Technical Field

The invention relates to a cosmetic, and particularly relates to a freckle-removing essence.

Background

At present, due to social progress and continuous improvement of living standard, people pay more attention to face care, especially asians, and care about various spots such as chloasma and freckles on the face, so various cosmetics such as freckle removing cream and freckle removing essence appear on the market. In the freckle-removing cosmetics in the last twenty years, whitening components such as kojic acid, arbutin, nicotinamide, VC and the like are added, and the freckle-removing cosmetics have certain whitening and freckle-removing effects, but the effects are not ideal and slow in effect.

In recent years, resorcinol derivatives are found to have super-strong potential whitening efficacy, and have the advantages of high whitening speed, discussion of the favor of consumers, in-vitro experiments also prove that the resorcinol derivatives are dozens of times or even hundreds of times stronger than VC, the whitening capability of the resorcinol derivatives is clinically proved to be comparable to that of hydroquinone, and through continuous understanding of the properties and safety of the raw materials for more than ten years, the resorcinol derivatives gradually acquire the permission of each country and are gradually used in cosmetics.

Phenylethyl resorcinol is one of the products of resorcinol. The whitening effect is more obvious. However, sufficient amount of phenylethyl resorcinol has a certain irritation to the facial skin, so that it can be effective while reducing the amount of addition thereof, which is a problem for cosmetic development engineers.

In order to solve the problems, the freckle removing essence is added with resveratrol, sodium hyaluronate and tranexamic acid besides phenethyl resorcinol.

The phenethyl resorcinol has excellent skin whitening effect, is one of tyrosinase inhibitors with the highest reported activity, and is 22 times of kojic acid; can effectively inhibit the activity of B16V cells for synthesizing melanin, which is 210 times of that of kojic acid. It can improve uneven skin color and reduce skin pigmentation caused by ultraviolet irradiation. Meanwhile, the phenethyl resorcinol is an excellent antioxidant and has the anti-wrinkle capability.

Resveratrol, a non-flavonoid polyphenolic organic compound, is an antitoxin produced when many plants are stimulated and has the chemical formula of C14H12O 3. Can be synthesized in grape leaf and grape skin, and is bioactive component in wine and grape juice. In vitro experiments and animal experiments show that resveratrol has antioxidant, antiinflammatory, anticancer and cardiovascular protecting effects. The researchers have verified that resveratrol has obvious inhibitory effect on melanoma cells through MTT method and flow cytometry.

Sodium hyaluronate, an inherent component in the human body, is a dextran aldehyde acid, has no species specificity, and is widely present in tissues such as placenta, amniotic fluid, crystalline lens, articular cartilage, skin dermis and the like; it is distributed in cytoplasm and intercellular substance, and has lubricating and nourishing effects on cells and cell organs contained therein.

Tranexamic acid is also called tranexamic acid and tranexamic acid, and is a protease inhibitor which can inhibit the catalytic action of protease on the hydrolysis of peptide bonds, thereby preventing the activity of enzymes such as inflammatory protease, inhibiting the disorder of epidermal cell functions of black spot parts, inhibiting melanin enhancement factor groups, and completely cutting off the generation path of melanin formed by ultraviolet irradiation, thereby achieving the effects of whitening and lightening the spots.

The whitening and freckle-removing essence has the advantages that the added core components play roles in whitening and removing freckles by different principles and different methods, the whitening and freckle-removing effects can be improved by matching the core components with each other, the pH value range of the whitening and freckle-removing essence is 6.5-7.5, the whitening and freckle-removing essence is neutral, and the whitening and freckle-removing essence is suitable for rapid transdermal absorption of human skin.
