Really, use biochemical enzyme process to filter out the Chinese medicine extract of 7 kinds of Whitening, spots, and compatible combination prepare Chinese medicine whitening spot-relieving cream,
Through zoopery and normal individual trial experimental verification, it is safe and non-stimulating, Whitening, spot is respond well.
One, Cavia porcellus whitening effect investigates experiment
Taking each 10 of black Cavia porcellus male and female, body weight is 250~350g, divides 5 groups, often group 4, and respectively embodiment 1 is low
Dosage Chinese medicine skin whitener group (1%), middle dosage Chinese medicine skin whitener group (3%) of embodiment 2, the high dose Chinese medicine whitening of embodiment 6
Frost group (5%), positive arbutin skin whitener group and blank group.Administration group becomes the unhairing of 3cm × 3cm size in both sides, back shaving
District, takes experiment reagent by swab stick uniform at arranged on left and right sides dermal application, every day 2 times.Naive animals to take off in both sides equally
Hair, and ensure that other experiment conditions compare with being identically formed of experimental group.
In Cavia porcellus feeding process, to strictly control indoor temperature and be maintained at about 25 DEG C, relative humidity be maintained at 50%~
Between 60%, every Cavia porcellus is taken food feedstuff 10~15g, Radix Dauci Sativae or vegetable 10~15g every time, the endless supply of water.
After 28 days, take guinea pig skin living tissue, fix with 10% formalin, paraffin embedding, cut into slices, observe.Right
Section after ferrous sulfate dyeing carries out microscope and takes pictures (as depicted in figs. 1 and 2), uses Image-Pro Plus6.0 afterwards
Software, to analysis of being taken a picture, uses optical density/section area and optical density/melanocyte area to characterize melanin content.Each
40 photos of slide random shooting carry out processing statistical analysis.Result such as following table:
Table 1 different group contrast of melanocyte value after ferrous sulfate absorption process dyes
Note: * represents that P < 0.05, * * represent that P < 0.01, * * * represents P < 0.001, n=40.
From result above it will be seen that either from optical density/section area or the angle of optical density/melanocyte area
Degree is analyzed, and blank group is compared with experimental group obvious difference, same group of experiment female and male between difference not
Greatly, also illustrate that this Chinese medicine skin whitener will not have sex selectively acting.Positive arbutin group and middle dosage group (embodiment 2), height
But the result of the Chinese medicine skin whitener of dosage group (embodiment 6) has difference hardly differs;Simultaneously all than low dosage (embodiment 1)
Action intensity is high, can illustrate that the whitening function of this Chinese medicine skin whitener is relevant with the content of Chinese medicine extract from this result.
Finding out (such as Fig. 1 and Fig. 2) from made slide, collagen fiber are red, muscle fiber yellow, and melanin presents green to blackish green,
Melanocyte is distributed mainly on inside corium and epidermal junction and hair.Low dose group and the hair of blank group as seen from Figure 2
In capsule and hair, melanin content is the highest, and concentration is compared in distribution;Comparing of basic, normal, high three dosage, it can be seen that melanin
Content is dense to be declined successively, and the Rhizoma Imperatae core pigment of middle dosage and high dose group then becomes obvious rareness, at epidermis
Pigment content is relatively low.Result shows that Chinese medicine skin whitener whitening effect is good.
Two, normal individual trial experiment
Selecting 4 volunteers having mottle, skin health is without photosensitivity, without cosmetic allergic contact dermatitis history, medicine-less allergy history.Real
Before testing beginning, use CBS-902 skinanalysis apparatus detection mottle melanocyte, primary data can be obtained as absolute reference value.Often
Chinese medicine whitening spot-relieving cream and the commercially available whitening product 1(nature hall snow embodiment 2 prepared after it morning and evening cleaning skin moisten fair-skinned white crystalline substance
Color frost), the commercially available whitening product clear skin whitener of 2(Avene), with about 0.025g/cm2Amount uniform application in test position, continuously
8 weeks.Experiment detects the change of mottle melanin content every three days with CBS-902 skinanalysis apparatus after starting, and does according to change
Go out curve.Volunteer through 8 weeks experiment after skin pigment changes of contents situation as shown in Figure 3 and Figure 4.
As can be seen from Figure 3 three kinds of products have whitening function to skin splash, after using 8 weeks, and product 1 mottle pigment
Reducing by 17%, product 2 is low by 14%, and Chinese medicine skin whitener reduces by 20%, but the onset time of different product is different, the Chinese medicine of the present invention
Whitening spot-relieving cream onset time is later, just has obvious change after using one month.Through the analysis of 8 weeks, Chinese medicine whitening
Frost has significantly effect to mottle, and the skin colourity in pilot region is decreased obviously (as shown in Figure 4).Chinese medicine whitening of the present invention
Light speckle frost may further promote the horn cell containing melanocyte in addition to suppressing melanic synthesis and come off, or makes melanin thin
