Because in advertising we usually see a beautiful Korean or Chinese woman without age. We are assured that following the skincare tips of Asian beauties will help you keep your skin looking young and beautiful for years to come-best lotion for black skin.
However, the main catch is that European women have their own skin, and most importantly, a different type of aging than Asian beauties. Women from Europe often have sensitive skin, prone to allergic reactions and premature aging.
Do you know the secret of Asian youth? Oriental beauties - Koreans, Chinese, Japanese - are characterized by a muscular type of aging. And with it, the skin of the face remains even and smooth for quite a long time, a clear oval of the face is often preserved until old age. In European women, the skin is prone to a finely wrinkled or deformation type of aging, so the first signs of aging sometimes appear quite early - even at a young age, there are often small wrinkles or the oval of the face “floats”.
SKIN DIFFERENCES
The key difference between ethnic groups from each other is skin color, which is determined by the ratio of three pigments: eumelanin (pheomelanin), carotene, hemoglobin (and oxyhemoglobin) of blood. The main pigment that determines the color of the skin, eyes and hair is melanin, which is formed in special skin cells - melanocytes. The number of these cells is the same in all races. Then why are some people completely white and others completely black?
The fact is that in people of different ethnic groups, these cells are genetically programmed to work differently and produce different amounts of melanin. This fact is of great importance when creating cosmetics. For example, the inhabitants of Asia have relatively fair skin, but it is prone to pigmentation. In addition, Asian skin is much thicker than that of Europeans, so local cosmetics contain a large amount of whitening components that are quite aggressive for us, but quite comfortable for Asian women. Their skin tends to be more oily, while the European region is dominated by sensitive skin.
Another difference is the photosensitivity of the skin in different ethnic groups. So, with equal exposure to ultraviolet radiation, some will have a tan, others will burn. Photosensitivity also plays a role in photoaging and skin cancer. When investigating the ethnic characteristics of the skin, it is necessary to take into account the fact of population migration. So, most of the inhabitants of Israel and Australia are white people living in conditions of intense exposure to the sun. Genetically, they don't produce much melanin, and the stratum corneum thickens considerably as compensation. Their skin is rough and denser compared to the inhabitants of the European region. So the inhabitants of Israel and Australia can afford more intense exposure to the skin of ultraviolet rays.
When developing cosmetics by ethnic type, the fact that melanin, among other things, is a universal and very active antioxidant, is always taken into account. Therefore, the use of antioxidants in cosmetics is primarily indicated for white-skinned people, especially those who live in regions with an active sun or travel to such regions on vacation.
The structure of the stratum corneum of the skin also has ethnic characteristics. Thus, ethnic groups with dark skin have 30-50% more cells in the stratum corneum than owners of light skin. However, the thickness of this layer is the same, which means that dark skin is much denser than white and less permeable. The electrical resistance of dark skin is twice that of light skin. This is important for the creation of "charged" cosmetics for hardware cosmetology - products that are compatible with the action of electroprocedures: electrophoresis (iontophoresis), galvanization, microcurrent therapy, myostimulation, lymphatic drainage.
RESEARCH IS IMPRESSIVE
Recently, an experiment was carried out: samples were sequentially taken from the stratum corneum of people of different ethnic groups using adhesive tape. Thus, we studied how water loss in the skin increases with its thinning. The following results were obtained: significantly more samples had to be “taken” from dark skin in order to double the loss of water compared to white skin. At the same time, dark skin recovered much faster than white. This is due to the fact that there are much more cells in the stratum corneum of dark-skinned people and they are more strongly linked to each other.
The smallest number of cells in the stratum corneum is among the indigenous people of Asia. These facts are important when developing peels and working with active ingredients that can cause irritation or an allergic reaction. Therefore, the skin of Caucasians and
Asian residents are much more sensitive, and the skin of northern Europeans is also prone to dehydration. The skin of the Negroid race is characterized by increased production of sebum and a tendency to acne.
Scientists have made interesting conclusions by studying the lipid composition of the stratum corneum of the skin. It turned out that the largest difference in the qualitative composition of lipids is maximally between the Japanese and Europeans. From this it follows that they need creams with different composition of ingredients. In the same study, it turned out that photoaging, wrinkling, flabbiness are much more relevant for Europeans. It has also been found that other mechanisms of defense against damaging ultraviolet radiation, different from the melanin system, work in the Asian population.
Studies on sensitive skin have also shown that skin reacts differently to cosmetic ingredients depending on ethnicity. For example, Asians are much less tolerant of certain acids than Europeans and those with dark skin. Europeans are significantly more sensitive to wind. It is for them that cosmetics that protect against the adverse effects of wind and cold are relevant. And for the inhabitants of Asia, the priority is the fight against pigmentation and the negative effects of the sun. White-skinned Europeans have significantly more wrinkles compared to the indigenous population of Asia. Wrinkles around the eyes and early aging of the skin of the eyelids are a feature of the inhabitants of Europe. Cosmetics that slow down wrinkled aging, remedies for edema and dark circles under the eyes are relevant for them. The skin of African Americans turned out to be minimally sensitive to the action of external factors and aging.
SUMMING UP
In people with dark skin, dermatological manifestations of photoaging are detected later than in people with fair skin. Wrinkling and flabbiness of the skin are in the lead in whites. Hyperpigmentation and uneven skin tone are signs of aging in dark skin. For different ethnic groups, different physiology of the stratum corneum has been scientifically proven. In people of Asian descent, skin moisture loss is minimal, which is explained by the qualitative difference, compared with Caucasian groups, in skin lipids. In addition, Asians have significantly higher levels of ceramides in their skin.
This indicates the presence of a significant difference both in the physiology of the skin and in its chemical composition and, as a result, the need for creams with different compositions. The skin of oriental beauties is as sensitive as possible to chemical irritants, it tolerates peelings worse. In addition to genetic characteristics, it is necessary to take into account the climate and geographical location of ethnic groups, as well as the migration history of their ancestors.
Approach the choice of cosmetics wisely, and not on emotions, and you will not be disappointed!
