Composition with whitening and spot-fading effects and application thereof

Abstract

The invention relates to a whitening spot-fading composition and an application thereof, and provides a whitening spot-fading facial mask with a remarkable effect. The composition with the whitening spot-fading effect provided by the invention includes the following components: 0.001-0.008% of frozen pear extract and 0.001-0.008% of orychophragmus violaceus extract. Through research, the applicants find that the frozen pear extract has better tyrosinase inhibitory activity than an unfrozen pyrus bretschneideri extract. The frozen pear extract and the orychophragmus violaceus extract have a significant synergistic effect after being compounded; and nutrient ingredients are added to a facial mask, so that playing of the whitening spot-fading effect of the frozen pear extract and the orychophragmus violaceus extract can be effectively promoted, and the whitening spot-fading effect of the facial mask can be obviously improved.

Description

technical field

[0001] The invention relates to the field of medicine, in particular to a composition with the effect of whitening and lightening spots and its application. Background technique

[0002] In recent years, with the acceleration of the pace of life and the intensification of environmental pollution, people are facing more and more skin problems, and dull skin and pigmentation have become common problems.

[0003] There are still some ambiguities about the mechanism of the above-mentioned dark complexion and pigmentation problems. It is generally believed that the abnormal growth of melanin or the uneven distribution of melanin caused by abnormal hormones or ultraviolet rays from sunlight are the main reasons. The metabolic pathway of melanin has been relatively clear: in melanocytes, tyrosine is gradually transformed into true melanin through intermediates such as dopa, dopaquinone, dopachrome, and dihydroxyindole under the action of enzymes such as tyrosinase. ...

Examples

Embodiment 1

[0031] Embodiment 1: the preparation of frozen pear extract

[0032] Frozen pear extract is prepared by the following method: take ripe white pear fruit, freeze it at -16°C for 70 days, take it out, put it in cold water, soak it for 30 minutes, remove the ice shell outside the fruit, squeeze the fruit juice, and vacuum the obtained juice Concentrate and dry with a freeze dryer to obtain the frozen pear extract.

Embodiment 2

[0035] Embodiment 2: the preparation of February blue extract

[0036] Take the dried whole herb of Erchis japonica, soak it in methanol for 10 hours at room temperature, filter, concentrate the extract under reduced pressure, and dry it into powder to obtain the Erchis japonica extract.

[0037] Composition 1: Preparation of Composition 1

[0038] The extracts of Example 1 and Example 2 were weighed according to the mass ratio of 1:1, and mixed evenly to obtain Composition 1.
