The ingredients with the best whitening effect, because of the reason of "one white covers three ugliness", many people have a certain pursuit of whitening, and some ingredients in whitening products are specially used for whitening. Let's share the ingredients with the best whitening effect.
Ingredients with the best whitening effect 1 1. Fruit acid
Fruit acid is the most commonly used whitening ingredient at present. Mainly extracted from fruits, glycolic acid extracted from sugarcane has the best whitening effect. Using fruit acid to rejuvenate the skin can remove the over-aged cuticle, help stimulate cell regeneration, and have a good effect on weakening fine lines and epidermal pigments, thus making the skin softer and whiter. Fruit acid is also the most widely used whitening ingredient in the market at present.
Second, kojic acid
It is found in experiments that kojic acid has the most obvious effect among all whitening ingredients. Generally, it is extracted from filamentous fungi such as Penicillium and Aspergillus, which is a toxic cell, so it has not been fully popularized in the market at present.
Third, arbutin
Dried arbutin is also a commonly used whitening ingredient in the market. Arbutin can temporarily reduce the formation of melanin without affecting cell proliferation, so it is safer to use arbutin. Arbutin is mainly extracted from plants, also known as arbutin or myricetin.
Component 2 with the best whitening effect can whiten five components of skin.
The most commonly used vitamin C and its derivatives
Vitamin C (ascorbic acid, the most effective of which is its left-handed and right-handed optical structure, also called L- ascorbic acid) has whitening effect for both internal and external use.
Principle: inhibit melanin synthesis, reduce melanin, improve skin color by increasing collagen content, reduce vascular permeability and reduce inflammation, so it also has a good effect on inflammation and red blood spots.
Safety: Generally speaking, it is safe, but high concentration will have a certain degree of irritation.
Effectiveness: effectiveness
Disadvantages: unstable, easy to oxidize, damaged by light and decomposed.
Homology: VC derivative, milder and more stable. Common ones are VC ether, magnesium/sodium ascorbate phosphate (MAP, SAP), ascorbate glucoside (AA2G) and ascorbate palmitate (AP).
The most practical arbutin and vitamin B3
α-arbutin is effective and stable, and its limited addition is below 7%, generally around 3%, which can inhibit the activity of melanocytes and reduce the production of melanin. Mild effect, low irritation, but occasional adverse reactions. Generally speaking, it is safe and effective.
Vitamin B3, nicotinamide, nicknamed "anti-dermatitis factor", can inhibit the transfer of melanin to keratinocytes, and also has many improvement effects. Experiments show that topical application of 2% nicotinamide for 8 weeks reduces sebum by 23%, reduces pores by 9%, significantly increases collagen, enhances skin barrier, is non-irritating, has stable properties and is easy to prepare. Compared with retinoic acid, it has obvious advantages in improving skin appearance.
Tranexamic acid, chemical name tranexamic acid, is effective for both internal and external use. On the one hand, it can inhibit melanin production, but the most important thing is to stop bleeding, which has a very good effect on chloasma, especially on pigmentation caused by vasodilation and rupture. It is also irritating to some people. People over 55 years old, allergic patients, patients with thrombosis and those with kidney problems should take it orally with caution.
Glutathione (GSH) is also an important antioxidant and a component of whitening needle.
Tangled fruit acid
As an exfoliating agent, fruit acid can quickly exfoliate keratinocytes, and melanin exists in keratinocytes and exfoliates together, thus achieving the purpose of improving skin color. Glycolic acid is commonly used. At the same time, fruit acid can also promote the synthesis of dermal collagen, making the skin more moist and shiny. But it will make the stratum corneum thinner, and the skin is more sensitive to light, which is irritating to some extent, and not everyone can stand it. You can choose to be quick white.
Almighty soybean extract
Soybean essence is almost omnipotent, with excellent whitening effect, which can improve the skin in an all-round way and is suitable for any type of skin without any stimulation.
Principle: inhibit melanin synthesis, reduce melanocyte volume, improve skin quality, resist inflammation and oxidation, promote the increase of dermal collagen, enhance hyaluronic acid synthesis and repair barrier function;
Safety: completely safe, no irritating record;
Effectiveness: effectiveness
Disadvantages: At present, there are few applications, and the soybean ingredients used are generally not whole soybean extracts. It is not easy to obtain in daily life, and it is easy to be destroyed by heat loss.
The twists and turns of "flexor acid"
Kojic acid used to be extracted from Aspergillus, but now it can be synthesized artificially. It is irritating to some extent and may weaken the skin barrier. Use with caution for sensitive skin (azelaic acid, that is, Du Juanhua acid, is also irritating).
Various plant extracts are ideal.
There are many kinds of polyphenols and flavonoids, such as tea polyphenols, grape seed extract, ellagic acid (persimmon leaf extract), mulberry bark extract, angelica, scutellaria baicalensis, dried tangerine peel, Ophiopogon japonicus and so on.
* * * The same characteristics are: they are mild, but due to the complex composition, some individuals occasionally have allergic or irritating reactions. Generally, it is very stable, and has many functions, such as anti-oxidation, promoting collagen synthesis in dermis, so it can be used for anti-aging and anti-saccharification.
At present, the research focuses on plants, but generally speaking, the research is not deep enough, and many components are still limited to in vitro experiments. The clinical research on human beings needs to be deepened, but there is no doubt that they are renewable, available and have great potential, so they are the most promising.
