Chapter 4 A woman who pays attention to sun protection will age beautifully

Young women with fair and clear skin.Even under the strong sunlight, the face will only appear smoother and more moist.Until one day, they were horrified to find that the sun-burned skin had quietly appeared small spots.It is imperative to use effective sunscreen as soon as possible to prevent the pigmentation from getting worse.

Ultraviolet rays in sunlight are ubiquitous, and they are still strong even on cloudy days.When ultraviolet rays damage the skin, the body's natural defense system will take corresponding countermeasures, that is, to produce more melanin to protect the skin.Melanin is transported from melanocytes to keratinocytes.

If the sun exposure is only temporary, the melanin will reach the surface of the skin along with the keratinocytes, and the metabolism will expel these melanin-containing keratinocytes, and then restore the original skin color.However, when the metabolism slows down or the skin is continuously exposed to the sun, the stratum corneum of the skin will become thick and rough, and the melanin cannot be excreted from the body, and it will gradually deposit in the dermal tissue, and the skin pigmentation will naturally deepen.

Moreover, the sun's damage to the skin is cumulative. When you are young, it is not a big problem how you bask in the sun. When you are a little older, the spots will quietly appear.At first, the spots caused by sunlight generally appear on the surface of the skin and fade away easily; however, when these superficial spots cannot be eliminated in a short time and form deep spots, it is not easy to remove them.

How to protect the skin well and keep the pigment from pressing on, let's take a look at which skin care products to choose for beauty-loving women.

First, use sunscreen before heading outside.

The sunscreens that women often use include sunscreen, sunscreen lotion, sunscreen oil, etc. Before buying these products, you must first know your skin type, and then use the corresponding sunscreen according to the number.

The easiest way is to use a test paper to press on your nose. If there is shiny oil on the test paper, it means that your skin is oily and you should use lotion; if there is no oil on the test paper, it means that the skin is close to normal or dry skin. , The range of choice is larger, you can choose sunscreen, lotion or oil; if the test paper is a little oily, but not so serious, you can choose cream.

Every time you go out on a sunny day, you should apply sunscreen, and you should wipe it every 2 to 3 hours.You should also wear sunscreen when swimming, and you should also use sunscreen products that are waterproof and have a high SPF.

Second, consider using a "black remover" when you go home.

When many people return from travel, not only their faces, but also their bare arms and calves will be tanned.At this time, you can use 3% to 5% hydroquinone cream on the skin, and the skin can be restored to its original appearance after two weeks of application.However, you should not rely on this chemical drug for a long time. It can only remove the pigment of the epidermis, but it can do nothing for the pigment of the dermis.

The ideal sunscreen product should be a perfect combination of physical sunscreen and chemical sunscreen.This "perfection" refers not only to the perfection of the ratio, but also to the perfection of the ingredients.

Again, we must understand physical sun protection.It refers to the use of opaque particles in sunscreens to directly block, reflect or scatter ultraviolet rays.While it works well, it's too white and sticky when applied to the skin, limiting its usefulness.

Finally, chemical sunscreens are also important.It refers to the effective sunscreen chemical ingredients contained in sunscreen products. After being absorbed by the skin epidermis, it interacts with ultraviolet rays, thereby changing the wavelength of ultraviolet rays and transforming them into harmless energy. Generally, it takes 30 minutes to apply.

Chemical sunscreens need to absorb ultraviolet rays, and can only be effective after being applied for a period of time, and are generally more transparent and refreshing.But some women may be allergic to certain ingredients, because several chemicals in these sunscreens work together to absorb most of the UV rays.

In order to combine the advantages of both, more than 80% of the current products are physical and chemical sunscreens.Products for sensitive skin may be purely physical sunscreens.

In addition, on sunny days, if you like to be outdoors and want to maintain the milky skin that everyone admires, in addition to applying sunscreen and skin care products on your skin, you must also take all-round preventive measures, and the most effective The best anti-spot method is to avoid direct sunlight on the skin.

Fully armed with sunshade and sun protection
When the temperature is higher than 25°C, effective protection from light must be prepared for outdoor activities.Especially from ten o'clock in the morning to two or three o'clock in the afternoon, during this time the sun is strongest and the ultraviolet rays are the most powerful, so try not to go out; if you must go out, you should wear a sunhat, sunglasses or an umbrella, preferably wearing Cotton and linen long-sleeved clothing.

"Duoduo Umbrella" when going out

Under the same conditions, the darker the color of the fabric used to make parasols, the stronger the corresponding anti-ultraviolet performance. Black, navy blue, and dark green have better anti-ultraviolet properties than light blue, light pink, and light yellow. it is good.At the same time, parasols made of silver tape and pearl tape have better sun protection effect, and the denser and thicker the texture, the better the sun protection effect.

The "cap" is not surprising, both front and back
Wearing a four-inch wide-brimmed round hat can not only cover the face, but also protect the skin of the ears and the back of the neck. Good air permeability can prolong the wearing time.Although the style of the peaked cap is more fashionable, the sun protection effect is not comprehensive enough.

Loyally guard the universe in the "mirror"
When going out, you should wear sunglasses with large mirrors that cover the skin around your eyes.For sunglasses, the UV index (used to measure the effect of filtering ultraviolet rays) is a very important standard. At present, the UV index of most sunglasses is 96% to 98%. Dark lenses are better than light lenses, especially for sports. Excellent.

Choose your attire carefully

Pure cotton fabric has the characteristics of good sweat absorption, strong air permeability and comfortable wearing. It is the preferred fabric for most UV protection clothing.When the sun is strong, it is best to wear dark clothes, such as scarlet, dark purple, and indigo cotton clothes.For bare arm skin, you can wear a light gauze shawl or sleeves to protect from the sun.

Beauty Tips:
In addition to the face, the hands are most vulnerable to ultraviolet rays, and the back of the neck, shoulders and instep are also vulnerable to direct ultraviolet rays. Delicate lips should also be coated with lipstick and lip gloss with sunscreen .
