The main factor initiating the development of light skin was seen as a consequence of genetic mutation without an evolutionary selective pressure. The subsequent spread of light skin was thought to be caused by assortive mating and sexual selection contributed to an even lighter pigmentation in females.
Humans started off as black in Africa, the skin pigment being protection from the sun. As humans moved North, so much melanin was not necessary for protection and it blocked the bodies ability to synthesize vitamin D, which requires UV light. Evolution favored lighter skin, and viola! White people.
At some point, some northern populations experienced positive selection for lighter skin due to the increased production of vitamin D from sunlight and the genes for darker skin disappeared from these populations.
Skin whitening is possible to some extent through various methods: Topical Treatments: Over-the-counter products with ingredients like vitamin C, hydroquinone, and kojic acid can help lighten the skin. Professional Treatments: Chemical peels, laser treatments, and microdermabrasion can also lighten the skin.
Paleness may be the result of decreased blood supply to the skin. It can also be due to decreased number of red blood cells (anemia). Paleness of the skin is not the same as loss of pigment from the skin. Paleness is related to blood flow in the skin rather than deposit of melanin in the skin.
Vitiligo occurs when pigment-producing cells (melanocytes) die or stop producing melanin — the pigment that gives your skin, hair and eyes color. The involved patches of skin become lighter or white. It's unclear exactly what causes these pigment cells to fail or die.
Deficiencies in calcium, vitamin D and vitamin E can cause white patches on the skin. While harmless, these white spots indicate that you need to eat a healthy, balanced diet.
Regular consumption of orange juice can lead to a brighter, more even skin tone, making it an excellent choice for skin whitening and lightening. Rich in vitamin C, lemon juice is a potent antioxidant that prevents hyperpigmentation, removes toxins, and protects against photodamage.
In many tissues, the effects of estrogen are counterbalanced by progesterone. Consistent with this, when melanocytes were exposed to progesterone, melanin production decreased, causing skin to lighten .
Two genes are SLC24A5 and SLC45A2 that lead to skin depigmentation and, therefore, Europeans' pale skin today. The third gene, HERC2/OCA2, causes blue eyes, and it contributes to light skin color and the blonde hair.
The main factor initiating the development of light skin was seen as a consequence of genetic mutation without an evolutionary selective pressure. The subsequent spread of light skin was thought to be caused by assortive mating and sexual selection contributed to an even lighter pigmentation in females.
Average skin colors are seen as most attractive. Typically, tan is the average skin color, making it very attractive to most people. However, the most attractive skin color varies on preference, culture, and sex. A healthy skin complexion and rosy “glow” is always considered attractive.
Vitiligo may flare or spread due to: Stress. Sunburn, cuts, or other skin damage. Chemical exposure.
The earliest documented representative of the genus Homo is Homo habilis, which evolved around 2.8 million years ago, and is arguably the earliest species for which there is positive evidence of the use of stone tools.
In some cultures, lighter skin has been associated with privilege, power, and social status, creating a bias towards individuals with paler complexions. This bias is deeply rooted in historical constructs of colonialism, where lighter-skinned individuals were often viewed as superior or more desirable.
Topping the list is South Sudan, where some of the world's darkest skin tones can be found. The South Sudanese, particularly the Dinka and Nuer ethnic groups, are known for their exceptionally deep, dark complexions. South Sudan gained independence from Sudan in 2011 and has since been building its national identity.
Melanin is generally considered to be the perfect protection against UV-induced photodamage. However, melanin can also have toxic properties, especially after exposure to UVR (73-75).
The major finding of this study is that women (not using make-up) with higher levels of late follicular oestrogen have more feminine, attractive and healthy looking faces than those with lower levels.
Skin bleaching, rooted in complex historical, cultural, and economic dynamics, involves using creams, soaps, and – in today's society – lasers for purposes of a lighter skin tone [2]. The practice of skin lightening has dated to 200 BCE.
Lemon juice is known for its natural bleaching properties, making it a popular choice for skin whitening. When combined with honey, it not only lightens the skin but also nourishes it. Honey has antibacterial properties that help reduce scars and blemishes.
Fruits and vegetables contain lots of vitamins and minerals, fiber, phytochemicals, and other essential nutrients that are great for our health. Eat fresh fruits in the morning on empty stomach to boost physical energy, naturally, detoxify your system, and aid weight loss.
Vitamin C aids in the brightening process by priming the skin cells and making them more susceptible to the effects of Glutathione. Additionally, research suggests that Vitamin C itself may possess some brightening properties.
There are ten major sources of vitamin B12 fruits. These are apples, bananas, oranges, mangoes, strawberries, guava, avocado, pomegranate, kiwi, and blueberries. Apples- Apples rank first in the vitamin B12 fruits list.
The average age of onset of vitiligo is in the mid-twenties, but it can appear at any age. The size and number of patches varies from person to person. The condition tends to progress over time, with larger areas of the skin losing pigment.
Iron deficiency anemia signs and symptoms may include: Extreme fatigue. Weakness. Pale skin.
