Excess skin is an effect of surplus skin and fat after expansion during pregnancy or adipositas and following a massive and considerable weight loss. Further reasons can be aging effects, genetic disorders or an intentional expansion for skin reconstruction.
A unique or very rare case of excess skin in a human is described in this Youtube video about an Australian boy born in 1993 with a great excess of skin, which hung about him in many wrinkles. As he grew towards adulthood, he "grew into" his skin, as into an oversize garment, and the wrinkles flattened out. His condition is compared to Shar Pei dog puppies, which have this condition also; the boy and Shar Pei puppies in their skins both have 100 times the normal level of hyaluronic acid.
