Why does the face tend to get oily on rainy days?

Facial oiliness tends to occur more easily on rainy days, generally due to changes in temperature and humidity that make it difficult to maintain the skin's oil-water balance. This condition requires appropriate treatment based on specific causes. Detailed analysis is as follows:

On rainy days, lower temperatures may impair skin blood circulation and slow down skin metabolism, potentially disrupting the skin’s oil-water equilibrium and leading to increased oiliness. At the same time, the high humidity during rainy weather may elevate moisture levels on the skin surface, triggering increased sebum production, which could also contribute to the aforementioned symptoms. For individuals experiencing excessive facial oil, treatment options under a doctor’s guidance may include oral medications such as vitamin B6 tablets or isotretinoin soft capsules. Additionally, chemical peels (such as glycolic acid peels) can accelerate skin metabolism and help remove excess oil from the skin.

Patients with persistently oily skin are advised to seek timely medical evaluation at a hospital to determine the underlying cause and receive proper treatment according to medical advice, thus avoiding potential adverse effects. It is also important to develop healthy lifestyle habits, avoid staying up late, refrain from overusing cosmetics, and maintain proper skin cleansing routines.
