Should I use sunscreen in winter?

You need to use sunscreen in winter, but sunscreen is needed all year round. Moreover, in some places, ultraviolet rays in winter are stronger than in summer, and the skin is more vulnerable to damage.

Professionally speaking, winter and spring are the seasons with the lowest global ozone content in the year. Without the ozone layer as a "protective coat", more than 95% of the sunlight's UVA (long-wave ultraviolet rays) will penetrate the clouds unscrupulously, regardless of whether it is sunny or cloudy, and even enter indoors, directly penetrating into the dermis of the skin, destroying collagen and elastic fibers, causing the skin to age and loosen prematurely, and causing wrinkles and pigmentation.

Moreover, the air is relatively dry in winter, which slows down the skin's circulation and metabolism, and weakens the skin's self-renewal and repair functions. Under long-term exposure to ultraviolet rays, the skin is more likely to darken and deteriorate.

Therefore, it is even more necessary to use sunscreen in winter.

How to choose sunscreen in winter

Generally, when we buy sunscreen, there is a value for it. For example, in summer we will choose sunscreen with SPF15 or above, while in winter, the choice is generally around SPF8-15 depending on the region.

In addition to sun protection, winter sunscreens also need to replenish moisture, which means that the sunscreen you buy can also replenish moisture, moisturize, and deeply moisturize.

Moreover, most summer sunscreens are waterproof, because it is easy to sweat in the summer and people are afraid that their makeup will be ruined, so they buy waterproof ones. But it is different in winter. In winter, the skin is drier and lacks moisture, so moisturizing sunscreen is needed to moisturize the skin.
