Application
As an efficient and gentle whitening and anti-aging core ingredient, VC-IP is the preferred choice for high-end efficacy skincare. Suitable for all skin types, including sensitive skin and niacinamide-intolerant skin, its transdermal absorption rate is 16.5 times that of water-soluble vitamin C. It rapidly penetrates the stratum corneum and is hydrolyzed into active vitamin C by skin enzymes for continuous performance. Its excellent formula compatibility makes it a key ingredient in modern "oil-nourishing skin" formulations.
  • ✨
    1. Whitening and Spot Lightening
    Accurately inhibits tyrosinase activity to block melanin generation at the source. Effectively improves dullness, prevents tanning after sun exposure, and reduces post-inflammatory acne marks and spots. Long-term use promotes an even, radiant complexion. Recognized as an official whitening active ingredient in multiple regions.
  • 🛡️
    2. Antioxidant and Anti-Aging
    Efficiently scavenges free radicals, prevents skin lipid peroxidation, reduces UV-induced cellular DNA damage, and provides reliable photoprotection. Simultaneously promotes dermal collagen synthesis, inhibits matrix metalloproteinase activity, reduces fine lines, and enhances elasticity.
  • 🌿
    3. Gentle Barrier Repair
    Features extremely low irritation with a risk factor of only 1, eliminating the need to build tolerance. Soothes skin while maintaining barrier integrity, making it ideal for daily sensitive skin care and enhancing the overall tactile feel of skincare formulations.
🧴 Common Application Products
High-end whitening essence oils, anti-aging serums, face creams, lotions, sunscreens, post-sun repair products, and facial masks — especially suited for "oil skincare" dosage forms. Works synergistically with niacinamide, vitamin E derivatives, peptides, and other active ingredients to maximize overall product efficacy.
⚗️ Recommended Dosage
0.1%–2.0% is recommended for leave-on products (creams, serums). Formulations with concentrations up to 4% are recognized as safe by US CIR assessments. For rinse-off products (cleansers, shampoos), adding up to 0.05% is advised. Stability can be further optimized by combining 0.1–0.3% tocopherol and disodium EDTA.

Storage & Handling
🌡️

Frequently Asked Questions
Q
What is VC-IP and how does it differ from regular Vitamin C?
VC-IP (Ascorbyl Tetraisopalmitate) is an oil-soluble, highly stable derivative of Vitamin C. Unlike standard water-soluble L-Ascorbic Acid, VC-IP resists oxidation, causes negligible irritation, and achieves a transdermal absorption rate 16.5 times higher for deeper skin enzyme conversion.
Q
Is VC-IP safe and effective for sensitive skin?
Yes. VC-IP carries an exceptionally low irritation rating (risk factor 1). It requires no skin tolerance build-up period and is perfectly suitable for sensitive or niacinamide-intolerant skin.
Q
What is the recommended usage concentration in formulations?
For leave-on skincare products like facial creams and serums, a concentration of 0.1%–2.0% is recommended (safe up to 4% per US CIR guidelines). For rinse-off applications such as cleansers, a maximum concentration of 0.05% is suggested.
Q
Can VC-IP be combined with other active cosmetic ingredients?
Yes. VC-IP exhibits outstanding compatibility with ingredients like niacinamide, vitamin E derivatives, peptides, tocopherol, and disodium EDTA. Adding 0.1–0.3% tocopherol can further enhance stability in oil phase systems.
Q
What are the ideal storage conditions for VC-IP?
VC-IP should be kept in a sealed container in a cool, dry, dark, and well-ventilated space. Keep away from strong acids, bases, oxidizers, and volatile odorous substances while elevating off floor surfaces to avoid moisture.
Q
In which regions is VC-IP officially approved as a whitening agent?
VC-IP is recognized as a quasi-drug / legal active whitening ingredient in key cosmetic markets including Japan, South Korea, and Taiwan, confirming its proven regulatory standing and clinical performance.
