1, what is PM2.5?
It is a tiny suspended particle in the air with a diameter of only 2.5 microns. Because its diameter is even smaller than 1/20 of the hair diameter, it will not only adhere to the skin surface, block pores and damage the skin, but also be inhaled into the lungs, which will have a very serious impact on human health and environmental quality.
2. Damage to skin
Sensitivity: Long-term exposure to air pollution will destroy the skin protection barrier, and the skin will become more and more sensitive, prone to redness, swelling and itching.
Acne, acne: Dirty and tiny suspended particles in the air penetrate into pores, leading to pore blockage, which is prone to acne and acne.
Spots: Air pollution will stimulate the growth of melanocytes and increase the pigment spots on the face.
Accelerated aging: Without sun protection measures, there will be a crisis of photoaging under the irradiation of strong sunlight and ultraviolet rays. In addition, fine suspended particles in air pollution and exhaust gas from cars and factories all contain a lot of "free radicals", which will also accelerate skin aging.
Wrinkles: The formation of wrinkles is the most important clinical feature of photoaging skin. Long-term exposure to sunlight and ultraviolet radiation will make the arrangement of collagen fibers disorder, reduce skin elasticity and increase wrinkles.
Abnormal keratin metabolism: the normal keratin metabolism is about 28 days. Long-term exposure to environmental pollution will prolong the metabolism cycle of keratin to 40~50 days.
3. Ways to reduce injuries
Sunlight resistance
Wear everything! Wearing sunscreen helps to block ultraviolet rays, and it can also prevent ultraviolet rays from making the melanin contained in the skin more serious. It is recommended to choose sunscreen products such as sunscreen lotion and sunscreen spray with SPF above 25 Pa++. Before using sunscreen products, you can apply a day cream that can resist the stimulation of external pollution, strengthen the stratum corneum and enhance skin defense. In addition, you can add a long-sleeved thin coat, a full-face helmet and a mask with anti-ultraviolet effect, which can block the dirty air and achieve the effect of sun protection.
clean
Going out all day, dirt accumulates on the skin surface and pores all day, so the cleaning work must ensure effective prevention of acne and acne.
"teacher! Do you have to remove makeup without makeup? "
This is the most frequently asked question by fans. Actually, it depends on personal habits. If you don't wear makeup, you really don't need to remove makeup. However, the current sunscreen isolation products usually need makeup removal to be completely removed, so it is recommended to remove makeup and wash your face. Just remind everyone that it is advisable to clean thoroughly rather than excessively, so as not to wash off sebum on the skin and dehydrate the skin.
Regular exfoliation and rejuvenation
In addition to daily basic maintenance, it is recommended to regularly use exfoliating, mud film or products containing acidic substances such as salicylic acid, fruit acid and almond acid according to personal skin condition to help keratin metabolism and clean deep pores.
Compared with ordinary commuters, motorcyclists really need to spend more time and thought to maintain and take care of their skin to keep them healthy. I often say: "Skin has feelings and memories. How you treat her will give it back to you." Don't be impatient, step by step, the skin will give you good results!
4, the magical use of moisturizing lotion
Magic one: mixed makeup (BB cream, liquid foundation, etc. )
Mixed use of emulsion and base makeup (BB cream, liquid foundation, etc.). ) can play a role in moisturizing. It should be noted that when mixing, the addition ratio of emulsion should not exceed the base makeup. After all, the makeup emphasizes the concealer effect. If it is larger than the base makeup, the concealer effect of the base makeup may be weakened. It is better to use lotion directly before applying makeup, which can keep skin moist and lock water. The addition amount of emulsion is suggested to be adjusted according to dry skin or climate; Basically, you can use a rich emulsion and mix it evenly according to the ratio of emulsion 1 base makeup 3, then gently press it on your face and push it away evenly.
Magic 2: Apply lotion to other parts of the body as body lotion.
You can rub facial cleanser on other parts of your body. However, facial skin is more fragile and delicate than body skin, and body skin usually needs more lipids than face, so the moisturizing degree of facial cleanser is not enough for the body. At the same time, the body needs to be widely used. If it is not an emulsion product that is about to expire, it is not recommended to wipe the body, otherwise it will be a waste. However, it is suggested that facial lotion can be used in delicate skin, less oil secretion, or obvious greasy feeling after rubbing, such as neck, back of hand, interphalangeal joints, knees, inner skin of limbs and so on.
Trick 3: Remove mascara, eyeliner and makeup from your face with lotion.
If you don't have makeup remover on hand, you can dip a cotton swab in makeup water to remove mascara and eyeliner, and apply makeup water with a cotton pad to remove makeup on your face. However, although using emulsion to remove makeup is mild to the skin, the composition, proportion and texture of each brand's emulsion are different, and the effect of removing makeup will be different. The degree of emulsification will definitely not be better than that of cleansing oil, and direct use of oil to remove makeup may not guarantee complete removal. It is best to use products specially disassembled.
Coup 4: Coup of "waste utilization" of expired emulsion
1, expired lotion can be used for body care, such as heel or elbow with thick cutin, to keep skin soft.
2. If the nails are dull and rough, you can try to soak the emulsion with a cotton pad, then cover it on the nails, and take it off after 10- 15 minutes, which can achieve the effect of nourishing the nails.
3. You can also use expired lotion as conditioner. After washing your hair, apply hair ends that are easy to split or hair roots that are easy to be short-tempered, so that the hair ends are soft and not short-tempered.
4. You can also pour it on a towel to wipe leather products and shoes, which can slightly clean stains and keep leather soft. Note that expired emulsion does have many wonderful uses, but if it expires for too long or even deteriorates, it is best to throw it away directly.
