Of the assumption that the white color is more beautiful and desirable appearance by the women, the color black, brown, yellow and white are determined by many factors. To understand about skin bleaching process, we must understand what skin is it?



The skin is an organ wrapper around the outer surface of the body (the heaviest organ, 16% of the body weight of approximately 2.7 to 3.6 kg, an area of ​​about 1.5 to 1.9 square meters, a thickness between 0.5 to 6 mm). In embryological skin comes from two layers:
  • The outer layer; epithelial layer of the epidermis which is derived from the ectoderm 
  • The inner layer; mesoderm is derived from the dermis or korium which is a layer of connective tissue (Ganong, 2008).

In histopathologic skin composed 3 main layers, namely: 
  • Layer of the epidermis, the outer layer of skin is thin and avascular, composed of stratified epithelium flattened horns, cells containing melanocytes, Langerhans and Merkel, has a different thickness on the body, thickest on the soles of the feet and hands, is composed of five layers:
  1. Stratum corneum, composed of keratinocytes cells that can peel and replace; 
  2. Lusidum stratum, translucent lines, there is a thick leather soles on the feet and hands; 
  3. Stratum granulosum, there Langerhans cells and 3-5 layers of polygonal cells; 
  4. Stratum spinosum, which has the role tonofibril maintain cell cohesion and protect against abrasion; 
  5. Stratum basale, perform mitotic activity in constant cell renewal of the epidermis (28 days migrating to the surface), (Wasitaatmadja, 1997)
  • Dermis, (true skin) is composed of connective tissue that supports the epidermis and subcutaneous tissue connecting with, consists of two layers:
  1. Papillary layer, contains a thin connective tissue rarely 
  2. Reticular layer of thick, composed of dense connective tissue
    In old age the intersecting collagen in bulk and reduced elastin fibers causes the skin to lose elasticity and become occurring wrinkles, dermal functions: supporting structure, mechanical strength, supply of nutrients, resist shearing forces and the inflammatory response. (Wasitaatmadja, 1997)
    • Subcutaneous layer, the dermis layer under that consists of fat, a layer of connective tissue that connects the skin to the underlying tissue loose, function: attached to the basic structure, heat insulation, spare calories, control body shape and mechanical shock absorber. (Wasitaatmadja, 1997)


    The skin has many functions as follows:
    1. Protective function or protection, cover the body tissue on the inside of the wound and germ attacks, the outermost layer covered with a thin layer of fat, makes skin waterproof, withstand body temperature, hold a small wound, preventing chemicals and bacteria into the body and block the stimulation physical ultraviolet rays of the sun;
    2. Receiver function stimulation, tentacle sensation through nerve endings, sensory stimuli associated with pain, heat / cold, pressure, and vibration grope.
    3. Thermostat function (thermoregulation), set the temperature through capillary dilation and construction vessels and autonomic nerves are affected respiration (average temperature of 98.6 degrees Fahrenheit, the heat will be lost by evaporation of sweat.
    4. Expenditure function (excretion), the skin secrete a substance (salt, iodine and chemicals eat it) through perspiration and evaporation of sweat forming airtransepidermis as unconscious.
    5. Storage function, storing fat in fat glands;
    6. Limited absorption function, absorb certain substances that are soluble in fat, such as hormones. Absorption through the mouth of the bladder into the channel gland hair ointment, towards the vessel wall into the bloodstream and then to the other organs;
    7. Functions supporting performances, functions associated with the appearance (beauty) that looks smooth, white and clean, and can express emotions such as flushed skin, pale hair and enforcement muscle contraction.

    Diverse skin color has its own uniqueness, in which skin color is determined:

      • Factors oxyhemoglobin is red; 
      • Factors that reduced hemoglobin bluish red 
      • Factors melamine is brown 
      • Factors keratohyalin opaque appearance; 
      • Factors stratum corneum has a yellowish white or grayish.
              Melamine pigment that determines the color of the skin (the factors of race, people and the environment), made ​​of tiosin (amino acids) tyrosine is converted to oxidized grain brown melamine, this process went more smoothly at high temperatures (ultraviolet). number, type and size of melamine will determine skin color variation.
