Skin Bleaching
What is skin bleaching?
Skin bleaching refers to the use of products to lighten dark areas of the skin or achieve an overall lighter complexion. These products include bleaching creams, soaps, and pills, as well as professional treatments like chemical peels and laser therapy. Skin bleaching reduces the concentration or production of melanin in the skin. Melanin is a pigment produced by cells called melanocytes. The amount of melanin in your skin is mostly determined by genetics. People with dark skin have more melanin. Hormones, sunlight, and certain chemicals also affect melanin production. When you apply a skin bleaching product to the skin, such as hydroquinone, it decreases the number of melanocytes in your skin. This can result in lighter skin and a more even appearance to the skin.
What are the myths about skin bleaching?
‘Skin bleaching merely removes the tan one gets from the sun’. False; darker skin or melanated skin is an appearance by default, there’s no better, lighter skin underneath it. High end products/services used for skin bleaching predisposes one to the same side effects as lower end products. This is true. The duration of use affects side effects. True. Prolonged use (>4 years) of skin bleaching products produces more serious side effects than those used for shorter periods of time. Darker skin is normal skin. It is not dirty skin that requires brightening to make it clean.
Are there benefits of skin bleaching?
There are no specific health benefits to skin bleaching, but it can have a desirable cosmetic effect on the skin when used to treat certain skin conditions. Skin bleaching may also be an unwanted side effect of using a cosmetic product to treat a skin condition.
What are the dangers of bleaching?
Because of the negative health implications and the psychological hold skin bleaching has on individuals; especially of darker skin tones, a number of countries have banned skin bleaching products. In August 2017, the Food and Drug Administration in Ghana banned the importation of all products with hydroquinone.
