Ordinary Vitamin-C Doesn't Last

By now everyone's heard that cosmetics containing vitamin C reduce sun damage and erase wrinkles. But what most people don't know is that ordinary vitamin C disappears upon contact with air, water, heat and light. Since cosmetics inevitably encounter all of these elements, any vitamin C that was initially present probably vanished before the jar was even opened! The Inter-Cal Corporation developed Ester-C® Topical to provide the personal care industry with a way of fortifying any skin, lip, hair or sun care product with a stable form of vitamin C that penetrates.

New Ester-C® Topical has a shelf life of at least two years and retains superior stability in oil/water emulsions typical of cosmetic formulations. It is also non-acidic and free of chemical derivatives, like ascorbyl palmitate or ascorbyl phosphates, and effectively penetrates deep down into the skin's layers to help produce collagen and other support structures.

Warning: Cosmetics containing ordinary vitamin C may not be effective for skin maintenance and repair.


  • Stable so it lasts
  • Penetrates to deep layers of skin
  • Promotes collagen production
  • Can be added to any personal care product

New Ester-C® Is The First To Last

Ordinary vitamin C is prone to oxidation and decomposition because it's unstable in water. Since most cosmetics are complex emulsions containing oil and water, ordinary vitamin C can't possibly remain stable.

With new Ester-C® Topical, cosmetics makers can add high concentrations of a stable form of vitamin C to their products to achieve:

  • new levels of stability and penetration
  • the full potential of this essential nutrient's benefits
  • all the vitamin C the product starts out with
  • all the essential minerals (calcium, zinc, and others) that work
  • synergistically with vitamin C.

Inter-Cal's breakthrough discovery sends concentrations of stable Ester-CŪ directly into the skin, making it healthier - naturally!

Not Even Orange Juice Retain Its Vitamin C As Long

To prove that Ester-C® Topical achieves greater stability than ordinary vitamin C, scientists at Inter-Cal pioneered laboratory and analytical methods that gauge the stability of vitamin C liquids, topicals and cosmetics. Extensive accelerated tests revealed the remarkably long shelf life of the Ester-C® Topical... and the remarkably short shelf life of ordinary vitamin C. To understand the stability concept, consider the vitamin C in your orange juice. You buy it "fresh" at the market. But as this chart shows, its vitamin C content deteriorates very rapidly. By contrast, the vitamin C in Ester-C® Topical lasts over two years with a potency of 90%.

Cosmetics With Ordinary Vitamin C Lose Most Of Their Vitamin C Content Within A Month

Contrary to the hype, most vitamin C cosmetics and topicals on the market today fall far short of their promises, many delivering less than 0.02% Vitamin C content. One liquid product that has capitalized on the vitamin C cosmetic craze starts out with about 10% vitamin C, but quickly oxidizes right in the dropper bottle and turns dark yellow. This means the vitamin C is being degraded, as this chart shows. Another product starts off with about 4.5%, then degrades even faster. Even under the best circumstances, these serums degrade rapidly. The formulation and metabolite composition of Ester-C® Topical are very different from any other vitamin C product. The composition of this liquid concentrate is unique and a new patent has been applied for. The Ester-C® mineral ascorbate/metabolite complex that goes into this liquid concentrate is already protected by U.S. and international patents. With the invention of Ester-C® Topical, Inter-Cal has achieved what cosmetic and dermatological scientists have labored over - and dreamed of- for years.

Consumers Report Great Improvement To Skin

Infiltrating the largest organ of the human body and reaching its deep dermal layers is key to stimulating the renewal of cells. Many attempts have been made, but the results have been disappointing due to poor formulation and poor vitamin stability. Scientists at Inter-Cal set out to prove that Ester-C® Topical could reach down to deep layers of the skin where collagen and other important support structures are produced. In an independent test, Ester-C® Topical (14% vitamin C) and a cream containing 1% Ester-C® Topical were applied in a randomized pattern to eight sites on the skin of the inside forearms of five subjects. The test showed that vitamin C from both were able to penetrate the skin barrier to access the cells and tissues involved in the maintenance and repair of skin.

The true measure of Ester-C® Topical's effectiveness came in a controlled test using 39 volunteers. Participants in the study discontinued use of other creams and lotions, and applied 2% Ester-C® Topical cream twice a day. The women - predominantly middle-aged - evaluated the cream for four to five weeks, using it on the face, hands, legs, heels and elbows. Most were "medium" complected and had "dry" skin. Rough and/or chapped skin was reported to be the most common skin problem. Split skin and acne were also frequently noted at the start of the survey. The results:

Consumer Comments:

"it healed my rough skin and heels"
"it soothed my hands right away"
"it had a lasting hydrating effect on my skin"
"it was very soothing"
"it improved my alligator skin a lot"
"it made my skin look healthier"
"I consider it a miracle ointment. No other moisturizer or cortisone creams worked like this one."
"My skin is much softer. I had people feel both arms without telling them why. Everyone said the skin on my left arm (where I applied the product) felt softer and moister."
"It protected my skin even in the pool and hot tub at the gym. The rest of my skin dried up with the chlorine, but my legs and heels are soft and supple."
"My hands are in dishwater eight hours a day, and the cream seemed to last longer than hand lotion."

The Last Word On Health And Beauty

Free-radical damage from aging, smoking, drinking, UV radiation and chemical pollutants deplete the body's natural antioxidant defenses, damage elastin and other support structures, and are thought to produce DNA mutations that can lead to skin cancer. When skin is short on vitamin C, it becomes vulnerable to free-radical damage and can't produce enough natural collagen - the body's intercellular cement. Now, with the discovery of Ester-C® Topical, many exciting products are on the way-creams and lotions for face, hands, and body; lip protectors; cleansers; suntan/sunscreens; and shampoos and conditioners - all with a highly stable form of vitamin C that both penetrates and lasts.

Ester-C® Topical lasts and penetrates.
