But this multitalented organ is much more than that. It provides us with one of our senses, it can draw oxygen directly from the air, and it can even perceive sound waves and odor molecules. The skin is also a status symbol, with smooth, wrinkle-free skin symbolizing youth, beauty and success. Countless experts offer advice, including recommending anti-aging products containing acids, bases, enzymes, vitamins, or proteins.
