The second step is to make a mask and repair the cooling and hydrating type.

Step 3: Apply toner and skin cream.

Eat more fruits at ordinary times. Drinking more water is also good for your skin.

I think swimming will make the skin worse.

1 Due to the influence of various germs in the swimming pool, the disinfectant may not 100% sterilize. Doctors say that there are many diseases that can be spread by swimming, such as beriberi. In some swimming pools, the circulation system is not always on, so it is inevitable that bacteria will grow. Some man-made unsanitary factors can also pollute the pool water, such as skin excrement, sweat, runny nose and even urine, which are inevitably brought into the water and become allergens of the skin. People with allergies should be more careful.

2. The influence of disinfectants in swimming pools. The water in swimming pools is generally disinfected with chlorine solution. The hypochlorous acid contained in disinfectant is the same as washing powder, and the general disinfectant will affect the swimmer's hair. Due to the problem of allergic constitution, some people will have skin allergic reactions after encountering disinfectant, such as long red spots.

Ultraviolet rays are not only directly projected on the skin and hair, but also hurt the skin and hair through the reflection of water when you swim outdoors. Long-term exposure can cause sunburn or acute dermatitis, also known as sunburn; It will also destroy the DNA in skin cells, make skin cells mutate and grow out of control, leading to skin cancer. In this case, the skin will be more seriously damaged than on land because of the high reflection of water on ultraviolet rays, and it is easy to dry and wrinkle because of the loss of water, which can also explain why many people find dandruff and fine lines on their skin after soaking in water for so long.

There are also some special bathing products for swimming in the market. These products are said to be able to sterilize skin care, chlorine and bleaching powder, which is very suitable for people who often swim in the water.

Skin care during swimming mainly focuses on three aspects: sun protection, cleaning and moisturizing.

★ Sunscreen It is reported that the skin in water will double its absorption of ultraviolet rays due to the reflection of the water surface. Therefore, the choice of sunscreen products requires not only SPF30 or above, but also PA sunscreen products, and it is best to choose sunscreen emulsion with waterproof function. Sunscreen should be applied half an hour before swimming, so that it can be completely absorbed by the skin. It will only be effective if it is applied to a certain thickness, and it should be applied to the whole body. Make it up every two hours and once after swimming ashore.

However, even if you have done all the sun protection work, experts still suggest that you try to avoid swimming in the sun from 1 1 to 4 pm, because the ultraviolet rays during this time are too strong and do great harm to the skin.

★ clean

In addition to sun protection, skin cleaning after swimming is equally important. According to experts, the water in swimming pools is high in ammonia, hydrogen and urea due to continuous use. Swimming pools often use chlorination or circulating purification to keep the pool water clean, which will increase the concentration of chlorine. In addition, some skin excretions, shed hair, swimsuit dyes, fibers and even urine will also be brought into the water when swimming. Such water often causes diseases such as skin, so you must thoroughly clean your skin after swimming, and you can use a bath like "swimming dew" to clean it. This product can help remove fungi and bacteria, has skin care function, and can remove chlorine odor and bleaching powder from the body after swimming, making the skin clean, smooth and moist.

★ Moisturize

Many people have this experience: after swimming, they don't dry the water immediately, and the skin becomes very dry after the water dries naturally? This is because if the humidity in the air is not high, as the wet body gradually dries, the water on the skin surface will easily evaporate, thus making the skin drier. Therefore, the best nursing method is to come out of the water, take a shower and dry the water drops on your body immediately.

After soaking in seawater for more than two hours, you will obviously feel that your skin is short of water and oil, so you should apply moisturizing body care lotion as soon as possible after bathing to replenish water and keep your skin moist.

In addition, if the skin has been slightly sunburned, you can apply moisturizing night cream or skin cream to the pain area; If it is serious sunburn and blisters, it is best to seek medical treatment to avoid other skin infections. For women, it is best not to put on makeup immediately, because at this time, the skin will be more or less inflamed, and cosmetics will make it more irritating. In addition, if the surface skin begins to fall off, don't tear off the skin slowly because of itching, but let the dead skin fall off naturally. Because it is not only unsanitary to tear off dead skin by hand, what is more serious is that it will expose immature delicate skin to air and sunshine prematurely, and make new skin form black spots. I think swimming will make the skin worse.
