Why does acne tend to worsen during the rainy season?

Due to increased humidity, sebum production increases, making it easier for sweat and sebum to clog pores. Additionally, this environment is conducive to bacterial growth, which is another cause.

What are the symptoms of mask-related acne?

Mask-related acne is caused by friction, moisture, and bacterial growth from wearing a mask. The environment inside the mask is more humid than the outside air, and acne tends to appear on the chin and cheeks.

What are the differences between chest and back acne and regular acne?

Chest and back acne may need to be differentiated from conditions like folliculitis or Malassezia folliculitis. In some cases, regular acne treatments may not be effective, and if there is no improvement after two weeks, a dermatologist visit is recommended.

What are the key points for skincare during the rainy season?

It is important to maintain hydration while removing excess sebum without over-cleansing.
