We all know that the sun is light in autumn and winter, and even sometimes there is no sun exposure, so do we still need to apply sunscreen at this time? In fact, it is not appropriate to judge whether sunscreen is needed by the intensity of the sun.
The purpose of our sun protection is not to protect against visible sunlight. Some girls do not do facial sunscreen at all in the autumn and winter, and after a whole winter, they will find that the difference between facial skin color and neck skin color is obvious, and their faces are tanned. Do you need sun protection in autumn and winter? What are the characteristics of autumn and winter sunscreen? Today we will talk about this topic in detail.
What is sun protection?
Since sun protection is not a defense against light visible to the naked eye, what do you need to protect against? In fact, the sunscreen skin care behavior we take is to defend against ultraviolet rays, and ultraviolet light is invisible to the naked eye.
The ultraviolet light that can affect the human skin is UVA and UVB. They not only cause the skin to darken, but in the case of prolonged contact with the skin, it is easy to cause skin photoaging problems. In simple terms, it will cause the facial skin to appear fine lines prematurely, grow sun spots, dull skin tone for a long time, and may also cause sensitive skin manifestations, which can seriously cause other skin conditions.
So are UVA and UVSB in a state that remain in one state all year round? Of course not. In general, the ultraviolet intensity in autumn and winter will be significantly weaker than in spring and summer. However, there are also special circumstances, such as high-altitude snowy mountain areas, or large-scale snow environments, and the intensity of ultraviolet rays can even be comparable to spring and summer.
So in our daily lives, how should we judge ourselves and whether we need to take sun protection measures? If you need to go out, we can choose the sun protection method through the UV ultraviolet prompt in the weather software. If the index value is below 3, there is no need for additional sun protection; when the index value is greater than or equal to 3, it is necessary to carry out separate sun protection.
For general commuting, or ordinary outdoor activities, applying spf30, pa++ sunscreen is enough. If you need to be exposed to the outdoors for a long time, in the case of play, you can choose a higher multiplier sunscreen. There is one thing to confirm when choosing a sunscreen, not that the higher the index, the better. The higher the sunscreen index, to some extent means that the sunscreen irritation increases, which is actually very "fatal" for fragile skin.
In addition, I don't need to go out, I often stay indoors, do I need extra sun protection? In principle, people who spend a lot of time indoors do not need to apply sunscreen. But people who are close to the window and often face computer equipment need to take sun protection measures. People within 1.5 meters of the window can choose to close the curtains or apply sunscreen. The principle of indoor sun protection is to avoid as much as possible and avoid skin contact with ultraviolet rays. If you can't avoid it, apply sunscreen again.
What is effective sun protection?
In fact, the daily use of sunscreen measures should be based on avoiding obstacles, which is really not enough, and it is necessary to apply sunscreen. For sunscreen ingredients, chemical sunscreens may have the risk of irritating the skin, and physical sunscreens require additional makeup removal and cleaning, both of which have weaknesses. However, some of the materialized sunscreens on the market can eliminate the need to remove makeup and clean, reducing a certain sense of irritation.
In addition, apply sunscreen in autumn and winter, and in the absence of special requirements, try not to use products with waterproof and sweatproof effects. On the one hand, this type of sunscreen is mostly refreshing to use, and some products may contain alcohol, which is more likely to cause irritation for autumn and winter skin with weak barrier defense. On the other hand, this type of product requires additional makeup removal, which is not friendly to autumn and winter skin with a light sebaceous membrane. So apply sunscreen, we can choose basic sunscreen, do not have to pursue too strong efficacy.
In addition, in the cloudy state, cloudy weather out, you also need to pay attention to the ultraviolet index, moderate sun protection. As mentioned earlier, ultraviolet light is not visible, and no sunlight does not mean that there is no ultraviolet light. However, in the autumn and winter rainy weather, the general ultraviolet index is weak, at this time the umbrella can resist ultraviolet rays, and no special measures are required.
Regarding the question of whether makeup needs to be removed after applying sunscreen, pure chemical sunscreen and functional sunscreen all need to be removed separately. Just wash with facial cleanser is not clean, sunscreen residue will clog the skin pores, causing skin stuffiness and other situations. The cleanser washes the sunscreen and does not need to remove makeup again. Be careful though, you must wash your face with a cleanser! It is not possible to rinse with only clean water.
Autumn and winter seem to be weakening the light, but in fact, they are still "in danger". Dear friends, or don't take it lightly, the protection that should be done must not be saved!
