Did you ever wonder what makes the skin so supple after using a cream, or lotion? What part of an anti wrinkle cream protects it from dryness? Well, it is hyaluronic acid, or hyaluronan.
Hyaluronic acid (HA) is basically a carbohydrate that is found naturally in every part of our body. Fluids in our eyes and joints have the highest concentrations of HA. This carbohydrate polymer is a component of our connective tissues, and has different functions depending on its location in the body.
For instance, it acts as a cushion for joints, and as a binding material in ligaments and tendons. HA often binds with water and forms a gel-like substance. This substance also helps in wound healing, and reducing inflammation.
HA and its relation with the skin
Skin is the largest organ of a human body. It accounts for about 50 percent of the total hyaluronic acid present in our body. Our skin needs HA and collagen, a protein and main component of connective tissues, for staying firm and soft. Collagen gives firmness and elasticity to the skin. Without moisture, collagen becomes prone to breaks and tears, making our skin rough, and sometimes flaky. HA plays the most important role here by hydrating the collagen, and returning the skin its elasticity and firmness. HA also acts as a space filler between skin cells, and thus makes our skin wrinkle free.
Cosmetic manufacturers often add HA to their beauty products, especially an anti-wrinkle cream, due to its natural benefits. HA that generates naturally in our skin cells degrades with each passing day. It happens to be the most important ingredient of every skin cream, or lotion, as it makes the skin retain that natural satin look and feel.
