【Laiwo Medical: Knowledge Sharing】Which faction does your seasonal acne belong to, Northern Dry Acne vs Southern Oil Acne?

Publish Date: 2025/9/18


       I have only recently truly felt that autumn has truly arrived. The temperature difference between morning and evening in the north is widening, so you have to wear a coat when going out; The south is finally gradually shedding the heat, and the evening breeze is beginning to bring a hint of comfort. Just as everyone was exclaiming 'the weather is finally comfortable', when they looked in the mirror, they suddenly realized that acne had started to grow on their faces again!



       So I quickly started a self reflection mode: "Have you been eating too much hotpot lately?" "Did last week's milk tea exceed the sugar limit?" "Or is it the retribution for staying up late watching TV shows?"... Wait a minute, this time it's not necessarily all your fault. Suddenly getting pimples during a seasonal change may not be due to something wrong, but rather because your skin is going through a period of adaptation to the changing season.

Northern faction 'dry acne': a danger signal in the desert

       The biggest feature is the external dryness and internal oil. Autumn in the north is like a huge dehumidifier, with strong winds instantly removing moisture from the surface of the skin. At this point, the skin barrier panicked, triggering the self-protection mechanism and starting to produce oil crazily. The sebaceous glands began to work overtime, causing the skin to peel and acne at the same time.



Southern style 'oil acne': a feast of bacteria in sauna rooms

       'Damp heat blockage' is the main culprit. The autumn tiger in the south continues to dominate, the air is humid and hot, and the pores seem to be in a sauna. Under the dual stimulation of high temperature and high humidity, sebaceous glands become abnormally active, secreting a large amount of oil that mixes with sweat and cosmetics residue, causing the stratum corneum to absorb water and expand, forcing pore openings to narrow or even completely block. In this way, the closed mouth, pimples, and red and swollen pimples quietly appeared unconsciously.



       However, there is no need to panic when dealing with acne in autumn. We can take targeted care according to the different autumn environments in the north and south: Northern students may consider placing a humidifier indoors to maintain a suitable humidity in the air and create a relatively comfortable environment for the skin. They should also drink plenty of warm water to replenish moisture from the inside of the body and relieve discomfort caused by dryness. In addition, when washing their face, they should avoid using overheated water, otherwise it will take away more natural oils from the surface of the skin, making the skin barrier more fragile; Although students from the southern school have shed the high temperature, they still occasionally feel stuffy and hot during the day, making them prone to sweating. At this time, it is important to wipe them off in a timely manner to keep the skin surface dry and avoid sweat clogging pores. At the same time, it is also necessary to regularly change pillowcases and bed sheets to reduce the possibility of bacterial growth.



       At the end of the day, getting acne during seasonal changes is like a "little cold" for the skin. We don't need to be overly anxious, give it some time, patience, and the most suitable care, and slowly we can regain a stable state. Finally, Laiwo Medical kindly reminds that sensitive skin during seasonal changes is a common problem. Scientific care and a relaxed mindset are the key to a smooth transition.
