THE STORY OF MAGNESIUM ASCORBYL PHOSPHATE
MAP: The Stable, Gentle Vitamin C for Bright, Hydrated & Even-Toned Skin
Magnesium Ascorbyl Phosphate (MAP) is a highly stable, water-soluble derivative of Vitamin C.
It offers powerful brightening, antioxidant, and collagen-supporting benefits without the irritation associated with pure ascorbic acid.
Perfect for sensitive, dry, and mature skin, MAP is widely used in brightening serums, anti-aging creams, sunscreens, and moisturizers.
Stabilized Vitamin C Phosphate Ester Bonded with Magnesium for Maximum Skin Compatibility
MAP is created by phosphorylating Ascorbic Acid and bonding it with magnesium salts, forming a stable Vitamin C derivative that:
• Resists oxidation
• Is gentle on sensitive skin
• Works in a broader pH range (pH 6–7)
• Converts into active Vitamin C (ascorbic acid) once absorbed
TRCkem supplies high-purity MAP suitable for premium brightening and anti-aging skincare.
