The Vietnamese word "mụn" generally refers to a type of skin blemish, commonly known as "acne," "pimple," or "blackhead." It is used to describe various skin eruptions that can appear on the face or other parts of the body.
Acne/Pimple: "Mụn" is commonly used to describe small, raised bumps on the skin that can be red or inflamed. These are often associated with teenage years but can occur at any age due to various reasons, including hormones and skin care habits.
Blackhead: It can also refer to a blackhead, which is a type of acne that appears as small, dark spots on the skin, commonly found on the face, especially on the nose.
