Acne develops from clogged pores (comedones). Although it can emerge virtually anywhere on the body acne is mostly found on the face. Many forms of acne can be differed. It varies by strength from mild to severe. Mild acne is the most common form. It is usually self-treated and easy to handle. More severe acne breakouts require professional supervision.
Although pimples are the most widespread form there are other forms of acne. They can be divided into two groups, namely, non-inflammatory and inflammatory acne.
Two types of non-inflammatory acne (aka clogged pores or comedones) can be specified: fully clogged pores (closed comedones, whiteheads) and partly clogged pores (open comedones, blackheads).
Closed comedones or whiteheads appear when hair follicle is blocked underneath the skin. This acne eruption looks like tiny whitish bumps right under the skin.
Open comedones or blackheads appear when the clog enlarges itself and breaks through the skin surface. Such blocked pores are dark by color due to melanin build up. Amazingly, blackish appearance has nothing in common with debris or dirt.
Most skin conditions are triggered by accumulation of sebum and dead cells near the hair follicle, leading to pore blocking. Clogged pore inflammation can be caused either by bacteria infection or irritation from squeezing. You can tell inflammation by reddening, swelling and pain. Four types of inflamed acne can be specified:
1. Papule is the mildest form of inflamed acne. It looks like a small solid pinkish bump and is frequently gentle by touch. Papules are considered an intermediary between inflammatory and non-inflammatory acne.
2. Nodules are big aching lesions. Acne of this type is filled with fuss and sits deep in one’s skin. It occurs when comedo expands further to skin, which activates the immune defense producing pus.
3. Pustules are tiny round lesions resembling papules. Though, they are often inflamed to a large extent and fester. In this case inflammation is caused by chemical irritation from sebum components (e.g. fatty acids) but not by bacteria.
4. Cysts are extremely large and inflamed acne. Indeed, they are referred to as the most severe form of acne. Cysts can be depicted as tender by touch, fluid-filled bumps under the dermis surface. They are really painful. Initially, cysts develop similarly to nodules: they stem from the deep break in the follicle wall. Subsequently, a membrane forms around the infection that has affected the skin. Then cyst starts its way to the surface injuring wholesome skin cells and destroying the follicle. This inevitably leads to scarring.
Clogged pores are initial forms of inflammatory and non-inflammatory acne that require proper treatment.
