As a powerful antioxidant and whitening agent, ascorbyl tetraisopalmitate has anti-acne and anti-aging capabilities. It is an effective oil-soluble vitamin C ester. Like other forms of vitamin C, it helps prevent cell aging by inhibiting collagen cross-linking, protein oxidation and lipid peroxidation. It also works synergistically with the antioxidant vitamin E and shows excellent transdermal absorption and stability. Many studies have confirmed that it can have skin lightening, light protection and moisturizing effects on the skin. It can be found in various skin care products such as anti-aging serums, eye care, skin lightening gels and lotions/creams.
Like all forms of vitamin C, ascorbyl tetraisopalmitate:
1) Fades dark spots and discoloration
2) Increase UV light protection to help reduce sun damage
3) Promote the production of collagen and keep the skin firm
4) Fight free radicals that cause premature aging
However, because it penetrates the skin faster and easier, the effect is better.
The skin is the largest but most sensitive organ of the body. As you age, reactive oxygen species or ROS begin to accumulate in your body. Oxidative stress also increases with exposure to environmental pollutants and ultraviolet radiation. It will increase the production of melanin, hinder the synthesis of collagen, and accelerate the decomposition of existing collagen. As a result, your skin will be covered with wrinkles, age spots and uneven pigmentation. It is known that ascorbic acid and its derivative molecules act at the cellular level to quench ROS. Compared with simple ascorbic acid, ascorbyl tetraisopalmitate can play a longer time (up to 40 hours) of free radical scavenging effect. On the other hand, ascorbic acid causes the maximum elimination of free radicals within 30 minutes, but not afterwards.
Signs of aging include wrinkles, uneven skin tone, rough skin, and decreased skin brightness. The underlying mechanisms of skin aging include decreased collagen production, increased light damage, and decreased skin moisture.
Ascorbic acid and its derivatives help improve the appearance of the skin and exert anti-aging effects because they can improve cell survival, skin hydration and collagen synthesis.
Ultraviolet rays increase inflammation of the skin's surface layers (epidermis and dermis). It destroys the core (DNA) of skin keratinocytes (skin cells) and causes them to disappear quickly after a process called apoptosis. In addition, UV rays increase the thickness of your skin and increase the production of skin melanin. Ascorbyl tetraisopalmitate achieves excellent penetration in skin keratinocytes and helps them to resist the harmful effects of ultraviolet radiation. Compared with pure vitamin C, the survival rate of cells treated with ascorbyl tetraisopalmitate increased by 30%.
Melanin is a black pigment that protects your skin from UV rays. However, a large amount of this pigment can cause darkening and uneven skin tone. Most skin whitening ingredients have the effect of reducing melanin, mainly because they can reduce the activity of tyrosinase, which is a key enzyme for melanin synthesis . Ascorbic acid has no tyrosinase inhibitory activity. On the contrary, it reduces the production of melanin by strengthening the body's inherent antioxidant mechanism, thereby preventing the production of melanin due to ultraviolet radiation. Laboratory test results show that treating skin cells with ascorbyl tetraisopalmitate can reduce melanin production by 80%.
Collagen is one of the most important proteins in the skin. It is responsible for maintaining the basic skin structure and giving the skin a soft and youthful appearance. As you age, your skin begins to lose its collagen reserves due to exposure to environmental toxins and pollutants. One of the several culprits that increase the breakdown of collagen is matrix metalloproteinases (MMP). This enzyme causes rapid breakdown of skin collagen. Treating skin cells with ascorbate-based products can increase collagen synthesis by 8 times. Compared with simple ascorbic acid, ascorbyl tetraisopalmitate increases skin collagen synthesis by 50%. In addition, it also causes a significant decrease in the activity of collagen degrading enzymes.
1) The residence time in skin cells is 40 to 80 times that of l-ascorbic acid, and the effect is four times than that of Vc
2) Reduce transdermal moisture loss, increase skin elasticity, and significantly improve skin texture
3) It is a proven vitamin C precursor that can effectively inhibit skin pigmentation caused by UVB
4) Transdermal absorption is faster than other forms of vitamin C3-the concentration of ATIP absorbed by cells is 10 times that of l-ascorbic acid
5) Due to its fat solubility, it allows faster transdermal absorption than other forms of vitamin C
6) Provide better stability
7) Reduce irritation
8) Significantly improve facial pigmentation
9) Reduce transdermal water loss
10) Increase skin elasticity
11) Significantly improve texture and wrinkles.
In short, ascorbyl tetraisopalmitate is an effective anti-aging, anti-oxidant, melanin-inhibiting and collagen-promoting skin care ingredient, with impressive safety. It is more effective, safer and more effective than the usual vitamin C preparations.
