Acne is an inflammatory skin condition that can cause permanent scarring. The condition is caused by bacteria and is often associated with oily skin or acne prone skin. Acne can affect any area of the body, but is most commonly seen on the face, neck, chest, back and upper arms. There are many different types of acne, and they can be mild or severe. Acne is often associated with other conditions such as rosacea, eczema, psoriasis, seborrhea, and sebaceous gland disorders. Acne is also known to be a side effect of certain medications including isotretinoin, oral contraceptives, antibiotics, corticosteroids, and anticonvulsants.
Acne is a common problem among teenagers and young adults. It is often referred to as teenage acne. Acne is also common in middle aged adults, and can be seen in older adults as well. Acne can occur in any race, and there are no specific factors that predispose a person to developing acne.
Acne is caused by the overproduction of oil from the sebaceous glands. This oil is then released onto the surface of the skin. If the oil is not removed from the skin, it will clog pores and create an environment for bacteria to thrive. Bacteria can then release toxins which cause inflammation. Acne develops when these bacteria and toxins irritate the skin’s surface.
There are several different types of acne. The most common type of acne is called papular acne. Papular acne occurs when small bumps appear on the skin. These bumps are often red or slightly raised. Papules may appear on the face, chest, back, buttocks, or groin. Papules tend to be more painful than pimples, and usually last longer. They can become inflamed and pus filled. In addition, papules are often larger than pimples.
Another type of acne is nodular acne. Nodular acne occurs when large lumps develop on the skin. These lumps can become tender, painful, and swollen. Nodules are usually found on the face, neck, or chest.
Pustular acne is the third most common type of acne. Pustules are fluid filled blisters that are filled with pus. They are typically smaller than papules and nodules. Pustules are usually found on the cheeks, nose, chin, or forehead.
Cystic acne is a less common type of acne. Cystic acne occurs when one or more cysts form on the skin. Cysts are filled with clear fluid, and are typically found on the face, back, or chest. Cysts are usually painless, but can become infected and inflamed.
Acne is also known as acne vulgaris. Acne vulgaris is the most common type of acne. It is also the most common type of acne.
