Acne: An Inflammatory Skin disease
Acne Vulgaris is the most common of all skin diseases that affects about 80% of people between the age groups of 12 to 24 years. The symptoms can vary from quite mild to extremely severe.
What Is Acne?
Acne is an inflammatory skin disease originating from sebaceous glands and hair follicles. It is a disorder of the oil glands in the skin. Oil glands or sebaceous glands, which are present in each hair follicle or tiny pits of the skin, secrete oil that lubricates the skin and keeps it soft and smooth. If these oil glands become over active and produce excess of oil, this oil stimulates bacteria present on the skin to multiply and cause surrounding tissues of the skin to become inflamed. Inflammation is characterized by redness, swelling and pain at the site of infection.
Types Of Acne
There Are Two Main Types Of Acne
1. Non- Inflammatory
2. Inflammatory
1. Non-Inflammatory Acne: In the beginning of acne formation it is only the smallest type of lesion, known as micro comedo.It is so small that it cannot be seen with naked eyes. When micro comedones are only non inflamed skin blemishes, they are called comedones - either a whitehead (closed comedo) or a blackhead (open comedo).
* Whitehead: When the trapped sebum and bacteria stay below the skin surface they make an enzyme that breaks down sebum into a substance called “free fatty acids”, which is very irritating, and can cause swelling, redness and puss formation. This is called a whitehead (closed comedo). Whiteheads look like tiny white spots, or they may be so small that they can’t be seen by naked eye.
* Blackhead: When the pore opening to the surface is blocked by excess sebum secreted by the oil gland; which contains the skin pigment melanin, it gets oxidized and turns a brown/black color, giving rise to a blackhead (open comedo). It is not due to dirt or dust as it is dried oil and cannot be washed away.
2. Inflammatory Acne: - Inflammatory acne is a more chronic form of the problem. It is characterized by redness, swelling, pain and puss. There are four main types of inflamed acne blemishes.
* Papules: A Papule is a red and inflamed lesion on the skin’s surface. It occurs when there is a break in the follicular wall, allowing bacteria to spill into the dermis.
* Pustules: A pustule is a typical pimple — with a whitehead. It forms when white blood cells come on the surface of the skin. The white cap on the pustule is puss, sebaceous matter and cellular debris.
* Nodule: Nodules are largely inflamed lesions, with hard painful lumps under the skin. It can be sore to the touch.
* Cyst: Cyst acne is the most severe and painful of all types of acne. They are very large, inflamed lesions and feel like soft, fluid filled lumps under the skin’s surface. It may cause scarring.
Acne can make you feel anxious or depressed but with good management and appropriate treatment on time most people are able to control their acne.
