Vitamin C: Ascorbic Acid

What is Vitamin C?

Vitamin C is one of the best-researched classes of medical substances. The active form is L-asorbic acid, which reacts very quickly with oxygen. Oxidized vitamin is ineffective and in high concentrations can even lead to the formation of oxygen radicals, which has a detrimental effect on the skin. Pure asorbic acid should therefore only be purchased in the form of a serum with pump dispenser and not as a cream. A serum is a water-like fluid that’s quickly absorbed by the skin surface. The derivatives of vitamin C, on the other hand, are more stable, have the same effect and can be used in creams. At high concentrations, however, contact with oxygen is also problematic here, therefore I recommend a product with a pump dispenser. Examples of derivatives of L-asorbic acid: sodium ascorbyl phosphate, magnesium ascorbyl phosphate, ascorbyl palmitate.

Why does our skin need Vitamin C?

  • Antioxidant: Vitamin C together with vitamin E protects the skin from free radicals.
  • We need vitamin C above all for the collagen and elastin build-up as well as epidermal differentiation

Vitamin C is essential for the formation of collagen (connective tissue). The collagen is needed to firm the skin. If vitamin C is added to a test tube with fibroblasts, it ensures drastic collagen formation. Vitamin C also stimulates this effect on human skin (abstract). In addition, it can reduce acne and pigment spots and acts against rosacea. Clinical studies have shown that the skin of test subjects became more even and firmer after prolonged use of the ingredient. In addition, vitamin C is an antioxidant and can limit UV damage, making it a “must have” ingredient in any cosmetic product.


🍋 In older people, the vitamin C concentration of the skin is significantly lowered regardless of the vitamin C intake through food. Therefore, especially in old age, an external application of vitamin C in the form of creams and serums is recommended to keep the skin healthy.

Vitamin C Deficiency

Acute vitamin C deficiency causes scurvy, the infamous maritime disease of earlier times. As seafarers ate too little fruit and vegetables, this led to an acute vitamin C deficiency for several months. Scurvy causes various symptoms such as skin bleeding, gum proliferation and joint problems, almost all of which are due to defective biosynthesis of collagen. In the worst case, scurvy leads to death due to cardiac insufficiency.

Where are Vitamin C and its derivatives used?

  • Stimulation and regeneration of connective tissue – damage can occur due to age or smoking.
  • Treatment of hyperpigmentation
  • Treatment of acne, rosacea and inflammation
  • Improvement of wound healing and avoidance of scarring
  • Reduction of wrinkles

Laser Treatments – Vitamin C before and after laser treatments

Through the formation of collagen, vitamin C not only plays a role in wound healing, but also in scar formation. This is why L-ascorbic acid is recommended, for example, for pre- and post-treatment in laser applications. The antioxidant properties of vitamin C are also used to protect the skin before and after exposure to the sun.


What to keep in mind with Vitamin C creams and serums

  1. High concentrations: Vitamin C is first effective at a concentration of at least 5%, but too high concentrations above 15% aren’t necessarily advisable, as this can lead to an imbalance between vitamin C and other antioxidants.
  2. Buy vitamin C in a pump dispenser: It ‘s safest to buy pure asorbic acid as well as its derivatives in a pump dispenser so that they are prevented from reacting with oxygen.
  3. Vitamin C serums should be stored in the refrigerator, because when they are opened they can only be kept for the next 3 months.
  4. Good combination with other antioxidants: Vitamin C and vitamin E complement each other perfectly.
