We all wish to have flawless skin but as a norm, this is not always so. The human anatomy and genetic makeup are quite remarkable. In almost every individual, the skin within the body region tends to be flawless but with one major exception: the anal region. This brings us to the question, what is the science behind the skin darkness in the anal region? Well, there is quite a number of contributing factors that bring about the darkening of the anal region.
The following is an overview of these factors
The presence of epithelium tissue is considered as one of the major contributing factors as to the science behind skin darkness in the anal region. As a norm, the entire body is usually covered by external epithelium tissue. The digestive system, on the other hand, has an internal epithelium tissue lining the digestive tract up to the anus. These two tissues usually overlap at the anal region and as a result, form a much thicker tissue which tends to be darker in color
This is another major contributing factor as to the skin darkness in the anal region. The skin around the anal region has a high concentration of Keratin; Keratin is responsible for dark skin, and as a result tends to be much darker when compared to skin in other parts of the body
Vascularization also contributes to a certain extent the dark color associated with the anal region. For the anus to perform its function efficiently, it has to be highly vascularized so as to supply sufficient energy and oxygen to the anal muscles which as a norm are in constant contraction so as to avoid leakages. Due to this, the pinkish red tones associated with highly vascularized body sections also contribute to anal skin darkness
As a norm, a lot of friction usually takes place when one is walking. Thighs rub against each other, or the skin rubs against clothes and undergarments: which tend to be tightest around the anal and genital region. As a result of the friction, the skin tends to gradually darken over time
When you shave, hair is not removed from the root and as a result part of the hair is still visible under the skin. This to some extent also contributes to a dark anal and genital region
Skin darkness is considered as being natural but for those who might feel self-conscious about this condition, there are a number of anal bleaching procedures that are quite effective when it comes to skin whitening in the anal region. Go to http://analbleachadvice.com/ to learn more about this.
