Acne is a very common skin disorder caused by overproduction of sebum (oil) in the sebaceous gland. This gland is a part of Pilosebaceous unit which also has hair and hair follicles as other components. Our skin has these units everywhere except palms, lips, soles etc. In other words wherever you have hair it is because of these glands. However in some parts of body like face and upper neck their no. is high. Because of this reason we have more acne in these parts of the body than in other parts.
Due to several physical conditions like puberty and pregnancy these glands are triggered to produce more oil than what can be easily cleared by the pores. This results in formation of pimple and later turn into acne.

Types of Acne
Acne can be classified into two main categories; Mild Acne and severe acne

Whiteheads: It appears in the form of white spots on the skin. Usually when dead cells and oil are trapped at the blocked pores, we notice the appearance of white spots. These are quite temporary and heal themselves. white heads can be popped with special care but do not try unless you are sure to do it correctly.
Black heads: When pores are not blocked completely and allow some of the sebum to spill onto the outer surface of skin, it results in formation of black heads. Skins pigments react with oxygen and turn them black in color, hence the name.
Papules: these are inflamed version of either of the above conditions. Usually red in color papules need some treatment.
Nodules: this is a severe condition with some hard lump under the skin .It is usually painful and leaves a scar even after treatment.
Cysts: they are larger than nodule and are usually filled with pus instead of hard lump. A severe form of acne that needs immediate attention.
While there are various other Types Of Acne depending upon their severity, we’ll focus on those which are the most common and are treatable by natural methods.
