Description
Technical field
The present invention relates to a kind of Whitening, spot essence and preparation method thereof, belong to cosmetic field.
Background technique
Pigmentation and color spot Producing reason are more complicated, such as inherent cause, endocrine disorder, environmental pollution, ultraviolet
Line irradiation etc., pigmentation and color spot caused by either any reason, be after all as caused by melanin pigmentation,
Therefore the main path of the light spot of skin-whitening is to inhibit the generation of melanin.Inhibiting the generation of melanin, there are many methods, such as press down
The vigor of tyrosinase processed, the transfer, Scavenger of ROS or the free radical that inhibit melanosome reduce ultraviolet light irradiation, prevent oxidation
Reaction generation etc. is the effective ways for reducing melanin and being formed.
By adding various whitening spot-removing substances in cosmetics color spot is mitigated or eliminated, to reach whitening in people
The effect of nti-freckle.Whitening spot-removing ingredient contains mercury and mercuric compounds or quinhydrones earlier, since toxicity, irritation are larger, at present
Disabled by country.People start to explore traditional Chinese medicine later, minerals (such as pearl powder), vitamin C, hydrogen peroxide are used for
Freckle removing and whitening, but single effect cannot combine whitening and light spot, and it is thinning to will lead to after keratoderma,
Cause the symptoms such as subsequent allergy inflammation.Therefore, it is mild to develop and develop a kind of pair of skin safe, effectively takes into account whitening and light
Spot, moreover it is possible to which the cosmetics of anti-inflammatory are particularly necessary.

The movement rate of melanosome, by inhibiting the transfer of melanosome come the whitening colour of skin.
Preferably, the 3-o- ethylascorbyl, trade name VC ethylether, by the work for inhibiting tyrosinase
Property, achieve the effect that skin whitening.
Preferably, the mixture a, trade name Brightenyl comprising didextrose base gallate, glycerol, water,
In, didextrose base gallate is the whitening active object that a new generation is activated by skin itself, has splendid antioxidant effect, and pass through
The transfer of melanosome is inhibited to carry out skin whitening.
Preferably, the mixture b, trade name IMMORTAL WA (L) comprising water, butanediol, tremella
(TREMELLA FUCIFORMIS) extract, Phenoxyethanol.
Preferably, the mixture c, trade name MAGNOLIA EXTRACT comprising water, butanediol, Tiannu Magnolia
(MAGNOLIA SIEBOLDII) extract, wherein Tiannu Magnolia (MAGNOLIA SIEBOLDII) extract is able to suppress inflammation
Inflammation factor 1L-1a and nitric oxide production generation have good antioxidation, and the transfer for being able to suppress melanosome comes, simultaneous
Has the effect of Whitening, spot anti-inflammatory.
It further include the moisturizing of following weight percent as the preferred embodiment of Whitening, spot essence of the present invention
Agent: butanediol 0.1~15%, carbohydrate isomer 0.01~10%.
It further include the thickening of following weight percent as the preferred embodiment of Whitening, spot essence of the present invention
