Whitening products have always been an indispensable gift for girls, and vitamin C is a common ingredient in whitening products. However, even if the product contains vitamin C, it may not be able to achieve whitening effect. Therefore, when we choose vitamin C whitening products, there are certain requirement. Remember not to only focus on whitening, skin problems like lack of water, fine lines etc. should also be paid attention, so that you can’t really achieve even whiteness!
Combined with cell repair function
Vitamin C has an antioxidant effect, which promotes metabolism and restores oxidized melanin to achieve blemishes and whitening effects. In addition, it also promotes the proliferation of collagen. Increase the absorption of vitamin C can enhance the elasticity of your skin.
Choose vitamin C items with high stability
Vitamin C is easily oxidized and yellowed when exposed to air, and its efficacy is greatly reduced. Therefore, not all vitamin C has a whitening effect. If the concentration of the vitamin C product is indicated as 10%, the true infiltration to the muscle base may be less than 10%, and it will not work. Therefore, when choosing a whitening product, you must choose a high-vitamin C component.
The concentration ratio must be at least 10%
The higher the vitamin C content, the more irritating to the skin. And scientific research has found that external use of vitamin C can make skin cells absorb 20 times more than the nutrition you can get from food with vitamin C. In the case of external application of vitamin C, the concentration ratio must be at least 10% with high stability, so that the nutrition can 100% infiltrate to the muscle base and achieve whitening effect.
Choose a small molecule product
In addition to concentration and stability, when selecting whitening products, you should also pay attention to the size of the molecules of vitamin C. The molecules should be small enough to increase the penetration and be easily absorbed by the skin, making the whitening effect more obvious.
