It is precisely the condition of this collagen tissue (as well as hereditary factors, of course) that determines the skin appearance; whether the skin looks young or aged, smooth or wrinkled.

We can think skin is fragile, but it actually provides a strong and durable covering for the body. Skin protects from heat and cold. It protects from dehydration as well as from infections. Besides being important for the physical health, the skin is also important for your emotional health. At the end of the day, the way we look like is, in general, an expression of how we feel. Of course, care and some dose of common sense are needed to keep the skin fresh and smooth. Diet is as important as exercise.
