, reducing lipid peroxidation and DNA damage.

Endogenous Defense Boost: Enhances the activity of superoxide dismutase (SOD) and other antioxidant enzymes to strengthen the skin's self-protective barrier.
Research Insight: VC-IP demonstrates 16.5x higher transdermal absorption than water-soluble vitamin C, enabling long-lasting antioxidant effects in the dermis.

2. Ascorbyl Tetraisopalmitate for Skin

Ascorbyl Tetraisopalmitate stands out from traditional vitamin C with its low irritation and high stability:

pH-Neutral Design: Activates without an acidic environment, minimizing redness and sensitivity risks.

Thermal Stability: Maintains efficacy above 40°C, suitable for diverse formulations (e.g., sunscreens, facial oils).
Regulatory Approval: Approved by Japan's Ministry of Health as a quasi-drug active ingredient (3% concentration) and registered in South Korea for brightening effects (2% concentration).
