Don't say you don't know what sunscreen index is suitable for use in winter

We all know that ultraviolet rays are strong in the summer and we will get tanned if we are not careful, so applying sunscreen is the most important step in skin care. So, do you need to apply sunscreen in winter when ultraviolet rays are weaker? What sunscreen index is suitable for winter?

What sunscreen index is suitable for winter

SPF between 15 and 25. The appropriate sun protection factor is between SPF15 and SPF30. Products with SPF15 can block 93.3% of UVB, and products with SPF30 can block 96.6% of UVB. In winter, the skin produces less oil, and high-factor sunscreen will put pressure on the skin, so you only need to use a sunscreen product with a slightly lower factor.

Should I use sunscreen in winter?

Whether it is sunny or rainy, you should use sunscreen all year round. Although ultraviolet rays are stronger in summer, there are also ultraviolet rays in winter. If you don’t protect your skin from the sun, your skin will easily be affected by ultraviolet rays and gradually darken. Then the fair skin that you have maintained for the whole summer will be defeated in winter. So if you want to keep your skin fair all the time, you must pay attention to sun protection in winter. Moreover, in winter, the ozone layer content will decrease, and the ultraviolet rays will be stronger than in summer, causing greater damage to the skin. If you do not use sunscreen, your skin will be more prone to aging.

When the weather turns cooler and winter comes, the skin's circulation and metabolism will become slow, thereby weakening the skin's self-renewal and repair functions. If you don't do a good job of sun protection in winter, your skin will be affected by ultraviolet rays and produce melanin, which will be difficult to excrete and eventually form spots. Sunscreens in winter generally have stronger repairing abilities, so if you insist on applying sunscreen in winter, it can help strengthen the elasticity and toughness of skin fiber cells, strengthen and repair skin tissue, and improve dry skin.

Should I wear sunscreen if I don't go out in winter?

Many people think that as long as they don’t go out, they don’t need to apply sunscreen, but this cannot completely block out ultraviolet rays, not to mention the radiation from computers, televisions, etc. In addition to the fact that we know that we must insist on applying sunscreen products indoors and on cloudy days, there are several places that are easily overlooked. One is the snow, where the refractive index of ultraviolet rays can be 80-90%; the second is some KTVs and entertainment venues, where the ultraviolet lights are like the ultraviolet rays in the sun and can cause great harm, so when applying sun protection, don't forget these blind spots.

Choosing sunscreen in winter

1. Winter sunscreen should be moisturizing

When choosing sunscreen in winter, it is best to use a moisturizing sunscreen because the climate is relatively dry in winter. Dry skin will accelerate skin aging, so it is best to use a sunscreen product that has both sun protection and moisturizing effects.

2. Winter sunscreen does not need a high SPF

Although the intensity of ultraviolet rays will increase in winter, you don't need to choose sunscreen products with too high an SPF. An SPF between 15 and 25 is enough, because doubling the SPF does not mean doubling the sun protection strength, it will just put a greater burden on the skin.
