What is the principle of whitening


Our skin is the largest organ in the body. Now the stressful life, pollution, poor eating habits and fast pace of life are affecting our whole body and it shows clearly on our skin, causing you to see some dull spots, spots or some hyperpigmentation issues on the skin. Melanin is the main substance that determines skin color.

The biggest major determinant of human skin color is melanin produced by melanocytes, which is found in the basal layer of the epidermis. In melanocytes, tyrosine, one of the amino acids, acts as a substrate to produce melanin by activating tyrosinase. Whitening ingredients generally work by reducing the amount of melanin in the skin. This means that chemicals are added to skin care ingredients to lighten and lighten the skin by reducing the concentration of melanin in the skin. Skin lighteners work by reducing the presence of melanin in the skin. For this reason, there are several possible mechanisms of action: Inhibition of tyrosinase activity: The catalytic action of tyrosinase is inhibited by skin lighteners. Inhibition of tyrosinase expression or activation: Antimelanin-producing agents cause less tyrosinase to be produced or prevent tyrosinase from being activated to its functional form. Eliminate intermediates in melanin synthesis. Preventing the transfer of melanosomes to keratinocytes directly destroys existing melanin by destroying melanocytes. At present, whitening products on the market will add some whitening active ingredients, I listed some, generally as follows:

Kojic acid

Kojic acid powder inhibits the production of tyrosinase in the body and prevents the formation of melanin, and the recommended concentration of kojic acid whitening active ingredient is 1%-4%. as kojic acid soap,kojic acid serum,kojic soap,and so on kojic acid products Extracted from a variety of fungi and from the fermentation process of rice, it is harmless to all skin types and works by inhibiting and preventing the formation of tyrosinase, an amino acid essential for the production of melanin, in addition, more recently, this ingredient has been shown to be superior to other whitening substances.

The body needs exposure to sunlight to produce vitamin D, which is essential for bone health and other bodily functions. However, you should not fully expose yourself for a long period of time, as this can lead to multiple health problems as well as darkening of the skin.
