Children have small rice bumps on their faces.

This symptom can be seen in milia, which is a beige or white particle that occurs on the skin of the face. It usually occurs in women. It is caused by a small white cyst formed during the skin's self-healing process due to a small cut in the skin. It may also be due to sebum being covered with keratin and not being able to drain normally to the epidermis, so it accumulates in the skin to form white particles. Its lesions appear as beige or white pin-sized pimples on the skin of the face. Milia is caused by hyperkeratosis of the skin at the opening of sweat glands. Some scholars believe it is related to endocrine factors. It can be treated with laser or electrocautery. In addition, it is necessary to distinguish acne in children and facial pimples caused by atopic dermatitis.
