Of course it is necessary. Although the weather is cold in winter, ultraviolet rays still exist.
We use sunscreen to protect not only from sunlight, but most importantly from ultraviolet rays.
When ultraviolet rays are directly irradiated on the skin, they will penetrate the skin layer and directly damage the skin base, accelerate skin aging and relaxation, and cause melanin accumulation and precipitation, making it darker, and even causing spots and skin damage.
Not only in winter, even in rainy weather without sunlight, ultraviolet rays can still penetrate the clouds.
【Sun protection method】
1：Applying sunscreen products: refers to the use of sunscreen, spray and other products. Apply directly on the skin to provide the most appropriate protection for the skin.
2：Use something that can block ultraviolet rays, such as a hat or umbrella, to block direct sunlight.
