Problems solved by technology

Most of the spots on our skin are caused by the deposition of local melanin in the skin. When the melanocytes are stimulated by ultraviolet radiation, they will produce melanin and transfer to the stratum corneum to cause the skin to become dark. Gradual shedding of old cells
[0004] However, with the increase of age, or the pressure of life and work, the stimulation of the external environment, etc., the metabolic rate of skin keratinocytes will decrease. Too slow renewal causes the accumulation of old cells on the skin, which also makes the skin appear dull, and the spots are more obvious, making people look very tired and lifeless

preparation example Construction

[0057] The invention discloses an essence milk composition with the effect of lightening spots and brightening and a preparation method thereof. The main blemish-brightening ingredients of the essence milk composition include: undecylenoyl phenylalanine, lactic acid bacteria fermentation lysate, navel laver extract, lentil seed extract, which have the ability to inhibit the production of melanin, strengthen Efficacy of stratum corneum metabolism. Through the optimal combination and efficacy test, the most optimal composition ratio is found, and the synergistic effect of improving skin spots, dullness and other problems is obtained.

[0058] Among them, undecylenoyl phenylalanine is a melanotropic hormone (α-MSH) receptor antagonist, which controls its binding to melanin production factors, can effectively inhibit the activity of tyrosinase, and reduce melanin from the source , so as to reduce the deposition of skin pigment, improve pigmentation, brighten skin tone, and also p...

Embodiment 1-3

[0065] An essence milk composition with the effect of lightening spots and brightening, the ratio of raw material components is shown in Table 1 below.

[0066] The raw material component distribution ratio (unit: mass %) of table 1 embodiment 1-3

[0067]

[0068]

[0069] The preparation process of the essence milk composition with blemishes and brightening in the above-mentioned embodiment 1 comprises the following steps:

[0070] 1) Extraction of navel laver extract:

Abstract

The invention discloses an essence emulsion composition with freckle-fading and brightening effects and a preparation method thereof. The essence emulsion is prepared from the following raw material components in percentage by weight: 0.5-30 percent of spot-fading and brightening functional components and 70-99.5 percent of cosmetic auxiliary material matrixes. The components with the freckle fading and brightening effects comprise undecylenoyl phenylalanine, a lactobacillus fermentation lysate, a porphyra umbilicis extract and a lens culinaris seed extract; and the cosmetic auxiliary material matrixes comprise an emollient, an emulsifier, a filler, a thickener, a preservative, a pH regulator, daily essence and deionized water. According to the essence emulsion composition with freckle-fading and brightening effects, the generation of melanin can be inhibited, the deposition of melanin can be reduced, the metabolism of epidermis can be increased, skin regeneration can be promoted, the dark yellow and dim skin can be improved, future freckles and currently formed freckles can be prevented or reduced, the effects of uniformizing the skin color and brightening the skin can be achieved, and the complexion image effect of people is improved.

Description

technical field [0001] The invention relates to a skin care product and a preparation method thereof, belonging to the technical field of daily chemicals, and more specifically relates to an essence milk composition with the effect of lightening spots and a brightening effect and a preparation method thereof. Background technique [0002] Having a beautiful, clean and supple skin is the dream of every beauty lover. However, with the passage of time and the influence of environmental factors, it is extremely troublesome to have pigmentation on the face.
