1. freckle whitening cosmetics for the skin what help?
Freckle whitening cosmetics for skin color dull, uneven, color spots and other local defects, has a certain improvement effect. Proper use of freckle whitening cosmetics, help to dilute the stain. However, the "face" project is a systematic project. It is not enough to rely solely on freckle-removing and whitening cosmetics. It is also necessary to do a good job in daily sun protection and moisturizing of the skin to keep the skin in a healthy state.
Some skin problems, such as chloasma, freckles, pregnancy spots, etc., are related to hormone levels and genetic factors. They are caused by internal factors in the human body and cannot be solved only by external use of cosmetics.
2. what is the mechanism of action of freckle whitening cosmetics?

Cosmetics with only physical covering refers to the use of physical covering agents, such as titanium dioxide, zinc oxide, talcum powder, etc. or similar white powder, which are applied to the surface of the skin to cover the spots on the skin to achieve whitening The effect, but it does not change the original appearance of the skin.

Others: bisoxol, arbutin, niacinamide, potassium methoxy salicylate, etc.
4. the use of freckle whitening cosmetics should pay attention to what?
Some freckle whitening cosmetics contain certain ingredients to promote exfoliation, which can accelerate the exfoliation of keratinocytes and make the skin look more tender and shiny; exfoliation also helps the penetration of whitening ingredients, the elimination of melanin, and improve the whitening effect. However, it should be noted that the metabolism of the skin's stratum corneum has its fixed cycle. Excessive use of freckle-removing and whitening cosmetics will make the stratum corneum thinner and the skin's tolerance will be weakened. At the same time, due to the reduced skin barrier effect, the skin will be more directly exposed to ultraviolet light, pollutants and other external environments, which will lead to other skin problems. Therefore, the use of freckle whitening cosmetics to moderate, control the amount and frequency.
Consumers should use the product in accordance with the recommended use, dosage and frequency of freckle whitening cosmetics. If consumers use a variety of skin care cosmetics of different brands at the same time, they should also pay attention to the superposition effect between products.
5. the selection of freckle whitening cosmetics to pay attention to what?
In June this year, the State Council issued the "Regulations on the Supervision and Administration of Cosmetics" to manage freckle whitening cosmetics as special cosmetics. Freckle whitening cosmetics must be registered by the State Food and Drug Administration before listing. The approval number format of this kind of products: domestic products are "national makeup special word G2020XXXX", and imported products are "national makeup special word J2020XXXX". The State Food and Drug Administration released the "Cosmetics Supervision" APP in 2019. When purchasing cosmetics, consumers can inquire and check whether the registration information of the product is consistent with the information of the product identification. If not, the source and quality of the product are in doubt. I would like to remind consumers that when purchasing freckle-removing and whitening cosmetics, they should choose regular sales channels and check whether the products are marked with a standardized approval number. Any cosmetics that claim quick-acting whitening or produce freckle-removing and whitening effects immediately after use are suspected of illegally adding prohibited substances such as hormones and heavy metals, which need to be highly vigilant.
In addition, different freckle whitening cosmetics are often designed and developed for different skin problems and suitable for people. Therefore, in the choice of freckle whitening cosmetics, but also according to the efficacy of the product claims, applicable to the crowd, etc., choose products suitable for their own skin characteristics.
