As the saying goes, one white covers three ugliness, and whitening is the career and goal pursued by many women all their lives.
In order to whiten the skin, most people will choose to use whitening skin care products.
So, can whitening skin care products help us whiten? In addition to using skin care products, can you whiten yourself with what?
Before answering these questions, we should first understand how skin color is determined.
Who decides your skin color?
First of all, the main factor determining skin color is melanin, which is produced by melanocytes.
Melanocytes have the activity of synthesizing complex aminidase, which can start the production and storage of melanin. The produced melanin is transported to keratinocytes and gradually metabolized.
Our genetic genes determine the activity of melanocytes and their ability to store melanin. In other words, genetic genes are the basis for determining skin color and whether it is easy to turn black.
Secondly, a variety of acquired factors can act on melanocytes to promote melanin synthesis and cell volume increase, and also lead to skin blackening and color spots. These acquired factors include ultraviolet rays, inflammatory reaction, skin aging, etc.
If we want whitening, it is actually to inhibit and block the series of processes of melanin production and metabolism.
The good news is that there are indeed many ingredients that can achieve this effect.
Revealing the Secrets of Common Whitening Ingredients
The first category: arbutin, kojic acid, trans-sulfuric acid, etc.
These components can inhibit the activity of complex aminidase, a key enzyme in melanin synthesis. As the activity decreases, melanin production naturally decreases.
However, it should be noted that arbutin is photosensitive and is recommended to be used at night. Kojic acid is sensitive to light and heat and is also recommended to be used at night. Chuanming acid has strong stability and does not irritate skin, but its strength is weak.
The second category: vitamin E, vitamin C derivatives, retinol, etc.
Oxidation also plays an important role in the formation of melanin, so adding the above antioxidants can also reduce the formation of melanin.
However, the stability of these components is relatively poor, and the effect and strength are also relatively weak.
The third category: nicotinamide, etc.
Melanin needs to be transported to keratinocytes after production. When this transportation process is blocked, it can also play a whitening role.
Nicotinamide can inhibit melanin migration to keratinocytes, and its effect is strong. It can also be used to resist inflammation and repair barriers.
However, its irritation is strong, and some people do not tolerate it. Tolerance needs to be gradually established. There are also a few people who will have hair increase and other phenomena when using it.
The fourth category: fruit acid, salicylic acid, etc.
When melanin has been formed and transported, we can also remove freckle and whiten skin by accelerating metabolism and stripping stratum corneum.
Fruit acid and salicylic acid are the most commonly used components, which can promote melanin metabolism and exfoliate cutin, but both have certain irritation and need to be gradually tolerated.
After reading the above, I believe everyone has a certain understanding of the effective whitening ingredients.
No matter what kind of skin care products contain, in order to make it play its greatest role, we must stick to it.
Warm Tip: As most whitening products are irritating, it is recommended that people with sensitive skin should choose carefully. Improper use may cause further damage to the skin barrier.
Is there any way to whiten what?
If you want to keep your skin white, what else can you do besides using whitening skin care products?
The most basic is moisturizing and sun protection.
Moisturizing the skin is conducive to maintaining and repairing a good skin barrier.
Sunscreen is even more important, because ultraviolet rays are an important cause of melanin production. If you don’t do a good job of sun protection, using more whitening products is equivalent to doing useless work.
You can use hard sun protection methods such as holding umbrellas, wearing hats and masks, or you can use sunscreen. At the same time, it should be stressed that sun protection is equally important in summer and winter.
In addition, laser therapy such as photon rejuvenation, laser and water injection can also be carried out.
The former mainly uses specific strong pulsed light energy to pass through the skin and selectively act on vascular pigments, etc. to achieve the effects of whitening skin and stimulating collagen proliferation.
If necessary, it is recommended to consult and treat formal institutions. The latter injects hyaluronic acid and whitening ingredients into the dermis layer to improve skin quality and whiten and brighten the skin at the same time.
As for oral drugs, whitening pills, whitening needles, etc., it is recommended that everyone use them carefully.
Common effective ingredients in oral drugs, such as vitamin C, nicotinamide, tranexamic acid (tranexamic acid), glutathione, etc., have certain effects on whitening, but after all, they are oral drugs and may be accompanied by related adverse reactions more or less, so please guide the medication after evaluation by professional dermatologists.
[Whitening Pills] have not been officially approved in China, Strictly speaking, it belongs to the “three noes” product, and the dosage of the added drug ingredients is not clear, which has the risk of causing serious adverse reactions. The drug ingredients in the “whitening needle” do not have the clinical indication of “whitening”. Large dosage may cause dizziness, nausea and vomiting, kidney stones, increased risk of thrombosis and other hazards, which need to be vigilant.
