After a summer of sun damage, and then carefully sunscreen skin also need to be remedied. In the different stages of skin oxidation, melanin formation and deposition, different components should be selected to correspond with each other in order to achieve whitening effect. Whitening products have not worked, it is likely that the ingredients you choose are not right. The reason for skin blackening is that tyrosinase oxidizes melanin to deposit in keratinocytes, which can prevent skin from blackening by preventing oxidation, inhibiting deposition and metabolism of keratinocytes.
Do you know why you turn black?
As we all know, melanin is the main cause of skin darkening. Melanin needs a series of complex metabolism to form. One of the decisive procedures is that tyrosinase transforms into melanin through oxidation process. At last, melanin is handed over by melanocytes to keratinocytes to complete the final step of skin blackening. Since tyrosinase can be transformed into melanin through oxidation, the first thing we think about is to prevent it Oxidation of this process! So through antioxidant whitening has become the most common way of whitening. In addition to preventing oxidation, we can also directly remove the important element in the oxidation process - tyrosinase! Or simply let tyrosinase stop working normally, so melanin can not be formed.
The most popular whitening ingredients
The most common whitening ingredient may be vitamin C, also known as ascorbic acid, which can inhibit melanin synthesis, reduce melanin, improve collagen content, improve skin color, reduce vascular permeability to reduce inflammation, and have good effect on skin inflammation and erythema. However, due to its instability, it is easy to be oxidized, or decomposed by light, so most brands choose to use its more stable derivatives - AA2G, 2-o-ethyl ascorbic acid, 3-o-ethyl ascorbic acid to make whitening products, which can solve the problem of melanin deposition and adapt to the black skin girls that have been deposited for many years.
The choice of skin care products depends on the ingredients. These ingredients can whiten skin
Not only vitamin C, but also some other antioxidants, such as polyphenolic resveratrol, catechin, lycopene, Pycnogenol, curcumin, coenzyme Q10, green tea extract and Aesculus extract.

If you have been accumulating melanin for many years and are ready to whiten through antioxidant, please pay attention to the antioxidant ingredients mentioned above. It has been found that the dullness and pigmentation of skin color are not only due to the formation of melanocytes and keratinocytes, but also due to the change of dermis. In particular, fibroblasts can greatly affect pigment deposition.
