What is Acne?

Acne vulgaris is very common dermatoses. It appears at teenage years, when the sebaceous glands are the most energetic. In the period of  pre-adolescent, seborrhoea oleosa and also  some comedones normally come out as fore-runners of the diseases. In the age of  twenty, it decreases gradually, and is again appear particularly in women after the age of 28, or so (post-adolescent acne), since they frequently stop producing children (family planning) and periods may suit scanty by that age. It also occurs in both girls and boys; in the final, in a fairly severer form.

For the growth of acne, also seborrhoea, the hyperkeratosis of the pilo-sebaceous ostia is an important pathogenic factor. A keratinous-cum-sebaceous plug is formed in the follicular neck resulting that it narrowing and sometimes blocking of the tube.A well-developed rising hair interferes with the group of keratinous and sebaceous matter. The growing hair plays the role, as it were, of a spike. That is why acne never occurs on the scalp, and only rarely, on the beard region despite seborrhoea being present in these areas.
