In dermatology, skin is the largest organ of the integumentary system made up of multiple layers of epithelial tissues that guard underlying muscles and organs. Skin pigmentation varies among populations, and skin type can range from dry skin to oily skin. As the interface with the surroundings, skin plays the most important role in protecting (the body) against pathogens. The use of natural or synthetic cosmetics to treat the appearance of the face and condition of the skin (such as pore control and black head cleansing) is common among many cultures. Oily skin can be cleaned quickly with a mild solution of detergent, when pure bath soaps fail. Afterward, body lotions could be used to recondition cleansed skin, as would be used to treat dry skin.
Collagen is one of the long, fibrous structural proteins whose functions are quite different from those of globular proteins such as enzymes; tough bundles of collagen called collagen fibers are a major component of the extracellular matrix that supports most tissues and gives cells structure from the outside, but collagen is also found inside certain cells. Along with soft keratin, it is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging. It strengthens blood vessels and plays a role in tissue development. It is also used in cosmetic surgery and burns surgery.
In this study, plant collagen extracts from yellow cucumber has been used to investigate the effect of the extracts on the human skin conditions. Good skin condition was attributed to the cucumber extracts probably due to the plant collagen ingredients in it. The total test period was 4 weeks and the number of patients were 10. The balance of oil and water contents in the skin were stabilized after the use of the extracts. The skin roughness was improved throughout the whole patients.
