What are the harms of sunscreenWant to know how sunscreen is good for your skin

The harm of sunscreen is mainly because the ingredients of some sunscreens are more complex, for example, some chemical sunscreens will add benzophenone as an auxiliary sunscreen in order to resist UVA, and benzophenone is an allergenic ingredient, which will affect the human endocrine, and will affect the health of marine organisms, such as destroying coral DNA, endangering the health of dolphins, etc., in addition, there are OMC, benzoates and other ingredients are also listed as harmful substances, allergenic ingredients, which will affect human endocrine.

Chemical sunscreen ingredients are more complex, and relatively speaking, physical sunscreens that rely mainly on titanium dioxide and zinc oxide sunscreen are safer, but they may be heavier and tend to clog pores.

However, compared to the damage of ultraviolet rays to the skin, the harm of sunscreen is minimal, so it is still recommended to use sunscreen, choose a physical sunscreen with safer ingredients, and pay attention to cleanliness.

Unsafe ingredients can be detrimental.

Safe no.

Be sure to apply it every day to delay aging. The next day, I swiped another blogger who said that sunscreen can't be worn every day, because the essence of sunscreen is actually cosmetics. If you use it for a long time, it will clog your pores, and once you don't wear makeup, your face will look sallow and sallow, which is particularly ugly and has no complexion.

So what exactly is it? Let's have a ** after all.

Sunscreen is an ingredient that absorbs ultraviolet rays.

sunscreen, thus achieving protection against skin darkening and sunburn.

A kind of cosmetic product. According to the principle of sun protection, sunscreens can be divided into chemical sunscreens and physical sunscreens. Consumers can also be based on different SP F and PH values.

to choose different products that suit you.

If you wear sunscreen every day, it will definitely hurt you. Because after all, he belongs to the category of cosmetics, which contain chemical ingredients. If you don't remove makeup and cleanse properly, it's likely to clog your pores.

If you choose a chemical sunscreen, then the cleansing must be done properly and the makeup must be removed carefully. If you have sensitive skin and want to protect yourself from the sun but are afraid of allergies, you can choose a physical sunscreen. Physical sunscreens are safer, gentler, and a boon for sensitive skin.

So don't be afraid that a touch of sunscreen is very harmful to **, as long as you choose a sunscreen with high mildness, strong safety, and a good sense of use, you can use it with confidence.

Note that it's important to emphasize here that you can protect yourself from the sun every day, but you don't need to wear sunscreen every day. If you're in the heat of summer or need to go outside, apply sunscreen appropriately. But if you're not going out or working indoors, or on a cloudy, rainy day, you can replace it with quarantine.

Because most of the isolation now contains a certain sun protection factor.

It is enough indoors.

It won't hurt, and using sunscreen every day can make ours** slow down aging. Without sunscreen, ultraviolet rays can easily invade our skin and cause certain damage to the skin, resulting in sunburn and tanning, and sunscreen can just resist this damage.

Sunscreen is used all year round, because ultraviolet rays are present all the time, sunscreen is to protect our skin from ultraviolet rays, people who use sunscreen will look 3 to 5 years younger than their peers, it is because sunscreen reduces the impact of photoaging on our skin.

The correct way to use sunscreen is to do a good skin care foundation before applying it, and only use sunscreen after using the lotion. Generally, after applying sunscreen, we have to wait for 15 to 30 minutes before going out, this time is to let the sunscreen form a protective film on the surface of our skin, and it will not have a sunscreen effect if you go out directly after applying.

The use of sunscreen should be chosen according to the skin type. Sensitive skin and acne skin should look at the SPF value of sunscreen when choosing sunscreen, the larger this number means that it has a stronger sunscreen effect, and the heavier the sense of use, acne skin and sensitive skin are not suitable for using this sunscreen.

People who often work outdoors can use sunscreens with SPF values greater than 50 in the summer, and reduce it to 30 in the winter.

Sunscreen contains chemical ingredients, especially some sunscreens with waterproof and sweatproof effects, because they isolate the contact between the outside air and the skin, the skin is easy to breathe, which causes these chemical ingredients to clog our pores, even if there is no makeup on the day, only sunscreen, you must remove makeup and clean before going to bed.

Causes dryness, allergies, etc. Dry, sunscreen contains substances that can make ** dry and dehydrated; Allergies, regular application will make ** thinner and allergic.

Wearing sunscreen often can play a role in protecting, and it can also make you very delicate and white, and there will be no spots, but sunscreen also has some chemicals, so you have to remove makeup every night, if you can't remove it cleanly, it will become very rough, the pores are also very large, and there will be some acne.

Wearing sunscreen every day may cause you to become very sensitive, and it will also weaken your barrier, and it may also cause you to be very intolerant, and it will also lead to poor resistance, which will lead to allergies and redness.

The harm of wearing sunscreen every day is that 1 will be stuffy acne, 2 will produce ulcers, 3 will be red and swollen, 4** will be very itchy, and 5 will be powdered, so don't apply it every day.

Wearing sunscreen every day will make ** very rough, and the pores will be very large, sunscreen is also a chemical, if it is not cleaned, ** will also have some acne and spots, so when choosing sunscreen, you should choose some pure natural sunscreen.

Wearing sunscreen every day is not harmful, but if you don't wear sunscreen, it will be very harmful.

If I spend the whole day indoors, do I need sun protection? In principle, it is needed.

It starts with ultraviolet light. Because no matter sunny or rainy days, ultraviolet rays exist, and ultraviolet rays are divided into different bands, and the main ones that affect the human body are UVB and UVA.

UVB is ultraviolet rays, which can reach the basal layer, causing sunburn and redness, but it has medium penetrating power and can be blocked by clouds, glass, parasols, clothes, etc., and is most intense in summer and noon.

The UVA is a kind of ultraviolet rays with the longest wavelength, the strongest penetration, which can penetrate the dermis through the window glass and clouds, so that the sunburn cavity is black, the water-holding capacity decreases, the surface becomes dry, and at the same time accelerates oxidation and aging, and all kinds of dry lines appear erect, and even cancer.

When we stay indoors, basically all UVB can be blocked by the window, but some UVAs will enter the room through the window glass (American Cancer Society data), even the dark glass can only block the UVA

If you have a special UV protection film attached to your home or car window, you can block UV rays.

If there is no protection, sun protection is still recommended. Because the damage of ultraviolet rays is accumulated over time, there is no damage now, but as you get older, where you get sunburned frequently, you will slowly appear spots and wrinkles.

Also, about whether sun protection is counterproductive to skin care.

Some of the chemicals in sunscreen may penetrate the sunscreen. But yours are not sensitive, not in the inflammatory phase, no bevel, and it is very difficult for most sunscreens (all physical sunscreens and most chemical sunscreens) to penetrate into.

The only thing to note is a sunscreen called "benzophenone-3", which is known to have good sun protection but slightly less safety, and it has a relatively strong permeability.

How to avoid it? Don't buy American-style sunscreen. (The U.S. FDA is right about a lot of things, but it is not known why it is so slow to approve sunscreens that manufacturers in the U.S. have to use benzophenone-3 for formulations because the new sunscreens are not legal in the U.S.).

Most other countries (Europe, Japan, Australia) have approved sunscreens that can replace benzophenone-3, so they don't use this penetrating ingredient. So what we have to do is avoid sunscreens that are safety hazards, not sunscreens.

If you are in a sensitive period, it is best to take hard sun protection (umbrellas, hats, glasses, masks, etc.) to avoid UV damage.
