Sunburn
Not only cause skin tanning, dark and dark sunburn, strong sun exposure can also lead to sunburn in just a few days. Called the acute toxic reaction, light on medicine mainly for sunlight for several hours after the exposure area of erythema, bright red color, with mild burning sensation, thermal and tingling, severe cases in addition to the skin irritation, can also be blisters and erosion — that is, the acute toxic reaction to light can make the person within days.
Frostbite
In addition to reflecting sunlight, the cold climate itself will also cause a series of adverse effects on the skin: vasoconstriction, low metabolism, significantly reduced water content, fat content, but also easy to appear rough, desquamation, and even chapped phenomenon. Therefore, we can see that Mr. Peng is not only sunburned by the snow and ice surface, but also his skin is very dry and rough, and some color spots are formed. This is related to the slow metabolism caused by the cold, and the pigment is easy to deposit.
The air pollution
Large particles such as sand grains brought by sandstorms adhere to the skin surface, easily clog pores and cause acne, folliculitis, and other diseases, which need to pay attention to cleaning to avoid. However, urban dust such as PM2.5 is even more difficult to prevent. Due to its small size, it can enter the skin and induce allergic symptoms, and form free radicals, resulting in the accumulation of oxidized proteins, thus leading to premature aging of the skin.
Dry
Dryness is a prerequisite for sensitive skin. It is easy to lose the protection of natural moisturizing factors, the adhesion between cells is lost, the skin barrier function is damaged, the skin is dry, and the allergen is easy to enter the skin on a large scale. At the same time, due to a further decrease in metabolism due to dehydration, pigmentation is also more likely to occur or, once it occurs, less likely to go away. This is also why dry skin is more prone to spots.
The high temperature
Burning hot climate not only makes a person perspire a lot, lose moisture, also can make sebaceous gland secretion exuberant. Too much sebum and metabolites accumulate on the skin surface, and the skin’s own balance of water and oil is destroyed: although there is much oil, there is a serious water shortage. And the destruction of the balance of water and oil is an important cause of acne: strong sebum secretion first and pore thick mutual cause and effect, when the pore can not timely discharge oil, then the formation of horn plug plugging pore, acne.
So please keep protection your skin from now on!
