Аcne

<h2>Characteristics of rashes</h2>

All morphological elements of acne are divided into three types:

<ul>
	<li>non-inflammatory (open and closed comedones, milia);</li>
	<li>inflammatory (follicular papules, pustules, nodules);</li>
	<li>post-inflammatory (cysts, scars, spots).</li>
</ul>

Comedones are formed as a result of the expansion of the ducts of the sebaceous glands and/or the follicular channel with an excess of sebum below the point where it is difficult to get to the surface.

Milia (white pimples) are single or multiple small whitish, milky-white or whitish-yellow hemispherical nodules the size of a pinhead or millet grain. They arise as a result of accumulation of sebaceous secretion in the mouths of follicles or ducts of sebaceous glands and practically do not differ from closed comedones.

A papule is a small cone-shaped nodule of pink or bright red color, 1-3 mm in size without clear boundaries, slightly rising above the skin level, with an inflammatory infiltrate at the base.

Pustules appear at the site of the previous papule, in this regard, transitional variants are often designated by the term &quot;papulo-pustula&quot;. As a result of the development of a pustule from a papule, the inflammatory infiltrate increases, a cavity with purulent contents of white or yellowish color is formed in the center of the nodule.

A node is a deep inflammatory element that occurs as a result of the destruction of the wall of a sebaceous hair follicle, more often as a result of the development of several comedones located next to each other into pustules. Acute inflammation can last several weeks, even months.
