How to choose sunscreen in winter

When it comes to sun protection, people will definitely think of the scorching summer days with temperatures above 30 degrees Celsius, and believe that sun protection is only needed then, and the winter sun will not tan people's skin at all. However, skin care experts believe that the effect of ultraviolet rays on pigmentation or freckles is a gradual result that accumulates over time.

Even in the cold winter, we must not ignore the ultraviolet rays in the sun. Of course, there are certain considerations when choosing sunscreen - the higher the SPF value, the better, and a higher SPF does not necessarily mean better sun protection effect. For example, the sun protection effect of SPF30 is not more than twice that of SPF15. However, high-factor sunscreens often contain more sunscreen ingredients, which will inevitably increase the burden on the skin and lead to the formation of blackheads and acne.

Generally speaking, sunscreen products with an SPF value of 15 are more suitable for people to use in winter. Therefore, when you go out, it is best not to be afraid of the trouble and still apply sunscreen carefully. In addition, the effectiveness of sunscreen is relatively short-lived, generally 2 to 3 hours. Therefore, remember to reapply 2 or 3 times regularly to ensure good sun protection effect.

Although sun protection in winter is not as troublesome as in summer, this necessary sun protection step cannot be reduced. There are ways to protect yourself from the sun in winter.

1. We should use whitening sunscreen essence every day, which has the effect of repairing after sun exposure and whitening and hydrating the skin.

2. Proper massage of facial skin every day can promote facial metabolism and blood circulation, and has a whitening effect.

3. Apply sunscreen 20 minutes before going out to allow the skin enough time to absorb the nutrients in the sunscreen to achieve the best sun protection effect.

4. You don’t need to use a parasol when going out in winter, but the editor still recommends that you wear a hat when going out, which can protect you from the sun and keep you warm, killing two birds with one stone.

5. Replenish water for the skin. Replenishing sufficient moisture for the skin can relieve skin damaged by the sun.
