Freckle-removing essence and preparation process thereof

Abstract

The invention discloses freckle-removing essence and a preparation process thereof. According to the technical scheme, the essence is prepared from the following components in parts by weight: 2-3 parts of vitamin C derivative, 0.8-1.5 parts of vitamin E, 1-2 parts of nicotinamide, 1-1.2 parts of acetyl chitosamine, 2-5 parts of angelica extract, 1-2 parts of titanium dioxide, 10-15 parts of humectant, 0.2-0.5 part of antibacterial preservative and 80-120 parts of deionized water. By adopting the technical scheme, a quick freckle-removing effect can be achieved, and the traditional Chinese medicine components can achieve the freckle-removing effect as well as gradually consolidate the freckle-removing curative effect.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a freckle-removing essence and a preparation process thereof. Background technique [0002] Pigments are spots that are a different color from the surrounding skin. Including freckles, dark spots, chloasma and age spots, etc., which belong to pigmented disordered skin diseases. It is a common skin disease with brown or hyperpigmentation and disfigurement on the face due to the increase of skin melanin. It mainly occurs on the cheeks and forehead, and is aggravated after sun exposure. It is more common in women and is related to pregnancy and long-term menstrual disorders. [0003] The Chinese patent with the application number 201520564525.2 discloses a freckle-removing essence whose main components are traditional Chinese medicine ingredients. Although the Chinese medicine ingredients can play the role of freckle-removing effects, the simple Chinese medicine ingredients are slow to tak...

Problems solved by technology

[0007] Through the above settings, after the vitamin C derivatives are absorbed by the skin, they will be decomposed by the enzyme system inside the skin and reduced to vitamin C. The vitamin C derivatives not only retain the physiological activity of vitamin C, but also improve the instability and The skin is non-absorbable, can penetrate into the base layer of the skin instantly, is not easy to oxidize, has high stability, is safe and non-irritating, and the reduced vitamin C can directly restore melanin, reducing melanin to colorless reduced melanin, so as to achieve whitening of the skin , the effect of lightening spots, but because the reduced melanin may still be oxidized again, so the whitening products with vitamin C derivatives as functional ingredients must maintain sufficient concentration and persist for a long time to achieve the effect, and vitamin C derivatives also It can reduce o-quinone through its own antioxidant activity, and inhibit the activity of catalase to achieve the effect of inhibiting melanin production; on the one hand, the addition of vitamin E can prevent skin damage caused by ultraviolet rays and polluted air, and promote skin regeneration. Metabolism, prevent pigmentation, improve skin elasticity, moisturize the skin, on the other hand, promote skin metabolism can prevent pigmentation, improve skin elasticity, moisturize the skin, play a role in beauty, skin care, and anti-aging; Niacinamide can down-regulate melanin Cell-to-keratinocyte melanosome transport without inhibiting tyrosinase activity or cell proliferation, thereby affecting skin pigmentation, it also interferes with cell signaling pathways between keratinocytes and melanocytes, reducing Melanogenesis, on the other hand, nicotinamide can act on the already produced melanin, reducing its transfer to the surface cells, and nicotinamide also has anti-aging, improving skin barrier function, moisturizing, oil control and shrinking pores; acetyl chitosan Amines can inhibit the glycosylation of tyrosinase, inhibit the maturation of tyrosinase, thereby inhibiting the synthesis of melanin, inhibit the increase of the spot area, reduce the deepening of skin color and uneven skin color caused by ultraviolet rays, and reduce pigmentation to a certain extent Angelica extract can promote skin metabolism, regulate skin immune function, inhibit skin melanin production, inhibit free radical damage to skin, enhance skin superoxide dismutase activity, prevent abnormal changes in skin, and maintain The ecological balance of the skin, the skin maintenance effect of preventing skin diseases; ultraviolet rays are very harmful to the human body, titanium dioxide is white, chemically stable, non-toxic, neutral, and nano-titanium dioxide is an inorganic component, with excellent chemical stability , thermal stability, non-migration and strong decolorizing power and hiding power, and nano-titanium dioxide technology absorbs ultraviolet rays and can emit and scatter ultraviolet rays, so it has strong anti-ultraviolet ability, and because of the finer particles, the finished product has high transparency , can pass through visible light, the skin whiteness is natural when used in cosmetics, overcomes the opacity of some organic matter or pigment grade titanium dioxide, and makes the skin appear unnatural pale defects; the addition of moisturizers can improve skin dryness, obviously Increase the water content of the skin, increase skin elasticity, and prevent skin damage and promote damaged skin repair; the addition of antiseptic and antibacterial agents can slow down the corrosion of cosmetics Deionized water can effectively dissolve some components of cosmetics, and the price is low, and it can also play a role in replenishing water. The combination of traditional Chinese medicine and chemical components in the entire component can Achieve rapid freckle removal effect, and can consolidate the curative effect
