Is skin different based on it's color? Does it need specific grooming regimens?
Human evolution has been characterized by a marked reduction in body hair and the increased importance of protection against the harmful effects of solar radiation, and increased potential for skin cancers. People of skin of color comprise the majority of the world's population. Asians comprise more than half of the total population of the earth. There is not a lot of research on how different skin types should care for the amazing differences we all have. Several studies over the past few decades have attempted to decode the underlying differences in skin structure and function based on different ethnic skin types.
However, most of these studies have been on too small of a scale. There has been a recent call for more studies to address epidermal genetics along with observable differences among different racial groups, and the proper medical and grooming practices needed. Several large-scale studies have been conducted recently. The most obvious ethnic skin difference relates to skin color, which is dominated by the presence of melanin.
Melanin, a dark biological pigment found in skin, hair, feathers, scales, eyes, and some internal membranes; it is also found in the peritoneum of many animals (e.g., frogs), but its role there is not understood. Formed as an end product during metabolism of the amino acid tyrosine, melanins are conspicuous in dark skin moles of humans. -WRITTEN BY: The Editors of Encyclopaedia Britannica
Studies show the protection derived from this polymer influences the rate of the skin aging changes between the different racial groups. However, all racial groups are eventually subjected to the aging process. Generally Caucasians have an earlier, and greater chance of skin wrinkling and sagging signs than other skin types. Although in general increased pigmentary problems are seen in skin of color. Although one large study reported that East Asians living in the U.S.A. had the least pigment spots. Changes in the skins biophysical properties with age demonstrate that the more darkly pigmented subjects retained younger skin properties compared with the more lightly pigmented groups. Asian skin is reported to possess a similar water loss to Caucasian skin. Differences in intercellular cohesion are obviously apparent. In contrast reduced natural moisturizing factor levels have been reported compared with Caucasian and African American skin. Increased pores size, sebum secretion and skin surface microflora occur in African American subjects. Equally increased mast cell granule size occurs in these subjects. The frequency of skin sensitivity is quite similar across different racial groups. In conclusion, we know more of the biophysical and somatosensory characteristics of ethnic skin types but clearly, there is still more to learn and especially about the inherent underlying biological differences in skin types.
Dont just take the word of social media influences, commercials, or your aunt who has used everything ontheh market. Genetic studies such as 23andMe have really begun to show us the map of who we are as a person. The skin is the largest organ in the body and requires the most care. Do what you can to learn what's best for your particular skin type. Tata for now.
