Cucumbers such as gherkins that are specially cultivated to make pickles are oftentimes much smaller than slicing cucumbers.

The silica in cucumber is an essential component of healthy connective tissue, which includes muscles, tendons, ligaments, cartilage, and bone. Cucumber juice is often recommended as a source of silica to improve the complexion and health of the skin, plus cucumber's high water content makes it naturally hydrating—a must for glowing skin. Cucumbers are also used topically for various types of skin problems, including swelling under the eyes and sunburn. Two compounds in cucumbers, ascorbic acid and caffeic acid, prevent water retention, which may explain why cucumbers applied topically are often helpful for swollen eyes, burns and dermatitis.
