Acne vulgaris, in simple words, is known as 'Pimple' which is usually seen on the faces of teenagers. Acne is a skin condition that is generally characterized by a little bulged structure filled with pus in most cases.
The most common areas in the human body that are affected by pimples are
- Face (mostly cheeks and forehead)
- Chest, and
- Back (mostly at the top of back)
Pimples are most common in teenagers, they can also affect adults but rarely.
The mechanism behind the formation of acne:
The sebaceous glands which are present under the skin generally secrete an oily substance known as sebum so as to protect the skin and hair from drying.
The hair follicles under the skin generally shed the dead skin cells which are carried out of the body by sebum through the pores of the skin.
In some instances, excessive sebum is produced by the sebaceous glands along with excessive dead skin cells. These dead skin cells bind together to form a complex which clogs the pores of the skin.
In addition, the bacteria which is generally present on the surface of the skin get nourished in the clogged pores which ultimately leads to inflammation.
This is the mechanism of the formation of pimples on the skin.
