I don't know when it started, the Internet is talking about "morning C and evening A", saying that it can both fight aging and whiten. You have always longed for whitening, but you have ever had this bold conjecture:
The Shangwei C essence on the market is hundreds of times larger, and the Vitamin C tablets in the pharmacy are only three or five pieces. So, is the vitamin C of the pharmacy also able to be smeared on the face as a skin care product? Isn't it easy to turn yellow skin white with just a few cents a day?
Unfortunately, this kind of "wild whitening method" is not easy to use and the effect is not great.
Eat vitamin C and compress vitamin C tablets
Whitening has had little effect
—
Whether you drink lemonade or eat Vitamin C tablets, due to the influence of intestinal transport mechanisms, you can't absorb much into the skin.
Grinding a few dollars of vitamin C pieces into powder on the face can theoretically be white, but it needs to be perfectly done in the following steps:
The first step is to crush the tablets evenly and dissolve them completely in water; this step can be a bit tricky due to the addition of some styling ingredients to the tablets.
Then precisely control the pH of the solution to avoid too high a failure of vitamin C oxidation and too low to irritate the skin; most people will fail at this step.
After doing so, it also needs to be carefully preserved to avoid inactivation of vitamin C oxidation.
With this effort, directly buy a bottle of Vitamin C skin care products, is not fragrant?

Vitamin C skincare products
The effect is stable and well absorbed
Whitening, or it is recommended to use skin care products containing vitamin C ingredients, the brand will use various technical means to maintain the activity of vitamin C, and the whitening effect is more stable.
Bottled skincare products with more than 10% proto-vitamin C content use brown bottles and fill the bottle with an inert gas when encapsulated.
Many vitamin C skincare products add antioxidants (such as ferulic acid) and polyol moisturizers to improve the stability of vitamin C. Studies have shown that among the three moisturizers of ethylene glycol, propylene glycol, and glycerin, the stability of vitamin C is the best when glycerol is added [1].
However, after the opening of The Vitamin C Skincare Products, it is inevitable that they will lose their activity due to contact with the air. If you have concerns about this, you can choose the vitamin C derivative.
Vitamin C derivatives are more stable than vitamin C and have a strong antioxidant capacity similar to vitamin C, inhibiting melanin production and scavenging free radicals from the skin. They are also less troublesome in their preservation, such as VCIP (ascorbyl tetraisopalmitate), AA2G (ascorbyl glucoside), and 3-o-ethyl ascorbic acid, which are three vitamin C derivatives that do not need to be stored from light [3].
Certain vitamin C derivatives are also better absorbed, such as ascorbic acid-6-palmitate and VCIP, which are fat-soluble derivatives that better penetrate the skin [4] and exert greater whitening effects.
If you want to be able to lighten the spots on your face in addition to whitening, then it is recommended to choose vitamin C derivatives with other ingredients to achieve better results.
More ingredient combinations
Whitening spots in one step
The root cause of pigmentation caused by ultraviolet rays, the combination of vitamin C derivatives and other active ingredients, can better accelerate the metabolism of melanin.
Ferulic acid, for example, increases the activity of glutathione transthulase and quinone reductase, and inhibits tyrosinase, which inhibits melanin production [8].
There are also three ingredients that may have a better spotlight effect. It has been found that vitamin C has a photoprotective effect that forms a protective shield outside the skin and neutralizes oxidative stress by donating its own electrons [7]. Vitamin C can help regenerate the oxidized form of vitamin E, which can be used synergistically by a factor of 4 times more photoprotective than each individually, and ferulic acid can improve the chemical stability of vitamin C and vitamin E when used together, and can increase the photoprotective effect of C + E by a factor of 4 by a factor of 8.[12][13]
Since the vitamin C derivative is eventually converted into vitamin C to play a role, the derivatives are mostly designed to increase stability and have consistent physicochemical properties, so the combination of "vitamin C derivative + vitamin E + ferulic acid derivative" may be a reference to assist in whitening the light spots.
It should be noted that the skin care market is mixed, when purchasing, you must look for products with brand and national license to remove freckles, otherwise the money spent is likely to be adrift.
The normal metabolic cycle of the skin is generally about 28 days, if you want to whiten the spots, be sure to start as early as possible + stick to use. Don't try those "wild whitening" methods, use some whitening and spot essences containing vitamin C derivatives to change back to your original skin color as soon as possible!
