Ascorbic Acid (Pure Vitamin C)

Pure Vitamin C (*9) — Without Any Additives

Ascorbic acid (*9) is a water-soluble vitamin that is also known as vitamin C. It is a vitamin that is essential for connective tissues such as the skin, tendons, and cartilage, and is required for collagen synthesis. While, of course, it is important for beauty, it is also important for the health of the human body. Many products may claim to be vitamin C, but only those that are 100% vitamin C can be called ascorbic acid.

The Characteristics of Ascorbic Acid (*9)


As an elemental component of good beauty and health

Ascorbic acid (*9) is a vitamin that helps constitute connective tissues such as the skin, tendons, and cartilage. Required for collagen synthesis, it cannot be made in the human body, so an outside source must be constantly replenished.

As ascorbic acid is required for many parts of the body, any vitamin C consumed via diet or supplements is quickly used up by essential organs like the brain or liver. Therefore, any leftover vitamin c would not be enough to supply a very large organ like the skin, even when taking supplements of ascorbic acid. Furthermore, because ascorbic acid is a delicate molecule that has a hard time penetrating the skin, any cosmetic product that is formulated with it must contain a high-level of technology to help absorption (*).

Ascorbic Acid's Effects on the Skin

A High-Level Antioxidant

Ascorbic acid, with its high-level antioxidant power, has a large number of beauty benefits without causing any side effects. From removing active oxygen and preventing premature aging to promoting collagen formation, it is essential for beautiful skin. Among other things, it can smooth out irregularities on your skin, reduce acne marks, and, through the promotion of collagen formation, reduce the appearance of wrinkles.

Which other components go well with it?

Synergistic Ingredients

We recommend combining it with Vitamin E, a compound that removes hydroxyl radicals, a major cause of oxidation and inflammation.

How Are Vitamin C Derivatives Different?

Differences with Similar Components

Vitamin C derivatives aim to improve upon the weaknesses of ascorbic acid (*9) and make it easier for use in cosmetics. In general, they work to improve absorption into the skin and to create enzymatic reactions close to melanin pigments. Because such derivatives are two to eight times larger than ascorbic acid molecules, the usually have a lower concentration than those products that are 100% vitamin C.
In general, vitamin C derivatives (*9) are classified into three groups, depending on the size and nature of the molecule.

Vitamin C Phosphate (water-soluble)

Structure of Vitamin C Phosphate (water-soluble)

Vitamin C Content: 54.7–60.8%

A stable compound that is resistant to oxidation, even when exposed to the air, it exhibits the qualities of original vitamin C by breaking down into smaller components when entering the skin.

Ascorbyl tetra-2-hexyldecanoate (fat-soluble)

Structure of ascorbyl tetra-2-hexyldecanoate (fat-soluble)

With a quite low 15.6% Vitamin C Content

A vitamin C derivative that slowly, over time, penetrates the skin. It works to remove activated oxygen for over 48 hours.

Trisodium Ascorbyl Palmitate Phosphate (water-soluble and fat-soluble)

Structure of trisodium ascorbyl palmitate phosphate (water-soluble and fat-soluble)

Vitamin C Content: 31.4%

Among the vitamin C derivatives (*9), this one has the highest penetration ability. Because it can reach the depths of the skin (*), it is said to be particularly effective in collagen formation.

Why Not Choose Easy-to-Absorb Nano-Encapsulated Pure Vitamin C?

When using an ascorbic acid supplement for skincare, it is most efficient to use a product that has a concentrated amount of active ingredients.
Ascorbic acid is good for the skin, but its delicate nature means that it is unable to enter the stratum corneum or penetrate the skin on its own.
As vitamin C is an ingredient that you expect to see the results on your skin immediately after application, it's best to understand how it is manufactured and how it is expected to penetrate your skin before choosing a product.
Spa Treatment's Ex-Series, with its easy-to-penetrate D.P.D. nanocapsules, are therefore our recommendation.
