The skin produces melanin and even spots due to various reasons, such as photoaging caused by ultraviolet rays, personal endocrine metabolism, genes, etc.
Sun protection can slow down photoaging and reduce melanin production. In addition, we can prevent skin melanin precipitation and lighten pigments through some whitening methods, including promoting the metabolic rate of stratum corneum renewal, laser, LED light therapy, oral drugs, supplements, etc.
What really whitens skin ?
The pursuit of rapid whitening can cause damage to the skin and even the body. We recommend that everyone adopt a scientific and effective whitening program to achieve safe, long-lasting and deep blackening.
Commonly used whitening ingredients include: vitamin C and its derivatives, azelaic acid, arbutin and its derivatives, tranexamic acid, tranexamic acid, pantothenic acid derivatives, resveratrol, fruit acid and its derivatives, koji Acid, other plant extracts, antioxidants, etc.
Commonly used whitening agents in Japanese and Korean cosmetics include: arbutin, nicotinamide, glabridin, phenethylresorcinol, ascorbic acid (vitamin C), ascorbic acid glucoside, 3-o-ethyl ascorbic acid, Magnesium ascorbyl phosphate, tranexamic acid, potassium methoxysalicylate, bisabolol, etc. Among them, the whitening plant ingredients mainly include oil-soluble licorice extract, structure leaf extract, chamomilla flower extract, etc.
Nicotinamide + Vitamin C Derivative + Nonapeptide
Vitamin C plays a key role in the synthesis of melanin. It can act on tyrosinase and reduce dopaquinone in the process of melanin formation into dopa, so it can inhibit the production of melanin from the source.
The function of nicotinamide is to reduce the accumulation of melanin by inhibiting the transport of melanin to the stratum corneum after melanin synthesis.
When vitamin C and niacinamide are combined, the whitening mechanism will be more complete. Combined with nonapeptide, it can not only lighten spots, even out skin, and brighten skin tone, but is also friendly to sensitive skin. The three ingredients They are non-photosensitive and can be used day and night.
Relatively mild whitening ingredients, nonapeptides and vitamin C derivatives, can be used with confidence. For ingredients that are irritating like nicotinamide, you can choose products with lower concentrations.
What is the best way to brighten skin ?
The mechanism of whitening raw materials is as follows:
By using substances to reduce the activity of melanocytes, the amount of synthesis is reduced.
Chemically reduces the oxidation of L-dopa molecules into pigment compounds.
Reduces erythema caused by ultraviolet radiation through anti-inflammation.
By reducing tyrosinase activity. In the production process of melanin, the most critical thing is tyrosinase. If you can effectively inhibit tyrosinase activity, you can have a good whitening effect.
