A large number of oil producing glands called 'sebaceous glands' are present under the skin on the face, back, chest and shoulders. During puberty or menopause due to the influence of the sex hormones, which are produced in male and female, these glands become more active and produce an oily secretion called 'sebum'. The sebum makes the skin more oily. The excessive sebum clogs the skin pore or the pit of the hair follicle forming acne.
The blocked pore or acne acts as an excellent habitat for bacteria. The bacterial infection causes inflammation (red, painful swelling of the infected area) of the clogged pore or hair follicle leading to the eruption of pimples.
Vata and kapha are two main doshas, which are involved in the eruption of acne and pimples. Rakta dhatu or blood also plays an important role in formation of acne.
When the vata gets vitiated due to unhealthy diet and lifestyle, it affects the other two doshas (kapha and pitta) to aggravate them.
Aggravated pittaaffects rakta dhatu or blood. The vitiated blood affects the skin and causes excess secretion of oil from sebaceous glands. Kapha has a sticky property. The aggravated kapha imparts stickiness to the oil produced by sebaceous glands of skin. Thus the thick sebaceous plugs are formed in skin pores and hair follicles leading to eruption of acne.
