Prepare the application for having and subtracting in the cosmetics or skin care item that wrinkle is brightened, the tender skin of moisturizing and ultraviolet radiation preventing are acted on.
The present invention achieves following beneficial effects:
1st, essence of the present invention is right using the recombinant human metallothionein tunning extract obtained by gene recombination technology
Many kinds of metal ions has compatibility and removes free radical effect, can be effectively improved skin microcirculation, promotes skin regeneration;With good
The good tender skin of moisturizing, subtract wrinkle whitening efficacy.
2nd, essence of the present invention uses recombinant human metallothionein tunning extract for through saccharomycete, lactic acid bacteria or big
Extraction purification gained crude extract after enterobacteria fermentation, surprisingly, its anti-aging, radioresistance effect are better than simple metal sulphur egg
In vain, and crude extract be easier obtain, its yield is higher, cost is lower.
3rd, liquid crystal type essence of the present invention be acted on by the molten cause between each composition to be formed between liquid and crystal, pure solid
Intermediateness between body, the liquid crystal type essence is compared with skin sense comfort level, the permeability to skin, the moisturizing with common essence
Property more preferably, and also there is control Trenaxmine, rate of release effect of metallothionein etc..
Essence white-skinned face function of the embodiment 6. comprising recombinant human metallothionein yeast tunning extract is evaluated
After qualified subject signs Informed Consent Form, determine the pigment content and skin color of its cheek and provide
Tested essence.Subject continuously uses essence of the invention (that is, the product of embodiment 1), sooner or later each daily to use 1 time,
Application after face cleaning.Other skin-lightening cosmetics are disabled during testing, it is continuous to use 30 days, after 60 days, then in kind determine
Each efficacy measures (Figure 1A-F).In addition trial employment period inquiry subject is after product using feeling and whether there is allergic phenomena etc.,
Contrast before and after itself is recorded, while setting up metallothionein essence (that is, includes the proof gold of 4 weight % in the control essence
Category sulfoprotein, the product of other compositions and corresponding content with embodiment 1 is consistent) control group.
Skin color difference meter testing result shows that it is the flat of value to use the product different time skin of face color of embodiment 1
Average and standard deviation are shown in Table 6-8.Normal human facial skin's each detected value no significant difference of color difference meter, during showing experiment
Skin color natural fluctuation is not obvious.Using product 30 days (i.e. 30d), L* values are higher than basic value (0d), difference tool to the heavy patient of color afterwards
Statistically significant (p < 0.05);A* values are substantially reducing (P < 0.05) afterwards using product the 60th day (i.e. 60d), b* value changes
It is not statistically significant.From in terms of amplitude of variation, the product of embodiment 1 check colors heavy skin improvement compared with metallothionein Essence
Control group is good (data are shown in Table 6-8).
Table 6. using embodiment 1 product volunteer different time skin color value L values comparing (n=30,)
Note:Compare with 0d, * P < 0.05, * * P < 0.01
Table 7. using embodiment 1 product volunteer different time skin color value a* values comparing (n=30,)
Note:Compare with 0d, * P < 0.05, * * P < 0.01
Table 8. using embodiment 1 product volunteer different time skin color value b* values comparing (n=30,)
Note:Compare with 0d, * P < 0.05, * * P < 0.01
Dermal melanin index (MI) and haematochrome index (EI) average value and standard deviation are shown in Table 9-10, as a result show, make
Basic value is less than with the melanin index of the heavy patient skin of color after product the 56th day, difference is statistically significant (P < 0.01), red
Pigment indices are at the 56th day obviously higher than basic value (P < 0.01).
The volunteer's melanin index M I datum statistical form of table 9. (n=30,)
Note:Compare with 0d, * P < 0.05, * * P < 0.01
The volunteer's melanin index E I datum statistical form of table 10. (n=30,)
Note:Compare with 0d, * P < 0.05, * * P < 0.01
The above results absolutely prove that it is black that essence (that is, the product of embodiment 1) of the invention can be effectively improved the heavy patient of color
Pigment deposition situation, with whitening effect.From in terms of amplitude of variation, the product of embodiment 1 check colors heavy skin improvement it is golden
Category sulfoprotein Essence control group is good.This explanation prepares essence etc. and changes using recombinant human metallothionein tunning extract
Cosmetic can obtain the effect that cosmetics are prepared better than simple metal sulfoprotein, and production cost and difficulty can be reduced again, be more suitable for big
The industrial production of scale.
Although it should be understood that with reference to its exemplary embodiment, particularly shown and description is carried out to the present invention,
It should be understood by those skilled in the art that without departing substantially from the spirit of the invention as defined in appended claims
Under conditions of scope, the change of various forms and details can be wherein carried out, any of various embodiments can be carried out
Combination.
