Ever wondered what makes your favorite skincare products so effective? Dive into our comprehensive guide on Magnesium Ascorbate and discover its transformative benefits, how it's made, and what to watch out for in your beauty routine.

What Is Magnesium Ascorbate?

Magnesium Ascorbate, also known as Magnesium di-L-ascorbate, is a derivative of Vitamin C (ascorbic acid) combined with magnesium. This ingredient is primarily sourced from the combination of ascorbic acid and magnesium salts. In the world of cosmetics, it is celebrated for its dual role as an antioxidant and a skin conditioning agent.

The history of Magnesium Ascorbate in cosmetics is relatively recent compared to other ingredients. Initially, Vitamin C was used in its pure form, but it was found to be unstable and prone to oxidation, which reduced its effectiveness. To combat this, scientists developed more stable derivatives, including Magnesium Ascorbate. This innovation allowed for the benefits of Vitamin C to be harnessed more effectively in skincare formulations.

Magnesium Ascorbate is synthesized through a chemical reaction that combines ascorbic acid with magnesium oxide or magnesium carbonate. This process results in a compound that retains the beneficial properties of Vitamin C while being more stable and less irritating to the skin. This makes it a popular choice for a variety of skincare products, including serums, creams, and lotions.

The Benefits/Uses of Magnesium Ascorbate

In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Ascorbate:


Magnesium Ascorbate acts as a powerful antioxidant. In simpler terms, this means it helps to protect your skin from damage caused by free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging and other skin issues. By neutralizing these harmful molecules, Magnesium Ascorbate helps to maintain the skin’s youthful appearance and overall health.

Skin Conditioning

Another significant benefit of Magnesium Ascorbate is its skin conditioning properties. This means it helps to improve the appearance and feel of your skin. It can make your skin softer, smoother, and more hydrated. Essentially, it enhances the overall texture and suppleness of your skin, making it look and feel better.

Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Magnesium Ascorbate is generally considered safe for topical use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind:

  • Skin irritation
  • Redness
  • Itching
  • Allergic reactions

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Ascorbate during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Magnesium Ascorbate are relatively uncommon, but they can occur. To minimize the risk of irritation or allergic reaction, it is recommended to perform a patch test before widespread usage.

Magnesium Ascorbate has a comedogenic rating of 1, meaning it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
