TYPES OF ACNE
Acne is characterized into two main groups’ i.e. Non-inflammatory acne and inflammatory acne. Non-inflammatory is also known as comedones, includes blackheads and whiteheads, and inflammatory acne, which includes papules, pustules, nodules, and cysts. The clear difference is that non-inflammatory acne is not red and painful because the body has not yet responded to an infection with infection-fighting white blood cells. Inflammatory acne is all that of painful, deep, red and swollen, it often hurts on many levels. It might last for weeks to months and leaves temporary dark marks and hardly, permanent scars, so it’s very important to treat it early.
When the trapped sebum and bacteria stay below the skin surface, a whitehead is formed. Whiteheads may show up as tiny white spots or they may be very small that they are invisible to the naked eye.
A blackhead occurs when the pore opens to the surface and the sebum, which contains the skin pigment melanin, reacts and turns a brown/black color. It is not dirt and cannot be washed away. Blackheads can last for a long time because the contents very slowly drain to the surface.
A papule occurs when there is a break in the follicular wall. These are pink or red dome-shaped bumps, varying in size from a pinhead to half an inch. White blood cells rush in and the pore becomes inflamed. They are usually painless unless scratched or picked. Like all pimples, papules are the result of an increase in oil and bacteria inside the pore trapped by dead skin cells.
Pustules form when a deep inside a pore traps oil and bacteria, attracting white blood cells to fight the infection. Pus is simply a collection of dead white blood cells. Pustules have a yellow or white pus-filled center with a red base. The greater the inflammation, the redder and larger the pustule will be.
Nodules are bigger than pustules and papules and it is formed deeper within the skin. They feel solid to the touch and can be quite painful. They grow when oil and bacteria deep inside a pore spreads, infecting adjoining follicles. Nodules can harden into deep cysts and may leave deep scars, on many levels.
