Map – Magnesium Ascorbyl Phosphate (Cosmetic Grade)  

Magnesium Ascorbyl Phosphate (MAP) is a stable, water-soluble derivative of Vitamin C used in cosmetic formulations. Unlike pure Vitamin C (ascorbic acid), which oxidizes quickly, MAP is much more gentle, long-lasting, and suitable for sensitive skin, while still providing skin-brightening and anti-aging benefits.

What is MAP

• A Vitamin C derivative: ascorbic acid (Vitamin C) bound with magnesium and phosphate.
• Cosmetic grade → purified and safe for skincare applications.
• Known as one of the most stable forms of Vitamin C in water-based products.

Properties

• Appearance: White to off-white crystalline powder.
• Solubility: Water-soluble (pH range 6–7 is ideal).
• Stability: Much more stable than L-ascorbic acid → doesn’t oxidize as fast.
• Skin Feel: Non-irritating, even for sensitive skin.

Benefits of Skincare

Skin Brightening

• Inhibits tyrosinase enzyme → reduces melanin production → lightens hyperpigmentation, dark spots, and melasma.

Anti-Aging

• Stimulates collagen synthesis, improving skin firmness and reducing wrinkles.
• Protects against photoaging from UV damage.

Antioxidant Protection

• Neutralizes free radicals → slows down skin aging.

Gentle on Skin

• Much less irritating than pure Vitamin C → suitable for sensitive and acne-prone skin.

Common Cosmetic Applications

• Brightening serums
• Anti-aging creams
• Sunscreens (as an antioxidant booster)
• Spot treatments for pigmentation
• Hydrating lotions (paired with hyaluronic acid or niacinamide)

Recommended Usage Levels

• 1–10% in formulations (3–5% most common in serums/creams).
• Works best in water-based formulations at a pH around 6–7.

Safety & Precautions

• Very safe and well tolerated (less irritation than ascorbic acid).
• May lose potency if stored in hot, humid conditions → store in airtight, cool, dry container.
• For external use only (not edible).
