Vitamin B3 (niacinamide)
Niacinamide: Vitamin B at its Best

Proven to: Increase production of ceramides and fatty acids -- two key components of your skin's outer protective barrier. "As that barrier is strengthened, skin is better able to keep moisture in and irritants out—making B3 a great ingredient if your complexion is dry or sensitive," says Leslie S. Baumann, MD, director of the University of Miami Cosmetic Medicine and Research Institute. In one study, a moisturizer with niacinamide improved the flushing and blushing of rosacea, a common condition that can worsen with age. Another B3 skin care benefit: It inhibits the transfer of pigment to skin cells, minimizing dark spots.

What is Niacinamide:
Niacinamide, is the active component of vitamin B3.When vitamin B3, or niacin, combines with amino acids of another molecule, the chemical reaction produces niacinamide, Niacinamide is a potent cell-communicating ingredient that offers multiple benefits for aging skin. Niacinamide can improve skin's elasticity, dramatically enhance its barrier function, help erase discolorations, and revive skin's healthy tone and texture.

  • Apply Niacinamide topically has been shown to benefit skin color, decrease melanin synthesis, suppresses hyper-pigmentation, and decrease inflammation and itching.
  • It has been shown to increase ceramide and free fatty acid levels in skin, prevent skin from losing water content, and stimulate microcirculation in the dermis
  • It also has a growing reputation for being able to address skin discolorations (often in tandem with other proven skin-lightening agents such as vitamin C and glucosamine) and to reduce acne.
  • The biochemical effects of Niacinamide is to increase synthesis of collagen and to increase ceramide and free fatty acid levels in skin,
  • Topical application of Niacinamide also decreases UV-induced skin cancers and prevented immuno suppression by UV irradiation.
  • It definitely belongs on the A-list of great skin-care ingredients regardless of your skin-care concern. 

 

Vitamin B5 (provitamin)
  • Anti-Aging Properties: It soothes, softens and moisturizes the skin, reducing the appearance of fine lines and wrinkles. The key with Panthenol is keeping that moisture underneath the surface of the skin. This moisture absorption has the effect of “filling out” the area to which it is applied, naturally stretching the skin, erasing fine lines around the eyes and mouth and reducing severity of wrinkles.
  • As a skin softener Panthenol is used to smooth the skin, It provides suppleness, offering plumping and moisturizing
    benefits that penetrate the upper layer of the skin's surface. 
  • Its exfoliating properties fight free radicals and promote new skin cells to consistently  regenerate, offering a more youthful, fresh appearance.
  • It has healing properties, it is effective in soothing and moisturizing dry skin and healing cracked skin.  It has also shown to help in the treatment of many skin disorders and afflictions. It protects the skin against sunburn, acts as an anti-inflammatory agent. It  helps the skin and other body tissues maintain optimal health and promotes healing of tissues as well as taking part in metabolism of fats, proteins and carbohydrates, leading to healthier tissues, cells and organs.
  • When used as part of a daily skin care maintenance system, Panthenol can make a big difference in the overall
    look of your skin.
Vitamin C (l-ascorbic acid)
  • It is a potent anti-oxidant -- protects skin from oxidative damages.
  • It has anti-aging effects -- improves skin elasticity by enhanced collagen production,
  • It can avoid hyper pigmentation including age spots.
  • It has anti-inflammatory and soothing effects.
Vitamin C is an essential component in the body’s production of collagen and a potent antioxidant that can help rejuvenate aged and photo damaged skin. While vitamin C is an important nutrient for overall health, little reaches the skin when orally ingested. As levels of vitamin C in the skin decline with age, replenishing levels directly in the skin can help combat collagen degradation and oxidative stress. Results from clinical trials show that when applied topically, vitamin C promotes collagen formation and mitigates the effects of free radicals, helping to maintain firm and youthful skin.
Vitamin C (Magnesium Ascorbyl Phosphate )
    Magnesium Ascorbyl Phosphate (MAP) is a more stable form of Vitamin C,
  • It will be transformed by the skin enzymes into Ascorbic Acid (vitamin C),  and will stimulate collagen synthesis.
  • as an anti-oxidant agent, vitamin C scavenges and destroys reactive oxidizing agents and other free radicals.
  • It provides important protection against damage induced by UV radiation.
  • It is a skin lightener, it suppresses  pigmentation. it also improves skin elasticity, decreases wrinkles by stimulating collagen synthesis, reduces redness, promotes wound healing.
  • Because body control mechanisms limit the amount of ingested vitamin C available to skin, topical anti-oxidant therapy becomes an efficient way to target vitamin C directly to the skin.
Vitamin e (Tocopheryl acetate )
What is Vitamin E?
Tocopheryl acetate is the ester of Tocopherol (q.v.) and acetic acid and is classified as both an ester and heterocyclic compound. It is used as an antioxidant and a skin-conditioning active and is known by its more common name, Vitamin E. Vitamin E has been a hotly discussed topic in skin care for some time, but recent scientific research is proving its ability to assist the skin in various ways and showing that it has a very beneficial effect in helping prevent the signs of premature ageing.

What does Vitamin E do?
Scientific studies show us that Vitamin E (or often known as, Tocopherol) has very specific benefits to the skin:
  • It protects the skin from environmental pollution
  • It has a protecting action against UV radiation although it cannot be classed as a sunscreen
  • It is an excellent moisturizer
  • It is an anti-oxidant
  • It contains powerful anti-inflammatory action and this can prevent the signs of premature ageing, as inflammatory conditions in the skin is a leading cause of skin ageing
  • It has excellent wound healing properties.
  • Apart from all of these excellent qualities, vitamin E also enhances and helps with the penetration of other compounds into the skin and is itself well absorbed by human skin.
Vitamin E and Sun Exposure, Environmental Pollution and Free Radicals
Vitamin E has a natural affinity to the skin but the amount of vitamin E is reduced in the skin when exposed to sunlight. Environmental pollutants, as well as oxidative material in the body, cause the formation of “free radicals” which are unpaired oxygen molecules, which wreaks havoc on the cells, and cause extensive damage, which can result in premature ageing. Vitamin E is a very effective antioxidant, chemically mediated by the phenolic OH group of the chromane ring, and helps to remove the formed “free radicals” and thereby ensures that oxidative damage is lessened and decreased, by disrupting the chain reaction caused by the free radicals.

Vitamin E and Sun Damage to the Skin
UV radiation from the sun is what causes us to tan, and helps the body to make its own vitamin D, yet exposure to the rays also cause an array of negative reactions in the skin. The first and most well known in the short term is sunburn (erythema) which leads to degenerative changes within the cell, causing age spots and leading to the loss of elasticity, which in turn will result in dry coarser skin, as well as wrinkles and lines.

Another factor that must be considered with UV radiation from the sun is that it causes the skin to become photosensitive and may also cause cancerous growth – starting with actinic keratosis or solar keratosis and then developing further to basal cell and squamous cell cancer, as well as malignant melanoma.

When vitamin E is applied to the skin, a reduction of erythema, sunburn cells, chronic UV-B–induced skin damage, and photo-carcinogenesis is experienced It should be noted however that Vitamin E does not itself have a sunscreen action.

While there is no absolute protection from the sun, cosmetics and moisturizers containing antioxidants, such as Vitamin E, Vitamin C and Beta-Carotene, can counteract damage to cell membranes, DNA, and skin proteins due to oxidation caused by sunlight. These materials don’t work like sunscreens, but they help minimize the damaging reactions in the skin, especially when used in conjunction with sunscreens. When vitamin E is combined with vitamin C, and applied to the skin, it helps to reduce the formation of sunburn cells and offers good photo-protection.

Other studies have also shown that vitamin E protects the fibroblast in the skin – these are the cells that make collagen, glycosaminoglycans, as well as the elastic fibers and glycoproteins found in the extracellular matrix of the skin.

It is also important to remember that when exposing the skin to the sun – the resultant burn or tan is an inflammatory reaction of the skin, and in the quest for achieving a youthful looking skin, it is of prime importance to prevent and to reduce any inflammatory conditions.

Moisturizing Effect of Vitamin E
The topical application of vitamin E has also proven to be effective in reducing sun-induced skin wrinkling and has excellent skin moisturizing properties, also helping to prevent trans-epidermal water-loss by the skin, thereby increasing the natural moisture content of the skin.

Helping Prevent Premature Skin Aging, Excessive Cross-linking and DNA Degeneration
Another factor that plays a major part in skin ageing is cross-linking of protein that occurs in the skin – which is even more prevalent when the skin is subjected to UV radiation. In this case, vitamin E has also proven to be effective in preventing excessive cross-linking and resultant ageing, as well as protecting the natural enzymes in the skin.
As we age the degeneration of DNA – which carries the blueprint of our cells, can occur, and such damage to the DNA can also result not only in skin problems, but also in premature aging. It has been shown that topical application of vitamin E also prevents the degeneration of DNA, especially when compromised by photo-damage.

Vitamin E as an Antioxidant
Vitamin E is one of the best fat (lipid) based antioxidants. Oxidative stress causes free radicals, and if they are not reduced or eliminated, they cause deterioration of the cells. This oxidative stress is also caused by normal cell metabolism, but is exasperated by a variety of environmental factors, including UV radiation, pollution, tanning, smoke, heavy-metals in the environment. Vitamin E protects the cells and cell membranes from free-radical and environmental oxidative stress.
Vitamin E is normally found in the skin, but exposure to sunlight has been shown to deplete this extremely important antioxidant and topical application of it boosts the availability of it. Adequate tocopherol levels become increasingly important in mature skin when it has been shown to decrease. Apart from the antioxidant properties, it also helps to moisturize the skin and even more importantly helps with tissue repair, thereby keeping the skin in good condition.

Vitamin E and Wound Healing
In tests done it was found that a solution containing 5% of Vitamin E acetate decreased the healing time required and also that vitamin E increases the breaking strength of wounds. Vitamin E is required for healthy collagen in the skin – which is the support system in the skin and helps the skin to remain firm and healthy.
