First, we must go over how a hair follicle develops in an embryo. Before the eightieth gestational day, the embryo has no hair, not even any cell colonies that are destined to turn into a hair follicle. After the initial skin like layer, the periderm, sheds off, epidermis and dermis develop, but without any sweat glands, or hair follicles within the dermis. Around day eighty, colonies of epidermal cell bud into the dermis. Further growth of these buds makes up hair follicles and sweat gland ducts. Indeed, we could regard hair follicles and sweat glands as sink-holes on the surface of the skin, what is referred to as the invaginations of the epidermis. Later, sebaceous glands, which are oil producing organs bud off of the upper part of the hair follicles. .

When the hair follicle and its appendage, the sebaceous gland duct, become blocked, and as a result become so inflamed that a tiny abscess forms, the compounds that are involved in abscess formation could damage the apparatus of the oil gland duct and the hair follicle that it is attached to. A dilated pore is, in essence, a scarred hair follicle-oil gland structure.

How Can a Dilated Pore Be Treated?

Fortunately, the dilated pore is small enough that after numbing the skin it can be cut out by using a small cylindrical blade, and sutured in a manner that would leave minimal to no scar.
