The Ordinary Magnesium Ascorbyl Phosphate 10%
The Ordinary Magnesium Ascorbyl Phosphate 10% is a skin-brightening cream formulated with a stable Vitamin C derivative. Unlike pure L-Ascorbic Acid, Magnesium Ascorbyl Phosphate (MAP) is water-soluble, making it less irritating and more suitable for those with sensitive skin types who find traditional Vitamin C serums too harsh. This product aims to even out skin tone, boost radiance, and provide essential antioxidant protection against environmental stressors. The texture is a lightweight, non-greasy cream that provides a hydrating feel, largely due to its emollient-rich base featuring Coco-Caprylate/Caprate and Isodecyl Neopentanoate. It also incorporates Plukenetia Volubilis Seed Oil, which is rich in fatty acids to help support the skin's natural moisture barrier. While it offers the potent brightening benefits of Vitamin C in a stable, easy-to-use format, its specific blend of emollients and thickeners carries significant implications for those with congestion-prone skin. It is a moisturizing alternative to high-strength acids, providing a more comfortable application experience for those prioritizing skin tone uniformity and hydration.
Our Analysis
Our ingredient analysis for The Ordinary Magnesium Ascorbyl Phosphate 10% indicates a High comedogenic risk. The formula contains two high-risk ingredients: Coconut Alkanes (rated 4/5) and Polyglyceryl-3 Diisostearate (rated 4/5). Coconut alkanes, while providing a smooth glide, can be occlusive and trap sebum or bacteria in the pores. Polyglyceryl-3 Diisostearate is a heavy emollient that may form a film on the skin, potentially leading to breakouts in acne-prone individuals. Additionally, the inclusion of Tocopherol (Vitamin E) adds a minor risk (2/5) for those highly sensitive to heavy oils. This product is best used by those without acne concerns.
Skin Type Recommendations
This product is best suited for dry, mature, or normal skin types that require hydration and brightening without the risk of acne. It is not recommended for oily, combination, or acne-prone skin, as the high concentration of comedogenic ingredients like coconut alkanes may lead to increased congestion and breakouts.
Flagged Ingredients
Derived from coconut fatty acids. While lighter than pure oil, it retains occlusive properties that can trap bacteria.
Heavy emollient that can form a suffocating film on the skin.
Pure Vitamin E is thick and sticky; safe in small amounts as an antioxidant, but potentially clogging in pure oil form.
