Those whose Ethnic background are from South Asia i.e. Indian, Pakistan, Bangladesh, etc; have much darker skin than their northern caucasian counterpart because they have an increased amount of melanin in the skin. Melanin is specifically the pigment in the skin and it protects the skin from sunlight. This actually helps to keep Asian people looking younger than people with white skin. The melanin pigment also slows down the aging process. However as Asian peple age their skin can conceive unbalanced pigmented. This can be seen as darker patches. Unbalanced pigmentation can also be caused by swelling or irratation. If a part of the skin becomes inflamed or red due to being bit by an insect or from an acne pimple, once the redness or inflammation subsides a brown area can be left behind.

Asians although in general are no more oily than caucasian skin but according to dermatologists, Asian women tend to have more oilier skin than recent Asian immigrants. Some dermatologists contribute this on the grounds that there is higher fat content in the diet. There is a theory that diet does not directly affect skin condition, except when it is poor enough to affect one's overall health.

However leading Skin Therapist refute this theory that the internal workings on the human body does contribute to what goes on externally and this will result in unexpected pimples signaling stress, hormonal imbalance, or internal health problems.

And that too much unhealthy food consumption can appear to affect acne breakouts by contributing to an overall physiological imbalance which in turn will cause an increase in the skin's oil production which can cause acne breakouts.
