Performance & Formulation Insights for AccessWHITE MAP
How Magnesium Ascorbyl Phosphate Works
AccessWHITE MAP leverages Magnesium Ascorbyl Phosphate (MAP), a stable, water-soluble Vitamin C derivative recognized for brightening and antioxidant performance. Once applied, MAP can convert to ascorbic acid within the skin, where it helps modulate melanogenesis by interfering with the tyrosinase pathway. By limiting the oxidation steps involved in melanin synthesis and helping to reduce reactive quinones back to less pigmented forms, MAP diminishes the appearance of dark spots and uneven tone. In parallel, its antioxidant activity helps neutralize free radicals generated by UV exposure and pollution, and it supports collagen synthesis for improved firmness and overall skin resilience.
Formulation Guidelines
AccessWHITE MAP is a white to off-white powder that dissolves in water. For best results, add it to the water phase; gentle heating to about 40 °C (104 °F) can help achieve full dissolution. To preserve color and activity, maintain a final formulation pH between 6.0 and 7.5. MAP is less pH-sensitive than L-Ascorbic Acid yet performs optimally in this near-neutral range. Typical usage is 0.2–3% for daily antioxidant and brightening benefits, with up to 10% for intensive dark spot correction. Avoid pairing with actives that require very low pH to ensure stability and compatibility.
