Vitamin C benefits for Skin whitening

Vitamin C is a water-soluble vitamin that has a lot of biochemical and medicinal qualities. It is also called ascorbic acid or ascorbate. Many natural fruits and vegetables contain vitamin C.Those who lack vitamin C in their body, are given dietary supplements of vitamin C such as sodium ascorbate and calcium ascorbate.

It is a natural antioxidant found in many fruits and vegetables. Citrusy foods are generally known for their richness in vitamin c. Even some animals can synthesize vitamin C on their own. But humans lack the enzyme gluconogamma lactone oxidase which is a key enzyme in vitamin C synthesis in the body. In this case, humans have to gt their required vitamin C from plant and animal sources.

When considering vitamin C’s pharmacokinetics and pharmacodynamic properties, its bioavailability is 100% and very fast; its protein binding capacity is negligible; its half-life and elimination depend on the blood concentration, and it is mainly excreted via kidneys.

Vitamin C is known for its medical qualities in the medicinal and cosmetic industries. In the medical field, vitamin c is broadly used to treat disease conditions such as scurvy. Vitamin C is used in the medicinal industry for many treatments. As vitamin C acts as a cofactor for several enzymatic reactions, it is useful in many therapies as it has antioxidant qualities.

In the cosmetic industry, for many skincare products, vitamin C is used. Due to the fact that its bioavailability is low when administered orally, it is considered a good dermatological administration. And many studies have proven that vitamin C benefits for skin whitening. There is some special property of vitamin C benefits for skin whitening.

What are the vitamin C benefits for skin whitening?

There are a lot of vitamin C benefits for the skin. As it has good medicinal and cosmetic properties, it is widely used in beauty products. Even in face massage therapies, they use vitamin C serum for some cosmetic purposes.

 Vitamin C is used for a lot of purposes.

  • To remove acne scars
  • To remove dark spots
  • To treat under eye dark circles

  • To lighten the skin tone.

Because of the vitamin C benefits for skin whitening, it is used in many whitening skincare products as well. To enhance the skin whitening property of vitamin C, some other ingredients such as vitamin E, Niacin, Glutathione, almond oil, honey, yogurt, papaya, potato, tomato,  oatmeal, turmeric, etc.

What quality of vitamin C benefits skin whitening?

Vitamin C has a lot of chemicals, pharmaceutical, and cosmeceutical properties. Because of the good cosmetic properties of vitamin C, it is widely used in cosmetic products. But also due to these properties some may get skin irritations at the same time. To use a vitamin C product wisely, you should have proper knowledge about its actions. The chemical properties of vitamin C are very special in its mechanism of action.

Chemical properties of vitamin C:

  • It is an asymmetrical molecule that has the structural formula of C6H8O6.
  • Molecular weight is 176 atomic mass units
  • The melting point is 190- 192C
  • Density is 1.65g/ cubic cm
  • Soluble in water and alcohol.
  • Insoluble in chloroform, benzene, and ether
  • Colorless or slightly yellow color solution
  • pKa value is 4.2 and 11.6
  • pH for a 5% (W/V) solution of water is 2.2- 2.5
  • Therefore, it has acidic properties.
  • Oxidize easily and even destroyed by light, high temperature, alkali conditions, humidity, copper, and other heavy metals.

Pharmaceutical and cosmeceutical properties of vitamin C:

There are a lot of advantages of vitamin C. it acts as a cofactor for many enzymes inside the body. Therefore, vitamin C is considered as an essential nutrient to our body.

 In the medicinal and pharmaceutical field vitamin C is given for those who suffer from vitamin C deficiency. But here we will focus on the advantages of vitamin C in skincare. To act as a whitening agent, vitamin C has a lot of cosetic proprties. They are,

  • Antioxidant agent for human skin
  • Prevents photo-aging
  • Prevents hyperpigmentation
  • Involves in collagen synthesis
  • Antiinflammatory actions

Vitamin C as an antioxidant for human skin:

A major property of vitamin C benefits for skin whitening is its antioxidant action. It involves the enzyme group which protects the skin from reactive oxygen species (ROS). If you wonder what ROS is, they are the products of oxygen synthesized on the skin due to UV radiation exposure of the skin.

  • Superoxide ions
  • Peroxides
  • Singlet oxygen

 Vitamin C is soluble in the aqueous compartment of the cells. Therefore, it helps to reduce oxidative stress by donating electrons to neutralize the free radicals formed by ROS. the oxidized forms of vitamin C are comparatively neutral in reactivity.

Anyway, these oxidized forms of vitamin C can be transformed into normal vitamin C back in the presence of a glutathione cofactor. This reaction is regulated by the enzyme, dehydroascorbic acid reductase.By the way, due to this series of reactions, the availability of vitamin C on the skin gets reduced with UV exposure.

Prevention of photoaging by vitamin C:

Exposure to UV radiation causes the formation of reactive oxygen species (ROS) on the skin as explained above. These ROS can damage the skin cells through a series of reactions. The damages can be occurred to,

  • Cellular DNA
  • Cell membrane
  • Cellular proteins

ROS not only damage the organelles but also interfere with the physiology of the cells. It causes collagen breakdown by interfering with matrix metalloproteinase enzymes. Oxidative stress caused by ROS can lead to inflammations on the skin as well as ageing. Vitamin C is effective in this antiaging property.

It is effective against both damages caused by UVA and UVB radiations. UVA can penetrate deeper into the dermis than UVB. Thus, UVA is responsible for destroying collagen, elastin, proteoglycans, and other cellular organelles. UVA can increase the risk of melanoma with these actions.

Not only UVA, but UVB also can be destructive. It can cause sunburns, skin cancers, and epidermal mutations which are serious. Sunscreen products only have about 55% protection from these harmful UV rays. Therefore, vitamin C plays a major role in preventing damages done by free radicals on the skin.

Vitamin C can be more efficient when mixed with vitamin E in this scenario. As vitamin E is lipid-soluble it’s a lipophilic antioxidant. Thus, the mixture of vitamin C and Vitamin E shows a synergistic anti-oxidant action. They reduce cell apoptosis and thymine dimer formation. However, the combination of vitamin C, Vitamin E, and ferulic acid are used in the prevention of chronic photodamage and skin cancer.

Prevention of hyperpigmentation by vitamin C:

Vitamin C is considered a depigmentation agent. It interferes with the melanogenesis from melanocytes in the occasions where melanogenesis occurs rapidly due to toxic substances.

Tyrosine is a major constituent of melanin. Therefore vitamin C blocks the action of tyrosinase by acting on the active sites as competitive inhibitors. This reduces the melanin synthesis by melanocytes. As vitamin C is an unstable compound, its action can be enhanced by the inclusion of depigmentation agents such as soy and liquorice.

Vitamin C for collagen synthesis:

Vitamin C is a key factor in the collagen synthesis process. The enzymes prolysyl hydroxylase and lysyl hydroxylase regulate collagen synthesis by stabilizing and cross-linking the collagen molecules. And vitamin C acts as a cofactor for these two enzymes.

Vitamin C also involves collagen synthesis by stimulating lipid peroxidation. The end product of this lipid peroxidation is malondialdehyde which triggers the collagen gene expression. It activates the transcription of collagen synthesis and stabilizes the procollagen mRNA.

Even the disease scurvy occurs by impaired formation of collagen protein in the body. Vitamin C is given as a treatment for this condition as it enhances collagen formation.

Anti-inflammatory actions of vitamin C:

Vitamin C has antioxidant properties as explained above. In this scenario, oxidative stress triggers some cellular activities mediated by transcription factors. These transcription factors include ROS upgrade transcription factor activator protein (AP1) which increases the matrix metalloproteinase (MMP) production. This MMP production causes collagen breakdown. Oxidative stress induces nuclear transcription factor kappa B (NFKB).

Vitamin C inhibits NFKB. This prevents the activation of many pro-inflammatory cytokines such as,

  • TNF- alfa
  • IL1,
  • IL6
  • IL8

This action prevents inflammatory actions on the skin such as acne, rosacea. Vitamin C fastens wound healing and prevents post-inflammatory hyperpigmentation as well. This is why vitamin C is used in acne prevention and curing products. In many face care products, vitamin C is included.

How can I find any product of vitamin C benefits for skin whitening?

Skin whitening products include vitamin C as a major constituent. These vitamin C skin whitening products exist in different dosage forms. But mostly the products are semi solid liquid form. These topical products of vitamin C are in a wide range as,

  • Creams
  • Moisturizers
  • Vitamin C serum
  • Transdermal patches

Vitamin C serum:

The vitamin C serum contains the colorless fluid of active vitamin C. But as active vitamin C is very unstable, it gets destroyed with exposure to sunlight. After oxidization, it converts into dehydroascorbic acid. This end product is yellow.

Vitamin C serum is kept stable by maintaining its PH level at 3.5. As uncharged molecules pass through cell membranes better, vitamin C is highly absorbed through the stratum corneum better with uncharged molecules of it. But the efficacy of vitamin C serum can be directly proportional to the concentration of active vitamin C in it. And that is 20%. After administration of a maximum topical concentration of the serum, its half-life is 4 days. Therefore, effective photoprotection can be achieved by applying it subsequently every 8 hours. The combination of tyrosine, zinc, and vitamin C has shown enhanced efficiency in UV protection

Some of the popular vitamin C serum products are,

  • Dr. Dennis Gross C+ collagen Brightens and firm serum

Do vitamin C patches work? yes because of the quicker absorption of vitamin C through the dermal layer this method is effective. But in the case of high molecular weight ingredients, they can be low in dermal absorption. These are even prescribed as food supplements in vitamin C deficiency conditions.

When a transdermal patch is attached to your skin,

  1. Its drug content is released into the stratum corneum
  2. Drug diffuse through stratum corneum via tortuous intercellular lipid pathway
  3. Drug partition from the lipid stratum corneum into the aqueous viable epidermis.
