Reasons Responsible For Acne

However, sometimes your body suddenly produces an excess of sebum. Since the sebum is oily and somewhat sticky, it may combine with some of the loose cells at the surface of the stratum corneum so that instead of sloughing off, they produce a paste-like material. This paste may then wedge itself into an open hair follicle (pore) and there set, compact, and harden into a solid, hard-to-remove wad that partially plugs up the mouth of the pore.

At the same time, there appears to be a change in the constitution of the cells that line the hair follicle canal, and this may be an even greater problem than the surface plugs. Apparently, through a series of hormonal events that scientists do not fully understand, some or all of these internal cells become sticky. Normally, as they dry, the cells lining the follicle are swept out by the emerging sebum. But once they become sticky as a result of those hormonal or other changes, the sebum can no long rinse them out. Instead, they adhere to the sides of the canal, adding’ to the partial blockage.

These partial blockages are called microcomedones. The first impact of these microcomedones is that they force the canal to dilate, which enlarges the pores at the skin’s surface, a condition typical of, acne sufferers. Apart from their looking unattractive, these enlarged pores are something of a mixed blessing. On the one hand, they allow more of the sebum to emerge, thus delaying or reducing the amount of internal sebum buildup. On the other hand, the larger mouths the pores are more likely to gather plugs from the cell-and-sebum mixture on the surface of the stratum corneum.

As more sebum builds up inside the pore, if the partial blockage is generated from the external ?paste? of cells and sebum and is the. Fore near the surface, you start to see blackheads. The dark color blackhead comes from a pigment in the sebum, not from dirt. Nevertheless, they look ?dirty? and are unsightly.

If the blockage is generated by sticky internal cells and is therefore further down the canal, you will see only a slight reddening and, a bump. An acne spot is sure to erupt eventually, but so far it is still too far down to be visible. In profusion, these deep down microcomdones give rise to the bumpy feel of the skin even when the acne h not yet broken out.
