Dark spots, also known as hyperpigmentation, is a common skin problem that can increasingly grow as age progresses. In this condition, Melanin, which is the chemical that gives the human skin its colour, is excessively produced in one area, leading to freckles, melasma or uneven skin tone.
The skin pigment of humans varies widely in range from the deepest brown tones to the whitest hues possible. The colour of a human skin is the result of several genes, being inherited by the parent's DNA from both of their biological parents, and being influenced by sun exposure. In general, there are four different skin colors that are considered normal. Humans who have a recessive gene or two may also have a darker skin than one with the desired skin tone.
Skin pigmentation can sometimes be difficult to know without having a basic understanding of genetics. A doctor or dermatologist can be very helpful if you are trying to determine the cause of your skin's pigmentation and if you have an idea of what type of skin you have. You can also research on the web about the pigments of other peoples' skin. Once you know what skin you have, you will be able to make an informed decision about the treatments that are best suited to your specific condition. Skin colour and the pigments that it contains are extremely important and need to be taken into consideration when considering the treatment options available for your skin.
