Ultraviolet light is one of the culprits of aging. Sun protection is not only to prevent tanning, but also to cause skin spots and wrinkles, destroy collagen, and make skin lose elasticity and relaxation. Therefore, no matter what type of skin care products are used, whether it is sunny or rainy, sun protection must be essential. Of course, when it comes to using VC skin care products, because the composition of VC is unstable, the effect will be weakened under ultraviolet radiation. For things bought with real money, which are time-consuming and laborious to apply, they can exert their effects for a long time and also need sun protection. It is recommended to go out and apply sun protection.
