Acne will appear if the climate is too humid or too dry. How to take care of your skin? Let’s take a look at today’s weather first!

Does acne often make you feel upset? In fact, the high temperature and humidity in the subtropical environment are indeed environments that can easily exploit acne. Therefore, the next time you have an acne breakout, in addition to paying attention to your own internal factors, you can also prescribe appropriate medicine based on the weather.

Liu Kangling, a dermatologist at the Renai Campus of Taipei City United Hospital, said that there are three main internal causes of acne: Excessive secretion of sebaceous glands, leading to blocked pores Excess male hormones Bacterial infection (common ones include: acne Propionibacterium)

In addition to internal factors, external weather factors can also affect skin health. Liu Kangling analyzed the causes of acne in high temperature, humidity, haze and dry environments, and proposed corresponding countermeasures. Hot weather

High temperatures have been common in recent days, and you are already sweating profusely after just a few steps outside. Liu Kangling said that sweat carries dirt, which may breed bacteria and cause acne under high temperatures. Therefore, in summer, many people's acne problem will even spread from the face to the back. "If you already know that you will sweat a lot, you may wish to bring a change of clean clothes to prevent sweat from staying on your body and reduce the chance of acne," Liu Kangling suggested. Humid Weather

Taiwan is surrounded by the sea, and there is almost no day that is not humid. Especially when the southerly wind blows in the summer, the dehumidifier at home has no chance to rest. An environment with excessive humidity and stuffy heat will cause people to sweat endlessly, and the secretion of sebaceous glands will be strong, which will lead to acne easily.

Liu Kangling suggested that if you want to avoid acne caused by humidity and heat, the most important thing is to stay dry; "In addition, when you have acne, try not to wear makeup, especially for women. Concealer products will clog pores, and long-term use will only lead to a vicious cycle. "In addition to not wearing makeup temporarily, washing your face moderately and keeping your skin dry can help heal acne faster." Smog days

As the problems of smog and PM2.5 become more and more serious, many people have discovered that the number of acne on their faces is actually directly proportional to the number of smog days. Don’t underestimate these invisible tiny particles floating in the air. Their damage to the skin is not limited to acne.

Air pollutants have harmful effects on the skin by increasing oxidative stress, causing changes in the normal functions of lipids, deoxyribonucleic acid and proteins in the skin. Liu Kangling explained. Even on hazy days, the most important thing is to wash your face the right way and strengthen moisturizing and sun protection.

Since humid climates are prone to acne, many people think that dry environments are more susceptible to acne. Good for skin health. Liu Kangling said that current studies have pointed out that compared with ordinary skin, the concentration of ceramide in acne-prone skin is significantly reduced in a dry and cold environment, which damages the skin barrier function and increases epidermal water loss. In addition, Liu Kangling reminded that because the weather is dry, the skin is not as shiny as when it is hot and humid. Some people will think that the skin is clean and neglect to clean it, allowing dirt to accumulate on the face. "So, in a dry environment, in addition to paying attention to moisturizing to keep the skin stable, you also can't be lazy in cleaning," Liu Kangling said.
