Vitamin U, a patented ingredient for the exclusive use of CUSKIN Co., Ltd (Vitamin U Patent - Korea :10-1202006; Patent Application Number: 20110237671).
Vitamin U (cosmetic composition containing vitamin U as an active ingredient for wound healing and wrinkle reduction).

Vitamin U is a natural substance found in vegetables (broccoli, cabbage, etc.) and seaweed. Vitamin U is a derivative of the sulphur-containing α-amino acid (methionine), which has excellent anti-inflammatory properties and efficacy in protecting cells and improving cellular functions, with outstanding benefits for skin firmness and wrinkle reduction.

ABOUT VITAMIN U
- Causes wrinkles and dry skin
Skin wrinkles are caused by internal ageing due to physiological factors and external ageing due to ultraviolet radiation (photoageing). The main cause of wrinkles is dry skin and reduced elasticity. A characteristic feature of ageing skin is a significant reduction in skin elasticity due to a reduction in the amount of collagen and elastic fibres in the dermis. In addition, the skin becomes drier due to reduced sebum secretion and accelerated metabolism of the natural moisturising factor, leading to the formation of wrinkles.

- Basis for the invention
Vitamin U is known to be effective in the treatment of gastrointestinal ulcers. The composition of the mucous membrane of the digestive system is similar to that of the skin. Therefore, vitamin U has been used in cosmetic compositions on the premise that it can be very useful in the treatment of skin wounds and in the reduction of wrinkles, which can be broadly defined as a wound caused by time and UV radiation.

- Origin of vitamin U
Vitamin U was originally a substance known to be effective in the treatment of ulcers in the digestive system. The similarity of the composition of the mucous membrane of the digestive system has been invoked in the treatment of stomatitis or skin wounds. In fact, vitamin U has been shown to improve the condition of skin wounds, as well as to reduce wrinkles caused by internal ageing processes and external ageing due to ultraviolet damage.

- Properties of vitamin U
