Description

Hyaluronic acid production promoter

The present invention relates to a hyaluronic acid production promoter, a hyaluronic acid production-promoting food or drink, and a hyaluronic acid production-promoting cosmetic material which are useful for preventing skin roughness, wrinkles, and elastic decline. More specifically, the present invention relates to a hyaluronic acid production promoter which is an active ingredient of a lactoperoxidase decomposition product obtained by decomposing lactoperoxidase and/or lactoperoxidase with a proteolytic enzyme.

In recent years, studies on skin machine turnover have progressed. In addition to the deterioration of the skin due to age, in addition to the deterioration of metabolism due to age, it is complicated to involve ultraviolet rays, drying, and oxidation of sunlight. And the like (Non-Patent Documents 1 and 2). It is understood that these factors cause a significant decrease in hyaluronic acid which is a main matrix component of the dermis (Non-Patent Document 3). Hyaluronic acid retains moisture in its molecules, thereby having the function of keeping the skin supple. However, if the hyaluronic acid is destroyed by these effects, the moisture retaining mechanism of the skin is damaged, the skin becomes dry and becomes rough, and wrinkles or slack increase.

As such an agent for improving the moisture retention function of the skin, many cosmetic materials such as hyaluronic acid or collagen have been proposed, but these only exert a moisturizing effect on the surface of the skin, and do not substantially improve the function of the skin. . In addition, vitamins or crude drugs have been used as skin cell activating agents, but the current situation has not yet reached the realm of treating skin function decline. In view of the above, it is desirable to have a hyaluronic acid production promoter which is resistant to skin wrinkles or slack by promoting the synthesis of hyaluronic acid which is a main component of the dermis layer, and which is not problematic in terms of safety.

On the other hand, hyaluronic acid in the joint fluid functions to cover the surface of the articular cartilage, so that the joint function can be smoothly operated. The concentration of hyaluronic acid in normal joint fluid is about 2.3mg/mL, but for example, in the case of rheumatoid arthritis, the hyaluronic acid concentration in the joint fluid drops to about 1.2mg/mL, and the viscosity of the joint fluid also drops significantly. Patent Document 4). In addition, septic arthritis, gouty arthritis, and the like are also known to cause a decrease in hyaluronic acid content as in the case of rheumatoid arthritis (see Non-Patent Document 5).

In the above diseases, in order to improve the lubrication function, the articular cartilage is covered. Protection, pain suppression, and improvement of the symptoms of pathological joint fluids are measures for increasing the amount of hyaluronic acid in the synovial fluid. For example, it has been considered that the above-described improvement can be achieved by performing a joint injection therapy of sodium hyaluronate in a rheumatoid arthritis patient (Non-Patent Document 6). Similarly, in traumatic joint disease, degenerative arthritis, or osteoarthritis, joint injection therapy of hyaluronic acid has been reported to have an effect of improvement (Non-Patent Document 7). From the above, it is known that the promotion of hyaluronic acid is effective for prevention and treatment of joint diseases such as skin diseases such as rough skin, rheumatoid arthritis or traumatic joint disease, degenerative arthritis, and deformed arthritis. However, the treatment of the above diseases requires long-term and requires a doctor's prescription. Therefore, it is desired to have a cream or food or drink containing a hyaluronic acid production promoter which can be easily treated in daily life.
