What is bier spots?

Bier spots, also known as café-au-lait spots, are light brown skin pigmentation with uniform pigmentation that appears at birth or in early childhood. These spots are usually benign and do not cause any health problems. They are typically smooth and flat, and can vary in size and shape.

Bier spots are caused by an increased amount of melanin, the pigment that gives skin its color, in the affected area. They are usually found on the trunk, buttocks, and thighs, but can also occur on other parts of the body.

Most bier spots do not require treatment, but individuals with numerous spots or larger spots may choose to have them evaluated by a dermatologist for cosmetic reasons. In rare cases, bier spots may be associated with certain genetic conditions or syndromes, so it is important to consult a healthcare professional if you have concerns about these spots.
