Description

Cosmetic composition containing extract of Malva Sylvestris or Extract of Malva Sylvestris and Pinus Strobus bark for skin whitening}

The present invention relates to a cosmetic composition for skin whitening, and more particularly, mellow (mallow, generic name: Malva Sylvestris) extract or mellow extract and Pinus strobus blood (Pinus Strobus bark) cosmetic composition for skin containing an extract as an active ingredient whitening It is about. Mellow extract of the present invention inhibits the production of intermediate products or end products (AGEs: Advanced Glycation End-products) by the protein glycation (Protein Glycation) reaction to prevent the functional damage of the biopolymers to brighten the skin color. In addition, strobe pine bark has an excellent antioxidant effect, inhibits tyrosinase activity and the production of melanin to help skin whitening.

Skin is a very important tissue that protects the human body and has biochemical and physical functions. The skin is divided into epidermis, dermis, and hypodermis. Melanin is a pigment present in the epidermal layer of the skin and is a biopolymer of phenols having a complex form of black pigment and protein. Melanin is reported to be biosynthesized mainly by the action of tyrosinase. Tyrosinase is an enzyme that binds to copper and promotes aerobic oxidation in phenolic compounds such as monohydroxy or dihydroxy phenylalanine (DOPA), and deposits melanocytes on the skin that is severely exposed to ultraviolet rays to prevent skin aging or damage. It acts as a trigger.

Tyrosine, an amino acid, is converted to dopa by an enzyme called tyrosinase, and then converted to dopaquinone, followed by oxidation to produce melanin. The melanin thus produced is transferred from melanocytes, which are melanocytes, to keratinocytes, which are keratinocytes, in the form of vesicles called melanosomes. The keratinocytes go through the keratinization process and gradually move outwards and away from the skin at the stratum corneum.

The blackening process of the skin serves to protect the skin from the harmful environment, but excessively produced melanin blackens the skin, which is not only a cosmetic problem but also causes skin cancer in severe cases. Therefore, many studies have been made to inhibit the skin blackening process. In particular, by inhibiting the melanin production process is to inhibit the function of the tyrosinase enzyme that plays a major role in the production of melanin. It inhibits tyrosine from being transformed into melanin by inhibiting the activity of tyrosinase enzymes such as chelation of copper ions, which is the key to tyrosinase enzyme activity, and reaction with tyrosinase competitively with tyrosine.

Arbutin, kojic acid, hydroquinone, vitamin C, and the like, commonly known as a whitening agent, are methods of inhibiting tyrosinase enzymes. However, these conventional whitening agents have limitations in use such as poor stability in use, resulting in degradation or coloring or off-flavor, and limitations in efficacy at the biological level. Therefore, there is a demand for the development of a whitening material having excellent stability while having a stronger effect.

On the other hand, glycation in vivo (Glycation) is a reaction occurring between the reducing sugar such as glucose and the amino group of the protein damages the biopolymer such as protein. In particular, the skin becomes dull and loses elasticity as skin aging is promoted due to degeneration of proteins due to glycation. Therefore, the glycosylation reaction between reducing sugar and protein in the body such as glucose and fructose has been studied in association with diabetes complications and skin aging.

The inventors of the present invention, while looking for a glycation reaction inhibitory substance that fundamentally inhibits the production of AGEs, found that the mellow extract has an excellent safety and inhibitory effect on the glycation reaction, and confirmed that the skin whitening effect was obtained. Also, the mellow extract and the strobe pine extract were By mixing the more excellent skin whitening effect was found, to complete the present invention.

Therefore, it is an object of the present invention to provide a skin whitening cosmetics by containing a mellow extract as an active ingredient to inhibit the glycation reaction.
