[background technology]
Beauty treatment skin is sick to be learned as a new branch of science, and Along with people's improves constantly the requirement of U.S.A and embodies its importance day by day in recent years.Because molecular biology, immunologic further investigation, the sick learning of beauty treatment skin obtained some new developments aspect whitening and speckle dispelling.
Gloomy skin and mottle are that melanocyte is in the uneven distribution of skin surface and the result who gathers.Melanin is that to be present in the melanocyte of stratum basale synthetic, and forerunner's tyrosine generates melanin in the melanosome under the tryrosinase effect, and this melanin unusual increasing in epidermis makes the patient that chloasma take place.Melanin is most important pigment in the skin, and it determines our colour of skin.Simultaneously, melanin also is the natural defence system of human body skin, can resist the injury of ultraviolet to skin.But when melanin produces too much or skewness; But can cause pigementation; Form black speck, influence appearance, once skin was dark and gloomy, the fair and clear degree of the increase colour of skin except that the method for speckle is improved with bleaching for people; Mainly be to float black speck on the face, stronger bleaching effect all arranged as retinoic acid, hydroquinone compositions such as (hydroquinone) with powerful ingredient.Yet; Use bleach can destroy the sebum film of skin surface; If during this period, skin receives the stimulation of factors such as ultraviolet radiation, endocrine disturbance again, then the function of its self-protection meeting doubling effect; Make melanocyte discharge more melanin, thereby cause more serious pigementation phenomenon.Along with the progress of modern science and technology, people bring into use milder, effectively Skin whitening care cosmetics reaches and causes the white temporary wish of skin.Through the activity of restraint of tyrosinase, reduce melanic generation, thereby prevent new pigementation, it is dark and gloomy to improve the skin that causes because of Exposure to Sunlight or endocrine disturbance, increases bright and clean degree of the colour of skin and well-balanced degree, and desalinates black speck gradually.
Can be divided into two types from the mechanism of action of known Melanin inhibitor:, suppress melanic generation 1, to the cytotoxicity of melanocyte; 2. melanic generation in the obstruction melanocyte.
Also there is not a kind of generally acknowledged additive of spot-removing function safely and effectively on the China market at present.The freckle effect of nearly all cosmetics is very little; And some speckle dispelling product is for speckle dispelling or light speckle purpose; Add harmful substances such as heavy dose of hydroquinone or aminomercuric chloride, cause part consumer serious allergy or the irreversible hydrargyrum speckle incidents of disfeaturing such as (mercurialism) to occur.
Therefore, the research to safe and effective whitening and speckle dispelling functional additive is the problem that the beauty and make-up industry is paid close attention to always.
