There are several different types of pimples which may develop. The most common types of them are:
A whitehead pimple which is also called a milium is a small lump that forms when dead skin cells, oil, and bacteria become trapped within one of your pores. The white heads are mild forms of pimples. They are small, round bumps filled with a white, creamy liquid. Whiteheads are the result of blocked pores. The oily portions of your face—such as the nose, chin, and forehead—are the most prone to whiteheads. The trapped oil in the skin swells and turns into a white lump and is known as a whitehead. They usually are of white or yellowish colour, as they are not exposed to oxygen. A good fact about whiteheads is that they can be avoided with a combination of lifestyle changes and treatments. Even when whiteheads appear it is easy to treat them. Products rich in benzoyl peroxide are the best to treat whiteheads.
A blackhead is a small bump that appears on your skin due to clogged hair follicles. These bumps are called “blackheads” because the surface looks dark or black. Common and annoying, blackheads are said to be the first stage of acne that forms when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil, called sebum, which helps to keep your skin soft. Dead skin cells and oils collect in the opening to the skin follicle, producing a bump. When the skin over the bump opens, exposure to the air causes it to look black and a blackhead forms. There are simple remedies for blackheads but it needs your patience to reap the results. A regular skin care routine also helps you to keep off blackheads.
A papule is an area of abnormal skin tissue that is less than 1 centimetre around and has distinct borders appearing in a variety of shapes. Papules occur when the wall of a hair follicle breaks and caves in – the visible inflammation is due to white blood cells rushing in. Papules are often called skin lesions, which are essentially changes in the colour or texture of your skin. Often, papules cluster together to form a rash. These can be caused by a number of conditions that affect the skin, but dermatitis, chickenpox, and eczema are among the most common. The treatment for papules is similar to the treatment for the other acnes like whiteheads or blackheads, but be mindful not to squeeze them.
A pustule is a small bump on the skin that is filled with fluid or pus in the top layer of skin or beneath the skin. These bumps can form on any part of the body, but they are most common on the back, neck, chest, and face. Pustules frequently form in sweat glands or hair follicles. Put somewhat more simply, a pustule is a little pocket full of pus. They are easily identifiable as they appear as small bumps on the surface of your skin. The bumps are usually white, or red with white in the center. The bump may be painful to the touch and the skin around the bump may be red and inflamed. Popping a pustule is often tempting as it reduces the size, but it in long run it may leave back scars and trigger infections. So, hold back your hand when you feel like squeezing a pustule.
A nodule is a growth that forms under your skin. A nodule may be filled with inflamed tissue or a mixture of tissue and fluid. Although they are grouped together with whiteheads, blackheads, and pustules, that may feel like a stretch to those who suffer from them. Nodules are larger than the typical pimple bumps, and they look like raised ovals covered by skin. The collection of coloured fluid within a nodule may indicate an infection. Nodules are usually harmless and are made of inflamed tissues that collect together to form a lump.
A cyst is a type of acne characterized by deep and inflamed breakouts. These blemishes that follow will be large, inflammatory and cause very soft red lumps of cysts which are formed under the surface of the skin that generally lead to pain. These cysts that are filled with fluids contain dead cells, bacteria and white blood cells. They generally appear on the face, back and chest. There is no special age for this acne cyst to occur but it is most commonly found in teenagers more than people of any other age group. Cystic acnes are best dealt with the guidance of a dermatologist. Squeezing a cystic acne may lead to permanent scarring.
