What is Calcium Ascorbate?

Calcium ascorbate, often referred to as Ester-C, is a stable, non-acidic form of vitamin C (ascorbic acid) bound to calcium. It serves as a powerful antioxidant in skincare and helps neutralize free radicals, protecting the skin from oxidative stress caused by UV radiation, pollution, and other environmental aggressors. This protection is essential for anti-aging, as it minimizes damage that can lead to fine lines, wrinkles, and loss of elasticity.

 

 

Chemical Composition and Stability

The chemical structure of calcium ascorbate, C₁₂H₁₄CaO₁₂, combines calcium with ascorbic acid, enhancing its stability compared to pure ascorbic acid (L-ascorbic acid), which is prone to degradation when exposed to air and light. This stability is particularly beneficial in skincare formulations, as calcium ascorbate retains its antioxidant potency longer, ensuring more consistent results.

Additionally, calcium ascorbate's non-acidic nature makes it gentler on the skin, reducing the risk of irritation that can sometimes occur with other forms of vitamin C, such as ascorbic acid. This makes it a suitable option for individuals with sensitive skin or those who experience discomfort when using more acidic vitamin C products.

 

 

Applications in Skincare and Cosmetics

Calcium ascorbate can be found in a variety of skincare and cosmetic products due to its versatility and effectiveness. Key applications include:

Anti-Aging Serums: It promotes collagen synthesis, which helps maintain skin firmness and elasticity while reducing the appearance of wrinkles.

Brightening Treatments: Calcium ascorbate helps even out skin tone by reducing hyperpigmentation and dark spots, making the skin appear brighter and more radiant.

Moisturizers: Its antioxidant properties make it an excellent addition to hydrating creams, helping to protect the skin barrier and reduce the visible signs of aging.

 

 

Source and Origins

Calcium ascorbate is synthesized for use in cosmetic and dietary products. It is commonly found in supplements and topical formulations due to its enhanced bioavailability and stability.

FDA and Safety Information

Calcium ascorbate is considered safe for use in skincare and cosmetic formulations. It is recognized by the FDA as a GRAS (Generally Recognized As Safe) substance for dietary supplements and food additives, and its topical use in skincare is similarly regarded as non-toxic and safe. The typical concentration of calcium ascorbate in skincare products ranges from 0.2% to 2%, with higher percentages used for more targeted treatments, such as brightening serums or anti-aging creams.

 

 

Usage Levels in Formulations

In cosmetics, calcium ascorbate is commonly used at concentrations ranging from 0.2% to 2%. It is frequently combined with other antioxidants like vitamin E and ferulic acid to enhance its stability and efficacy. In formulations aimed at addressing visible signs of aging, concentrations can vary depending on the product's intended results and skin compatibility.

 

 

Why Choose Calcium Ascorbate?

Calcium ascorbate offers the same potent antioxidant benefits as other forms of vitamin C but with improved stability and a reduced risk of irritation. Its ability to stimulate collagen production makes it a key player in anti-aging skincare. When combined with other skincare actives, it works synergistically to enhance the skin's defense against external stressors while promoting a youthful, radiant appearance.

Its non-acidic nature and stability make calcium ascorbate an appealing choice for those looking to incorporate vitamin C into their routine without experiencing the irritation that can sometimes accompany other forms of this powerful antioxidant.
