What is a common characteristic of aging skin?

A) Increased permeability to moisture
B) Diminished sweat gland activity
C) Reduced oxygen-free radicals
D) Overproduction of elastin

Aging skin tends to be drier.Sweat gland activity is diminished.The skin's connective tissue,collagen,and elastin are reduced,which means the skin loses firmness and so wrinkles.Skin aging also occurs with exposure to oxygen-free radicals that are waste products from chemical reactions in the body as well as with exposure to certain food and environmental sources.An infant's skin is thinner and more permeable to moisture in the environment.
